Lumino AI

Lumino AI is a managed platform for fine tuning open source large language models. Users sign up on the Lumino dashboard, generate an API key, and submit fine tuning jobs on a base model of their choice without having to provision or manage the training infrastructure themselves. The documentation describes the platform as aimed at AI researchers, developers and enthusiasts who want to customize open models for a specific task or domain. Access is available through the web dashboard and through an SDK that reads an API key from an environment variable, with an API reference covering the programmatic endpoints. Sign up works with an email address and password or a Google account. Fine tuning is priced per job and published openly. The price is based on a dataset of 1 million tokens and one epoch. For Llama 3.1 8B it is $2 whether the method is qLoRA, LoRA or full fine tuning. For Llama 3.1 70B it is $10 for either LoRA or full fine tuning. Larger datasets and more epochs scale the cost accordingly. The listing points at the Lumino documentation site rather than a marketing page, so the product is best understood as a developer tool for teams who already know which open model they want to adapt and need a straightforward way to run the training.
