How Much Do ChatGPT Ads Cost in Thailand? CPM, CPC & Budgets Explained (2026)

ChatGPT Ads in Thailand have no fixed price. You set your own budget and bids in OpenAI Ads Manager, and you pay either per 1,000 impressions (CPM) or per valid click (CPC). Campaigns that optimise for leads or sales are still billed by impression or by click, never per conversion. For ad accounts billed in Thai baht, OpenAI's minimum daily budget is 33 THB, and a daily budget works as a seven-day average rather than a hard daily cap.

This guide walks through each billing option, how budgets are paced, when your card is charged, and how to plan a first budget for a Thai business. Every rule and figure below comes from OpenAI's own Help Center. If you would rather have the account built and run for you, our ChatGPT Ads agency team in Bangkok handles the whole process.

How does ChatGPT Ads pricing work?

ChatGPT Ads are sold through an auction. OpenAI describes it as a relevance-weighted, second-price auction: your bid matters, and so does how relevant your ad is to the conversation it would appear under. There is no rate card. The price you pay is set by the auction each time your ad is shown or clicked.

Three settings shape what you spend: the campaign objective, which decides how you are billed; the maximum bid you set for each ad group; and the budget you set for each campaign. Ads appear below ChatGPT's responses with your business name, logo, a title, a short description, an image and a link to your landing page.

It also helps to know who you are paying to reach. According to OpenAI's overview of ads in ChatGPT, ads are not shown to users on Plus, Pro or any Business plan, or to accounts identified as belonging to people under 18. Your budget goes toward other eligible users, such as people on the Free and Go plans.

What billing options do ChatGPT Ads offer: CPM, CPC or conversions?

Your campaign objective decides how you are billed. Ads Manager currently offers three objectives:

Views (CPM): you pay per 1,000 impressions served. Use it for awareness, such as launching a new branch or a new service.
Clicks (CPC): you pay per valid click. Use it when you want qualified visitors on a specific landing page.
Conversions: delivery is optimised toward one standard conversion event you choose, such as a submitted lead or a completed order. You then choose to be billed per valid click (oCPC) or per 1,000 impressions (oCPM).

The detail many advertisers miss is that the Conversions objective does not mean paying per lead. OpenAI's billing guide states that ads are not billed per conversion. With click billing you pay for valid clicks, with impression billing you pay for impressions, and your cost per conversion is whatever the auction produces. You work it out by dividing spend by conversions.

The Conversions objective also needs working conversion tracking before you can use it, through the OpenAI Pixel, the Conversions API or both, and it only accepts standard events such as a lead or an order, not custom events. Impression billing for conversion campaigns is in beta, with access expanding across accounts.

Choose the objective before you launch

You cannot switch a live campaign to a different objective. A new objective means a new campaign, or for a conversion campaign, a clone with the other billing option. The conversion event you pick for a conversion campaign is locked as well. Decide what you are paying for before the campaign goes live.

What is the minimum budget for ChatGPT Ads in Thailand?

OpenAI sets a minimum daily budget for each billing currency. In the Minimum Campaign Spend table, the minimum for accounts billed in Thai baht is 33 THB per day. The US minimum, for comparison, is 25 USD. Your billing currency is fixed when you create the ad account, so a Thai company should open its account in THB from the start.

The minimum is a floor, not a recommendation. A second rule matters more in practice: if a campaign uses a daily budget with a fixed bid, the daily budget must be at least as high as the highest effective bid in that campaign. A campaign cannot have a daily budget lower than a single bid it is prepared to pay.

For click campaigns, OpenAI's guidance is to start with a maximum bid of 3 to 5 USD per click. Ads Manager also shows bid-strength guidance that tells you whether a bid is likely to be competitive or likely to limit delivery. For conversion campaigns, OpenAI gives no recommended bid, so you set a bid cap and adjust it from real results.

How does the 7-day budget averaging work?

A daily budget in ChatGPT Ads is the average amount you want to spend per day across a seven-day period. It is a delivery target, not a same-day spending limit. OpenAI's daily budget rules apply two caps:

On any single day, a campaign can spend up to twice its daily budget.
Across the budget week, it will not spend more than seven times its daily budget.

