Do OpenAI and Anthropic train on your chats?

As each company's privacy pages put it on September 28, 2026. Neither question arises on llmwise: it doesn't train on your content, and you decide when a chat is deleted.

ChatGPT Plus and Claude Pro: training and retention
App	Training on your chats	How to opt out	Retention
ChatGPT	Yes, unless you opt out	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
Claude	Only if you allow it	Leave Model Improvement off in Privacy Settings, or use Incognito chats	Deleted chats go within 30 days; up to 5 years, de-identified, if you allow training

“Data controls let you choose whether your conversations help train OpenAI models.”
Quoted from OpenAI Help Center: Data controls in ChatGPT
“You choose to allow us to use your chats and coding sessions to improve Claude”
Quoted from Anthropic Privacy Center: Is my data used for model training?

Both in one: llmwise Pro

llmwise Pro ($20) beside both plans. Its monthly counts assume the allowance goes to one model.

ChatGPT Plus, Claude Pro and llmwise Pro: each model's count
Model	ChatGPT Plus	Claude Pro	llmwise Pro
GPT-6 Astra	In Work and Codex only: an estimated 5–45 every 5 hours	Not offered: Claude only	Up to 31 a month
GPT-6.1 Sol	Not named on its pages	Not offered: Claude only	Up to 125 a month
GPT-6 Sol	In Work and Codex; not in Chat yet	Not offered: Claude only	Up to 125 a month
Claude Fable 5.1	Not offered: GPT only	Paid for separately, from the first message	Up to 31 a month
Claude Opus 5.5	Not offered: GPT only	Included; Anthropic's table names the family, not the version	Up to 62 a month
Claude Sonnet 5.5	Not offered: GPT only	Not named on its pages	Up to 125 a month

Behind Pro's counts is a $7.50 monthly ceiling on AI cost, its fair-use limit: typical use stays under it, and huge messages or deep research get there first. Every limit, explained.
