OpenAI appears to be preparing a new personalization layer for Codex called Avatars, a system that would let users pick a visual companion from their settings menu and have it appear as an on-screen overlay during coding sessions. Once selected, the avatar would surface replies through speech-bubble style messages, adding a character-driven presence to what has otherwise been a fairly utilitarian developer tool. The feature is toggleable, so users who prefer a cleaner workspace can switch it off entirely without losing any underlying Codex functionality.
The new Codex avatars coming soon are fun.

Eight predefined avatars are expected to ship at launch, rendered in a pixel-art style that leans deliberately cute rather than corporate. More notably, users will also be able to design their own custom avatars, giving the feature a creative dimension that goes beyond simple cosmetic presets. The direction fits a broader pattern across OpenAI's consumer surfaces, where personality and identity cues are becoming a recurring theme, echoing moves like ChatGPT's voice personas and the personalization options that have been quietly expanding across the product line.

this is real, and it's in the Codex app.
it's not a third party avatar overlay.

The arrival of Avatars also follows closely on the heels of Chronicle, a feature OpenAI recently rolled out in Codex that captures screenshots of in-progress work and feeds them to a background agent to generate memories from that visual context. OpenAI is flagging meaningful caveats around Chronicle, including higher token consumption and a greater exposure to prompt injection risks, which is why the rollout has been kept deliberately narrow. Chronicle is currently limited to Pro users in a Research Preview, excludes people in the EU and UK, and runs only on macOS for now.
Chronicle feature will become available in Personalization settings on Codex and will require screen capture permission.

Taken together, Avatars and Chronicle point to a Codex that is evolving from a pure coding assistant into something closer to a persistent, personality-bearing desktop companion, a repositioning that tracks with how rivals like Anthropic, xAI, and Google are reframing their own agentic coding tools. An official unveiling for Avatars has not yet surfaced, but the groundwork inside the product suggests it should not be far off.
