1. BentoML
The easiest way to serve AI apps and models - Build Model Inference APIs, Job queues, LLM apps, Multi-model pipelines, and more!
What sets it apart: Unified model serving framework with Bento packaging — turn any model into a production API with automatic Docker, adaptive batching, and multi-model orchestration
Best for: Teams deploying ML/AI models as production APIs; Applications needing dynamic batching and GPU optimization; Multi-model inference pipelines (LLM + embedding + reranker)
2. Ray
Ray is an AI compute engine. Ray consists of a core distributed runtime and a set of AI Libraries for accelerating ML workloads.
What sets it apart: vs Spark: Python-native with actor model and ML-specific libraries (Train/Tune/Serve); vs Dask: broader AI/ML ecosystem with RLlib, serving, and managed Anyscale platform
Best for: Scaling ML training and serving across clusters; Distributed hyperparameter tuning; Building scalable AI inference pipelines
3. vLLM
A high-throughput and memory-efficient inference and serving engine for LLMs
What sets it apart: Unlike llama.cpp (consumer-hardware focused, C++ native), vLLM is the production throughput king with PagedAttention achieving 2-24x higher throughput than HuggingFace Transformers on datacenter GPUs
Best for: Production LLM serving requiring maximum throughput with PagedAttention and continuous batching; Teams serving multiple LoRA adapters from a single base model in production
4. OpenLLM
Run any open-source LLMs, such as DeepSeek and Llama, as OpenAI compatible API endpoint in the cloud.
What sets it apart: Unlike Ollama which focuses on local/desktop usage, OpenLLM bridges local development and cloud production through unified BentoML tooling — providing the same CLI workflow from laptop to Kubernetes cluster with OpenAI API compatibility
Best for: Teams wanting the fastest path from model selection to OpenAI-compatible API endpoint; DevOps engineers deploying open-source LLMs to production with Docker/Kubernetes
5. Text Generation Inference
Large Language Model Text Generation Inference
What sets it apart: Battle-tested in production at Hugging Face (powers HuggingChat and Inference API) — now in maintenance mode with recommendation to use vLLM/SGLang, but remains the reference implementation for optimized LLM serving with the broadest hardware support
Best for: Production LLM serving with HuggingFace models at scale; Teams needing OpenAI-compatible API for open-source models
6. llama-cpp-python
Python bindings for llama.cpp
What sets it apart: vs vLLM: optimized for local/edge deployment with GGUF quantized models on consumer hardware; vs Ollama: programmatic Python API with LangChain/LlamaIndex integration rather than CLI-first approach
Best for: Running LLMs locally with Python; Building OpenAI-compatible local inference servers; Prototyping with quantized models on consumer hardware
7. FastAgency
The fastest way to bring multi-agent workflows to production.
What sets it apart: vs raw AutoGen/AG2: production deployment framework with unified interface, built-in testing, and FastAPI/NATS.io adapters for scaling agent workflows
Best for: Teams deploying AG2/AutoGen workflows to production; Projects needing unified console + web interfaces for agent workflows
8. Agno
Build, run, manage agentic software at scale.
What sets it apart: Production-first agent runtime with built-in session isolation, approval workflows, and scalable FastAPI serving — unlike LangChain which is framework-first
Best for: Production multi-agent systems with session isolation; Enterprise agentic applications needing approval workflows and audit trails
