Models & Pricing

8 AI models across 3 providers. Pay per token with USDC credits.

​

Available models

All prices are per 1 million tokens (USD). Cost = input tokens + output tokens at the rates below.

Pricing is always available live at GET /ai/models. If there is ever a discrepancy between this page and the API response, the API is the source of truth.

Model ID	Provider	Display Name	Input / 1M tokens	Output / 1M tokens	Best for
gpt-4o-mini	OpenAI	GPT-4o Mini	$0.21	$0.84	Cheapest. Simple tasks, high volume.
gemini-flash	Google	Gemini 2.5 Flash	$0.42	$3.50	Fast, good quality, low cost.
gpt-4.1-mini	OpenAI	GPT-4.1 Mini	$0.56	$2.24	Better reasoning at low cost.
haiku	Anthropic	Claude Haiku 4.5	$1.40	$7.00	Default. Best reasoning-to-cost ratio.
gemini-pro	Google	Gemini 2.5 Pro	$1.75	$14.00	Strong reasoning. 2 RPM free-tier limit.
gpt-4.1	OpenAI	GPT-4.1	$2.80	$11.20	High quality, fast.
gpt-4o	OpenAI	GPT-4o	$3.50	$14.00	Multimodal, proven.
sonnet	Anthropic	Claude Sonnet 4.5	$4.20	$21.00	Premium. Best quality, highest cost.

Start with gpt-4o-mini for prototyping ($0.21/1M input). Switch to haiku or sonnet for production quality.

Rate limits

Model	Provider RPM	Max output tokens
gpt-4o-mini	30,000	16,384
gpt-4.1-mini	10,000	16,384
gpt-4.1	10,000	32,768
gpt-4o	10,000	16,384
haiku	4,000	8,192
sonnet	1,000	8,192
gemini-flash	15 (free tier)	8,192
gemini-pro	2 (free tier)	8,192

Your org’s API key also has a per-key rate limit (default: 1,000 RPM). The effective limit is the lower of the two.

Google Gemini models are on the free tier (low RPM). For production use at scale, prefer OpenAI or Anthropic models. gemini-pro in particular is rate-limited to 2 RPM — fine for occasional reasoning calls, not production traffic.
