Order depends on listed price for your volume only. No provider pays for its position.

Input volume includes the cached share, not an additional token volume. This is a list-price estimate, not a quote: cache-write charges, cache eligibility/TTL, batch discounts, long-context surcharges, regional pricing and taxes are excluded. Check the provider's terms for your workload before switching.

Before you pick a provider

DeepInfra lists GLM-5.3 22% below the developer's own API (Z.ai) on a blended basis. Check rate limits, data retention and model quantization before switching.

Context windows differ by provider, from 1M to 1M tokens. A cheaper host may not accept your longest prompts.

11 of 12 providers list a cached-input price. Repeated system prompts or documents can cost much less there than the standard input rate shown above.
