OpenRouter vs Groq (2026): Model Router or Fast Inference Provider?

By Hisham · Published · Facts as of Oct 30, 2026, each linked to its source.

OpenRouter and Groq are often compared, but they are different kinds of product. Groq is an inference provider that runs models on its own hardware. OpenRouter is a router and marketplace in front of many providers, and Groq is one of them.

So the real question is whether you want a single fast provider with its own account and limits, or one API across many providers. The table below compares what each one documents, with sources.

OpenRouter vs Groq at a glance

As of Oct 30, 2026OpenRouterGroq
What it isA model marketplace and router: one account and one API for 600+ models from 80+ providers. [source]An inference provider: it runs models on its own LPU-based inference cloud and sells API access to them. [source]
APIOpenAI-compatible: change the base URL and model names to migrate. [source]Mostly OpenAI-compatible at https://api.groq.com/openai/v1; logprobs, logit_bias, top_logprobs, messages[].name and n > 1 are not supported. [source]
Groq modelsLists Groq as a provider, with 8 models served by Groq on its provider page. [source]Its own catalog of hosted models (for example openai/gpt-oss-120b, openai/gpt-oss-20b, qwen/qwen3.8-27b and Whisper speech models). [source]
How you payPrepaid credits; each request deducts its cost at the provider's list price. No markup on provider pricing. [source]Billed monthly in arrears for tokens used, with progressive billing thresholds for new Developer accounts. [source]
Payment methodsStandard and Business: credit and debit cards, AliPay and crypto (USDC). Enterprise: invoicing and purchase orders. [source]Credit cards (Visa, Mastercard, American Express, Discover), US bank accounts and SEPA debit accounts. [source]
Plans5.5% on credit purchases (Standard) or 8% (Business), charged when you buy credits, never per request. [source]A Free tier and a pay-as-you-go Developer tier; upgrading needs a payment method and unlocks higher limits, Batch and Flex processing and spend limits. [source]
Rate limitsNo plan-based rate limit on paid models: limits come from the provider, apart from DDoS protection on very high bursts. [source]Per-model RPM, RPD, TPM and TPD limits, applied per organization; your exact limits are on the Limits page in the console. [source]
When you hit a 429Provider routing with automatic fallback to other providers for the same model, optional fallback models, and an auto router (openrouter/auto) that adds no fee. [source]A 429 carries retry-after (seconds); x-ratelimit-* headers report remaining requests (per day) and tokens (per minute). [source]

When to pick OpenRouter

  • You want many models and providers behind one API and one balance, including some Groq-served models.
  • You want fallback to another provider when one rate limits you, handled by the router.
  • You do not want separate provider accounts or monthly invoices from each provider.

When to pick Groq

  • You want Groq-hosted models directly, with Groq's own limits, Batch and Flex processing, and spend limits on the Developer tier.
  • You want to be billed by Groq directly, with monthly invoices paid by card, US bank account or SEPA debit.
  • Your app uses one or two models that Groq hosts and you would rather not add a router in between.

Where SentioGate fits

If you want Groq's speed with fallback, a BYOK router sits between the two: add your own Groq key and an OpenRouter key (or other provider keys) to SentioGate, send model "auto", and a Groq 429 is retried on your next key or the next-cheapest qualifying model. Groq bills you directly for Groq traffic, at 0% token markup from SentioGate.

FAQ

Is Groq the same as OpenRouter?

No. Groq is an inference provider that runs models on its own LPU-based cloud. OpenRouter is a router and marketplace across 80+ providers, and it lists Groq as one of them.

Can I use Groq models through OpenRouter?

Yes. OpenRouter lists Groq as a provider, with 8 models served by Groq on its Groq provider page (as of Oct 30, 2026). Requests are billed through your OpenRouter credits.

How do Groq rate limits work?

Groq applies per-model limits on requests and tokens per minute and per day, at the organization level. Exact limits are on the Limits page in the Groq console; a 429 response carries a retry-after header in seconds, and cached tokens do not count toward the limits.

Is Groq OpenAI-compatible?

Mostly. Groq's OpenAI-compatible base URL is https://api.groq.com/openai/v1. Its docs list a few unsupported fields: logprobs, logit_bias, top_logprobs, messages[].name and n greater than 1.
