Ask any text/chat model on 370.ai (Claude / GPT / Gemini / DeepSeek / Qwen / ...) and get its reply. Use this when you want a **specific or different** model than your own — e.g. consult Claude while you run on GPT, use a cheaper model for bulk work, or reach a model you don't have direct access to. One key, 100+ models. Call list_models to see the full catalog of model ids. Args: prompt: the user message / question. model: model id to call (see list_models). Empty = a fast cheap default. system: optional system instruction to steer the model. max_tokens: optional cap on output length (omit to let the model decide). temperature: optional sampling temperature 0..2 (omit for the model's default). Returns the model's text reply.

Generate an image from a text prompt. Use whenever the user wants a picture/illustration/photo created. Args: prompt: description of the image (English works best). size: 1024x1024 (square) / 1024x1536 (portrait) / 1536x1024 (landscape). Returns the generated PNG image.

Convert text to spoken audio. Billed per input character on your key. Args: text: the text to speak. voice: voice id. The OpenAI voice names (alloy / echo / fable / onyx / nova / shimmer) are accepted, but on the default model they are all mapped to the same default voice, so they sound identical. To pick a different voice, pass a voice id supported by the model (for the default model, e.g. Cherry or Ethan). Returns a short status line plus the generated audio as an audio content block (mimeType as returned by the gateway, e.g. audio/mpeg).
