Shuttle-2.5-mini (beta) [2024/07/27]
We are excited to introduce Shuttle-2.5-mini, our next-generation state-of-the-art language model designed to excel in complex chat, multilingual communication, reasoning, and agent tasks.
- Shuttle-2.5-mini is a fine-tuned version of Mistral-Nemo-Base-2407, emulating the writing style of Claude 3 models and thoroughly trained on role-playing data.
