GPT-6 Astra and Claude Fable 5.1 are now hosted models: any workspace can run them on General Input's provider keys without connecting a subscription. Until now both were reachable only through [Token Tunnel](/token-tunnel). Compare them on the [models page](/models).

### What changed

- **GPT-6 Astra:** a 1,050,000-token context, at $10 per million input tokens and $50 output, with cache reads at $1. Above 272,000 input tokens, input bills at 2x and output at 1.5x.
- **Claude Fable 5.1:** a 1,000,000-token context and up to 128,000 output tokens, at $10 input and $50 output, with cache reads at $0.25.
- **Same-model failover.** Both are also served through Vercel AI Gateway and OpenRouter, so an overload moves the same model to another route before any fallback.
- **Long-context pricing** is now a catalog field: an input threshold plus multipliers. Each request in a long run is priced against its own context size.

### Also shipped

- GLM 5.3 replaces GLM 5.2, and GLM 5.3 Flash joins with a 1M-token context.
- DeepSeek V4.1 Flash replaces V4 Flash, adds vision, and costs half as much: $0.22 input and $0.66 output per million tokens.
- Token Tunnel now delivers instructions to Claude and ChatGPT subscriptions as a real system prompt.
