FAQ

Which AI models are supported?

We currently support OpenAI GPT-4 and GPT-3.5, Anthropic Claude 3 (Opus, Sonnet, Haiku), and Google Gemini Pro. More models are added regularly.

Do I need my own API keys?

Yes — you bring your own API keys for each provider. This keeps your data private and ensures you pay providers directly at their standard rates.

How is "quality" measured?

Quality scores are computed using a combination of automated metrics (BLEU, semantic similarity) and optional human ratings you provide. You can also define custom rubrics.
