B.AI API has announced a significant expansion of its model library, introducing four new AI models: GPT-5.5 Instant, DeepSeek-v3.2, MiniMax-M2.7, and GLM-5.1. According to ChainCatcher, the GPT-5.5 Instant model was integrated within 48 hours of OpenAI's release, enabling immediate utilization of next-generation computing power. Compared to its predecessor, GPT-5.3 Instant, the new GPT-5.5 Instant model reduces hallucination rates by 52.5% in high-precision fields such as healthcare, law, and finance, while enhancing logical clarity and output conciseness, thereby improving the reliability of complex tasks. These models are now fully available for B.AI API requests, allowing developers to access the latest model interfaces and experience stable and trustworthy AI capabilities without delay.
