See the comparison table for live GitHub stats and shared categories. ### When should I choose accelerate over openpi? Choose accelerate over openpi when Tags unique to accelerate: deepspeed, fsdp, mixed precision, pytorch; Easy mixed-precision support for PyTorch models; More recently updated (last pushed Sep 25, 2026). ### When should I choose openpi over accelerate? Choose openpi over accelerate when Requirements: The repository requires an NVIDIA GPU with at least 8 GB of memory for inference, 22.5 GB for fine-tuning with LoRA, and 70 GB for full fine-tuning.; Tags unique to openpi: fine-tuning, gpu, inference, lora; Use openpi when you need to run AI models with precise GPU memory requirements for inference and fine-tuning, particularly with LoRA and full fine-tuning modes. ### When should I avoid accelerate? Non-PyTorch projects do not benefit from this tool Doesnt offer advanced auto-tuning features for other frameworks like TensorFlow Limited to Python environments compatible with PyTorch 1.10.0+ ### When should I avoid openpi? Avoid using openpi if your project requires multi-node training, as the current training script does not support this feature. Do not use openpi if you are working on an operating system other than Ubuntu 22.04, as the repository has not been tested with other systems. ### Is accelerate or openpi more popular on GitHub? openpi has more GitHub stars (13,874 vs 9,885). Stars measure visibility, not whether either tool fits your constraints. ### Are accelerate and openpi open source? Yes - both are open-source projects on GitHub (accelerate: Apache-2.0, openpi: Apache-2.0). ### Where can I find alternatives to accelerate or openpi? GraphCanon lists graph-backed alternatives at [accelerate alternatives](/tools/huggingface-accelerate/alternatives) and [openpi alternatives](/tools/physical-intelligence-openpi/alternatives) ([accelerate markdown twin](/tools/huggingface-accelerate/alternatives.md), [openpi markdown twin](/tools/physical-intelligence-openpi/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/huggingface-accelerate-vs-physical-intelligence-openpi.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, accelerate or openpi? accelerate: Very active. openpi: Active. 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 accelerate and openpi? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [accelerate trust report](/tools/huggingface-accelerate/trust); [openpi trust report](/tools/physical-intelligence-openpi/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=huggingface-accelerate`](/api/graphcanon/graph?tool=huggingface-accelerate) - 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/_
