Today's numbers at a glance

On the radar today#

🧠 Sessions can override an agent's model, prompt, tools and skills for one run#

Passing agent with type: "agent_with_overrides" on session create replaces the model, system prompt, tools, MCP servers or skills for a single session, leaving the stored agent unchanged.

The number: 5 (Agent fields overridable per session). platform.claude.com

Why it matters: It removes the main reason teams were versioning agents constantly: trying one different model or one extra tool no longer means publishing a new agent version.

🎬 Gemini ships a video generation and conversational editing preview#

Google released gemini-omni-flash-preview for high-speed video generation and conversational video editing, producing 3 to 10 second videos at 720p, and moved gemini-3.1-flash-lite-image to general availability.

The number: 3-10s (Video length generated by gemini-omni-flash-preview). ai.google.dev

Why it matters: Conversational editing is the interesting half. Generating a clip is table stakes now; revising one through dialogue is what makes video usable in an agent workflow.
