What Fireworks AI does

Fireworks AI runs open-source and custom models through serverless per-token APIs, dedicated on-demand GPU deployments and reserved capacity. Teams can also fine-tune models (SFT, DPO, RL) on their own data and deploy each checkpoint to production. It targets AI product teams that need low latency and high throughput, with OpenAI- and Anthropic-compatible endpoints.

How does usedby know who uses Fireworks AI?

Each company is linked to a public page that names it: Fireworks AI's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A company leaves the list only after three checks in a row that no longer find it, and at least 14 days after it was last seen. A company with a published case study or quote is never removed automatically.

What do confirmed, observed and signal mean?

Confirmed (16): a case study, a named quote or a press release. Observed (13): Fireworks AI shows the company on its own pages, for example a logo wall. Signal (0): a job post shows the company’s employees use Fireworks AI, the weakest proof. Every level counts as a customer, and each line shows its level.

How current is this list?

The most recent check was on October 5, 2026, and 29 of 29 companies on this list have been checked so far.
