The news: a 20%+ discount, but only for three months
On Aug. 21, 2026, OpenAI cut API and ChatGPT credit pricing for GPT-5.6 Sol by more than 20%, according to OpenAI’s GPT-5.6 August Updates PDF, with the change also logged by Releasebot’s OpenAI model tracker. The cut runs for three months. It is a promotional window, not a permanent price drop, so treat every dollar figure below as accurate as of Sept. 2, 2026 and subject to change once the promo lapses.
AI visibility vendors, including Temso, Peec AI, Otterly.AI, and Profound, run their prompt-checking engines on model APIs like this one. When the underlying API gets cheaper, a vendor’s cost to run your monitoring plan drops too, at least for as long as the promo lasts.
That connection explains a question buyers ask constantly: why does AI SEO software cost what it costs in the first place?
Why AI SEO software costs what it costs
Prompt monitoring is the core mechanic behind every AI visibility tool on the market. A vendor keeps a list of prompts, the real questions buyers type into an AI engine, and runs each one against every covered engine on a set schedule. Then it logs whether your brand shows up in the answer, where, and who else got mentioned.
That mechanic runs entirely on paid model APIs. Every prompt, on every engine, on every refresh, is a metered call somebody has to pay for. The volume adds up faster than it looks.
| Prompts tracked | Engines checked | Refresh cadence | Queries per cycle | Queries per month |
|---|---|---|---|---|
| 50 | 3 | Weekly | 150 | about 650 |
| 150 | 5 | Weekly | 750 | about 3,250 |
| 400 | 5 | Weekly | 2,000 | about 8,700 |
| 400 | 5 | Daily | 2,000 | about 60,000 |
A 400-prompt set checked across 5 engines runs 2,000 queries every single refresh cycle. Move that cycle from weekly to daily, and the monthly total jumps more than sixfold, from about 8,700 queries to about 60,000.
Multiply that by every customer a vendor runs, and multiply it again for the engines that charge for API access on top of the interface you see. That is the cost floor under every AI SEO subscription. It is also why coverage matters: brand mentions disagree 61.9% of the time between engines like Google AI Overviews, AI Mode, and ChatGPT, per BrightEdge’s AI Catalyst research from July 2025. Checking one engine tells you almost nothing. Checking 5 is the only version of this product worth paying for, and 5 engines cost more to run than one.
No vendor publishes the exact share of its bill that goes to model APIs, so treat the next point as arithmetic, not a leaked number. Cut your single biggest recurring cost line by more than a fifth for a full quarter, and you free up real margin. That is true whether or not a dollar of it reaches your invoice.
As of August 2026: what the tools actually charge
Here is what the entry plans cost, as of Aug. 2026, before any pass-through from the OpenAI promo:
| Tool | Entry plan | Engines at entry | Seats |
|---|---|---|---|
| Temso | $89/mo Starter | 3 engines (all 5 on Growth, $199/mo) | Unlimited on every plan |
| Otterly.AI | $29/mo Lite | 6 platforms, 15 prompts | Plan-based |
| Peec AI | About $90/mo (€85, euro billing) | 3 models on Starter | Unlimited on every plan |
| Profound | $99/mo Starter | ChatGPT only; real multi-engine use starts at $399/mo Growth | Per plan |
None of these four has announced a price change tied to the OpenAI promo as of Sept. 2, 2026. That is not unusual. A three-month discount on one cost input rarely moves a public price list, because vendors do not want to raise it back in November and explain why.
Two of the four charge nothing extra per seat: Temso and Peec AI. That detail matters more than the entry price alone, because it decides what happens to your bill as your team grows, independent of anything OpenAI does with its API. Add a fifth teammate to a per-seat plan and your bill climbs. Add a fifth teammate to Temso’s $89 Starter plan or Peec’s €85 Starter plan, and it does not.
Will vendors pass the savings to you?
A few will, for the length of the promo. A cheaper API bill gives a vendor room to raise a prompt limit, unlock an extra engine at the same price, or hold a price steady that was due to climb. None of that is required, and a discount tied to one model provider, on one line of a much bigger cost stack, is easy for a vendor to absorb quietly instead of announcing.
The window matters more than the discount itself. Three months means the saving disappears around November 2026 unless OpenAI extends it. If a vendor drops its price or expands your limits now, ask what happens to that change when the promo reverts. A temporary perk you lose without warning is worse than no perk at all, because you will have built your workflow around it.
Three questions to ask before you renew
Bring these to your next renewal call, whoever your vendor is.
- Did your prompt limit or engine coverage change in the last billing cycle, and why? A quiet increase tied to a temporary API discount is not the same as a permanent upgrade.
- Is your price locked through your full contract term, or does it reset when the promo ends around November 2026? Get the answer in writing, not in a sales call.
- Does the plan charge per seat, or does the price stay flat as your team grows? This question has nothing to do with OpenAI and everything to do with what you will actually pay in a year. Vendors with unlimited seats on every tier remove the question entirely.
What to expect in November 2026
The promo is time-boxed to three months from Aug. 21, 2026, which points to a reversion around November 2026. When that happens, watch for two things: whether any vendor that quietly expanded limits or held a price steady reverses that change, and whether OpenAI extends, shrinks, or ends the discount entirely.
We will check back once the window closes, and we will refresh the math in our Profound vs Temso vs Peec price breakdown with whatever the API pricing looks like by then.
