DeepSeek Coder V2 Instruct AWQ is an artificial intelligence model specialized in code generation and comprehension, designed to rival closed models like GPT-4 Turbo in programming tasks. With its advanced architecture and extensive training on billions of tokens, it excels particularly in solving complex problems, analyzing code, and assisting with software development. The model stands out for its ability to handle both pure coding tasks and applied mathematical reasoning while maintaining strong performance in general language domains. It caters to developers, researchers, and businesses seeking a high-performing open-source solution to automate or optimize their programming workflows. Its quantization-based approach also makes it more resource-efficient without compromising accuracy.
This model was quantized on 4x A100 80GB with 1TB system ram. It was quantized using the chosen preferences from the coding dataset of OpenHermes 2.5: https://huggingface.co/datasets/alvarobartt/openhermes-preferences-coding

We present DeepSeek-Coder-V2, an open-source Mixture-of-Experts (MoE) code language model that achieves performance comparable to GPT4-Turbo in code-specific tasks. Specifically, DeepSeek-Coder-V2 is further pre-trained from an intermediate checkpoint of DeepSeek-V2 with additional 6 trillion tokens. Through this continued pre-training, DeepSeek-Coder-V2 substantially enhances the coding and mathematical reasoning capabilities of DeepSeek-V2, while maintaining comparable performance in general language tasks. Compared to DeepSeek-Coder-33B, DeepSeek-Coder-V2 demonstrates significant advancements in various aspects of code-related tasks, as well as reasoning and general capabilities. Additionally, DeepSeek-Coder-V2 expands its support for programming languages from 86 to 338, while extending the context length from 16K to 128K.
In standard benchmark evaluations, DeepSeek-Coder-V2 achieves superior performance compared to closed-source models such as GPT4-Turbo, Claude 3 Opus, and Gemini 1.5 Pro in coding and math benchmarks. The list of supported programming languages can be found here.
We release the DeepSeek-Coder-V2 with 16B and 236B parameters based on the DeepSeekMoE framework, which has actived parameters of only 2.4B and 21B , including base and instruct models, to the public.

You can chat with the DeepSeek-Coder-V2 on DeepSeek's official website: coder.deepseek.com
We also provide OpenAI-Compatible API at DeepSeek Platform: platform.deepseek.com, and you can also pay-as-you-go at an unbeatable price.
Here, we provide some examples of how to use DeepSeek-Coder-V2-Lite model. If you want to utilize DeepSeek-Coder-V2 in BF16 format for inference, 80GB*8 GPUs are required.
You can directly employ Huggingface's Transformers for model inference.

The complete chat template can be found within tokenizer_config.json located in the huggingface model repository.
An example of chat template is as belows:
<|begin▁of▁sentence|>User: {user_message_1}
Assistant: {assistant_message_1}<|end▁of▁sentence|>User: {user_message_2}
Assistant:
You can also add an optional system message:
<|begin▁of▁sentence|>{system_message}
User: {user_message_1}
Assistant: {assistant_message_1}<|end▁of▁sentence|>User: {user_message_2}
