These are unhealed, experimental versions of DeepSeek-Coder-v2-lite-instruct created through model fusion. They are not ready for direct use and will exhibit unpredictable behavior without significant post-training. These models are released exclusively for research purposes and require a specific "healing" process to restore functionality. Do not use these models without understanding and applying the healing procedure.

What to Expect (Before Healing)

These models are in an initial, unstable state after the fusion process. Expect significantly degraded performance and unpredictable outputs. They are not representative of the final capabilities of a properly trained fused model. This is a very early iteration of the fusion and distillation technique, using a small sample size for distillation. Significant room for improvement remains in the distillation process.

Healing Instructions (Required)

Crucially, you must perform post-training to make these models usable. The necessary scripts and detailed instructions are available in the moe-pruner repository:

https://github.com/gabrielolympie/moe-pruner

Follow the instructions in that repository carefully to "heal" the pruned model. This process is essential to recover performance.

Contributing and Future Improvements

This release represents an initial exploration of model fusion and distillation. Due to hardware limitations, significant compromises were made during development.

We welcome contributions to improve this work! There are two primary ways to help:

Financial Support: Larger-scale experiments require significant compute resources. If you'd like to support future versions with a higher compute budget, you can donate here: https://gofund.me/1516dccd
Code Contributions: Suggest improvements, bug fixes, or new features directly on the GitHub repository.

We are actively working to improve the fusion and distillation techniques, and your contributions are greatly appreciated.

Disclaimer

These models are provided "as is" for research purposes only. No guarantees are made regarding their performance or stability before the healing process is completed. Use at your own risk.

AWQ quantized version of DeepSeek-Coder-V2-Lite-Instruct model.

DeepSeek-Coder-V2: Breaking the Barrier of Closed-Source Models in Code Intelligence

1. Introduction

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 DeepSeek-Coder-V2-Base with 6 trillion tokens sourced from a high-quality and multi-source corpus. Through this continued pre-training, DeepSeek-Coder-V2 substantially enhances the coding and mathematical reasoning capabilities of DeepSeek-Coder-V2-Base, while maintaining comparable performance in general language tasks. Compared to DeepSeek-Coder, 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 in the paper.

2. Model Downloads

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.

3. Chat Website

You can chat with the DeepSeek-Coder-V2 on DeepSeek's official website: coder.deepseek.com

4. API Platform

We also provide OpenAI-Compatible API at DeepSeek Platform: platform.deepseek.com. Sign up for over millions of free tokens. And you can also pay-as-you-go at an unbeatable price.

5. How to run locally

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.

Inference with Huggingface's Transformers

You can directly employ Huggingface's Transformers for model inference.
