# Editorial re-verification: Cloudflare AI Playground > Source: > Published: 2026-09-16 21:08:16+00:00 # > Cloudflare AI Playground [playground.ai.cloudflare.com](https://playground.ai.cloudflare.com) The Cloudflare AI Playground at playground.ai.cloudflare.com is a browser environment for experimenting with, benchmarking and tuning AI models, with a Model mode for testing system prompts and run settings, a Compare mode for side-by-side evaluation of models under identical prompts, and an experimental Generative UI mode. It is the front end for models that Cloudflare hosts and serves, and the free access terms come from Workers AI: the free allocation allows anyone to use a total of 10,000 Neurons per day at no charge, with additional usage on the Workers Paid plan billed at $0.011 per 1,000 Neurons. The model catalog covers 65 models including Llama, Qwen, DeepSeek, Kimi, GLM, Gemma, Mistral, Nemotron, Whisper and FLUX families, and the playground itself states that output is unverified and does not reflect Cloudflare's views. No credentials required — anonymous browser sessions over a reverse-engineered cf_agent WebSocket protocol (Playwright transport). ### // pros - Documented free allowance: "Our free allocation allows anyone to use a total of 10,000 Neurons per day at no charge", available on both Free and Paid Workers plans. - No upgrade is required to test models: unlimited-access evaluation happens in the browser, and the Playground's Compare mode benchmarks two models on identical prompts. - Predictable metered pricing beyond the free allocation at $0.011 per 1,000 Neurons, with per-model token and Neuron prices published for each model. - Broad catalog of 65 models including DeepSeek V4, Kimi K2.7/K2.6, GLM-5.2/5.3, Gemma 4, Nemotron 3, gpt-oss, Qwen3.8, Whisper and FLUX image models. - Backed by a large public infrastructure provider with documented rate limits (for example 300 requests/minute for text generation and 3000/minute for embeddings) rather than an undocumented free tier. ### // cons - The free allocation is a hard daily cap: above 10,000 Neurons per day the only option is the Workers Paid plan, and all limits reset daily at 00:00 UTC, so unused allowance is lost. - Frontier models are throttled on standard billing at 20 requests per minute per account per model; the 50 requests/minute limit requires prepaid AI Gateway credits and unified billing. - Modeled licensing is third-party: the playground page points to third-party licenses, so model weights and terms are not Cloudflare's. - The playground is explicitly a non-production surface: the page states output is unverified and does not reflect Cloudflare's views, and use is governed by Cloudflare's website terms and privacy policy. - Real application use requires moving to Workers AI bindings or the Cloudflare API, which means adding Workers, Pages or API plumbing rather than just using the playground. Use the Playground to pick and benchmark models before writing code, and use the 10,000 Neurons/day free allocation for low-volume prototypes and evaluation. Move to Workers AI bindings or the Cloudflare API when you deploy, and add prepaid AI Gateway credits if you need frontier-model throughput above 20 requests/minute. imported analysis — independent third party, not Uprouter editorial · verify before relying on it Value taken from the provider’s own published free-tier terms, expressed in USD. note: Free allocation is stated as 10,000 Neurons per day at no charge on the Workers AI pricing page, equivalent to about $0.11/day at the published rate of $0.011 per 1,000 Neurons (the dollar figure is a conversion, the allowance is official). | Plan | Type | Monthly | Input /1M | Output /1M | Note | |---|---|---|---|---|---| | Workers AI free tier | free | — | — | — | Free monthly inference allotment; overage billed per operation. | [official pricing page](https://developers.cloudflare.com/workers-ai/platform/pricing/) Pricing normalized from public sources — always verify with the provider. ### // model prices | Model | Input /1M | Output /1M | Context | |---|---|---|---| | [gpt-oss-120b](https://www.uprouter.online/models/gpt-oss-120b) | — | — | 131k | | [gpt-oss:20b](https://www.uprouter.online/models/gpt-oss-20b) | — | — | 131k | | [Qwen3.8 27B](https://www.uprouter.online/models/qwen/qwen3.8-27b) | — | — | 1M | | [Gemma 4 26B A4B](https://www.uprouter.online/models/google/gemma-4-26b-a4b-it) | — | — | 262k | | [Llama 4 Scout](https://www.uprouter.online/models/llama-4-scout) | — | — | 1.3M | | [Nemotron 3 Super](https://www.uprouter.online/models/nvidia/nemotron-3-super-120b-a12b) | — | — | 262k | | [glm-5.3](https://www.uprouter.online/models/glm-5-3) | — | — | 1.3M | | [DeepSeek V4 Pro 0813](https://www.uprouter.online/models/deepseek/deepseek-v4-pro-0813) | — | — | 1.0M | | [Kimi K2.7 Code](https://www.uprouter.online/models/kimi-k2-7-code) | — | — | 262k | ## $ Does Cloudflare AI Playground have a free tier? Yes — Cloudflare AI Playground offers a free tier that we value at roughly $0.11 in free credits. Always confirm current limits on Cloudflare AI Playground's official pricing page — free tiers change without notice. ## $ How much does Cloudflare AI Playground cost per 1M tokens? Cloudflare AI Playground does not publish simple per-1M-token pricing (it may bill per request, per output, or via a subscription plan). Check their official pricing page for exact figures. ## $ Is Cloudflare AI Playground safe to use? Uprouter rates Cloudflare AI Playground as medium risk. Risk is low. The operator is Cloudflare, a large publicly traded infrastructure company, so there is no meaningful abandonment or identity risk, and the free allowance is documented on the official pricing page with a clear daily reset and a published overage rate of $0.011 per 1,000 Neurons. The cost exposure is bounded and transparent: exceeding 10,000 Neurons per day fails rather than silently billing, and paid usage requires an explicit plan upgrade. Data considerations are the usual platform terms - the playground runs under Cloudflare's website terms and privacy policy, and outputs are labelled unverified - while the models themselves carry third-party licences. The only practical caveats are that the free allowance does not accumulate and that frontier-model rate limits are modest without prepaid credits. Risk ratings are editorial, evidence-based, and never influenced by affiliate relationships. ## $ Can I use Cloudflare AI Playground through Uprouter Connect? Cloudflare AI Playground is not marked Connect-compatible in our catalog yet. You can still use their API directly, or request compatibility via /submit. Raw community sentiment, shown unblended. Votes never feed into objective data fields like price, risk, or status — and never into sort order.

The operator is Cloudflare, a large publicly traded infrastructure company, so there is no meaningful abandonment or identity risk, and the free allowance is documented on the official pricing page with a clear daily reset and a published overage rate of $0.011 per 1,000 Neurons.

The only practical caveats are that the free allowance does not accumulate and that frontier-model rate limits are modest without prepaid credits. Confidence reflects how much verifiable evidence (official docs, probe history, community reports) backs this entry. Risk is our editorial assessment of operator reliability and terms — not financial advice. ### code_snippets ``` # Cloudflare AI Playground's own API — get a key from their dashboard curl https://api.cloudflare.com/client/v4/{account_id}/ai/v1/chat/completions/chat/completions \ -H "Authorization: Bearer THEIR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "gpt-oss-120b", "messages": [{ "role": "user", "content": "Hello" }] }' ``` Direct to the provider — Uprouter receives nothing; verify their current pricing before purchasing.