The budget week runs from Sunday to Saturday in your ad account's time zone. If delivery is light early in the week, the unused amount can be spent later in the same week. If a campaign uses up its weekly allowance early, it can stop delivering until the next budget week, even while it still shows as active.

Example: with a daily budget of 1,000 THB, a campaign can spend up to 2,000 THB on a busy day but no more than 7,000 THB across the Sunday-to-Saturday week. If you change the budget mid-week, the seven-day limit is prorated from the time of the change through the following Sunday at midnight.

If you need a hard ceiling for the whole flight, choose a campaign total budget instead, and Ads Manager paces spend across your campaign dates. OpenAI suggests newcomers start with a daily budget so they can watch delivery before committing to a total. Treat the budget type as a one-way choice: you can change the amount later, but not the type.

When will you be charged for ChatGPT Ads?

ChatGPT Ads use postpay billing. Before any campaign can deliver, you create a billing profile with your business name, business address and invoice email, and you add a credit card. Your bank may show a temporary authorisation hold when you add the card. It is released after verification, although it can stay visible for eight days or longer.

Once ads run, spend accrues on your account. For self-serve card accounts, the card is charged each time unpaid spend reaches the payment threshold OpenAI assigns to your account, and any remaining balance is charged at the end of the month. New accounts usually start with a lower threshold that rises over time with successful payments. The threshold only decides when you are charged. It is not a budget and not a spending cap.

Two timing details save a lot of confusion. Spend figures in Ads Manager can lag by seven to eight hours, so a spend of zero on the dashboard does not mean nothing has accrued. And ads can keep appearing for up to 24 hours after you pause a campaign, and that delivery is billable.

Use a card that matches your business country. OpenAI's guidance is that the billing information and payment method should match the business entity and country used to create the account, so a Thai company should use a Thai card and billing address. You can add your tax ID for invoices under Billing, then Settings.

How should a Thai business plan its first ChatGPT Ads budget?

Start from what you want to buy, then let OpenAI's rules shape the numbers.

Give each campaign one goal. Awareness points to Views. Traffic to a specific service page points to Clicks. Leads or sales point to Conversions, once tracking is live.
Plan by the week. Because a daily budget is a seven-day average, decide a weekly figure and divide it by seven. Daily spend will move above and below that average.
Set bids with the Ads Manager guidance. Start within OpenAI's suggested range for click campaigns, then adjust when Ads Manager flags a bid as likely to limit delivery.
Give the test time. OpenAI advises giving campaigns enough time and budget to gather meaningful data before making large changes to bids, budgets or creative.
Keep media and management separate. The budget you set in Ads Manager is paid to OpenAI. An agency management fee is a separate line.

If you already size ad budgets from the value of a lead, the same logic works here, and our guide to setting an ads budget from lead value explains the method. Spend only pays off when the click lands on a page that persuades, so make sure the destination is built for paid traffic. Our landing page design team builds pages for exactly that job.

FAQ

Do ChatGPT Ads charge per conversion?

No. Views campaigns are billed per 1,000 impressions and Clicks campaigns per valid click. The Conversions objective optimises delivery toward a conversion event, but it is still billed per valid click (oCPC) or per 1,000 impressions (oCPM).

What is the minimum daily budget for ChatGPT Ads in Thailand?

OpenAI lists a minimum daily budget of 33 THB for ad accounts billed in Thai baht. If the campaign uses a fixed bid, the daily budget must also be at least the highest effective bid in that campaign.

Can a ChatGPT Ads campaign spend more than its daily budget?

Yes, on individual days. A campaign can spend up to twice its daily budget on one day, but no more than seven times its daily budget across the Sunday-to-Saturday budget week.

How much should I bid per click on ChatGPT Ads?

OpenAI recommends starting click campaigns with a maximum bid of 3 to 5 USD per click, then using the bid-strength guidance in Ads Manager to adjust. The auction decides the price you actually pay.

When is my card charged for ChatGPT Ads?

Billing is postpay. Your card is charged when unpaid spend reaches your account’s payment threshold, and any remaining balance is charged at the end of the month.
