Aya Expanse 8B

Aya Expanse 8B brings Cohere's 23-language Aya approach into an open 8-billion-parameter checkpoint. The underlying research combines multilingual preference training, safety tuning, and model merging. The checkpoint consequently stays focused on translation and instruction tasks, without visual understanding or built-in tools.

The 8-billion-parameter model provides an 8,000-token context, considerably narrower than Aya Expanse 32B. The weights use CC-BY-NC-4.0, which rules out unrestricted commercial use.
