Connector
A controlled remote invocation channel that wraps the capabilities of external services into interfaces callable by a model, enabling the model to read data and perform operations without requiring users to manage credentials manually.
Timeline (last 90 days)
In connector-based speech LLMs, a trainable connector maps speech representations into a frozen LLM, and the LLM itself does not need fine-tuning.
Target-only fine-tuning of just the connector lets the model learn the new language but causes severe degradation in source-language performance (catastrophic forgetting).
In Claude Code, every enabled MCP server or connector carries its tool definitions (name, description, parameter schema) in every message, and these definitions consume tokens.
A Connector is a link that allows a model to directly read real-time data from external applications, and both Claude Cowork and Gemini Spark have this functionality built in.
