Show HN: Doppler.js – WebGPU inference, faster/simpler than transformer.js
Doppler.js: https://github.com/clocksmith/doppler
Live demo: https://d4da.com (bring your own safetensors or use the Gemma samples)
Core problem: for browser-local inference loops, TVM/ORT-style stacks can be hard to inspect and iterate on.
Thesis: - Keep development and runtime build-free (JS + WGSL only) - Make execution choices explicit, benchmarkable, traceable, and profilable
Solution: - Explicit model/kernel-path control - Browser + CLI contract parity (Node must run WebGPU, or use headless browser with WebGPU) - Reproducible phase benchmarks vs Transformers.js (v4) - Artifacts: https://github.com/clocksmith/doppler/tree/main/benchmarks/v...
Request: if this is flawed or pointless, please tell me exactly where or why. If I’m flawed or pointless, well...technical feedback only please =)
