Open-source large language model for code, trained on permissively licensed data from GitHub by BigCode and HuggingFace.
Pros
- +Completely open source and free
- +Self-hostable for privacy
- +Multiple model sizes available
- +Permissive licensing
Cons
- -Requires technical setup to self-host
- -Less capable than GPT-4 based tools
- -No built-in IDE integration
What Is StarCoder?
StarCoder is an open-source code generation model trained by BigCode on permissively licensed code. It is the most transparent AI coding model available — you can inspect the training data, fine-tune it, and run it locally.
What We Like
For organizations that care about the provenance of AI training data, StarCoder is unique. The training dataset (The Stack) only includes code with permissive licenses, reducing IP concerns. The model runs locally, so no code leaves your infrastructure. Performance on code completion rivals commercial alternatives for common programming tasks.
What Could Be Better
Out-of-the-box, StarCoder requires more setup than commercial tools — you need to configure inference, choose a UI, and manage model files. Performance on complex reasoning tasks trails GPT-4 and Claude significantly. The IDE integration experience is less polished than GitHub Copilot or Cursor.
Pricing
Completely free and open-source. Run locally on your own hardware (requires a GPU with 16GB+ VRAM for full model) or access via Hugging Face API. Zero licensing costs for any use.
