Show HN: Are You in the Weights?

Points and comments are a snapshot, not live.

A Show HN tool checks if your name appears in the training data of 12 AI models.

In the Weights (intheweights.com) lets users enter a name and see how 12 AI models, including GPT-5.5, Claude Opus 4.8, Gemini 3.1 Lite, and DeepSeek V4, describe that person. Results include a 'strength' score (0–996) and a leaderboard of top names like Mozart and Shakespeare. The tool classifies some results as likely hallucinations, especially those supported only by smaller models. It uses a consistent prompt asking models to return JSON with resolved names, confidence scores, and snippets. Pixel portraits are generated by GPT-5.4 Image 2.

What commenters are saying

Many commenters found themselves misidentified: one was called a Scottish soccer player, another a folk metal musician, and another a German football goalkeeper. Some users with unique names reported accurate matches. The creator explained that the hallucination classifier prioritizes recall over precision, often flagging results supported only by small models. Several commenters noted that their real names were matched to different real people with the same name, not fabrications. The tool hit rate limits due to front-page traffic; pagination on the 'latest' leaderboard was disabled in response.
