CODEX GAINS SMARTER BUFFERING SIGNALS IN LATEST ALPHA

Codex now reads faster-model metadata directly from streamed payloads, letting you build buffering UI that actually knows when the model is warming up.

The latest alpha release [1] ships a cleaner buffering contract: instead of relying on response headers alone, the buffering payload itself now carries optional faster-model metadata that takes precedence when present [1]. This means your UI can make better decisions about when to show loading states without parsing header values. The implementation retains backward compatibility by falling back to existing response metadata when the payload omits the field, so existing integrations won't break [1]. The change surfaces real model state in the event stream itself, giving you finer-grained control over the user experience during model inference. Version 0.143.0-alpha.36 [2] ships with this improvement baked in.
