Woofun AI notes that Kimi K3 has surpassed Anthropic's Opus 4.8 in benchmark evaluations. This performance shift is expected to compel U.S. frontier labs to accelerate the release schedules for Opus 5 and GPT-6. While OpenAI's GPT-5.6 Sol maintains a marginal lead over Kimi K3, the negligible gap suggests GPT-6 may launch ahead of its original timeline.
