Claude Opus 5 officially joins B.AI API, with dual-channel access balancing performance and cost

The B.AI API platform officially launches the Claude Opus 5 model. This model offers a context window of up to 1 million tokens and a single output limit of 128,000 tokens, achieving significant performance leaps in scenarios such as complex reasoning, long code project development, large-scale document analysis, and knowledge-intensive workflows.

To meet diverse deployment needs, this release synchronously opens a dual-channel API access solution on the B.AI platform: in addition to the official standard interface, a new "designated service provider" collaboration channel has been added. Enterprise users can obtain up to a 40% cost discount through this model, making it easier to flexibly balance performance and budget expenditures based on actual business loads. Developers can log in to the B.AI official platform starting today to experience the exceptional capabilities of Claude Opus 5 first-hand.
