What Pareto can do.
Multimodal
Image understanding
Reads and reasons over images alongside text in the same prompt.
Development
Tool calling
Calls external functions mid-response, then continues reasoning from the result.
Streaming
Streams tokens as they're generated instead of waiting on the full response.
Pay for what you use.
Every model in UltraGPT runs behind one flat subscription — this is the underlying per-token cost the catalog tracks.
