petals vs vllm

Common questions

What is the difference between petals and vllm?

petals: Run LLMs at home, BitTorrent-style. vllm: Easy, fast, and cheap LLM serving for everyone. See the comparison table for live GitHub stats and shared categories.

When should I choose petals over vllm?

Choose petals over vllm when License: petals is MIT, vllm is Apache-2.0; VLLM aims to serve LLM inference easily, fast, and cheap by optimizing the model serving. Petals also optimizes for speed but through a distributed computing approach using BitTorrent-style protocols; Tags unique to petals: deep-learning, falcon, language-models, guanaco; Also covers LLM Frameworks; petals ships Docker support for self-hosted deployment.

When should I choose vllm over petals?

Choose vllm over petals when License: vllm is Apache-2.0, petals is MIT; VLLM aims to serve LLM inference easily, fast, and cheap by optimizing the model serving. Petals also optimizes for speed but through a distributed computing approach using BitTorrent-style protocols; Tags unique to vllm: amd, llama, deepseek, cuda; - When you need state-of-the-art throughput with efficient attention management using **PagedAttention**.

When should I avoid petals?

Last GitHub push was 669 days ago (dormant maintenance, Sep 7, 2024). Validate activity before betting a new project on petals. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

When should I avoid vllm?

- For users who do not require or cannot support the hardware and software dependencies such as CUDA/HIP for optimal performance. - If your project focuses on model training rather than inference since vLLM's primary strength lies in serving and high-throughput applications. - When you need a tool that is highly portable to older or less common architectures, given its optimization for modern GPUs and specialized hardware might not be beneficial in those scenarios.

Is petals or vllm more popular on GitHub?

vllm has more GitHub stars (85,665 vs 10,269). Stars measure visibility, not whether either tool fits your constraints.

Are petals and vllm open source?

Yes - both are open-source projects on GitHub (petals: MIT, vllm: Apache-2.0).
