fine-tuning — Taking a trained model and training it a bit more on your own examples so it gets better at one specific job.
eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
inference — Running a trained model to get answers — the phase where AI is actually used, as opposed to trained.
Why it matters
An open robotics foundation model now ships with its training data, fine-tuningTaking a trained model and training it a bit more on your own examples so it gets better at one specific job.Full definition → scripts, evalA repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.Full definition → rollouts, and tokenizer recipe, and drops into LeRobot, so adapting it to new hardware no longer means reconstructing the pipeline.
