Local AI Strategy for Z890-AI Top, Z490 RTX 3090, and Omen17 RTX 3070 Ti
|
Table of Contents
|
Purpose: This page gives a practical local-AI plan for my available machines:
- Main machine: Z890-AI Top + dual RTX 5090 = 32 GB + 32 GB = 64 GB VRAM, 256 GB RAM
- Second machine: Z490 + RTX 3090 24 GB VRAM, 128 GB RAM
- Laptop: Omen17 + RTX 3070 Ti 8 GB VRAM, 64 GB RAM
- Large local model available: public Grok-2 copy on HDD, approx. 298 GB
The goal is not to chase fashionable AI claims, but to build useful local systems for Sanskrit corpus work, Jyotiṣa rule modelling, MBFR documents, pure-Hindi generation, code assistance, video/text pipelines, and tabular forecasting such as gold, rainfall, weather, and related numeric models.
1. Corrected Starting Point
The older notes contained useful ideas but also stale or over-optimistic claims. The corrected position is this:
Grok-2 is locally present as a 298 GB public copy, but it should not be assumed to be easily trainable or fast on dual RTX 5090.
It should be treated as a large experimental local model for inference, batch reasoning, comparison, and perhaps adapter experiments only after successful serving tests.
The official xAI/Hugging Face instructions for their Grok-2 repository describe a much larger expected folder and a server launch using tensor parallelism across 8 GPUs, each with more than 40 GB memory. Therefore, my 298 GB copy is likely a different packaging, quantization, or checkpoint layout. It may still be useful, but it must be tested empirically.
1.1 What Must Not Be Assumed
Do not assume:
- that Grok-2 will load directly into 64 GB VRAM
- that it will run fast from HDD
- that QLoRA/PEFT training on Grok-2 will be straightforward
- that Grok-2 is the best model for deterministic rule systems
- that a 298 GB model automatically gives better results than a well-tuned 30B–34B model for my own rule-based domains
1.2 What Can Be Assumed
The following assumptions are reasonable:
- Z890 dual RTX 5090 is excellent for 30B–34B local model work
- RTX 3090 is excellent for 24B–34B quantized inference, dataset preparation, embeddings, and smaller training jobs
- Omen17 RTX 3070 Ti is useful for light inference, preprocessing, coding, testing, and data cleaning
- Grok-2 can be investigated as a large local inference model, especially if available in a format usable by llama.cpp, SGLang, vLLM, or another backend
- HDD should be treated as archive storage, not ideal runtime storage for large model inference
2. Hardware Roles
2.1 Z890-AI Top + Dual RTX 5090 + 256 GB RAM
Primary role: serious model experimentation, 30B–34B fine-tuning, QLoRA, RAG indexing, document pipelines, batch inference, and high-throughput ML.
Best uses:
- full or near-full fine-tuning experiments on 7B–14B models
- QLoRA/LoRA fine-tuning on 30B–34B models
- multi-GPU inference for 30B–70B quantized models
- Sanskrit/Purāṇa corpus embedding and retrieval
- MBFR document assistant
- pure-Hindi style model/adapters
- code-assistance models for VB6, C++, Python, HTML, Wikidot, and batch scripts
- tabular ML training for gold/rainfall/weather using MLP, XGBoost, LightGBM, etc.
- video pipeline assistance and script generation
This is the machine where most serious AI work should happen.
2.2 Z490 + RTX 3090 + 128 GB RAM
Secondary role: inference server, embeddings server, smaller LoRA work, RAG backend, validation machine, and batch preprocessing.
Best uses:
- serve a 14B–32B quantized model
- run embedding models continuously
- build vector databases
- test fine-tuned adapters before deployment
- process Sanskrit text, CSVs, and corpus chunks
- run DeOldify/Real-ESRGAN style pipelines where RTX 3090 is already stable
- compare outputs against the Z890 model
The RTX 3090 remains very valuable because of its 24 GB VRAM and mature CUDA compatibility.
2.3 Omen17 + RTX 3070 Ti 8 GB + 64 GB RAM
Portable role: testing, lightweight inference, script development, dataset inspection, small models, and remote access to the main machines.
