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.

corrigan38: a 1.58-bit (ternary weights) email-writing transformer, running on your CPU in this tab via WebAssembly SIMD and threads. Named after Douglas “Wrong Way” Corrigan, who flew from New York in 1938 and ended up in Dublin. Scores are self-reported by browsers: for fun, not for procurement.
