| Free tier | 10,000 Neurons a day per account on Workers Free unit credits; metered on request-count; counted in Neurons, Cloudflare's way of measuring AI outputs across models by the GPU compute a request needs; Workers Paid bills usage above the allocation at USD 0.011 per 1,000 Neurons. What one Neuron buys differs by model: bge-reranker-base is priced at 283 neurons per M input tokens. Prepaid AI Gateway credits can also pay for Workers AI inference and are not the unit of this allowance |

| 2026-10-30 | developers.cloudflare.com/workers-ai/platform/pricing/ | the allocation is counted in Neurons, priced at USD 0.011 per 1,000 above 10,000 a day |
| 2026-10-30 | developers.cloudflare.com/workers-ai/platform/pricing/ | the daily allocation resets at 00:00 UTC and operations fail once it is spent |
| 2026-10-30 | developers.cloudflare.com/workers-ai/platform/limits/ | Text Classification models run at 2000 requests a minute; Text Generation at 300 a minute |

| 2026-10-30 | developers.cloudflare.com/fundamentals/account/create-accoun | a Cloudflare account is made with an email and a password, followed by an email verification |
| 2026-10-30 | developers.cloudflare.com/workers-ai/platform/pricing/ | Workers Free carries 10,000 Neurons a day; more needs Workers Paid at USD 0.011 per 1,000 Neurons |
| 2026-10-30 | developers.cloudflare.com/workers-ai/models/bge-reranker-bas | bge-reranker-base is a Text Classification model |
| 2026-10-30 | developers.cloudflare.com/workers/platform/pricing/ | Workers Free is the default plan of an account |
| 2026-11-01 | developers.cloudflare.com/workers-ai/platform/pricing/ | a Neuron is Cloudflare's own measure of the GPU compute that a request needs |
| 2026-11-01 | developers.cloudflare.com/workers-ai/platform/pricing/ | the page prices bge-reranker-base at 283 neurons per million input tokens |
| 2026-11-01 | developers.cloudflare.com/workers-ai/platform/errors/ | the daily free allocation of 10,000 neurons is an account-level limit: spending it answers HTTP 429 with internal code 3036, named Account limited |
| 2026-11-01 | developers.cloudflare.com/changelog/post/2025-02-20-updated- | each model's tokens, audio seconds or images map to Neurons, so a Neuron is one unit over several raw units |
| 2026-11-01 | developers.cloudflare.com/ai-gateway/features/unified-billin | prepaid AI Gateway credits can pay for Workers AI inference, a payment route apart from the Neuron allocation |
| 2026-11-01 | developers.cloudflare.com/workers-ai/platform/pricing/ | Workers Free carries 10,000 Neurons a day; usage beyond it needs an upgrade to Workers Paid |