Best uses:
- run 3B–8B quantized models
- test prompts and dataset formatting
- prepare CSV/JSONL training samples
- run small embedding jobs
- remote desktop / SSH / web UI access to Z890 and Z490
- light coding assistant
- emergency inference when away from main machines
The Omen17 should not be forced to run huge models locally. Its value is mobility and control.
3. Model Strategy: Do Not Use One Model for Everything
The correct architecture is multi-model, not one giant model doing all tasks.
Wrong strategy: “Use Grok-2 for everything: Jyotiṣa, Sanskrit grammar, gold prediction, weather prediction, MBFR, code, pure Hindi, and corpus retrieval.”
Correct strategy: Use different model types for different tasks:
- LLM for language and reasoning
- RAG for document-grounded answers
- MLP/tabular models for numeric prediction
- rule engine for deterministic logic
- small router to decide which subsystem should answer
3.1 Recommended Role Division
| Task | Best System |
|---|---|
| Pure conversation, explanation, essay drafting | 24B–34B instruct LLM; optionally Grok-2 if it runs acceptably |
| Sanskrit/Purāṇa retrieval | RAG + embeddings + reranker + LLM explanation |
| Jyotiṣa deterministic rule engine | VB6/C++/Python rule engine + structured output, not free-form LLM |
| PhalitaGPT explanation layer | Rule engine first, LLM second |
| Gold/weather/rainfall numeric prediction | MLP / tabular ML, not LLM |
| Pure Hindi generation | LLM with style dataset + lexical filter |
| MBFR Q&A | RAG over my MBFR documents + LLM synthesis |
| Code assistant | Qwen Coder / DeepSeek Coder / similar local model, plus general LLM |
| Grok-2 | experimental large-model inference, batch reasoning, comparison, and possibly style/adapters if feasible |
4. Grok-2: Mostly Frozen Adapter Use
Correct use of my local Grok-2 copy:
I am not planning to fully fine-tune Grok-2. I am planning to keep the Grok-2 backbone mostly frozen and train only a small project-specific adapter using PEFT/LoRA/QLoRA-style methods, if the model format and loading backend allow it.
My local Grok-2 copy is approximately 298 GB and is publicly accessible. It should be treated as a valuable large-model base for one carefully chosen adapter experiment, not as a model whose main weights should be altered.
4.1 What “Mostly Frozen Grok-2” Means
In this approach:
- the original Grok-2 weights remain unchanged
- only a small number of adapter parameters are trained
- the trained output is saved separately as a small adapter
- the base Grok-2 model can be reused unchanged
- the adapter can be loaded only when that project is needed
This is not full fine-tuning. It is a controlled method for adding one project-specific behaviour without corrupting the main model.
4.2 Why This Is Useful
A frozen Grok-2 backbone can retain its general reasoning, language, and broad knowledge, while the adapter teaches it one specific discipline or response-pattern.
Possible adapter projects:
| Adapter Project | Purpose |
|---|---|
| Pure-Hindi style adapter | generate Hindi avoiding Urdu/Persian/Arabic vocabulary where required |
| MBFR explanation adapter | explain MBFR concepts using my terminology and structure |
| Jyotiṣa explanation adapter | explain already-computed rule-engine outputs without inventing calculations |
| Sanskrit corpus assistant adapter | improve response style for Sanskrit/Purāṇa passages retrieved by RAG |
| Wikidot writer adapter | produce clean Wikidot edit-mode pages with headings, colour blocks, and formatting |
The best first project should be small, sharply defined, and easy to evaluate.
4.3 Best First Grok-2 Adapter Project
The first Grok-2 adapter should not be gold prediction, rainfall prediction, or any numeric forecasting model. Those belong to MLP/tabular models.
The best first Grok-2 adapter should be one of these:
- Pure-Hindi style adapter
- MBFR explanation adapter
- Wikidot formatting adapter
- Jyotiṣa explanation-only adapter
Among these, the safest first experiment is:
Recommended first Grok-2 adapter: Pure-Hindi + Wikidot writing adapter.
Reason: output quality is easy to judge, the task is linguistic rather than numerically deterministic, and failure will not corrupt any scientific or forecasting workflow.
