X：OpenRouter

New in the OpenRouter Agent SDK: human-in-the-loop tools. Auto-resolve routine tool calls. Pause high-stakes ones for review. Return a value to keep the agent running. Return null to surface the call to your app for human input.

New server tool: Advisor Let smaller models consult a higher-intelligence "advisor" model. Helps them escape doom loops, and helps you migrate to cheaper models! 🧵

The Auto Router now lets you tune how it weighs cost against quality. New `cost_quality_tradeoff` parameter, 0 to 10: Set it to 0 and it always picks the most capable model regardless of price. Set it to 10 and the cheapest model wins.

Introducing Pareto Code: a new, free, experimental coding router Set `min_coding_score` in your request and route to the cheapest code-capable model that clears your bar, ranked by @ArtificialAnlys. See the Pareto frontier shifting in real time👇

openrouter's pareto router (for coding) is probably the most underrated way to save on ai coding costs you set the intelligence level+cost, we choose the best model for your use case also, we have workspaces which allows being able to set max usage thx @theinformation
