How fast is your CPU at writing emails?

A tiny ternary-weight LLM runs in your browser, no server involved. Tokens per second and time to first token, measured on real CPUs.

Run the benchmark
#NameCPUThreadsTokens / secondTime to first token

Best score per name + CPU. Tokens/second is the median of 10 steady-state runs at the thread count that scored best (threads used / cores the browser reports); the small grey range is the slowest and fastest run. Time to first token is the median over 10 real short emails.

A 1.58-bit (ternary weights) email-writing transformer, running on your CPU in this tab via WebAssembly SIMD and threads. Scores are self-reported by browsers: for fun, not for procurement.
