Vercel released version 4.0.78 of @ai-sdk/openai, a patch that adds support for setting reasoningEffort to 'none' for GPT-6 Sol and Luna models. The update also introduces validation logic that warns on unsupported request-level effort updates and rejects invalid historical ones.

OpenAI released Agent Plugins, a vendor-neutral standard for packaging Agent Skills and MCP servers into portable extensions, one day before GPT-5's first anniversary. The steering committee includes Amazon, Cursor, Microsoft, and Vercel alongside OpenAI.
