# oumi vs wandb

*GraphCanon updated Aug 23, 2026*

## Verdict

Pick oumi if oumi is a tool for fine-tuning, evaluating, and deploying open-source large language models (LLMs) such as Gemma 4, Qwen3.5, Qwen3.6, gpt-oss, DeepSeek-R1, among others; pick wandb if wandb excels in streamlined experiment tracking and model versioning across multiple machine learning frameworks.

[oumi](https://oumi.ai) reports 9.4k GitHub stars, 784 forks, and 34 open issues, last pushed Aug 21, 2026. [wandb](https://wandb.ai) has 11k stars, 880 forks, and 906 open issues, last pushed Aug 3, 2026. Figures are from public GitHub metadata via [oumi's repository](https://github.com/oumi-ai/oumi) and [wandb's repository](https://github.com/wandb/wandb).

## Choose when

### Choose oumi if…

- License: oumi is Apache-2.0, wandb is MIT.
- Requirements: Requires Docker; Docker is used for standardized and portable environment deployments..
- Tags unique to oumi: dpo, evaluation, fine-tuning, llms.
- Also covers Inference & Serving.
- oumi ships Docker support for self-hosted deployment.
- - You are working specifically with one of the supported open-source LLMs including Gemma 4 or Qwen variants.

### Choose wandb if…

- License: wandb is MIT, oumi is Apache-2.0.
- Tags unique to wandb: ai, collaboration, deep-learning, hyperparameter-optimization.
- Need extensive collaboration features for teams working on deep-learning projects

## When NOT to use oumi

- - If your focus is on proprietary models rather than open-source ones, Oumi may not offer the necessary support or integrations.
- - You require deployment flexibility beyond what Oumi provides for less commonly supported open-source LLMs outside its primary focus (e.g., Gemma 4, Qwen series).

## When NOT to use wandb

- Looking for a lightweight solution without extensive collaboration features
- Focusing on simple models where detailed experiment tracking is unnecessary
- Operating within environments that strictly forbid third-party hosting solutions
