FireFlash builds frontier coding agent with just 64 B300 GPUs in 5 days

FireFlash released a 300B long-horizon coding agent post-trained from GLM-5.3-Flash, reaching the Terminal-Bench Pareto frontier with only 64 B300 GPUs in 5 days. The team attributes the result to domain specialization over general scaling, achieving frontier-level performance at far lower training and inference cost.
