About Forefront
Forefront is a web and API platform designed for developers and technical teams that need to fine-tune and deploy open-source language models using proprietary data. The platform provides tools for uploading and managing custom datasets for training and validation, along with built-in evaluation metrics such as MMLU, TruthfulQA, MT-Bench, ARC, and HumanEval. Users can access inference via API endpoints for chat and completion, as well as a Playground for testing models before integration. Team collaboration features include multi-member support with role-based access controls. Forefront emphasizes open-source model customization without requiring teams to build and maintain GPU infrastructure from scratch, and it supports exporting models for self-hosting or use with other providers. The platform operates on a subscription model with usage-based token fees, offering a free tier with limited features and paid plans for teams and enterprises with expanded capabilities.
