Key Points

  • Tahuna is a minimalist, CLI-first “control plane” aimed at making post-training workflows (e.g., orchestration and compute/resource management) less painful for AI/ML researchers and engineers.
  • The tool sits between a local environment and a compute provider, while letting users fully own the training loop details such as rollout logic, rewards/rubrics, and data pipelines.
  • Tahuna is positioned to handle the supporting “plumbing” around post-training, rather than replacing core user logic.
  • The project is cleaning up its code and plans to open-source the entire stack soon, currently being free to use in an early stage.
  • The maintainers are inviting experimentation and contributions, especially adapters, and are open to discussion of implementation tradeoffs.

We have been exploring a project around post-training infrastructure, a minimalist tool that does one thing really well:
Make post-training a little less painful by equipping Researchers, AI/ML engineers & Tinkerers with a gentle control plane. Post-training models tends to introduce a new axis of complexity - the orchestration and compute ressource management - alongside defining your own training loop, your rewards & rubrics, managing the parallel training.

Tahuna is CLI-first, it sits between your local environment and your compute provider. You own the training loop entirely - your rollout logic, your rewards, your data pipeline. It handles the plumbing around it.

We are cleaning up the code, but we are open-sourcing the entire stack soon.

Free to use. Early stage, looking for people who want to poke at it, break it, or contribute adapters.

Happy to talk implementation details or tradeoffs in the comments.
