Benchmark #4 - live OpenCode sessions

5 real headless OpenCode sessions (qa + coding + read-tool): wall 18.4-21.1 s per prompt, output 48-120 tok, end-to-end 2.5-6.5 tok/s (median 5.07). Decode ~3.5x slower at 23k depth than shallow.

What was found

OpenCode system prompt is ~23,462 tokens - every single-turn request pays ~10-11 s prefill (agent harness context floor)
