OpenAI Codex CLI Adds Voice Chat and Multi-Agent View

KEY FACTS

OpenAI announced a Codex CLI upgrade at its DevDay 2026 event.
Codex CLI adds voice chat, letting users launch and steer tasks by voice.
The new version offers an /agents view that supports assigning work to multiple agents and tracking progress.
The update improves prompt editing and session resumption, and adds built-in worktree support.
The terminal interface is updated too, making long sessions easier to read, and the update covers all plans.

PHYSIX OBSERVATION

With voice plus multiple agents, Codex CLI is turning from a command-line tool into a commandable coding workbench. For developers, the entry point is more natural and parallel tasks are handier, but the reliability and cost of multi-agent collaboration remain open questions. By pushing the capabilities down to all plans, OpenAI aims to grab territory and build usage habits.
