GPT-6 Astra in 30 Seconds GPT-6 Astra is OpenAI’s new flagship, announced on September 3, 2026. The company calls it “the world’s most intelligent and aligned model”. There is no Sol/Terra/Luna split this time. The lineup is Astra and Astra Pro. API pricing is $10 per million input tokens and $50 per million output tokens: 2.5x GPT-5.6 Sol’s promotional price, and identical to Claude Fable 5.1. The scores are high but footnoted. The headline 98.6% on ARC-AGI-3 came from a custom harness; the same model scores 62.7% on the standard one. Astra is the first OpenAI model to cross the Critical cybersecurity threshold in the Preparedness Framework. Standard access refuses parts of that work outright. Rollout is staged: Daybreak enterprise customers first, then Plus, Pro, Business, Enterprise, the API and AWS. Pro, Business and Enterprise also get Astra Pro. OpenAI launched GPT-6 Astra today, September 3, 2026. At the press briefing, president Greg Brockman first conceded that AGI remains a “gray, fuzzy thing”, then went ahead anyway: “I think it’s not unreasonable to feel that we are now in the AGI era.” He closed with the same line: “Welcome to the AGI era.” ...

Summary: GPT-5.6-Cyber in 30 Seconds GPT-5.6-Cyber is a version of GPT-5.6 Sol trained to be far more permissive on cybersecurity work. Announced on August 10, 2026. It is not publicly available.

On July 21, 2026, alongside Gemini 3.6 Flash and 3.5 Flash-Lite, Google announced a third model that is nothing like the other two. Gemini 3.5 Flash Cyber is purpose-trained for cybersecurity, and it is not generally available. It is a 3.5 Flash derivative fine-tuned to discover, validate, and remediate software vulnerabilities. It got its own separate post on the DeepMind blog, which itself says a lot about how differently Google treats this one. ...

Update: Claude Mythos 5.1 Is Out (September 1, 2026) The Mythos line was updated with Claude Mythos 5.1 on September 1, 2026. It is the identical model to Claude Fable 5.1, released the same day, with only the level of safeguards differing. It scores 60.9% on Terminal-Bench 4.0 against the Fable build’s 55.8%, and access stays limited to verified organizations under Project Glasswing. For benchmarks, pricing and API changes, read Claude Fable 5.1 . There is a new development every single day in the artificial intelligence world, but this time, the news is truly different. Anthropic announced a brand new model called Claude Mythos Preview on April 7, 2026. Moreover, they brought along a massive cyber defense initiative called Project Glasswing. ...
