AI Weekly · Kimi AI·
Kimi K3 achieves 2.8 trillion parameters with 1M token context window, becoming the first open-source model to reach this scale. The model ships with native vision capabilities and is priced at $3.00/$15.00 per 1M tokens, ranking #4 globally on Artificial Analysis leaderboard behind Claude Fable 5 and OpenAI GPT-5.6 Sol. Kimi models have maintained the open-source scale frontier in 9 of the past 12 months.
Technical significance
The Kimi K3 breakthrough shatters the open-source scaling barrier, reaching 2.8T parameters while maintaining competitive pricing. This democratizes access to frontier models and pressures closed-source providers to accelerate their own scaling efforts.
