OpenRouter says it passes provider inference prices through, but charges a platform fee when customers buy credits: its pricing page lists 5.5% for Standard and 8% for Business. Direct access avoids that credit-purchase fee, but your total depends on the exact model, provider, token mix, service tier, region and payment arrangement. To identify the lower-cost route, compare both against the same workload and current prices.
What OpenRouter’s fees mean
OpenRouter says it passes through provider inference pricing rather than adding a token-price markup. Its support page describes provider-rate pricing alongside a unified API and automatic fallbacks (OpenRouter Support). Separately, OpenRouter’s pricing page lists a 5.5% Standard platform fee and an 8% Business platform fee; its Business page says the fee applies to credit purchases, not inference (pricing; Business pricing).

For a basic prepaid-credit comparison, account for the applicable fee when buying OpenRouter credits. Do not treat that fee as a per-token inference markup: those are different parts of the cost. The published fees were shown on OpenRouter’s pricing pages as accessed October 7, 2026, and should be checked again before budgeting because prices and plan terms can change.

With direct access, you pay the provider under its own pricing and payment terms, without OpenRouter’s credit-purchase platform fee. That does not prove direct access is cheaper in every case: the provider’s rates can vary by model, token type, context length, processing mode and region, and an OpenRouter route must be matched to the same provider and conditions to make a fair comparison.
#1 Best Overall
For example, OpenAI lists separate rates for standard input, cached input, cache writes and output, and distinguishes some context lengths and service modes (OpenAI API pricing). Google’s Gemini Developer API page varies prices by model and service tier and lists charges for extras such as grounding (Gemini API pricing). Anthropic’s list prices, effective May 27, 2026, distinguish standard global, US-only and batch rates, as well as token-cache prices (Anthropic list prices).
How to make an apples-to-apples comparison
- Match the model and provider. Select the same exact model and, where OpenRouter can route it to multiple providers, identify or pin the same provider. Model and provider availability can change; check the current options in OpenRouter’s quickstart documentation.
- Describe your actual workload. Estimate input and output tokens, cached-token volume, context length, request count, and any tool or grounding calls. Use the provider’s applicable rates for each component rather than comparing only headline input prices.
- Match operating conditions. Compare the same service mode, such as standard, batch or priority, and the same region where applicable. These conditions affect published rates for some providers.
- Add the route-specific charges. Include OpenRouter’s current credit-purchase fee for the relevant plan. For direct access, use the provider’s invoice terms and account for any applicable service-specific charges.
- Compare totals and operations separately. OpenRouter documents a unified endpoint and automatic fallbacks, which may simplify integration or routing. The documentation does not assign a dollar saving to those features; decide whether they are valuable for your system rather than assuming they make the API route cheaper.
How to evaluate OpenRouter BYOK
Bring Your Own Key (BYOK) uses provider credentials, so provider-side costs and rate limits remain relevant. OpenRouter’s current pricing page describes a 5% fee after a plan-dependent monthly allowance, measured against list-price inference; the allowance and its terms depend on the account plan. OpenRouter’s BYOK documentation likewise describes the fee and says BYOK gives customers control over provider-side costs and limits (BYOK documentation).
To compare BYOK with direct access, add the provider invoice and any OpenRouter fee that applies after your account’s allowance. Check the live pricing page and your plan rather than assuming that all accounts have the same allowance or that BYOK is automatically fee-free. OpenRouter’s pricing page is the relevant current reference for allowances; the BYOK documentation may not reflect the latest plan terms.

- Choose direct access for a cost comparison when you want to avoid OpenRouter’s credit-purchase fee and are prepared to manage provider-specific credentials and integrations. Confirm that the provider’s rate for your actual token mix and service conditions is lower overall.
- Consider OpenRouter when a unified API or automatic fallback behavior suits your integration needs. Its published inference pricing is provider-rate pass-through, but include the applicable platform fee when comparing prepaid credits.
- Evaluate BYOK on its own terms when you want OpenRouter’s API layer with provider credentials. Calculate provider charges plus any fee beyond the current plan allowance.
These are pricing mechanics, not results from an independent market-wide test. Without a specified model, workload and account plan, there is no supported universal winner.
