Claude AI Chat
Claude in the Developer Studio, alongside GPT-5.6, Gemini and Ling, with file uploads, live web search and reasoning effort you control per message. Chat costs no credits. Members get a free daily allowance measured in real provider cost, and Anthropic prompt caching means a long conversation does not re-pay for its own history every turn.
