Dolma toolkit
Allen Institute for AIToolkit for curating language-model pretraining data: built-in taggers (Gopher, C4, OpenWebText), custom taggers, and Rust Bloom-filter deduplication. Runs on a single machine, a cluster, or in the cloud, including S3-compatible storage.
Distinct from the Dolma dataset artifact.

Adoption
2 high confidencePyPI downloads of the dolma package are the usage signal for this tool, counted with mirror traffic as for every PyPI-routed product. Mirrors account for most of this package's downloads, so the figure without them is far lower.

Capability
3 high confidenceThe Dolma toolkit is judged through the corpus it builds, since the toolkit has no benchmark of its own. That corpus scores below RedPajama and RefinedWeb on DataComp-LM, which places the toolkit two tiers below datatrove.
- https://arxiv.org/html/2406.11794v3 recorded 2026-09-29
Table 2 of the DataComp-LM paper compares Dolma-V1 with RedPajama and RefinedWeb at the 7B-1x scale, and the text notes that "all four datasets use various heuristic filters and data cleaning steps" before ranking RefinedWeb first; the table caption adds "Despite not mixing high-quality sources" RefinedWeb performs best, with Dolma-V1 at 35.0 Core and 18.4 Extended below RedPajama and RefinedWeb.
