Chat completion on a frontier model: GPT-6.1 Sol and Terra, GPT-5.5, Claude Sonnet 5.5 and Haiku 5.5, Gemini 3.8 Flash, Grok 4.7, GPT-6 Luna, gpt-oss (default anthropic/claude-haiku-5.5; see the models tool). Same shape as OpenAI chat: messages, optional max_tokens (default 1024, max 8192), temperature, tools. Price is quoted per call from your input size and max_tokens: (estimated input tokens x input rate + max_tokens x output rate) x 1.4 + $0.0005, minimum $0.002; the 402 states the exact amount. Charged only if the model call succeeds. Thinking models (GPT-5.5, Gemini, Grok, gpt-oss) spend part of max_tokens on reasoning: give them room, or set reasoning_effort (default low). Prompts go to the model's provider via Cloudflare AI Gateway and are not stored by AgentDrop. No streaming.
