Optimal Small AI Training

Hypothesis

Can small local AI models be effectively trained for lookup scripts and specialized tasks, overcoming inherent limitations in context and reasoning?

Approach

1. Analyzed limitations of small AI models (context, reasoning, knowledge fragility)
2. Researched RA-FT (Retrieval-Augmented Fine-Tuning) methodology
3. Evaluated curriculum training approaches
4. Designed skill injection strategies for local AI

Findings

Key Observations

Limitations of Small Models:

Limitation	Impact	Mitigation
Context limits	Cannot process large codebases	Chunking, RAG
Reasoning limits	Struggles with multi-step logic	Task decomposition
Knowledge fragility	Forgets under distribution shift	Curriculum training
Hallucination	Confident wrong answers	Uncertainty calibration

RA-FT (Retrieval-Augmented Fine-Tuning):

Combines retrieval systems with fine-tuning:

1. Retrieval Phase: Find relevant context from knowledge base
2. Augmentation Phase: Inject retrieved context into prompt
3. Fine-Tuning Phase: Train model on task with augmented context

Benefits:

• Reduces hallucination by grounding in retrieved facts
• Extends effective knowledge without model size increase
• Allows domain-specific specialization

Curriculum Training:

Progressive skill building:

Level 1: Basic lookup (key → value)
    ↓
Level 2: Multi-step lookup (key → intermediate → value)
    ↓
Level 3: Reasoning over lookups (key → reasoning → conclusion)
    ↓
Level 4: Self-correction (detect error → retry → validate)

Skill Injection Strategies:

1. Narrow Scope: Train for specific task, not general intelligence
2. Ground Truth Anchoring: Always provide reference data
3. Uncertainty Expression: Train to say “I don’t know”
4. Verification Loops: Output must be validated before use

Practical Implementation

For local AI (Jan/Llama-based):

1. Curate high-quality task-specific dataset
2. Fine-tune on retrieval-augmented examples
3. Implement verification step in pipeline
4. Use larger model as “teacher” for curriculum

Outcome

Status: Partial

Methodology established. Requires implementation with local AI stack.

Next Steps

• Create curated dataset for first skill domain
• Set up Jan/Llama fine-tuning pipeline
• Implement RAG retrieval layer
• Design verification loop for outputs
