Automating Fork Maintenance With AI Agents
Cohere, Thursday, June 25th, 2026
Cohere applies control-theory principles and AI coding agents to automate keeping software forks in sync with upstream.
Cohere describes an automated method for maintaining software forks using AI coding agents. The approach applies closed-loop control theory to the workflow, automating the repetitive cycle of syncing upstream releases, measuring functionality, and fixing issues.
At Cohere the technique compressed vLLM fork updates from weeks to days, with human review limited to final outcomes.
The post walks through a real example where an agent detected and resolved a breaking change in the Cohere Transcribe model caused by an upstream library update, then contributed the fix back to vLLM as an upstream pull request.
