Moonshot AI
AI startup founded in Beijing in 2023, creator of the Kimi models and spearhead of the Chinese wave of open-weight models. Its Kimi K3, unveiled in July 2026 with 2.8 trillion parameters, is presented as the largest open model ever released.
In other words
Its name comes from "moonshots," those almost impossible technological bets, like going to the Moon.

- Kimi K3 burns through twelve times more reasoning tokens than Claude Opus: the hidden cost of thinking
An analysis of Kimi K3's reasoning traces reveals it consumes more than twelve times as many reasoning tokens as Claude Opus 4.8. This is both the secret to its performance and its biggest economic flaw. We explain the mechanism, and why the price per token says nothing about the real cost.
- Kimi K3: the largest open model ever built comes from Beijing, and it is nipping at the heels of the best
On 16 July 2026, Moonshot AI launched Kimi K3, a 2.8-trillion-parameter model billed as the largest open-weight model ever released. It ranks just behind Fable 5 and GPT-5.6 Sol, and even edges ahead of them on some benchmarks. We break down its numbers, its true standing, and the important nuance behind the word "open."
