B.AI said on September 2 that its Responses API now supports DeepSeek series models. According to Odaily, developers can use a B.AI API key to call the DeepSeek models supported by the platform directly in the Codex client.
B.AI had previously supported GPT series models through Codex. The company said the new integration expands model options in the Codex environment, allowing developers to switch between DeepSeek and GPT after simple API key and Base URL configuration for code generation, understanding, debugging, refactoring, and collaboration tasks.
