Pricing & access accuracy: Anthropic Claude prices are sourced from Anthropic's official model reference. Other providers' prices are indicative list prices. The License and Free access columns are a general guide — free tiers, trial credits and rate limits change frequently and vary by region and account tier. Always confirm against each provider's live pricing page before budgeting. Edit the MODELS array in this file to keep the index current.
