Mistral AI secures US patent for 'code implemented tool calls'
TL;DR. Mistral AI received a US patent for "Code implemented tool calls" in just 118 days, bypassing public objection windows. - The patent describes a stateless sandbox that pauses code execution, sends a single tool call to a client, and resumes by replaying the block. - The claims are narrowly focused on a specific engineering choice for handling tool calls, distinct from broader agent code generation. - This rapid grant process highlights a potential issue with the US patent system's prior art review for fast-moving AI innovations.
