Get the right model.
A picker for Cloudflare Workers AI. Tell it the job in plain language — a support agent, a voiceover, semantic search — and it matches your intent to a task, reads your requirements, and ranks the catalog on capability, context, and price.
What's in Workers AI
The full public catalog by task, the price landscape for text generation, and how capabilities are spread across recommendable models.
How Workers AI billing works
Usage is metered in Neurons — $0.011 per 1,000 Neurons, with 10,000 Neurons free every day. The per-model unit prices shown throughout this picker are the USD-equivalent rates Cloudflare publishes for each model, so you can compare directly without converting Neurons yourself.
Compare models
Add 2–4 models from the recommendations or the catalog. Pricing lines keep their own units — per-token, per-tile, per-step and per-minute rates are never flattened into one number.
Browse every model
Search and filter the union of the live API catalog and the Cloudflare docs set. Deprecated models are hidden until you ask for them.
Anthropic & OpenAI model catalog
Every currently available Anthropic and OpenAI model, with pricing, context window, and when to reach for it. Reference only — the recommender above suggests one of these automatically when a task genuinely needs frontier quality. Sending data to any of these means it leaves this Cloudflare account for a third-party API.
effort parameter (typically low / medium / high / xhigh / max, model-dependent — see each card below). OpenAI models expose reasoning.effort (up to none / minimal / low / medium / high / xhigh, also model-dependent). “Ultracode” is not a level of either API — per Anthropic's own docs, it's a Claude Code (the CLI coding agent) session setting that pairs Claude's xhigh effort with standing permission to launch background multi-agent workflows. The API's own effort scale tops out at max.Environment
