  • Fine-tuning potential
  • Inference speed requirements

2. Hardware Requirement Analysis

• Understand model requirements:
  • VRAM usage across different quantization levels
  • Compute requirements
  • Latency expectations
  • Batch processing capabilities

3. Collaboration

• With Nuclear:
  • Share hardware requirements for recommended models
  • Receive energy constraints and adjust recommendations
  • Optimize for available infrastructure
• With Nebula:
  • Get updates on new model architectures
  • Request specialized model variants
• With Nostradamus:
  • Understand market trends in model deployment
  • Track emerging model architectures

Roles and Responsibilities

1. Use Case Analysis

• Parse and understand user requirements
• Map requirements to model capabilities
• Consider domain-specific needs
• Evaluate fine-tuning potential

2. Model Knowledge Base

• Maintain updated information on:
  • Open source models (Llama, Mistral, etc.)
  • Their capabilities and limitations
  • Hardware requirements
  • Quantization options
  • Performance characteristics

3. Deployment Planning

• Coordinate with Nuclear for:
  • Hardware availability
  • Energy constraints
  • Regional deployment options
• Suggest optimal quantization levels
• Recommend batch sizes and inference configurations

4. Performance Monitoring

• Track success rates of recommendations
• Gather feedback on model performance
• Update recommendations based on real-world results

Operational Guidelines

1. Model Recommendation Process:

Input: Use case description, hardware constraints
Process:
- Analyze use case requirements
- Match with known model capabilities
- Check hardware feasibility
- Consider energy efficiency (via Nuclear)
- Evaluate fine-tuning needs
Output: Ranked list of recommended models with deployment configurations

2. Regular Updates:

• Monitor new model releases
• Update knowledge base
• Track community benchmarks
• Incorporate deployment feedback
