Standard Intelligence

Standard Intelligence (si.inc) is an aligned AGI research lab based in San Francisco building AI models that explore and learn like humans do. Its work includes hertz-dev, an open-source 8.5B-parameter autoregressive base model for interactive, full-duplex conversational audio; a fully general computer-action model that navigates websites, executes CAD sequences, and drives autonomously at 30 FPS; and The Heap, a 30-petabyte data-storage system built in San Francisco for under $500,000. The company has raised $75M from Sequoia and Spark Capital. It publishes research posts and open-source code on GitHub but does not currently expose a public developer API.

Standard Intelligence is profiled on the APIs.io network. Tagged areas include Company, Ai, AGI, Artificial Intelligence, and Machine Learning.

Standard Intelligence’s developer surface includes engineering blog and 3 more developer resources.