4.4 Practical Training Method
The training should be done as follows:
- keep Grok-2 base weights frozen
- load the model with the lightest working backend
- train only LoRA/PEFT adapter layers
- use a small curated dataset first
- compare base Grok-2 output vs adapter output
- save only adapter weights
- do not merge adapter into the base model until extensive testing is complete
4.5 Suggested Adapter Settings
Initial conservative settings:
| Parameter | First Test Value |
|---|---|
| LoRA rank | 4 or 8 |
| LoRA alpha | 16 or 32 |
| dropout | 0.05 |
| target modules | attention projection layers first, exact names discovered from model structure |
| batch size | smallest stable value |
| gradient accumulation | increase if needed |
| sequence length | begin small, then increase after stability |
| dataset size for smoke test | 100–500 examples |
| dataset size for first real test | 2,000–10,000 examples |
Do not begin with a huge dataset. First prove that the adapter changes behaviour in the intended direction.
4.6 Dataset Format
For a pure-Hindi/Wikidot adapter, use examples like:
{
"instruction": "Rewrite the following material in clean Wikidot edit mode using pure Hindi where appropriate, preserving technical English terms.",
"input": "Raw notes or rough markdown text here.",
"output": "+ Main Heading\n\n[[div style=\"background:#f0fdf4;border-left:6px solid #16a34a;padding:12px 16px;margin:12px 0;border-radius:8px;\"]]\n**Corrected polished text here.**\n[[/div]]"
}For MBFR:
{
"instruction": "Explain this MBFR section in a clear technical style without exaggeration.",
"input": "Retrieved MBFR notes, assumptions, equations, or draft section.",
"output": "Structured explanation with assumptions, limits, and conclusion."
}For Jyotiṣa explanation:
{
"instruction": "Explain this computed Jyotiṣa result. Do not invent chart data.",
"input": {
"computed_factors": "...",
"rules_applied": "...",
"conflicting_factors": "..."
},
"output": "Explanation based only on the supplied factors."
}4.7 Important Boundary
Grok-2 adapter training should be used for language, explanation, structure, and reasoning style.
It should not replace:
- my VB6/C++ deterministic Jyotiṣa calculations
- my rule-engine logic
- my MLP models for gold/weather/rainfall
- my RAG database for Sanskrit, Purāṇas, MBFR, or research documents
Correct relation:
Exact computation / retrieval / prediction
↓
Structured facts
↓
Frozen Grok-2 + small adapter
↓
Clear explanation / pure Hindi / Wikidot / synthesis4.8 Hardware Use
The Z890 dual RTX 5090 machine should be used for this Grok-2 adapter experiment.
The Z490 RTX 3090 machine should support:
- dataset preparation
- RAG indexing
- embeddings
- evaluation
- comparison with smaller models
The Omen17 should be used for:
- editing datasets
- running small tests
- remote control
- reviewing outputs
4.9 Final Rule for Grok-2
Grok-2 should be used as a mostly frozen large reasoning and language base.
Only one small, sharply defined adapter should be trained first.
The adapter should improve style, structure, and domain explanation — not replace deterministic computation or numeric ML models.
5. Serious Rule-Based Work: Use 30B–34B Local Models, Not Grok-2 First
For my serious deterministic domains, a smaller but controllable model is better than a huge model that cannot be controlled.
5.1 Suitable Domains
Use 30B–34B local models for:
- PhalitaGPT explanation layer
- Sanskrit grammar assistant
- pure-Hindi generation
- MBFR document assistant
- Vedic corpus summarization
- Jyotiṣa rule explanation
- code generation for VB6/C++/Python
- structured response generation from rule-engine outputs
5.2 Why 30B–34B Is the Practical Sweet Spot
30B–34B models are large enough to reason well, but small enough to:
- load on dual RTX 5090 in quantized form
- fine-tune using QLoRA
- run on RTX 3090 in smaller quantizations
- produce acceptable speed
- allow repeated experiments
- avoid the enormous overhead of Grok-2
5.3 Candidate Model Families
The exact model should be chosen after testing, but the practical candidates are:
| Model Family | Use |
|---|---|
| Qwen 3 / Qwen 2.5 32B | strong multilingual, reasoning, code, and general use |
| Yi 34B / Yi 1.5 34B | strong open-weight 34B option |
| Mistral Small 24B | efficient, strong general assistant, long context variants |
| Qwen Coder 32B | code generation, script writing, conversion, debugging |
| smaller 7B–14B models | fast router, classifier, assistant for laptop |
5.4 Full Fine-Tuning vs QLoRA
Important distinction:
For 30B–34B models, true full fine-tuning is expensive and risky. QLoRA/LoRA is usually the first practical method. Full fine-tuning should be attempted only for smaller models or after the dataset is proven.
