AI model pricing changes frequently. Help us keep the directory accurate.

Known outdated entries (verify and fix):

• GPT-4o — verify current input/output pricing
• Claude Haiku 3.5 — verify current pricing
• Gemini 2.5 Flash — verify current pricing
• Mistral Large 2 — verify current pricing

How to contribute:

1. Check the official provider pricing page
2. If the price in prisma/seed.ts is wrong, open a PR updating it
3. PR title: [update] <Model Name> — pricing
4. Include the source URL in the PR description

Even opening an issue with the correct value + source link is helpful.
