What it DID ship was a device-side Python SDK ("lt_sdk", distributed on PyPI as lightelligence-sdk) that compiled and ran models on the company's optical processing unit, documented on Read the Docs. That entire distribution has been withdrawn: the PyPI project, the Read the Docs project and the Lightelligence/SDKDocs GitHub repository all now return 404 while the public SDKExamples repository that depends on them is still online and still instructs users to install them. This is a decayed developer program, not an absent one. packages: - language: python registry: pypi name: lightelligence-sdk url: https://pypi.org/project/lightelligence-sdk/ install: pip install lightelligence-sdk official: true status: withdrawn version: null published: null last_referenced_version: 0.1.15 note: >- version/published are null because the package no longer exists on PyPI — https://pypi.org/simple/lightelligence-sdk/ returned 404 on 2026-08-25 against a control probe of https://pypi.org/simple/requests/ that returned 200, so the 404 is authoritative and not a bot challenge. last_referenced_version 0.1.15 is the pin still recorded in https://raw.githubusercontent.com/Lightelligence/SDKExamples/master/requirements.txt, the company's own public example repository; it is the last version the provider is known to have published, NOT a version currently installable. docs: https://lightelligence-sdk.readthedocs.io/en/latest/index.html docs_status: 404 docs_note: >- Read the Docs answers "Project not found"; readthedocs.org/api/v3/projects/lightelligence-sdk/ returns {"detail":"No Project matches the given query."}. The source repository the SDK docs pointed at, https://github.com/Lightelligence/SDKDocs, returns 404 via the GitHub API. - language: python registry: pypi name: model-vis url: https://pypi.org/project/model-vis/ install: pip install model-vis official: true status: published version: 0.0.22 published: '2020-08-17' source_code: https://github.com/Lightelligence/model_vis kind: tool note: >- Interactive graph visualization for ML models, not an API client. Attribution rests on an exact match: the PyPI latest version (0.0.22, uploaded 2020-08-17, read from https://pypi.org/simple/model-vis/) equals the version declared in setup.py in the Lightelligence GitHub organization's own model_vis repository, whose README instructs "pip install model-vis". The PyPI upload carries a personal author_email rather than a company address, so the publisher is an individual at the company rather than a company account.

They are not published by Shanghai Xizhi Technology Co., Ltd. / Lightelligence the photonic computing company profiled here, and were deliberately not recorded as this provider's packages. registries_probed: - {registry: pypi, result: 1 live package (model-vis), 1 withdrawn (lightelligence-sdk)} - {registry: npm, result: none first-party — only the same-name LEDVANCE scope, excluded above} - {registry: rubygems, result: not probed — no Ruby surface published} - {registry: crates.io, result: not probed — no Rust surface published} - {registry: maven, result: not probed — no JVM surface published} - {registry: nuget, result: not probed — no .NET surface published} - {registry: go, result: not probed — no Go surface published}
