AI Visibility Model Prices
Section titled “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 23 August 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 3.7 Flash (default) | latest | 3 | €0.06 |
| Gemini | Gemini 3.6 Flash | prior | 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 + 3 + 6 = 11 credits (€0.22). The Gemini and Grok defaults cost more because live search/grounding can dominate provider cost.
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
Section titled “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.
