AI Gateway adds DeepSeek Search and Fetch tools

DeepSeek Search and DeepSeek Fetch are now accessible through Vercel's AI Gateway, enabling users to find relevant web pages and retrieve their content as Markdown using a single API key. These tools work with any model supporting tool calling, support fallback search options, and are available in AI SDK versions 6.0.321 (v6) and 7.0.160 (v7). Each search or fetch request costs $0.75 per 1,000 billable requests, with no charge for failed or empty results. Usage is tracked via AI Gateway, which also supports routing, retries, and failover configurations.

Chat SDK agents can now stream generative UI with json-render

Vercel introduces json-render, enabling Chat SDK agents to generate and stream interactive UI components as JSON specs, which are converted into platform-native cards (e.g., Block Kit on Slack, Adaptive Cards on Teams). The system uses a typed component catalog covering tables, charts, buttons, and more, eliminating the need for separate tools. It supports streaming updates with real-time edits every 500 ms, validates component specs against schemas, and enforces platform-specific message limits to prevent content degradation.
