About
EmpirioLabs AI is specialized AI model hosting for open, proprietary, and custom stacks. We run open-source models on GPU infrastructure we manage, serve optimized endpoints for proprietary models, and help teams deploy their own models to real users. The catalog spans text, image, video, audio, transcription, embedding, reranking, research, and 3D models, with a browser playground, GPU Cloud instances, and hosted AI agents.
It comes with live per-model pricing, a REST API, a remote MCP server for Claude, ChatGPT, and code editors, and integrations for LangChain, LiteLLM, Dify, n8n, and VS Code. New models and features are available as they launch.

About
RankGPT is a Python toolkit designed to explore the use of generative Large Language Models (LLMs) like ChatGPT and GPT-4 for relevance ranking in Information Retrieval (IR). It introduces methods such as instructional permutation generation and a sliding window strategy to enable LLMs to effectively rerank documents. It supports various LLMs, including GPT-3.5, GPT-4, Claude, Cohere, and Llama2 via LiteLLM. RankGPT provides modules for retrieval, reranking, evaluation, and response analysis, facilitating end-to-end workflows. It includes a module for detailed analysis of input prompts and LLM responses, addressing reliability concerns with LLM APIs and non-deterministic behavior in Mixture-of-Experts (MoE) models. The toolkit supports various backends, including SGLang and TensorRT-LLM, and is compatible with a wide range of LLMs. RankGPT's Model Zoo includes models like LiT5 and MonoT5, hosted on Hugging Face.
