Short answer
ChatGPT has a free plan, but GPT-5.2 is not listed in OpenAI’s current Free-tier model lineup. OpenAI’s Free Tier FAQ currently names GPT-5.6 Luna for Free users and notes that the default model and limits can change. So “ChatGPT is free” does not mean you can choose GPT-5.2 for free. (help.openai.com)
The API is different: GPT-5.2 is available through the OpenAI API, but API use is billed separately. OpenAI lists GPT-5.2 at $1.75 per 1 million input tokens and $14 per 1 million output tokens; cached input tokens receive a 90% discount. (openai.com)
Information checked November 9, 2026. Model availability and limits may change.
ChatGPT Free versus GPT-5.2
OpenAI says the Free plan includes access to ChatGPT, while its current Free Tier FAQ identifies GPT-5.6 Luna as the Free model. That FAQ does not list GPT-5.2 as a Free-tier option. (help.openai.com)
GPT-5.2 launched in ChatGPT with a rollout starting with paid plans. That launch announcement is historical, however; it does not guarantee that GPT-5.2 is still selectable on any particular paid plan today. OpenAI says model availability can change and points users to the model picker for the options available to their account. Check the picker before paying specifically for GPT-5.2. (openai.com)
For budget context, ChatGPT Plus is $20 per month, billed monthly, but OpenAI does not promise on its Plus page that GPT-5.2 is currently included. Don’t subscribe to Plus solely to get GPT-5.2 unless your account’s model picker or current plan details confirm access. (help.openai.com)
GPT-5.2 API pricing for production
API access is not included with a ChatGPT subscription. OpenAI bills ChatGPT and the API separately, and GPT-5.2’s API pricing is based on token usage. (help.openai.com)
| GPT-5.2 API usage | Price (USD) |
|---|---|
| Input | $1.75 per 1 million tokens |
| Cached input | 90% less than the input rate* |
| Output | $14 per 1 million tokens |
*OpenAI states the cached-input discount as 90% off the input price. Actual charges depend on your token usage and any other billable tools or features. (openai.com)
Example estimate: If an application processes 1 million input tokens and generates 100,000 output tokens, the estimated model charge is $3.15: $1.75 for input plus $1.40 for output. This is an arithmetic example using the published rates, not a measured workload; tool calls or other billable features can add costs. (openai.com)
The GPT-5.2 model page lists the API’s Free rate-limit tier as not supported, so don’t budget on a free API tier for this model. Some paid ChatGPT Pro and eligible Business subscriptions may offer claimable API credits, but those credits have separate eligibility and API billing conditions; they are not the same as free ChatGPT access.

Which route makes sense?
- Just want to use ChatGPT at no cost? Use the Free plan, but expect the model shown in your account—not GPT-5.2 specifically. (
help.openai.com) - Want GPT-5.2 inside ChatGPT? Check the model picker and current plan details first. Plus costs $20 monthly, but that price alone does not confirm GPT-5.2 access. (
help.openai.com) - Need GPT-5.2 in a production application? Budget for API token charges separately from any ChatGPT subscription; estimate input and output usage with the rates above. (

A third-party service advertising “free GPT-5.2” may be offering access through its own product. That does not establish that GPT-5.2 is included in ChatGPT Free or that OpenAI API usage is free.
