What is Hy4 Preview?
Hy4 Preview is a language model served through the OpenCode Go API. This page tracks its real inference speed — tokens per second, time to first token, and 24-hour reliability — sampled every ~6 hours on the same fixed prompt and the same measurement method used for every other model, so the numbers are directly comparable across providers. See the full methodology for how each sample is taken.

Reliability
Every benchmark attempt counts here — including timeouts and errors. TPS and TTFT charts above show successful runs only, so you can still see speed data while reliability is red.
Speed is measured as output tokens ÷ generation time. Each benchmark fires one streaming chat completion with a fixed ~300-token prompt, every ~6 hours. Full methodology →
