[torchtune](https://pytorch.org/torchtune/main/) reports 5.8k GitHub stars, 735 forks, and 445 open issues, last pushed Jul 10, 2026. [aeneas](http://www.readbeyond.it/aeneas/) has 2.8k stars, 276 forks, and 75 open issues, last pushed Jun 22, 2024. Figures are from public GitHub metadata via [torchtune's repository](https://github.com/meta-pytorch/torchtune) and [aeneas's repository](https://github.com/readbeyond/aeneas). | | [torchtune](/tools/meta-pytorch-torchtune.md) | [aeneas](/tools/readbeyond-aeneas.md) | | --- | --- | --- | | Tagline | PyTorch native post-training library | aeneas is a Python/C library and a set of tools to automagically synchronize audio and text (aka forced alignment) | | Stars | 5,782 | 2,849 | | Forks | 735 | 276 | | Open issues | 445 | 75 | | Language | Python | Python | | Adopt for | - | - | | Persona | - | - | | Runtime | - | - | | License | BSD-3-Clause | AGPL-3.0 | | Categories | LLM Frameworks, Model Training, Inference & Serving | Speech & Audio, Developer Tools | ## Trust and health _Sourced signals - not a safety guarantee.

Validate activity before betting a new project on aeneas. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between torchtune and aeneas? torchtune: PyTorch native post-training library. aeneas: aeneas is a Python/C library and a set of tools to automagically synchronize audio and text (aka forced alignment). See the comparison table for live GitHub stats and shared categories. ### When should I choose torchtune over aeneas? Choose torchtune over aeneas when License: torchtune is BSD-3-Clause, aeneas is AGPL-3.0; Tags unique to torchtune: python; Also covers LLM Frameworks, Model Training, Inference & Serving. ### When should I choose aeneas over torchtune? Choose aeneas over torchtune when License: aeneas is AGPL-3.0, torchtune is BSD-3-Clause; Tags unique to aeneas: espeak, ffmpeg, alignment, espeak-ng; Also covers Speech & Audio, Developer Tools. ### When should I avoid torchtune? LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ### When should I avoid aeneas? Last GitHub push was 750 days ago (dormant maintenance, Jun 22, 2024). Validate activity before betting a new project on aeneas. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ### Is torchtune or aeneas more popular on GitHub? torchtune has more GitHub stars (5,782 vs 2,849). Stars measure visibility, not whether either tool fits your constraints. ### Are torchtune and aeneas open source? Yes - both are open-source projects on GitHub (torchtune: BSD-3-Clause, aeneas: AGPL-3.0). ### Where can I find alternatives to torchtune or aeneas? GraphCanon lists graph-backed alternatives at [torchtune alternatives](/tools/meta-pytorch-torchtune/alternatives) and [aeneas alternatives](/tools/readbeyond-aeneas/alternatives) ([torchtune markdown twin](/tools/meta-pytorch-torchtune/alternatives.md), [aeneas markdown twin](/tools/readbeyond-aeneas/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/meta-pytorch-torchtune-vs-readbeyond-aeneas.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, torchtune or aeneas? torchtune: Very active. aeneas: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for torchtune and aeneas? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [torchtune trust report](/tools/meta-pytorch-torchtune/trust); [aeneas trust report](/tools/readbeyond-aeneas/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=meta-pytorch-torchtune`](/api/graphcanon/graph?tool=meta-pytorch-torchtune) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
