Fireworks AI free tier

What Fireworks AI publishes about its free allowance, which models it covers, and how to point an existing tool at it.

What Fireworks AI's free tier allows

An account with no payment method and no credits is limited to 10 requests per minute across the entire account. Adding a payment method and active credits raises the ceiling to a maximum of 6,000 RPM. Fireworks is pre-paid, so the 10 RPM envelope is the only no-cost path and there is no published daily request cap on it.

The 10 RPM limit is a request-rate envelope, not a free token grant; serverless token throughput still depends on your spending tier.

Checking a Fireworks AI key

The CORS preflight allows any origin to send an Authorization header, so a browser can call this endpoint directly. That was measured against https://api.fireworks.ai on 2026-07-25.

So a key can be checked in the browser checker without installing anything. If you would rather not paste a key into a web page, this does the same thing:

#!/usr/bin/env sh
set -eu

: "${FIREWORKS_API_KEY:?Set FIREWORKS_API_KEY to a key you created yourself at the provider console}"

# Prints the models this key can reach, then the HTTP status on its own line so
# 200, 401, and 429 stay distinguishable.
curl --silent --show-error \
  --write-out '\nHTTP %{http_code}\n' \
  --header "Authorization: Bearer $FIREWORKS_API_KEY" \
  'https://api.fireworks.ai/inference/v1/models'

Using a Fireworks AI key

Fireworks AI serves the OpenAI chat completions protocol at https://api.fireworks.ai/inference/v1. Point any client that accepts a custom base URL at it, and let the client read the key from FIREWORKS_API_KEY so the value never lands in a config file:

# Merge this snippet into ~/.codex/config.toml.
# Project-level config cannot select a custom model provider.
model = "accounts/fireworks/models/llama-v3p3-70b-instruct"
model_provider = "fireworks"

[model_providers.fireworks]
name = "Fireworks AI OpenAI-compatible gateway"
base_url = "https://api.fireworks.ai/inference/v1"
env_key = "FIREWORKS_API_KEY"
wire_api = "responses"

Questions about the Fireworks AI free tier

Does Fireworks AI ask for a credit card?

No. Fireworks AI is one of 23 providers here that hand out free access without a card, so the only cost of trying it is the signup.

What are Fireworks AI's free-tier rate limits?

Fireworks AI publishes 10 requests per minute. Those are the numbers in its own documentation as reviewed on 2026-07-25.

What happens when a Fireworks AI key hits the limit?

The endpoint answers 429. That is a statement about the request that was refused, not about how much quota is left; only a reset header from the provider tells you when it clears.

Is the Fireworks AI free tier going away?

Nothing in Fireworks AI's own documentation says so as of 2026-07-25. The 10 RPM limit is a request-rate envelope, not a free token grant; serverless token throughput still depends on your spending tier.

Can Fireworks AI be used with Codex, Cline, or Continue?

Yes. Fireworks AI serves the OpenAI chat completions protocol at https://api.fireworks.ai/inference/v1, so any client that accepts a custom base URL can use it. Claude Code is the exception, because it speaks the Anthropic protocol instead.
