What is Forefront?
Forefront is a developer platform for working with open-source AI models. It lets you pick a leading open-source model, customize it with your private data, check how it performs on a validation set, and then serve it through a serverless API. The site also includes a Datasets section where production data can be piped in and stored as ready-to-fine-tune training and validation files, plus an Inspector for reviewing samples and token distributions.
In practice you can fine-tune models for a specific use case, watch training loss charts, run built-in evals such as MMLU, TruthfulQA and HumanEval, and test models in a Playground before calling the API with a few lines of code. Models can also be exported for self-hosting or imported from Hugging Face. Forefront states that it does not log requests or use customer data for training.
