What changed in AI tools — September 2026
A public keep/cut digest of recorded vendor launches and directory checks this month. OpenAI released GPT-6 Astra on 2026-09-03: official Path to Astra post designates it at Critical cybersecurity capability, with advanced cyber access gated to trusted testers / Daybreak Blue; Axios reports limited Daybreak Access first, then ChatGPT Plus / Pro / Business / Enterprise and API in the coming days — not a new SKU and not a confirmed Plus/Pro price change. Perplexity open-sourced Lily (2026-09-02 official blog) as a lightweight local inference engine for Apple silicon and Qwen3.6-35B-A3B, tied to Perplexity Computer hybrid compute — not a new paid SKU. Catch (catchagent.ai) was listed on 2026-09-02 after the official homepage and /security page advertised $99/month billed monthly (cancel anytime, 10-day free trial); /pricing 404s and the same homepage still shows Closed Beta — Limited Spots.
