Aya 23 35B

Aya 23 35B is the larger model of the pair Cohere Labs released on 23 May 2024, when the Aya programme dropped from 101 languages to 23 and put the freed capacity into each remaining language. At 34,980,831,232 parameters it is the largest model the lab has ever published under the Aya name - larger than Aya Expanse 32B, which replaced it five months later with 2.7 billion parameters fewer. That detail is worth keeping in mind when reading the family as a progression: the line did not simply grow. It went from 12.9 billion parameters across 101 languages (Aya 101, Apache 2.0), to 35 billion across 23 (this model), to 32.3 billion across the same 23 (Aya Expanse 32B), to 3.35 billion across 70-plus (Tiny Aya, February 2026) - four different answers to the same question about how to spend capacity on languages. Licensing did not move at all after the first step: CC BY-NC 4.0 and Cohere Labs' acceptable use policy, no commercial grant, weights behind a gate requiring an account. Downloads are correspondingly thin - 486 in the thirty days to 18 August 2026 - though 291 likes suggest the model is still widely regarded as a multilingual reference point.
