Mythos is live! so excited to have our FrontierCode recognized as the next frontier coding bench. on FC Diamond, BOTH Opus 4.8 and GPT 5.5 don't meaningfully scale with effort, which many of you caught yesterday. Mythos/Fable posttraining have really applied that test time compute toward solving very, very long running problems - dozens of human hour equivalents, hundreds of dollars per task, for the first time ever measured. Available now in @Cognition @Devin for only 1.4x ACUs too! (I never thought i'd see this launch lol) It's finally out!!! @METR_Evals found that more than half of SWEBench results is unmergeable slop. FrontierCode represents over 1000+ hours of maintainer validated software engineering work most frontier models cannot yet solve, much less solve with high quality. Cog had IOI Gold…
