o lose its edge over a single mega-cluster. How ARCv3 deltas move from trainer to rollouts. Each trainer shard uploads its slice of the compressed weight delta to shared object storage (S3) in parallel. Then, the Fireworks API signals every region that a new update is available, and each rollout region pulls the pieces it needs and reconstructs the updated model locally. The trainer never talks directly to the rollout fleet, which is what lets a globally distributed inference cluster stay in syn

Step Code is built for strong task completion without wasteful token use. On Terminal-Bench 2.1, it passed 72/89 tasks (80.9%), tying for the highest pass rate among the harnesses in our evaluation while using fewer tokens than the other tied leaders. On Multi-Frame, it passed 110/150 tasks (73.3%) and averaged 5.09M tokens/task—the highest pass rate and lowest token use among six harnesses evaluated.

s use specialized open-source models for tasks like modeling the structure of molecular systems, designing drug-like molecules, and predicting the effects of genetic mutations. But these models are often expensive to run, potentially limiting their impact. In our latest Science Blog, we share how Claude was able to optimize inference for more than 30 open-source models, making them 4x faster on average, partly by writing custom software for GPUs. We’re open sourcing all of the optimization code.

But with the same sidekick, Fable-led sessions cost 9% less on average, while scoring higher on FrontierCode. Fable delegated earlier and gave better briefs, while Opus micromanaged the sidekick and redid much of its work. The same principle applies to the sidekick.