| Method | Practical Meaning | Use |
|---|---|---|
| Full fine-tuning | update all model weights | only for smaller models or final serious experiments |
| LoRA | train adapter matrices, base model unchanged | best first step |
| QLoRA | quantized base model + LoRA adapters | best practical method for 30B–34B |
| Continued pretraining | train on raw corpus text | useful for Sanskrit/Hindi corpus adaptation but must be done carefully |
| SFT | instruction-response training | best for assistant behavior |
| DPO/ORPO/KTO | preference tuning | later stage, after good SFT |
For my work, the order should be:
- Build clean dataset
- Train small model first
- Test outputs
- Train 30B–34B QLoRA
- Compare with rule engine
- Add RAG
- Only then consider deeper/full tuning
6. PhalitaGPT and Jyotiṣa: Correct Architecture
6.1 Do Not Let an LLM Invent Predictions
For Jyotiṣa, the LLM must not be the primary predictor.
The primary predictor should be my deterministic rule engine, classical rule database, computed chart features, varga features, dasha/gochara features, and tested scoring models.
Correct architecture:
- VB6/C++ astrology engine computes chart and varga features
- Rule engine applies classical rules
- ML/regression layer estimates weights where needed
- LLM explains the result in human language
- RAG supplies textual support from classical corpus
- Final output cites rule sources and computed factors
6.2 PhalitaGPT Layer Separation
| Layer | Responsibility |
|---|---|
| Calculation engine | exact astronomy/chart/varga/dasha calculations |
| Rule engine | deterministic application of Jyotiṣa rules |
| Statistical layer | weight estimation from large horoscope database |
| RAG layer | retrieve classical verses/commentaries |
| LLM layer | explanation, synthesis, report writing |
| Human review | final judgment for serious cases |
6.3 Output Discipline
PhalitaGPT should output:
- computed facts
- applied rules
- rule weights
- conflicting indications
- final synthesis
- confidence level
- uncertainty causes
- references to retrieved corpus passages
It should not output vague soothing language.
7. Sanskrit Grammar and Pure Hindi
7.1 Sanskrit Grammar
Sanskrit grammar is symbolic, layered, and rule-bound. Therefore:
- use LLM for explanation
- use rule engine for derivation
- use corpus lookup for examples
- use constrained output formats where possible
- avoid allowing the base model to “guess” grammatical derivations
Recommended modules:
| Module | Function |
|---|---|
| Sandhi engine | deterministic phonetic transformations |
| Subanta/tiṅanta analyzer | |
| Dhātu database | |
| Sūtra retriever | |
| Example retriever | |
| LLM explainer |
7.2 Pure Hindi Generation
Pure Hindi generation is not merely “translate into Hindi.” It needs:
- Sanskritic vocabulary preference
- removal/avoidance of Urdu/Persian/Arabic loanwords where desired
- controlled register: not too difficult, not vulgarized
- technical English retained where useful
- custom lexical filter
- training samples from accepted style
Best method: train a style adapter or SFT dataset for pure Hindi, then add a post-generation lexical checker.
Do not rely only on prompting.
Pipeline:
- generate draft
- scan for banned/undesired loanwords
- replace with preferred Sanskritic alternatives
- check readability
- optionally regenerate sentence by sentence
- final human review
8. RAG for Sanskrit, Purāṇas, MBFR, and Research
8.1 Why RAG Is Essential
Fine-tuning should not be used as a dumping ground for all knowledge. A model should not be expected to memorize entire Purāṇas, MBFR pages, commentaries, and research notes.
