What is IN THE WEIGHTS?

IN THE WEIGHTS is an interactive platform created by independent developers Thomas Dimson and Joey Flynn. It visualizes the billions of numerical values (weights) that make up an AI model, allowing users to explore and understand neural networks. The tool lets you search for specific names to see if they "live on" inside models like GPT-5.5, GPT-5.4 Mini, Opus 4.8, Haiku 4.5, Grok 4.20, Gemini 3.1 Lite, Kimi K2 0905, DeepSeek V4, Llama 3.3 70B, Llama 3.2 1B, GLM 4.7 Flash, Mistral 3.2 24B, and Qwen3 8B. It also displays a leaderboard of "Today's Heavyweights" ranked by strength score.

Application scenarios

  • AI research and education

    Students and researchers can visually explore how neural networks encode real-world knowledge, such as famous people or fictional characters.

  • Public curiosity and engagement

    Anyone curious about AI can search for their own name or a celebrity to see if the model "knows" them and how strongly.

  • Model comparison

    Users can compare how different AI models (e.g., GPT-5.5 vs. Llama 3.3 70B) represent the same person or concept.

  • Data journalism and storytelling

    Journalists can use the platform to illustrate how AI training data reflects cultural prominence or bias.

  • Personal discovery

    Individuals can check whether they or their favorite public figures are embedded in the weights of major language models.

Core Features

  • Name search

    Enter any name to find out if that person or entity is represented in the weights of supported AI models.

  • Strength scoring

    Each entry receives a numerical "strength" value (e.g., 990 for John Coltrane) indicating how strongly the model encodes that concept.

  • Today's Heavyweights leaderboard

    A daily-updated list of the top-ranked names by strength, showing the most prominent figures in the model's knowledge.

  • Multi-model support

    The platform covers a wide range of models including GPT-5.5, GPT-5.4 Mini, Opus 4.8, Haiku 4.5, Grok 4.20, Gemini 3.1 Lite, Kimi K2 0905, DeepSeek V4, Llama 3.3 70B, Llama 3.2 1B, GLM 4.7 Flash, Mistral 3.2 24B, and Qwen3 8B.

  • Visual avatars

    Each entry is accompanied by a profile image, making the data more engaging and human-readable.

  • Individual profile pages

    Clicking on a name takes you to a dedicated page (e.g., `/p/john-coltrane`) with more details about that specific entry.

Target users

IN THE WEIGHTS is designed for anyone curious about how AI models store knowledge—from AI researchers and students to journalists, data enthusiasts, and the general public. It's particularly useful for those who want a tangible, visual way to understand what a neural network "knows" about the world.

How to use IN THE WEIGHTS?

  1. Open the website at intheweights.com.
  2. Enter a name in the search box and click the "x" button to submit.
  3. View the result showing whether that name is present in the model's weights and its strength score.
  4. Browse the "Today's Heavyweights" leaderboard to see the top-ranked names.
  5. Click on any name to visit its dedicated profile page for more details.

Effect review

IN THE WEIGHTS offers a genuinely novel way to peek inside the black box of AI models. The strength scoring and leaderboard make abstract neural network weights feel concrete and comparable. While the platform doesn't provide deep technical analysis, it succeeds brilliantly at making AI interpretability accessible to a non-technical audience. The inclusion of multiple major models adds significant value for comparison. For anyone who's wondered what an AI actually "knows," this tool delivers a satisfying, visual answer.
