What is Forefront?

Forefront is a platform for developers who want to build with open-source AI models. It gives you a familiar experience similar to leading closed-source platforms, but with more control and transparency. You can fine-tune models on your private data, evaluate their performance, and run them via an API.

To get started, you choose a model and customize it with your data. Forefront provides built-in loss charts and validation sets so you can watch your model learn and improve. You can test your model in the Playground before integrating it with the API. The platform also lets you export models to self-host or use another provider.

Forefront also acts as a data warehouse for your AI data. You can store training, validation, and evaluation datasets in one place. It supports importing from HuggingFace and piping production data into ready-to-fine-tune datasets. This suits developers who want to own their models and data without relying on closed-source providers.

Forefront features

  • Fine-tuning: Customize leading open-source models with your private data for any use case.
  • Evaluation: Run automatic evals like MMLU and TruthfulQA to assess model performance.
  • Serverless API: Run models with a few lines of code using chat or completion endpoints.
  • Data storage: Store all your training, validation, and evaluation data in one place.
  • Model export: Export your fine-tuned models to self-host or host with another provider.

What you can do with Forefront

  • Fine-tune a model on your customer support conversations for better responses.
  • Evaluate a fine-tuned model against standard benchmarks before deployment.
  • Store production data from your app to build a dataset for future fine-tuning.
  • Import a model from HuggingFace and run inference without loading it into Colab.

How to get started with Forefront

  1. Sign up for free on Forefront's website.
  2. Choose a model and fine-tune it with your private data.
  3. Test your model in the Playground, then integrate the API into your app.

Tips for better results with Forefront

  • Start with a small validation set before fine-tuning on your full dataset to catch issues early and watch the loss charts for signs of overfitting.
  • Use Forefront's built-in evals like MMLU and TruthfulQA to compare your fine-tuned model against benchmarks, then adjust your training data based on the results.
  • Test your model in the Playground before integrating the API to verify responses match your expectations and to refine prompts without incurring API costs.
  • Store production data through Forefront's pipeline to build a dataset for future fine-tuning, so you can continuously improve your model as you gather more examples.

Forefront pricing

Forefront has a free way to start, with paid plans for heavier use. Check forefront.ai for current limits and prices.

What to check before you rely on Forefront

  • Check whether the free tier includes API access and fine-tuning, since the website lists freemium pricing but does not state specific limits or quotas.
  • Verify what data storage and export formats are supported, as the website mentions data warehousing but does not list export file types or retention policies.
  • Confirm that your model's license allows commercial use and self-hosting, since Forefront supports exporting models but the website does not detail licensing terms.
