Short answer
Track OpenAI API changes by subscribing to OpenAI's official changelog and monitoring trusted technical briefings that cite specific versioned updates.
Why this answer holds
- OpenAI publishes API changes in its official changelog.
- Third-party briefings (e.g., RadarAI) summarize observed shifts but do not replace official documentation.
- Builder decisions depend on verifying changes against production behavior—not just announcements.
What RadarAI checked recently
- GPT-5.6 entered controlled rollout with customer-specific approval gates (June 26, 2026).
- Codex now handles over 90% of OpenAI’s internal coding; new Record & Replay and Artifact features launched June 26, 2026.

Primary sources / verification path
Why this page is short on purpose
The evidence shows recurring references to Codex adoption and GPT-5.6’s phased release—but no direct citations of OpenAI API endpoint deprecations, parameter changes, or rate-limit adjustments.
All cited updates come from RadarAI briefings, which summarize trends and internal usage shifts; none reference specific API version numbers, breaking changes, or schema modifications. Builders should treat these as contextual signals—not API change notifications.
Examples
- Check OpenAI’s /changelog endpoint daily for versioned release notes.
- Cross-reference RadarAI briefings (e.g., Issue #421, June 26) with OpenAI’s official docs before updating client integrations.
FAQ
Does RadarAI track OpenAI API deprecations?
No—RadarAI briefings highlight usage trends and product milestones, not API contract changes. Builders must rely on OpenAI’s official changelog for deprecation notices.
Is GPT-5.6 available via public API?
Evidence confirms only a controlled rollout with customer-specific approval; no public availability or API access details are cited.
