The July 23, 2026 announcement presents The Stack v3 as an open dataset containing about 5 trillion tokens of deduplicated and filtered source code, spanning 713 languages. The publication says code under restrictive licenses is excluded. For engineers training code models, its scale and language coverage may provide a basis for evaluating a larger dataset.
To check these claims, consult the original publication and dataset documentation, reviewing how deduplication, filtering, and license criteria are defined. If you use AI to study or apply the material, avoid submitting proprietary code, credentials, or personal data; also verify code rights and usage terms before incorporating code into a project.
