Codex CLI 0.155.0 adds voice conversations and Touch ID for MCP
Speak to your coding agent, watch its reasoning live, gate MCP calls behind a fingerprint, and clear out runaway agent worktrees.

Talk to Codex in your terminal
Codex CLI 0.155.0 adds experimental `/voice` conversations — live transcripts, microphone controls, and a mute shortcut, turned on behind `/experimental`. You can now dictate to your coding agent hands-free instead of typing every prompt.
Watch the model reason, live
The terminal UI now shows live reasoning summaries in the status row and stamps each turn with a completion time. Less staring at a blank spinner wondering whether the agent is stuck or actually thinking.
Touch ID now gates your MCP calls
On supported Macs, MCP tool requests in local TUI sessions can require Touch ID verification. A fingerprint check before an external tool touches your machine is a real guardrail if you run MCP servers you don't fully trust.
Clear out runaway agents and worktrees
The agents overview gains task hiding, archiving, and deletion, plus worktree ownership details and confirmed removal of clean managed worktrees; daemons now recover saved threads and goals after a restart. Amazon Bedrock users can also pull AWS credentials from configured commands, with caching and expiry-based refresh.
Elsewhere: GLM says GLM built the stack that serves it
Z.ai detailed how its GLM-5.3 model acted as an 'infra agent' to build and optimize the inference stack now serving GLM-5.3-Flash on 100,000+ Chinese-made chips — production-ready in under two weeks, with end-to-end throughput roughly tripling the initial baseline.
Elsewhere: LLMs that rewrite their own weights mid-session
A new arXiv paper, 'Infinite-Parameter LLMs,' proposes generating and adapting weights from live data via a compact hypernetwork, so runtime knowledge lives in weights instead of eating your context window. It's an architecture and evaluation protocol, not a release — but a direction worth tracking.
