AgentLens – replay and compare Codex agent runs
AgentLens is a tool that replays AI coding agent sessions, showing what Codex likely read, ran, and changed, and lets users compare two runs to find where they diverged. It targets developers debugging or evaluating agent behavior. Codex runs are the LLM-driven workflows being reconstructed.

AI coding agents gain ability to tune algorithms via experiments
A new capability enables AI coding agents like Claude Code, Codex, and OpenCode to run experiments, learn from results, and autonomously decide which parameters to try next, effectively tuning algorithms without human intervention. This development could significantly reduce the manual effort required for hyperparameter optimization and algorithm refinement.

Claude Code Workflows for GPT/Codex
A tool that brings Claude Code's workflow capabilities to GPT and Codex models, allowing users to define and execute multi-step coding tasks with LLMs. It solves the problem of limited workflow support in GPT-based coding assistants, targeting developers who want structured, repeatable AI-assisted coding processes.
