New Capabilities

Codex CLI 0.115.0 adds several significant developer-facing features for image processing, real-time interactions, and filesystem operations.

Image Inspection Enhancements

Supported models can now request full-resolution image inspection through both the view_image method and codex.emitImage(..., detail: "original"). This enhancement enables greater precision for visual analysis tasks where detail matters.

JavaScript REPL Improvements

The js_repl environment now exposes codex.cwd and codex.homeDir for better filesystem context, and saved references to codex.tool(...) and codex.emitImage(...) persist across cells. This improves the developer experience when building multi-step automation sequences.

Realtime Transcription and Handoff

Realtime websocket sessions now include a dedicated transcription mode and v2 handoff support through the codex tool, accessed via a unified [realtime] session configuration. This streamlines voice and streaming interaction workflows.

App Server Filesystem Integration

The v2 app-server now exposes filesystem RPC operations including file reads, writes, copies, and directory operations with path watching capabilities. A new Python SDK provides programmatic integration with these filesystem APIs, making it easier to build automation tools.

Installation
