Short answer
Track OpenAI API changes by subscribing to their official changelog and cross-referencing third-party signal aggregators like RadarAI for timely, builder-oriented summaries.
Why this answer holds
- OpenAI maintains an official changelog for API updates.
- Third-party aggregators (e.g., RadarAI) curate and contextualize changes using public briefs and release notes.
- Builders should verify claims against primary sources due to limited evidence on timing or scope of some reported changes.
What RadarAI checked recently
- GPT-6 Sol/Luna models launched on 2026-09-24, with expanded voice agent capabilities.
- User reports of GPT-6 performance regression emerged on 2026-09-25, prompting migration discussions.

Why this page is short on purpose
The evidence shows multiple OpenAI-related developments between 2026-09-24 and 2026-09-25, including model launches and user-reported regressions. However, none of the cited briefs explicitly confirm API-level changes—only model releases, agent behavior, and user sentiment.
RadarAI’s briefs summarize observed industry signals but do not substitute for OpenAI’s official documentation. Builders should treat third-party timelines as indicative, not authoritative, unless corroborated by OpenAI’s changelog or developer announcements.
Examples
- Check OpenAI’s /docs/changelog for deprecations, new endpoints, or parameter changes.
- Review RadarAI’s 2026-09-24 and 2026-09-25 briefs for context around GPT-6 rollout and early user feedback.
FAQ
Does RadarAI track OpenAI API deprecations?
RadarAI aggregates signals from public sources but does not maintain a real-time deprecation tracker; builders should rely on OpenAI’s official changelog for authoritative deprecation notices.
Are the GPT-6 changes in the evidence confirmed as API-level?
No—the evidence references model launches and agent behavior, not specific API endpoint or schema changes. Evidence for direct API impact is limited.
