# OpenAI updates Codex CLI with voice and parallel agent workflows

The update adds bidirectional voice interaction, session forking into managed worktrees, and tools to monitor parallel agent tasks inside the terminal.

- Supports two-way voice interaction directly in the terminal via the /voice command
- Adds /fork to branch conversations into isolated Git worktrees with shared context
- Introduces /agents to track and switch between concurrent background tasks
- Renders Mermaid diagrams and LaTeX natively alongside collapsible diffs and tool outputs
- Available by updating through npm with @openai/codex@latest

## Why it matters

Terminal-based developers can now manage multi-agent coding sessions and interact via voice without leaving the command line.
