Groq vs Fireworks AI

The question that decides it: Do you need maximum output speed on a handful of models, or a broad open-weight menu with a business associate agreement?

Our verdict

Regulated data, fine-tuning, or a model that is not on a short list: Fireworks AI, which states around 100 models and will sign a HIPAA business associate agreement. Raw output speed on a small set of open-weight models, where EU residency is not a requirement: Groq.

Why

Start with what these are. Neither is a gateway — both are inference providers that serve open-weight models on their own stacks, and they appear in this catalog because teams routinely use one as the routing layer itself rather than putting a gateway in front of it. Both are managed-only, both bundle inference into the token price, and neither has a separable gateway fee to compare. That means the usual markup and credit-fee questions do not apply; you are comparing per-token rates and what surrounds them.

The reach difference is stark and it is the first filter. Fireworks states around 100 models. Groq's catalog gives between 6 and 16 depending on which kinds you count, and that is the deliberate consequence of its design: a narrow menu is what makes running models on its own LPU hardware viable. If the model you need is not on Groq's list, the speed argument never gets made.

Compliance separates them more sharply than most pairs at this end of the catalog. Both publish a SOC 2 report and both state zero data retention with a retention figure of zero days, which is a genuinely strong answer from either. But Fireworks will sign a HIPAA business associate agreement and Groq does not publish one, and Groq explicitly records EU data residency as not offered — one of very few outright noes in this catalog rather than an unpublished field. For a European team or a regulated workload, that pair of facts decides it.

The training question splits the other way, and it is the one place Fireworks is weaker. Fireworks states it trains on customer data only if you opt in, which is a clear and acceptable answer. Groq does not publish a position on training at all, which is recorded as unpublished rather than as a no. Both log metadata only with a documented off switch. Fireworks also offers fine-tuning and dedicated deployments, which is a category of capability Groq's narrow-menu model does not cover.

Which one, concretely

Choose Groq if

  • Output speed on open-weight models is the primary requirement
  • The model you need is on a short list you have already checked
  • You want zero stated retention and metadata-only logging
  • EU data residency is not a requirement

Choose Fireworks AI if

  • You need a signed HIPAA business associate agreement
  • You need a broad open-weight menu — around 100 models
  • You need fine-tuning or dedicated deployments
  • You want an explicit opt-in-only position on training

What catches people out

Side by side

4 of 13 fields differ, marked with a dot. Every figure links to the vendor page it came from. Blank values read Not published rather than No — silence from a vendor is not a negative answer.

Common questions

Are Groq and Fireworks AI gateways?

No. Both are inference providers that serve open-weight models on their own infrastructure. They appear in this catalog because teams often use one directly as the routing layer instead of putting a gateway in front of it. Neither gives you multi-provider failover, which is the main thing a gateway adds.

Which one can I use with health data?

Fireworks AI, which will sign a HIPAA business associate agreement. Groq does not publish one — recorded as unpublished rather than a refusal, so it is worth asking. Both publish a SOC 2 report and state zero data retention with a retention figure of zero days, so the gap is specifically the BAA.

How many models does each one serve?

Fireworks AI states around 100. Groq's catalog gives between 6 and 16 depending on which kinds you include, because a narrow menu is what makes its own hardware viable. Check that the specific model you need is served by Groq before weighing any speed advantage, since reach is the binding constraint.
