Overview
Their paper documents training data and model capabilities, while the OpenRAIL-M license permits use subject to stated restrictions.
Deep Dive
The 2023 BigCode paper introduced StarCoderBase and StarCoder as 15.5-billion-parameter code models with an 8,000-token context. StarCoderBase was pretrained on about one trillion tokens from The Stack, and StarCoder was produced by further fine-tuning StarCoderBase on 35 billion Python tokens. The paper describes fill-in-the-middle training, multi-query attention, data documentation, opt-out mechanisms, and release under BigCode’s OpenRAIL-M license. StarCoder2 is a later, separate model family introduced in 2024.
Real-World Implementation
Powering autocomplete and code-completion suggestions inside IDE plugins and editor extensions
Generating boilerplate functions, unit tests, and docstrings from a natural-language comment
Translating or refactoring code between programming languages within an enterprise codebase
Serving as a self-hostable coding assistant for organizations that cannot send proprietary code to closed cloud APIs
The Future of ServiceNow and StarCoder
Code models are moving toward agentic workflows where they not only autocomplete but plan, run tests, and fix their own output. StarCoder2, trained on the larger Stack v2 dataset built with Software Heritage, points toward broader language coverage and better data provenance. Expect continued emphasis on transparent training data, opt-out mechanisms, and licensing clarity as legal scrutiny of code-trained models grows, plus tighter integration into enterprise developer platforms.
Putting it into practice
Why it matters
- Vendor strategy. Vendor roadmaps influence what features your team can build next.
- Cost and budget. Commercial terms and deployment options affect long-term cost and risk.
- Risk and safety. Company incentives shape product defaults, safety posture, and openness.
Watch out for
- Launch announcements may outpace stability in real production workflows.
- API pricing or policy shifts can break assumptions overnight.
- Single-vendor dependency increases lock-in and migration costs.
Next steps
- Evaluate providers using your own tasks and datasets.
- Review privacy, security, and legal terms before integration.
- Maintain a fallback plan across models or vendors.
- Monitor release notes so roadmap changes do not surprise teams.

Frequently asked questions
What is ServiceNow and StarCoder?
The original StarCoder models were developed by the BigCode collaboration, co-led by ServiceNow Research and Hugging Face. Their paper documents training data and model capabilities, while the OpenRAIL-M license permits use subject to stated restrictions.
Which two organizations co-led the BigCode project that produced StarCoder?
BigCode was a collaborative effort co-led by ServiceNow Research and Hugging Face to build open, responsibly developed code models.
Which dataset was used for StarCoderBase pretraining?
StarCoderBase was pretrained on The Stack, a large collection of permissively licensed source code.
What training technique lets StarCoder complete code using context on both sides of the cursor?
Fill-in-the-Middle training reorders documents so the model learns to generate a missing span given preceding and following context.
Roughly how large is the flagship StarCoderBase model?
StarCoderBase has about 15.5 billion parameters, modest by frontier standards but strong for its size on code tasks.
Which attention optimization does StarCoder use to reduce memory and speed up inference?
StarCoder uses multi-query attention, sharing key and value projections across heads to cut memory and accelerate long-context inference.
