# W3C Web Machine Learning Working Group
The W3C standards body developing and ratifying web-based machine learning APIs. Coordinates cross-browser implementation of ML specifications, maintains technical documents, and facilitates community contributions. Commonly called the WebML WG.

## Charter and Scope
- Chartered through April 2027
- Produces normative W3C specifications for browser-native ML
- Coordinates with browser vendors (Google, Microsoft, Apple, Mozilla) for implementation
- Operates the [[WebMachineLearning]] GitHub organization
## Key Deliverables
| Specification | Status (2026) |
|---|---|
| [[WebNN API]] | W3C Candidate Recommendation |
| [[Prompt API]] | Early incubation |
| [[Writing Assistance APIs]] | Early incubation |
| Translation API | Incubation |
| Proofreader API | Incubation |
## How It Relates to Other W3C Groups
- **Web Platform Incubation Community Group (WICG)**: early-stage proposals incubate here before moving to the WG
- **W3C Web Performance WG**: aligned on hardware access and performance primitives
## Why It Matters
Standardization ensures that ML capabilities on the web are:
- Interoperable across browsers without vendor-specific SDKs
- Built with security and privacy considerations baked into specs
- Stable APIs that developers can depend on long-term
