Agents, Workers - Agents can respond to MCP elicitation requests

Google's September AI roundup pairs new Gemini models with wider app integrations. The company says Gemini 4 Argon has a million-token context window and is rolling out first to trusted cyber defenders through Fairwind, with broader access planned after feedback on safeguards. Other announcements include Gemini on Windows, more Connected Apps, and WeatherNext 3 forecasts integrated into Search, Gemini, Maps and Cloud.

Web Search API is now available in beta. Web Search API lets your AI agents and applications search the Internet and ground their responses in live information, instead of guessing URLs or relying on a model's training cutoff. At launch, you can choose between three search providers: Ceramic.ai, Exa, and Linkup. All three support Zero Data Retention for requests made through Cloudflare, and all have committed to Cloudflare's verified bot crawling standards. Web Search API runs through AI Gateway, so search requests appear in your gateway logs and are billed to your AI Gateway credits at each provider's list API price, with no additional markup. You can also bring your own provider API key.

Google Cloud describes an AI-agent memory design that keeps recent conversations in Memorystore for Valkey and durable facts, preferences and events in AlloyDB. The tutorial combines hybrid retrieval with database-managed embeddings, tenant isolation and memory cleanup. Google reports token and latency reductions from an internal simulated developer workload, while cautioning that savings vary with prompt structure, query frequency and data volume.

Vercel says financial AI company Rogo is rebuilding internal applications on its platform and deploying agent-written code in five minutes. The customer case study reports more than 73,000 deployments in one month and six production AI agents handling work including churn analysis and deal support. Vercel also describes automated production-incident triage and remediation using its AI SDK.

Cloudflare has added PiHarness to its Agents SDK, connecting Pi-based agents to Durable Objects. The company says this integration preserves work across interruptions and can keep long-running tasks alive through restarts, crashes and network problems. It supports Workers AI, AI Gateway and existing pi-ai providers. PiHarness remains in beta; Pi Durable is experimental, and the interface is likely to change.

GitHub has opened a public preview of computer use in Copilot CLI and the Copilot app for macOS and Windows. The assistant can work through desktop interfaces, including software without an API or command line. GitHub says users approve app control and can review those permissions; managed organizations can disable the feature. On macOS, additional accessibility and screen-recording permissions are required.
