AI Visibility Model Prices

Every AI Visibility model has its own per-probe price, set by what the model costs to run. A run’s cost is the sum of its probes’ prices. Each platform has one default model, used when a run does not name one; default prices range from 1 to 6 credits.

Prices as of 24 July 2026:

Platform	Model	Tier	Credits per probe	Price
Perplexity	Sonar (default)	standard	1	€0.02
Perplexity	Sonar Pro	latest	3	€0.06
OpenAI	GPT-5.4 mini (default)	standard	1	€0.02
OpenAI	GPT-5.4 nano	lite	1	€0.02
OpenAI	GPT-5.6 Luna	lite	2	€0.04
OpenAI	GPT-5.4	prior	4	€0.08
OpenAI	GPT-5.6 Terra	latest	6	€0.12
OpenAI	GPT-5.5	latest	12	€0.24
OpenAI	GPT-5.6 Sol	latest	15	€0.30
Grok	Grok 4.3 (default)	latest	6	€0.12
Grok	Grok 4.20	prior	6	€0.12
Gemini	Gemini 3.6 Flash (default)	latest	2	€0.04
Gemini	Gemini 3.5 Flash	prior	2	€0.04
Gemini	Gemini 2.5 Flash	prior	2	€0.04
Gemini	Gemini 3.1 Flash Lite	lite	1	€0.02
Gemini	Gemini 3.5 Flash Lite	lite	1	€0.02

A default run across all four platforms costs 1 + 1 + 2 + 6 = 10 credits (€0.20). The Grok default costs more because Grok bills for live search on top of the model.

Price is set per model, not per tier: two models on the same tier can cost different amounts. Read price from the model, not its tier badge.

The table above is a snapshot. The selectable set and prices can change, so List visibility models is the source of truth: it returns the exact credits_per_probe for every current option. Price a run from that endpoint rather than assuming a fixed rate.

How Credits Are Handled

Sleepwalker checks the required credit balance before starting billable work.

Completed work is recorded in the credit ledger. If a request cannot be started, credits are not charged. If credits are reserved for a probe or one-off action and no usable result is produced, the reservation is released.

See Credit Lifecycle for estimated, reserved, settled, released, and failed states.
