Users report that gpt-6-astra and claude-fable-5.1 have shown up on the model aggregation platform Experiential Labs, listed as free to chat with — just sign in, pick the model and start. The site lists GPT-6 Astra with a 1.05M context at $10/$50 per million tokens (released Sep 2026) and Claude Fable 5.1 with 1M context at the same pricing, both on free tiers alongside models like GPT-5.6 Luna and DeepSeek V4 Flash. The same author also shared a method to get four months of ChatGPT Plus via a "sheerid" student-verification flow, stressing that only legitimate student credentials should be used. Note: these model names and listings are unverified by OpenAI or Anthropic — treat with skepticism, and the workaround may violate terms of service.
