OGX
MetaOpen agentic API server from Meta, launched as Llama Stack in 2024 and rebranded in 2026 as OGX. It is not an inference engine: it composes and routes to inference backends such as vLLM, Ollama and Bedrock, alongside vector stores, safety, tools and file storage, behind OpenAI- and Anthropic-compatible APIs, with unified interfaces for agents, fine-tuning and evaluation.
The rebrand carried continuous commit history across the rename, so this is the same project rather than a fork.

renamed from Llama Stack; model-agnostic, multi-SDK, routes to inference backends rather than serving weights itself
Adoption
2 low confidenceGitHub stars are the only usage signal for OGX; the project publishes no download or usage figure. Stars alone cannot place this higher, because a star reflects attention rather than use, and OGX's recent rename from Llama Stack further muddles any historical comparison.

Capability
3 medium confidenceOGX composes many inference providers, plus vector store, safety, tool and file backends, behind OpenAI, Anthropic and Responses API surfaces. It runs no forward pass itself, so its capability here reflects gateway and agentic-server breadth rather than inference throughput.
