v1.0 focused on software engineering and terminal tasks. Next we will test the full harness × model grid. Much of what we observed points to harness-model fit rather than harness quality, and we want to identify which combinations maximize pass rates while minimizing cost. 17.9K views · 109 likes · 3 reposts · 16 replies Open on X →

Something we learned: With implicit prefix caching, running a task once during debugging leaves it warm for hours. Test a harness on Tuesday, benchmark it Wednesday, and it shows up cheaper than it should. Nothing in the logs tells you why. So no benchmark task was touched http 15.9K views · 53 likes · 0 reposts · 4 replies Open on X →

If you just want to know what to use: Codex if you don't want to think about it. Best pass rate, medium cost. Pi if the same job runs a thousand times and the bill adds up. Exo if retries are cheap and you'd rather it quit early than grind. DSH if you care about wall-clock and h 18.1K views · 130 likes · 7 reposts · 4 replies Open on X →

Here is the run that made us write this up. One of the hardest tasks, the pass rate (all model efforts) on DeepSWE is 38%, Pi and Claude Code both fixed it. Pi took 90 turns and $2.50. Claude Code took 381 turns and $64.36. Roughly 26x more for the same fix. https://t.co/VCX37w 22.1K views · 145 likes · 6 reposts · 9 replies Open on X →
