Terms of use

ModelGuessr is provided free of charge, for fun, with no warranty. By using the site you agree to the following.

Fair play

• Don't spam room creation, prompt suggestions, or arena votes.
• Don't scrape the catalog of answers to train or benchmark.
• Don't submit illegal, hateful, or sexually explicit prompts.
• Don't attempt to abuse the OpenRouter integration (e.g. crafting custom models to exhaust the budget). We cap usage per user and may block abuse.

Content

The LLM answers you see are generated by their respective providers (OpenAI, Anthropic, Google, and others via OpenRouter). Their terms of use apply to that content. Prompts and answers can be inaccurate, offensive, or biased — this is a game, not an oracle.

Availability

The site can be taken down, reset, or changed at any time without notice. Scores and attempts may be wiped if we migrate or reset the database.

Liability

The site is provided “as is”. To the extent allowed by law, we're not liable for damages arising from using — or being unable to use — ModelGuessr.
