Web Models proposes the browser local model API navigator.models
Understand this story
Web Models proposes a browser API, navigator.models, at the WICG, letting web pages request that a specified open-weight model run locally on the device by model ID, with the browser handling permissions and execution. The proposal is currently open for comment. Under the proposal's design, the first access request must be triggered by a user gesture; websites can detect whether the API exists but cannot list the models on the device; one authorization corresponds to only one top-level site, one requester frame origin, and one model ID.

A WICG proposal introduces navigator.models, a browser API that lets web apps request a specific open-weight model by ID, with the user granting access and the browser handling execution. The API covers generate(), stream() and embed(), with per-site permissions, shared model weights, and resource limits, while model ID governance and cross-browser compatibility remain open questions.
