Estimated cost

Input per pass

≈ 6,181

Output (expected answers)

≈ 1,603

Input + expected answers. Providers' public standard prices (Mistral AI, DeepSeek, OpenAI, Anthropic) converted from USD to euros at the ECB rate, checked on October 13, 2026. Batch: Batch API (OpenAI, Anthropic, Mistral) or off-peak hours (DeepSeek). Estimate: 1 token ≈ 3.6 characters.

Fine-tuning (LoRA on a rented GPU)

Tokens per training epoch

≈ 7,784

For 3 epochs

≈ 23,352

A small dataset trains in a few minutes: 1 hour billed at minimum. APIs publish no usable training price (OpenAI is closing fine-tuning to new customers, Mistral quotes on request): the estimate uses GPU rental, prices excluding VAT as of October 13, 2026.
