NextTransformer alternatives

Interactive-Active-AI/NextTransformer (391 stars, +189 this week): A comprehensive, cutting-edge open-source framework for next-generation Transformers/LLM, with compute-matched benchmarking and a platform…

Below are 8 other LLM tooling repos tracked by OSS Radar that share at least two GitHub topics about what they do with NextTransformer (platform, language and framework tags don't count), ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
