Self-supervised learning for language models to use external tools

Core Idea:

Toolformer is a language model capable of using external tools via simple APIs, trained in a self-supervised manner with minimal demonstrations to autonomously determine when and how to utilize tools to enhance its capabilities.

Key Principles:

1. API Integration:
   • Using external tools through standardized API calls
2. Self-Supervised Learning:
   • Training the model to recognize when tool use would improve predictions
3. Utility-Based Selection:
   • Filtering API calls based on whether they help predict future tokens

Why It Matters:

• Extended Capabilities:
  • Overcomes model limitations in areas like math, factual knowledge, and time awareness
• Reduced Hallucination:
  • Provides grounding through external verification
• Augmented Intelligence:
  • Combines model reasoning with specialized tool capabilities

How to Implement:

1. Annotate API Calls:
   • Prompt a pre-trained model to annotate datasets with potential API calls
2. Filter Helpful Calls:
   • Keep only API calls that improve prediction of future tokens
3. Fine-tune Model:
   • Train on the combined dataset of original and API-annotated sequences

Example:

• Scenario:
  • Mathematical calculation beyond model precision
• Application:
  • Text: "What is 1728 multiplied by 143.5? Let me calculate this. [CALCULATOR(1728*143.5)]"
  • API response: "248016.0"
  • Completion: "The answer is 248,016."
• Result:
  • Accurate calculation using external calculator tool without hallucination
