Claude Opus 5 Officially Available on B.AI API, Dual-Channel Access Balances Performance and Cost

The B.AI API platform officially launches the Claude Opus 5 model. This model provides 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 engineering development, large-scale document analysis, and knowledge-intensive workflows. To meet diverse deployment needs, this release simultaneously opens a dual-channel API access solution on the B.AI platform: in addition to the official standard interface, a new "Designated Service Provider" cooperation channel is added, through which enterprise users can obtain cost discounts of up to 40%, facilitating flexible balancing of performance and budget expenditure based on actual business loads. Developers can log in to the official B.AI platform starting today to experience the exceptional capabilities of Claude Opus 5 first.
