Lightmatter

Lightmatter is a Mountain View, California photonic supercomputer company building optical interconnect and compute products for AI infrastructure. Its flagship Passage line of 3D-stacked photonic interposers and co-packaged optics, including the Passage M1000 superchip and the Passage L20 and L200 pluggables, deliver up to 114 Tbps of optical bandwidth and target frontier-scale AI training and inference fabrics. Lightmatter also ships the Envise general-purpose photonic AI accelerator and the Guide VLSP Light Engine universal light source, and provides reference systems and evaluation kits. The company holds a 4.4 billion dollar valuation on roughly 850 million dollars raised as of late 2024 and partners with TSMC, GlobalFoundries, OIF, IEEE, and OCP. Lightmatter does not expose a public developer API, so this profile is hardware-, research-, and press-focused with an intentionally empty apis list.

Lightmatter is profiled on the APIs.io network. Tagged areas include AI Hardware, Photonics, Interconnect, Accelerator, and Optical.

Lightmatter’s developer surface includes engineering blog and 13 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/lightmatter: open an issue to ask a question, or submit a pull request to add artifacts.
