Helium-1
2B multilingual text model designed for edge and mobile
About
Helium-1 is a 2-billion-parameter text model from Kyutai, released on January 13, 2025 under CC-BY 4.0. It targets edge and mobile deployment with support for six European languages and runs in standard Hugging Face Transformers. Its benchmark profile sits near other 2B-class models like Gemma-2 2.6B, which is respectable but not a leap forward. It is a plain small language model, not a speech model despite Kyutai's audio reputation.
