What is WebLLM and how does it run LLMs in browser?

WebLLM from MLC AI compiles models to WebGPU/WASM, loads from HuggingFace, caches locally. OpenAI API drop-in with JSON schema enforcement.

Can browser LLMs replace local setups like Ollama for gaming tools?

Yes, for frictionless apps — 24s first load, 2s repeats, 50 t/s, beats unconstrained Ollama on quality via hard schema rules.

Does WebLLM work on my hardware for AI coaching?

Thrives on Apple Silicon (M3+), Chrome WebGPU. 1-2GB models fit most gaming rigs; watch memory if under 16GB RAM.
