Mistral-NeMo-12B-Instruct

Model Overview:

Mistral-NeMo-12B-Instruct is a Large Language Model (LLM) composed of 12B parameters, trained jointly by NVIDIA and Mistral AI. It significantly outperforms existing models smaller or similar in size.

Key features

Released under the Apache 2 License
Pre-trained and instructed versions
Trained with a 128k context window
Comes with a FP8 quantized version with no accuracy loss
Trained on a large proportion of multilingual and code data

Intended use

Mistral-NeMo-12B-Instruct is a chat model intended for use for the English language.

The instruct model itself can be further customized using the NeMo Framework suite of customization tools including Parameter-Efficient Fine-Tuning (P-tuning, Adapters, LoRA, and more), and Model Alignment (SFT, SteerLM, RLHF, and more) using NeMo-Aligner.

Limitations

The model was trained on data that contains toxic language, unsafe content, and societal biases originally crawled from the internet. Therefore, the model may amplify those biases and return toxic responses especially when prompted with toxic prompts. The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive.
