ChatGPT's pricing: every plan and the API
ChatGPT has 4 plans in the US: ChatGPT's free plan, ChatGPT Go at $8, ChatGPT Plus at $20 and ChatGPT Pro at $100 or $200 or $500 a month. None publishes a chat count: OpenAI says Pro's tiers differ in usage, without numbers, and Pro 200 takes new subscribers again. Through OpenAI's API, a typical GPT-6 Astra message costs $0.0750.

Per million tokens in and out, from llmwise's catalog (OpenAI's list price), and a typical message: 4,000 tokens in, 700 out. Beside each, its count on llmwise Pro ($20).
| Model | API price per million tokens (in / out) | A typical message | On llmwise Pro | Least a message costs on llmwise Pro |
|---|---|---|---|---|
| GPT-6 Astra | $10.00 / $50.00 | $0.0750 | Up to 31 a month | $0.65 |
| GPT-6.1 Sol | $2.00 / $10.00 | $0.0150 | Up to 125 a month | $0.16 |

llmwise's paid plans also cap AI cost each month for fair use (Plus $3.75, Pro $7.50, Max $20, Ultra $42, Studio $85). A whole month of typical messages costs less than that; very long messages and deep research cost more. Every limit, explained.
What does OpenAI do with your ChatGPT chats?
From OpenAI's privacy pages as they read on September 28, 2026. For comparison, llmwise trains no models on what you send, and a chat stays until you delete it.
| Service | Used for training | Opting out | How long chats stay |
|---|---|---|---|
| ChatGPT | By default, yes | Turn off “Improve the model for everyone”, or use Temporary Chat | Temporary Chats up to 30 days; the page gives no period for saved chats |
“Data controls let you choose whether your conversations help train OpenAI models.”
Quoted from OpenAI Help Center: Data controls in ChatGPT
“When Improve the model for everyone is off, your new conversations won’t be used to train OpenAI models.”

“may be retained for up to 30 days for safety purposes”
