WhatsMyLLM – AI Model Identifier - Identify Your AI Model in Seconds
WhatsMyLLM is a free, browser-based tool that helps you discover which large language model your AI responses most closely resemble. Instead of relying on a model’s self-description, it compares actual responses to standardized test prompts and identifies the closest match from a bank of 24 AI models, including GPT, Claude, Gemini, Qwen, DeepSeek, and Kimi. Simply copy a test prompt, submit it in a fresh AI chat, and paste the full response into the checker. Add more replies to improve the comparison. With no sign-up required and a browser-local testing workflow, WhatsMyLLM makes AI model identification accessible to curious users, developers, and researchers. Results are statistical matches rather than definitive proof of model identity, helping users understand both the tool’s capabilities and its limitations.
