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, Artificial Intelligence, AGI, Machine-Learning, and Foundation Models.

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

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/standard-intelligence: open an issue to ask a question, or submit a pull request to add artifacts.
