DeepSeek AI has officially launched DeepSeek-V2.5, a groundbreaking open-source model that seamlessly integrates general conversational abilities with robust code processing power. This latest iteration combines the strengths of DeepSeek-V2-0628 and DeepSeek-Coder-V2-0724, offering users a more streamlined, intelligent, and efficient AI experience.
DeepSeek-V2.5 is a versatile AI model designed to excel in both general conversation and coding tasks. It builds upon previous versions, incorporating enhancements that align better with human preferences and significantly improve writing and instruction-following capabilities. This all-in-one model is accessible via both web and API, utilizing backward-compatible API endpoints through deepseek-coder or deepseek-chat.
Key features like Function Calling, FIM (Fill-in-the-Middle) completion, and JSON output remain unchanged, ensuring a smooth transition for existing users.
The development of DeepSeek-V2.5 is a testament to DeepSeek's commitment to continuous improvement. Here's a quick recap of the key milestones:
DeepSeek has consistently focused on model refinement and optimization. In June, they upgraded DeepSeek-V2-Chat by replacing its base model with the Coder-V2-base, significantly enhancing its code generation and reasoning capabilities. This led to the release of DeepSeek-V2-Chat-0628. Shortly after, DeepSeek-Coder-V2-0724 was launched, featuring improved general capabilities through alignment optimization. Ultimately, DeepSeek successfully merged the Chat and Coder models to create the new DeepSeek-V2.5.
DeepSeek-V2.5 demonstrates superior performance across a wide range of industry-standard benchmarks compared to its predecessors, DeepSeek-V2-0628 and DeepSeek-Coder-V2-0724. Internal evaluations, particularly in Chinese, reveal significant improvements in win rates against models like GPT-4o mini and ChatGPT-4o-latest, especially in content creation and Q&A tasks. This translates to a richer and more satisfying user experience.
A critical aspect of DeepSeek-V2.5 is its enhanced safety measures. The developers have focused on clearly defining the boundaries of model safety, making it more resistant to jailbreak attacks while minimizing the impact of safety policies on normal, everyday queries.
| Model | Overall Safety Score (higher is better) | Safety Spillover Rate (lower is better) |
|---|---|---|
| DeepSeek-V2-0628 | 74.4% | 11.3% |
| DeepSeek-V2.5 | 82.6% | 4.6% |
These scores, based on internal test sets, highlight the significant strides made in ensuring a safer and more reliable AI experience.
DeepSeek-V2.5 retains the robust coding capabilities of DeepSeek-Coder-V2-0724, with notable improvements in the HumanEval Python and LiveCodeBench tests. While there were slight variations in performance across different coding benchmarks, DeepSeek-V2.5 excels in common coding scenarios, providing an optimized user experience.
In internal subjective evaluations, DeepSeek-V2.5 achieved a significant win rate increase against competitors, with GPT-4o serving as the judge. This underscores the model's superior coding prowess.
DeepSeek-V2.5 is now available as an open-source model on Hugging Face, encouraging community collaboration and further development:
