B.AI said on September 12 that its latest model access benefits have taken effect, including a 90% discount for high-concurrency models DeepSeek-V4.1-Flash and GLM-5.3-Flash. According to ChainCatcher, users can now call these models at 10% of the original price, while Qwen3.8-Flash, Hy3, and MiMo-V2.5 remain fully free to use.

The company said the pricing update is intended to support high-throughput demand and lower the barrier for developers exploring multiple models.
