OpenAI Agents API ships Auto Review, async compaction, experimental time awareness and mid-session tool updates
The OpenAI Developers account shared a post by Steve (@stevendcoffey), who works on the API at OpenAI, listing five Agents API updates this week: Codex-style Auto Review of commands before execution, compaction that runs in the background, an experimental time-awareness feature, updating a session's tools at any time, and automatic caching of system prompts across all sessions. As of writing, the official API changelog does not list these items yet.
Key Takeaways
- Five updates: Auto Review, async compaction, time awareness (experimental), updating session tools at any time, and automatic cross-session system prompt caching
- Auto Review mirrors the Codex mechanism and evaluates commands for potential bad behavior before they run
- Time awareness lets the model act on time-boxed instructions such as "timebox CI fixes to 10 minutes"
- The Agents API entered public beta on September 10, and this is another round of features within 7 weeks (after computer use on Sep 29, sandbox prewarming on Oct 9 and Ultrafast mode on Oct 16)
- OpenAI has published no latency or cost-saving numbers, and the changelog has not listed these items yet