Correct approach:
- use RAG for factual recall
- use LLM for reasoning and synthesis
- use fine-tuning for style, behavior, and task discipline
8.2 Sanskrit/Purāṇa RAG
Corpus pipeline:
- collect Devanagari texts
- normalize encoding
- remove page noise, headers, footnotes where needed
- preserve references such as chapter/verse markers
- split by verse, passage, or semantic unit
- create metadata: text, section, source, topic, deity, speaker, meter if available
- embed passages
- add keyword index
- add reranker
- generate answer only from retrieved passages
8.3 MBFR RAG
For MBFR:
- keep HTML/Markdown/Wikidot sources clean
- chunk by heading and subheading
- preserve equations and assumptions
- index design scenarios separately
- include safety/governance passages
- retrieve relevant technical and policy sections together
The LLM should answer:
- what the design claims
- what assumptions are used
- what calculations support it
- what risks remain
- what governance safeguards are required
9. Numeric Prediction: Gold, Rainfall, Weather, etc.
9.1 LLM Is Not the Predictor
For gold, rainfall, weather, earthquake indicators, and similar numeric outputs, the main model should be MLP or another tabular/time-series model, not Grok-2 and not a general LLM.
The old house-price analogy is correct:
- many input parameters
- one or more numeric outputs
- output indicates magnitude, probability, or strength
Examples:
| Domain | Inputs | Output |
|---|---|---|
| Gold price | macroeconomic, market, astrological, time-cycle, historical data | price change / strength score |
| Rainfall | date, location, season, pressure, humidity, chart factors, historical rainfall | rainfall magnitude |
| Weather severity | observed + computed features | severity score |
| Earthquake risk research | geological + temporal + celestial indicators where tested | probability/strength score |
9.2 Recommended ML Models
Use these in order:
- baseline linear/logistic regression
- Random Forest / Gradient Boosting
- XGBoost / LightGBM / CatBoost
- MLP
- LSTM/Transformer only if sequence structure justifies it
Do not start with a giant model. Start with measurable baselines.
9.3 Correct LLM Role in Forecasting
The LLM can:
- explain the numeric output
- generate reports
- compare today with prior similar cases
- retrieve historical examples
- write code
- summarize feature importance
- produce pure-Hindi public explanation
The LLM must not secretly override the MLP output.
9.4 Forecast Output Format
Use structured output:
{
"model": "gold_mlp_v03",
"date": "YYYY-MM-DD",
"input_window": "last_60_days",
"prediction": {
"direction": "up",
"strength": 0.72,
"expected_range_percent": [1.2, 2.8]
},
"confidence": 0.64,
"top_features": [
"feature_1",
"feature_2",
"feature_3"
],
"warning": "Not financial advice; model under validation."
}Then the LLM may convert this into a human explanation.
10. Adapter Strategy
10.1 Use Separate Adapters
Do not mix unrelated tasks in one adapter.
Recommended adapters:
| Adapter | Purpose |
|---|---|
| hindi_style_lora | pure Hindi / Sanskritized Hindi writing |
| mbfr_assistant_lora | MBFR explanation style and terminology |
| jyotisha_explainer_lora | |
| sanskrit_grammar_lora | |
| code_vb6_cpp_lora | |
| geopolitical_synthesis_lora | |
| wikidot_writer_lora |
10.2 Do Not Merge Too Early
Separate adapters should remain separate unless:
- their tasks are compatible
- benchmark shows no degradation
- the merged adapter is tested against all original tasks
Adapter conflict is real. A pure-Hindi adapter and a code adapter may not cooperate well. A Jyotiṣa adapter and MBFR adapter should not be merged unless needed.
10.3 Router-Based Loading
A small router should select the model/adapters:
User request
|
+-- Numeric forecast? ------> MLP / tabular model -> LLM explanation
|
+-- Jyotiṣa calculation? ---> VB6/C++ engine -> rule engine -> LLM explanation
|
+-- Sanskrit passage? ------> RAG + grammar tools -> LLM synthesis
|
+-- MBFR question? ---------> MBFR RAG -> LLM synthesis
|
+-- Code request? ----------> coding model / code adapter
|
+-- Pure Hindi essay? ------> Hindi style adapter + lexical filter
|
+-- General reasoning? -----> 30B–34B instruct model or Grok-2 if useful11. Training Dataset Design
11.1 General Instruction Dataset
Format:
{
"instruction": "Explain the following Jyotiṣa rule output in clear technical language.",
"input": {
"computed_factors": "...",
"rules_applied": "...",
"conflicts": "..."
