Description
Workers AI is Cloudflare's serverless AI inference platform that lets developers run machine learning models globally with a single API call. Built on Cloudflare's network spanning more than 200 cities worldwide, the platform eliminates the need to manage GPUs, plan capacity, or operate orchestration layers. Developers simply call any model from their code and Workers AI handles provisioning, scaling, and latency optimization automatically.
The platform offers a catalog of more than 50 ready-to-use models covering large language models, image generation, speech-to-text, and vector embeddings. Models are accessible through a simple unified endpoint that is fully compatible with OpenAI SDKs and standard REST APIs, allowing teams to integrate Workers AI into existing workflows without rewriting their tooling. An interactive AI Playground is available for testing and prototyping models before deployment.
Workers AI uses a neuron-based pay-per-inference pricing model with no idle costs. The free tier provides 10,000 neurons per day, while the paid tier is priced at $0.011 per thousand neurons. Because GPU utilization for inference workloads averages only 20 to 40 percent in traditional setups, the serverless model allows customers to avoid paying for unused hardware capacity.
The platform integrates natively with other Cloudflare developer primitives including Vectorize for vector search, AI Gateway for observability, and Workers for compute — enabling complete AI application stacks without leaving the Cloudflare ecosystem. Use cases span LLM-powered applications, real-time audio transcription, semantic search, image generation pipelines, and AI agent workflows built on stateful infrastructure.
