Zero-shot Learning
Industry Definition Set • Entity Resolution Path: /glossary/zero-shot-learning
Quick Answer / TL;DR
An LLM capability where the model performs a task without any task-specific examples, relying only on the instruction in the prompt.
Key Takeaways
- Model performs tasks without examples in the prompt.
- Relies on pre-training knowledge.
- Default mode for most LLM interactions.
- Works best with clear tool schemas and descriptions.
Definitive Statement: An LLM capability where the model performs a task without any task-specific examples, relying only on the instruction in the prompt.
Technical Context & Protocol Usage
- Detailed Explanation
- Zero-shot learning is the default mode for most LLM interactions. The model relies on its pre-training to understand the task from a natural language instruction alone. In MCP, zero-shot tool selection means the model must infer how to use a tool from its schema and description alone, without additional examples in the prompt.
Format & Payload Metadata
Format: Prompt with instruction only, no examples
Latency: No overhead; uses context window tokens
Real-World Implementation Use Case
An agent uses a `weather_lookup` tool with zero-shot learning, inferring from the tool description that it should provide a city name.
