Publicly visible does not mean open source
A repository or download may be publicly accessible while granting no general permission to modify or redistribute it. Open-source software comes with a license that grants specific rights and conditions. Read the actual license, not just a badge or the word “open” in a product name. A project may include third-party components under different licenses.
Model weights are a separate question
Open weights means that trained parameters are made available, subject to their license. That does not necessarily include training code, training data or the information needed to reproduce the model. Some model licenses limit use cases or redistribution. Check the license for the exact model version and any accompanying tokenizer, dataset or code. Do not assume one component’s permission covers them all.
Keep a project license record
Before using an asset, record its source URL, version, author, license and any attribution requirements. For modified code, preserve notices where required. Check whether commercial use, redistribution and hosted use are permitted for your intended situation. When terms are unclear, choose a better-documented alternative or get clarification from the owner. This lesson is a practical review habit, not legal advice.
How Atlas labels its resources
The new Atlas Learning Labs are original educational examples released with an MIT license in the download. Existing portfolio downloads are labeled public resources because a source repository and open-source license have not been verified here. That distinction helps you choose between code explicitly offered for reuse and a portfolio item offered for inspection.
Try it yourself
Open the Learning Labs ZIP and locate LICENSE and README.md. Identify the notice you must preserve when redistributing a substantial copy of the code.
What to look for
The MIT license requires the copyright and permission notice to be included in copies or substantial portions of the software. Read the full license supplied with the project.
