BAI Expands AI API With Frontier Models

BAI is positioning itself as model-access infrastructure, but its long-term value will depend on routing reliability, pricing transparency, and trust—not just catalog breadth.

• –Supports models including GPT-5.5, Claude Opus 4.8, Gemini 3.5 Flash, DeepSeek V3.2, Kimi K2.5, and GLM-5.1 ([official model documentation](https://docs.b.ai/llmservice/Claude%20Code/Claude%20Code%20x%20B.AI%20API%20Configuration%20Guide/)).
• –OpenAI-compatible chat completions and Anthropic-compatible messages APIs reduce migration friction for existing applications ([API documentation](https://docs.b.ai/llmservice/api/)).
• –Multi-model access gives developers flexibility to balance capability, latency, and cost across workloads.
• –Privacy-first positioning and crypto-native payments may appeal to autonomous agents and Web3 developers, but could introduce compliance and operational concerns.
• –BAI competes in an increasingly crowded gateway market alongside OpenRouter, LiteLLM, and provider-native aggregators.
