Nemotron 3 Ultra 是英伟达（NVIDIA）专为 Agentic AI 和复杂逻辑推理打造的高性能大模型。在 OpenCode 平台当前处于限时免费试用阶段。
OpenCode Zen 联合各大模型厂商为收集开发者社区反馈，目前限时免费提供该模型。只需在 https://opencode.ai/auth 免费获取 API Key 即可使用标准 OpenAI 格式调用。
可在任何支持 OpenAI 格式的客户端（如 OpenAI Python SDK、Cursor、OpenCode CLI 或本站 Playground）中填写 Base URL 为 https://opencode.ai/zen/v1 即可调用。
