### Model Overview:

Mistral-NeMo-12B-Base 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
- Trained on a large proportion of multilingual and code data

### Intended use

Mistral-NeMo-12B-Base is a completion model intended for use in over 80+ programming languages and designed for global, multilingual applications. It is fast, 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. It is compatible with [NVIDIA NeMo Framework](https://docs.nvidia.com/nemo-framework/index.html). For best performance on a given task, users are encouraged to customize the model 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](https://github.com/NVIDIA/NeMo-Aligner).

**Model Developer:** [NVIDIA](https://www.nvidia.com/en-us/) and [MistralAI](https://mistral.ai/)

**Model Dates:** Mistral-NeMo-12B-Base was trained between May 2024 and June 2024.

### 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.

### Ethical Considerations

NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications.  When downloaded or used in accordance with our terms of service, developers should work with their internal model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
