What each one is

The product in its own terms, so the numbers below have context.

ReOpenly

ReOpenly is an end-to-end platform that handles the infrastructure and training pipeline for fine-tuning open-source models on your dataset, then serving them via hosted API or downloading the weights for self-deployment. Smaller models tuned to specific tasks achieve comparable accuracy to large generalist models at significantly lower cost.
