DeepSeek Coder 33B Instruct
DeepSeek Coder 33B Instruct, released in November 2023, was DeepSeek AI's flagship open-weights code model before the DeepSeek-Coder V2 MoE series. Trained on two trillion tokens spanning 80+ programming languages with a project-aware packing strategy, it led open-weights HumanEval scores at launch and set a template that later Chinese-lab coding LLMs followed.

Frequently asked questions
What is DeepSeek Coder 33B Instruct?
DeepSeek Coder 33B Instruct is DeepSeek AI's 33-billion-parameter open-weights coding LLM, released in November 2023 and trained on two trillion tokens spanning 80+ programming languages.
Is DeepSeek Coder 33B still competitive?
For modern projects, DeepSeek-Coder V2 or Qwen2.5-Coder is usually a better choice. The 33B instruct model remains a strong baseline and useful fine-tuning base.
Where can I download DeepSeek Coder 33B?
Weights and instruct checkpoints are available on Hugging Face under the 'deepseek-ai' organisation with permissive licensing.
