Fireworks AI gives new accounts a $1 one-time signup credit rather than an ongoing free tier. The free plan includes access to serverless inference with $1 in free credits.

About

Fireworks AI is a cloud platform for running, tuning, and deploying generative AI models. It provides serverless inference, on-demand GPU deployments, and fine-tuning workflows for open models, with model access exposed through an API and developer tooling.

The pricing page lists $1 in free credits for serverless inference, along with per-token pricing for text and vision models, per-second pricing for speech-to-text, per-step and per-image pricing for image generation, and per-GPU-hour pricing for on-demand deployments. It is aimed at developers building code assistants, chatbots, RAG systems, multimodal apps, and other model-backed applications.

This free tier includes a one-time $1 credit for serverless inference, so it has real value but only as a small starter allowance rather than a recurring monthly entitlement. Because the credit is capped and does not repeat each month, it is not meaningful to convert it into a monthly value; the practical value is just the one dollar of usage it unlocks, with no indication that a credit card is unnecessary.
