WizardCoder
Microsoft's open-source code model fine-tuned for superior instruction following on coding tasks.
Overview
WizardCoder is an open-source code language model developed by Microsoft Research that applies the Evol-Instruct technique to fine-tune coding capability. Released in 2023, it achieved state-of-the-art performance on coding benchmarks at the time by evolving coding instructions to be progressively more complex and diverse during training.
The Evol-Instruct approach generates evolved, more difficult versions of simple coding instructions, training the model to handle complex, real-world programming problems rather than simple exercises. WizardCoder consistently outperformed similarly-sized models on HumanEval and HumanEval+ benchmarks, demonstrating that training methodology can be as important as model scale.
Available in 15B, 33B, and 34B parameter sizes based on Code Llama foundations, WizardCoder provides a high-quality open-source option for developers who need instruction-following code generation beyond basic completion. The model is available on Hugging Face and through various inference providers.

WizardCoder is an open-source code-generation model family built on the Evol-Instruct fine-tuning approach, and at release it posted strong coding-benchmark scores that rivalled much larger proprietary models. For researchers and engineers who want a self-hostable, free coding model with no usage fees, it remains a useful baseline and a reference point in the open-weights coding lineage.
It has since been overtaken by newer open coding models, and the project's momentum has cooled, so it is best treated as a known quantity rather than a frontier choice. There is no hosted product or official API; you run the weights yourself, which demands GPU resources and ML literacy. Suited to technical teams comfortable with self-hosting, not to anyone wanting a turnkey assistant.
Notable facts
- WizardCoder's Evol-Instruct technique generates progressively harder coding challenges during training — essentially teaching itself harder problems the same way a student advances through textbooks.
- The 34B version of WizardCoder was the first open-source model to achieve above 70% on HumanEval, a benchmark previously dominated by closed commercial models.
- The WizardLM family (including WizardCoder) was created by a team of 3 researchers at Microsoft, demonstrating that small focused teams can match large lab outputs with smart methodology.
