Mistral Patent for "Code implemented tool calls"

Mistral Patents Sandboxed Code for Tool Calls

Mistral AI has been granted a patent for a method that uses a large language model to generate code blocks encapsulating tool calls, which are then executed in a sandbox. When a pending tool call is reached, execution pauses, the call is sent to a client, and the result is substituted before resuming. The final result is returned to the LLM, enabling more reliable and secure tool use.
