gated(the enterprise/ directory ships under the proprietary BerriAI Enterprise License requiring a paid subscription for production use, and the proxy gates premium features on a LITELLM_LICENSE key verified against license.litellm.ai)

An MIT core with a proprietary enterprise directory in the same repository - and the gating is in the code, not merely in BerriAI selling a hosted gateway. The root LICENSE is explicitly split: "All content that resides under the 'enterprise/' directory of this repository, if that directory exists, is licensed under the license defined in 'enterprise/LICENSE'", and everything outside it is MIT. That enterprise license says the software "may only be used in production, if you (and any entity that you represent) have agreed to, and are in compliance with, the BerriAI Subscription Terms of Service ... and otherwise have a valid BerriAI Enterprise license for the correct number of user seats", with copying, distribution and sale forbidden. The directory is not a stub - it ships the enterprise package, hooks, UI and a CloudFormation stack - and the proxy enforces it at runtime, reading a license key from the environment and verifying it against license.litellm.ai before enabling premium features. A license key you must hold for paid features to run is what makes this open core rather than fully open. That is the other side of the line from LangChain, LlamaIndex, Pydantic AI, Zed and Otari, which sell a platform beside a complete open core.

  Root LICENSE body, read rather than assumed. It opens "Portions of this software are licensed as follows:" and then splits the repository in two - "All content that resides under the 'enterprise/' directory of this repository, if that directory exists, is licensed under the license defined in 'enterprise/LICENSE'" and "Content outside of the above mentioned directories or restrictions above is available under the MIT license as defined below", followed by the full MIT text. So the tier-setting license is MIT and the gate is a carve-out named in the license itself.

  The carved-out directory exists and is not a stub. It contains LICENSE.md, README.md, __init__.py, cloudformation_stack, dist, enterprise_hooks, enterprise_ui, litellm_enterprise and its own pyproject.toml - hooks, a UI and a deployment stack, i.e. shipped functionality. The repository license endpoint returns NOASSERTION rather than MIT, which is GitHub declining to classify the split root LICENSE.

  The enterprise license body. It states the software "may only be used in production, if you (and any entity that you represent) have agreed to, and are in compliance with, the BerriAI Subscription Terms of Service ... or other agreement governing the use of the Software, as agreed by you and BerriAI, and otherwise have a valid BerriAI Enterprise license for the correct number of user seats". Copying for development and testing is allowed; "it is forbidden to copy, merge, publish, distribute, sublicense, and/or sell the Software". Production use behind a seat-counted paid license is functionality withheld from the MIT source.

  The enforcement, in code. The module's own header comment is "If litellm license in env, checks if it's valid". LicenseCheck reads a LITELLM_LICENSE environment variable, carries a bundled public_key.pem for air-gapped verification, and otherwise checks the key against base_url https://license.litellm.ai, setting the premium_user flag the proxy tests before serving paid features. A key you must hold for functionality to run, which is the rubric's own wording for a gate.

  Repository root. The published tree is the whole gateway and proxy - litellm, gateway, ui, backend, helm, terraform, docker, migrations, tests - and self-hosting it needs nothing that is not in the repo, so the source dimension is public. Retained from the phase-C pass with a real reading in place of the placeholder.

• https://www.litellm.ai/ recorded 2026-06-04

  Vendor site, kept for context only. It establishes that BerriAI sells a hosted product, which under the settled rule is NOT evidence for or against core-gated and is not what the 4 rests on.