},
"output": "..."
}11.2 Pure Hindi Dataset
Each sample should include:
- English/Hindi source
- desired pure Hindi output
- banned words if any
- preferred alternatives
- style level: simple, medium, scholarly
- technical English terms allowed
Example:
{
"instruction": "Rewrite in simple pure Hindi, avoiding Urdu/Persian/Arabic vocabulary.",
"input": "The financial system exploits developing countries through dollar dominance.",
"output": "वित्तीय तन्त्र डॉलर-प्रधान व्यवस्था द्वारा विकासशील देशों का आर्थिक शोषण करता है।",
"constraints": {
"avoid": ["system as सिस्टम if तन्त्र works", "तरीका", "जरिया"],
"allow_english_terms": ["dollar", "financial"]
}
}11.3 Jyotiṣa Explanation Dataset
The model should not calculate. It should explain supplied calculations.
{
"instruction": "Explain this computed Jyotiṣa result without inventing missing facts.",
"input": {
"lagna": "...",
"varga_data": "...",
"dasha": "...",
"rules": [
{"rule_id": "R001", "text": "...", "score": 0.72}
]
},
"output": {
"summary": "...",
"supporting_factors": ["..."],
"opposing_factors": ["..."],
"final_synthesis": "...",
"confidence": "medium"
}
}11.4 MBFR Dataset
Use:
- question
- retrieved MBFR passages
- calculation assumptions
- answer
- uncertainty
- safety note
The model must distinguish between:
- demonstrated fact
- engineering assumption
- proposed design
- policy recommendation
- speculation

14. Deployment Architecture
14.1 Local Server Plan
Run services separately:
| Service | Machine |
|---|---|
| Main LLM server | Z890 |
| Embedding server | |
| RAG/vector DB | |
| MLP forecast API | |
| VB6/C++ astrology engine | |
| Web UI / router | |
| Laptop access |
14.2 Simple Router
The router receives a user query and calls the right backend.
Pseudo-logic:
def route_request(query): if is_numeric_forecast(query): result = call_mlp_forecast(query) return explain_with_llm(result) if is_jyotisha_calculation(query): chart = call_astrology_engine(query) rules = apply_jyotisha_rules(chart) passages = retrieve_classical_sources(rules) return explain_jyotisha(chart, rules, passages) if is_sanskrit_or_purana_query(query): passages = retrieve_sanskrit_corpus(query) return answer_from_passages(query, passages) if is_mbfr_query(query): passages = retrieve_mbfr_docs(query) return answer_mbfr(query, passages) if needs_pure_hindi(query): draft = call_hindi_adapter(query) return lexical_filter(draft) if is_code_query(query): return call_code_model(query) return call_general_llm(query)
15. Practical Priority Order
15.1 Phase 1: Stabilize Local Inference
- Test 7B–14B model on Omen17
- Test 24B–34B model on RTX 3090
- Test 30B–34B model on dual RTX 5090
- Benchmark Grok-2 298GB only after the above are stable
15.2 Phase 2: Build RAG
- Sanskrit corpus RAG
- MBFR RAG
- Jyotiṣa rule RAG
- code/documentation RAG
- pure-Hindi lexical database
15.3 Phase 3: Build Dataset
- instruction samples
- rejected bad-output samples
- pure-Hindi rewrites
- MBFR Q&A
- Jyotiṣa explanation samples
- Sanskrit grammar explanation samples
- code conversion samples
15.4 Phase 4: Train Adapters
- Hindi style adapter
- MBFR adapter
- Jyotiṣa explanation adapter
- Sanskrit grammar adapter
- code adapter
15.5 Phase 5: Numeric ML
- gold model
- rainfall model
- weather model
- other strength-output models
- connect their outputs to LLM explanation
15.6 Phase 6: Grok-2 Integration
Only after the system works:
- benchmark Grok-2 local speed
- compare Grok-2 with 30B–34B models
- use Grok-2 for batch reasoning if useful
- avoid making Grok-2 a dependency for daily work unless speed is acceptable
16. Final Working Principle
The best system is not one giant LLM.
