Apache-2.0, full source public. The library's own README describes itself as unrestricted for enterprise use; Lightning AI's separate Studios platform is hosted compute, not a gated core.

  The fetched body is the full Apache License, Version 2.0 (the standard TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION text through the appendix), with the boilerplate appendix completed as "Copyright [2023] Lightning AI" and "Licensed under the Apache License, Version 2.0 (the "License")".

  The fetched HTML is a client-rendered SPA shell (a boot splash and a bare div#root) with no server-rendered pricing tiers. The page's meta description reads "The all-in-one platform for AI development. Code together. Prototype. Train. Scale. Serve. From your browser - with zero setup.", describing Lightning AI's hosted compute platform rather than any LitGPT-specific feature. Corroborating only; it does not itself settle core-gated.
