TokenTable offers free API access to GPT-6 Astra and other models
The platform says users can sign up for a free API key to try GPT-6 Astra, Claude, Grok, Gemini and others, but main-model quotas are limited and requests silently fall back to Side models once they run out.

Free access to some of the biggest AI models on TokenTable 👀 You can try models like: • GPT 6 Astra • Claude Fable 5.1 • Claude Opus 5 • GPT 5.6 • Grok • Gemini • Qwen • GLM • Kimi How to get started: 1. Go to http://tokentable.asia 2. Sign up with email or Gmail 3. Create an API key 4. Use the base URL: http://tokentable.asia/v1 5.