The best system is:
- deterministic engines where rules must be exact
- MLP/tabular models where output is numeric
- RAG where knowledge must be cited and retrieved
- 30B–34B local LLMs where reasoning and language are needed
- Grok-2 as a large experimental model if it proves useful on my hardware
- small models for routing, testing, and laptop work
- human review for final intellectual responsibility
Therefore:
- Use Z890 dual RTX 5090 as the main AI laboratory.
- Use Z490 RTX 3090 as the stable inference/RAG/embedding server.
- Use Omen17 RTX 3070 Ti as the portable controller and test machine.
- Keep Grok-2 298 GB as a valuable local asset, but do not make the whole architecture depend on it until benchmarked.
- For Jyotiṣa and Sanskrit, use rule-first architecture.
- For gold/weather/rainfall, use MLP/tabular prediction first.
- For essays, explanations, pure Hindi, and synthesis, use LLM + RAG + filters.
17. Alternatives: Other Large Downloadable Models for Mostly-Frozen Partial Fine-Tuning
Purpose of this section:
This section lists large downloadable full-weight or open-weight models, comparable in spirit to my local Grok-2 experiment, which may be suitable for mostly-frozen partial fine-tuning through PEFT, LoRA, QLoRA, adapter training, or similar methods.
This section is not about small 7B, 14B, or 30B models. It is about large models whose base weights can be kept mostly frozen while a small project-specific adapter is trained.
17.1 Main Principle
The purpose is not to fully fine-tune these huge models. Full fine-tuning of such models is generally impractical on my local hardware.
The practical method is:
- download the model weights if license and storage permit
- load the model in the lightest working quantized/offloaded backend
- keep the base weights frozen
- train only a small LoRA/PEFT adapter
- save adapter weights separately
- compare base-model output and adapter-enhanced output
- never merge the adapter into the base model until extensive testing is complete
Important MoE warning:
For Mixture-of-Experts models, the number of active parameters reduces compute per token, but the model still has a much larger total weight bank. Therefore, a model with 22B or 32B active parameters may still require handling 235B, 355B, 671B, or even 1T total parameters through VRAM, RAM, NVMe offload, or expert-loading methods.
17.2 Hardware Assumption
The evaluation here is based on my actual machines:
| Machine | Role |
|---|---|
| Z890-AI Top + dual RTX 5090 + 256 GB RAM | main machine for large-model inference, quantization, offloading, and small adapter experiments |
| Z490 + RTX 3090 + 128 GB RAM | support machine for dataset preparation, embeddings, RAG, smaller inference, evaluation |
| Omen17 + RTX 3070 Ti 8 GB + 64 GB RAM | portable controller, dataset editing, testing, remote operation |
The Z890 dual RTX 5090 has 64 GB total VRAM, not 80 GB, not 96 GB. Therefore, any model designed for a single 80 GB H100-class GPU may still need quantization, CPU offload, NVMe offload, tensor parallelism, or a specialized backend on my system.
17.3 Practical Ranking for My Mostly-Frozen Adapter Experiments
The ranking below is not only by raw intelligence or benchmark fame. It is ranked by usefulness for my local partial fine-tuning experiments.
| Rank | Model | Type | Approx. Scale | Practical Judgment |
|---|---|---|---|---|
| 1 | OpenAI gpt-oss-120b | MoE | 117B total / 5.1B active | Best first non-Grok large PEFT target; large but comparatively practical |
| 2 | Qwen3-235B-A22B | MoE | 235B total / 22B active | Best balance of size, quality, context, and practicality |
| 3 | GLM-4.5 | MoE | 355B total / 32B active | Serious agentic/coding/reasoning model; heavier but attractive |
| 4 | Llama 4 Maverick | MoE, multimodal | approx. 400B total / 17B active | Strong Meta model; useful but license/tooling complexity matters |
| 5 | DeepSeek-V3 / R1 family | MoE | 671B total / 37B active | Excellent reasoning/coding, but heavy for local PEFT |
| 6 | Mistral Large 3 | MoE, multimodal | 675B total / 41B active | Excellent Apache-2.0 European open-weight option; very heavy |
| 7 | Kimi K2 | MoE | 1T total / 32B active | Very strong agentic/coding model; too heavy for first PEFT attempt |
| 8 | GLM-5 / GLM-5.1 class | MoE | around 744B–754B class / ~40B active | Frontier-scale, but likely a large infrastructure project |
| 9 | Tencent Hunyuan-Large | MoE | 389B total / 52B active | Technically relevant and PEFT-friendly, but less attractive than newer models |
| 10 | Mistral Large 2 / 123B | Dense | 123B dense | Strong dense baseline, but dense memory load is less convenient than MoE |
Best practical sequence after Grok-2:
First test gpt-oss-120b, then Qwen3-235B-A22B, then GLM-4.5.
