Moonshot's Kimi K3, with 2–3 trillion parameters, aims to match Anthropic's Opus 4.8

Moonshot’s upcoming Kimi 3 is expected to close the gap with Anthropic’s Opus 4.8

Moonshot AI is about to release Kimi K3, reportedly China's largest open-weight model with 2–3 trillion parameters. The FT, citing anonymous sources, says it will match or beat Anthropic's Opus 4.8. Kimi K2 already ranked well on open-source benchmarks; K3 aims to close the gap with closed-source leaders from OpenAI and Anthropic. Moonshot is also raising a new round at a reported $31.5B valuation, after a $2B raise in May. The post doesn't give a specific launch date or benchmark scores, only 'in the coming days.'

Why it matters: Kimi K3 rumored to match Opus 4.8 with 2-3T open-weight params — a significant signal in the China-vs-closed-source race. Score held at 82 because all sources are anonymous, no benchmarks disclosed, no release date confirmed — it's expectation, not evidence yet.
