Claude Fable 5.1 and GPT-6 Astra are now available in Webair AI
Anthropic’s Claude Fable 5.1 and OpenAI’s GPT-6 Astra are live inside Webair AI. Pick either one for your hardest work, run them side by side in Compare, and see exactly which model answered you — all on the same private Brain.
Two of the most capable AI models ever released are now inside Webair AI. Claude Fable 5.1 is Anthropic’s newest and strongest model. GPT-6 Astra is OpenAI’s new flagship. Both are live today for Pro+ and Max.
Choose either one from the model picker when you want the strongest thinking on a hard problem — a tricky negotiation, a long contract, a plan with a lot of moving parts. Or put them side by side in Compare and watch how each one handles the same question.
Every response now tells you who answered. Look under any reply and you’ll see the model that produced it — and when you’re on Auto, why Cortyx picked it. No more guessing which AI you’re talking to.
Long conversations got lighter on your Brain activity. Webair AI now reuses what it already knows about a conversation instead of re-reading everything on every turn, so extended sessions use less of your monthly allowance.
Texting got more dependable too. If a text from Webair AI fails to deliver, it is resent automatically. When Webair AI is working on something that takes a minute — like a live web task — it texts you “On it” so you are never left wondering. And if your Brain activity runs low, you get a heads-up before anything pauses, on the web and over text.
Like every model in Webair AI, Fable 5.1 and Astra run on your private Brain. Your business context comes along, and your data is never sold or used to train any public model.
Business owners can now use Anthropic’s Claude Fable 5.1 and OpenAI’s GPT-6 Astra inside Webair AI — the two newest frontier AI models, available on Pro+ and Max, grounded in your own private company Brain and never used to train public models.
