Seed 2.0 Lite API

ByteDance Seed's Seed 2.0 Lite, through an OpenAI-compatible API. Providers quote it on an open exchange, and each request goes to the offer with the lowest estimated charge that meets your rules.

Providers compete for each request. The exchange ranks the offers that meet your rules by estimated charge. It fixes your maximum charge before the first token, and you pay for the tokens that the model uses.
The OpenAI and Anthropic APIs. Use the OpenAI or Anthropic SDK that you have. Set the base URL and your key, and send seed-2.0-lite as the model.
Your data rules. Send x-liquid-retention: none and only offers whose provider does not keep your content compete for the request.
