Mistral NeMo. Released by Mistral today: "Our new best small model. A state-of-the-art 12B model with 128k context length, built in collaboration with NVIDIA, and released under the Apache 2.0 license."

Nice to see Mistral use Apache 2.0 for this, unlike their Codestral 22B release - though Codestral Mamba was Apache 2.0 as well.

Mistral's own benchmarks put NeMo slightly ahead of the smaller (but same general weight class) Gemma 2 9B and Llama 3 8B models.

It's both multi-lingual and trained for tool usage:

The model is designed for global, multilingual applications. It is trained on function calling, has a large context window, and is particularly strong in English, French, German, Spanish, Italian, Portuguese, Chinese, Japanese, Korean, Arabic, and Hindi.

Part of this is down to the new Tekken tokenizer, which is 30% more efficient at representing both source code and most of the above listed languages.

You can try it out via Mistral's API using llm-mistral like this:

pipx install llm
llm install llm-mistral
llm keys set mistral
# paste La Plateforme API key here
llm mistral refresh # if you installed the plugin before