Only after these are stable should I attempt DeepSeek, Mistral Large 3, Kimi K2, GLM-5 class, or other 600B–1T models.

17.14 Best Adapter Projects for These Large Models
For all of these huge models, the first adapter project should be linguistic, structural, or explanatory. It should not be numeric prediction.
Best first adapter projects:
| Priority | Adapter Project | Why It Is Suitable |
|---|---|---|
| 1 | Pure Hindi + Wikidot formatting | easy to evaluate, useful immediately, low risk |
| 2 | MBFR technical explanation | controlled terminology and style, useful for website/policy pages |
| 3 | Sanskrit/Purāṇa RAG answer formatting | model explains retrieved passages without needing to memorize corpus |
| 4 | Jyotiṣa explanation-only adapter | explains computed outputs but does not calculate or predict independently |
| 5 | VB6/C++ code assistant style | useful for my actual codebase and DLL/VB6 workflows |
Do not start with: gold price prediction, rainfall prediction, weather magnitude prediction, or deterministic Jyotiṣa phala generation.
Those should remain under MLP/tabular models, classical rule engines, and computed feature pipelines. The LLM should explain the result, not secretly generate the result.
17.15 Practical Testing Order
Recommended testing sequence:
- Grok-2 local copy: one small mostly-frozen adapter experiment
- gpt-oss-120b: first alternative large PEFT experiment
- Qwen3-235B-A22B: best balance large MoE
- GLM-4.5: serious agentic/coding/reasoning model
- Llama 4 Maverick: Meta ecosystem comparison
- DeepSeek-V3 / R1: high-reasoning heavy model
- Mistral Large 3: high-quality Apache-2.0 frontier-scale model
- Kimi K2: 1T-scale agentic model, later only
- GLM-5 / GLM-5.1 class: later infrastructure experiment
- Tencent Hunyuan-Large or Mistral Large 2: special-purpose comparison
This sequence avoids wasting time by jumping directly into 600B–1T models before the adapter pipeline is proven.
17.16 Evaluation Checklist for Any Alternative Large Model
Before training an adapter, record:
| Test Item | What to Record |
|---|---|
| folder size | total GB after download |
| file format | safetensors, GGUF, FP8, MXFP4, NVFP4, etc. |
| tokenizer | tokenizer type and chat template |
| backend | Transformers, vLLM, SGLang, llama.cpp, KTransformers, etc. |
| license | whether commercial use, redistribution, derivative adapters are allowed |
| context length | tested context length, not only advertised length |
| VRAM use | one 5090, two 5090s, RTX 3090 if tested |
| RAM use | system RAM at load and during inference |
| disk activity | whether HDD/NVMe is being hammered |
| tokens/sec | prompt processing and generation speed |
| output quality | |
| adapter effect | |
| failure modes | hallucination, formatting break, Hindi impurity, code errors, etc. |
No model should be accepted merely because it is famous or huge.
17.17 Final Recommendation
My practical large-model path:
- Use my local Grok-2 copy first for one mostly-frozen adapter test.
- Then test gpt-oss-120b as the most practical alternative large model.
- Then test Qwen3-235B-A22B as the best balance of scale and usability.
- Then test GLM-4.5 for agentic coding and reasoning.
- Treat DeepSeek, Mistral Large 3, Kimi K2, and GLM-5 class models as later high-end experiments.
- Keep numeric forecasting and deterministic Jyotiṣa calculation outside the LLM.
- Use LLM adapters for explanation, style, formatting, synthesis, and controlled domain language.
