Cerebras

This post details Cognition's co-design of their SWE-1.6 and SWE-grep agents with Cerebras Inference. It highlights the achievement of ~5x faster coding performance (up to ~950 tokens/second) compared to GPUs, enabling developers to explore large repositories and make precise code changes in under five seconds. The post emphasizes improvements in model UX, including more parallel tool calls, reduced looping, and greater reliance on agent tools over terminal commands. SWE-grep's Fast Context sub-agent collapses context gathering from tens of seconds into seconds. The combined optimization of model, agent harness, and inference layer delivers a cohesive agent experience tuned on real engineering workflows and model UX.
