DeepSeek Coder V2
DeepSeek's open-weight code-specialized mixture-of-experts model
DeepSeek-Coder-V2 is DeepSeek’s second-generation code model, released in June 2024 as a mixture-of-experts model with 236 billion total parameters and 21 billion active per token. It extended the context window to 128,000 tokens, up sharply from the 16,000-token window of the original DeepSeek-Coder, and expanded language coverage from 86 to 338 programming languages. On HumanEval it scored 90.2%, a result DeepSeek billed at the time as closing the gap with closed models like GPT-4 Turbo on coding tasks, and it also improved on general reasoning and math benchmarks compared to its predecessor. Unlike the original DeepSeek-Coder’s more restrictive license, DeepSeek-Coder-V2 is released under the MIT license, making it freely usable for commercial projects, and weights are available on Hugging Face alongside API access through DeepSeek’s own platform.
