description: 'Lightelligence (legal entity Shanghai Xizhi Technology Co., Ltd. / 曦智科技, founded 2017 as an MIT spin-out) builds
  optoelectronic hybrid computing hardware — photonic accelerators and optical interconnect fabric for AI and high-performance
  computing. Its product line is physical: the PACE 2 optoelectronic accelerated computing card (a PCIe Gen4 x16 accelerator
  built around a 128x128 optical matrix multiplier), the Gazelle optical computing evaluation board, the Photowave CXL optical
  interconnect, and the Lightsphere X distributed optical circuit switch, supported by the company''s oMAC, oNOC and oNET
  optical core, network-on-chip and inter-chip network technologies. The software surface is a device-side stack — ONNX, OpenCL,
  PyTorch and TVM support plus a Python SDK (lt_sdk) that compiled and ran models on the optical processing unit — not a web
  API. As of this profile the company publishes no public web API, no OpenAPI/AsyncAPI/GraphQL contract, and no developer
  portal; the lightelligence-sdk package and its Read the Docs reference have both been withdrawn. Its remaining public developer-facing
  surface is a GitHub organization of chip design and verification tooling (Bazel Verilog build rules, RTL/UVM linters, the
  yis interface-spec generator) and an Optical Computing Developer Community of research cases and papers.'

  reason: no-developer-program
  detail: Lightelligence sells optoelectronic hardware (PCIe accelerator cards, optical switches) with no hosted API at all,
    and the one developer program it did run has been taken down — the lightelligence-sdk PyPI package, its Read the Docs
    reference and the Lightelligence/SDKDocs repository all 404 while the company's own public SDKExamples repo still tells
    users to install them.
