    A limited set of compound adjectives most related to specific phrases like laid-back, sold-out, grown-up (second term is often direction or spatial).

    FAQ
    What's AI Interpretability?
    Today, hundreds of millions of people are using AIs like ChatGPT, but nobody, not even the engineers that created them, knows exactly how they think, or how to reliably steer them to not be harmful to humans. This is because modern AIs were created through a process similar to evolution, using extremely powerful computers. Understanding how AIs think is the field of interpretability, and steering them is alignment. Both are important for AI safety.
    AI safety? Are you trying to take away my GPUs?
    No. We want to help understand and align extremely powerful AI, since there is no guarantee that the AI will be friendly to humanity.
    Why Neuronpedia?
    The goal of Neuronpedia is to be the "Wikipedia for AI Interpretability". But why is this needed?
    • Automatic Frontend for Your Data: Researchers are busy enough doing research. They shouldn't have to scramble together a frontend to make their work presentable/usable before publishing their paper. Neuronpedia wants to make publishing your interpretability research as easy as clicking Upload.
    • One Central, Standardized, Searchable Database: Interpretability researchers have usually created their own custom websites to upload and display their data. For example, OpenAI's Neuron Viewer and Neel Nanda's Neuroscope have similar types of data, but totally different interfaces, APIs, and data structures. Neuronpedia is the free and open website where all the interpretability data can be uploaded, searched, compared, linked to, exported, tested, etc.
    • Crowdsourcing and Peer Testing: Neuronpedia is used by (and created by!) people who are fascinated by AI interpretability. Neuronpedia's tools and game allow anyone to contribute to explaining, verifying, and analyzing your data. Someone might even find interesting things in your data that you didn't notice! (And vice versa.)
    Who does Neuronpedia benefit?
    If AI alignment goes well, then Neuronpedia benefits everyone. But most immediately, Neuronpedia benefits interpretability researchers and those who are curious about the inner workings of AI models. As a project that's mostly supported by short-term grants from nonprofits, Neuronpedia is also committed to openness and does not sell data - all data uploaded and contributed is free to use. If you'd like a specific data export, please contact us.
    Do you support directions/features?
    Yes, we do - including support for browsing, viewing, testing, and uploading directions/features. We currently have directions from OpenAI, Joseph Bloom, and Cunningham et al.
    Who are you?
    Neuronpedia is created by Johnny Lin - I'm an ex-Apple engineer who previously founded a privacy startup. AI is fascinating - and the impact it will have should not be underestimated.
    How can I help?
    • Researchers: Use Neuronpedia for your models and directions. Email us and let us know what would be the most useful features for you. APIs? New ways to test neurons? New visualizations? Plugins?
    • Everyone Else: Poke around AI brains. Find cool and interesting neurons. Comment and star them.
    • The Wealthy: Donate to Neuronpedia - don't make us put up a Jimmy Wales-style banner at the top of every neuron.
    Game
    The Neuronpedia game (crowdsourced understanding of AI) is currently less actively maintained, as we are focused on building out research features.
