It supports dynamic batching, model ensembles, concurrent model execution on GPUs and CPUs, and real-time, streaming, and batch inference patterns. Includes Model Analyzer for profiling and Model Navigator for automated optimization.

Local model inference engine with OpenAI-compatible API and web UI

Xinference is a local inference engine that runs LLMs, embedding models, image generation, and audio models with an OpenAI-compatible API. It provides a web dashboard for model management, supports vLLM, llama.cpp, and transformers backends, and handles multi-GPU deployment automatically. Supports 100+ models including Qwen, Llama, Mistral, and DeepSeek with over 9,200 GitHub stars.

GLM Coding Plan by Z.AI — subscription access to GLM-5.3 for agents and IDEs

Z.AI’s GLM Coding Plan is a fixed-quota coding subscription for AI IDEs and coding agents, powered by Zhipu’s GLM-5.3 and GLM-5.3-Flash (not a Kimi plan).

Serverless AI inference for generative media at scale

fal.ai is a serverless AI inference platform providing ultra-low-latency APIs for generating images, videos, audio, and 3D models. With 600+ production-ready models and native Python and JavaScript SDKs, it eliminates GPU management while delivering 30-50% lower costs than alternatives.
