What’s the limits now, for all the plus users? I’ve started to create a table. Let’s add all the limits that apply for 2025 until now. Thanks.

Let’s correct. Where did I note down wrong?

Feature/Model Usage Limit Time Frame Notes
GPT-4o mini Unlimited N/A
GPT-4o 80 messages 3 hours
GPT-4 40 messages 3 hours Includes custom GPTs
o1 50 messages 1 week
o3-mini 150 messages 1 day Replaced o1-mini
o3-mini-high 50 messages 1 day For paid users
o1-pro N/A N/A Slower but thorough
Image generation Daily maximum 24 hours
Deep Research 10 queries 1 month For Plus users
DALL-E 3 40 messages 3 hours 200 images per day limit
Custom GPTs No specific limit N/A Uses GPT-4 message quota
Projects 20 projects N/A Per user
Chats per Project No fixed limit N/A 30+ reported without issues
Files per Project 20 files N/A 512MB per file, 2M tokens total
Custom Instructions Unlimited N/A 8,000 character limit each

Additional Notes:

  • Deep Research: Can analyze text, images, and PDFs; generates reports with citations.
  • DALL-E 3: Limits may reduce to 20 prompts per 3 hours during peak usage.
  • Custom GPTs: File upload limit of 20 files, each up to 512MB. For more about Custom GPT limits see here.
  • Projects: Supports Canvas for coding, voice mode, web search, and other integrations.
  • Usage limits and features may change; always check official documentation for updates.

Please let’s correct together where it’s wrong so we can solve it together until it’s correct - at least for now :slight_smile:

Mine doesn´t say O1 Preview…

it’s o1, o3 Mini and o3 Mini High

I just got a message saying I have 25 o1 messages yet until tomorrow 16:00. So I am not sure it’s weekly or daily. If it’s weekly, is it a coincidence it will reset TOMORROW?

That’s definitely true. We got no o1-preview anymore. Thanks for the help @rogerpenna :slight_smile: So, changed it right now.

I’m struggling to find updated info for ChatGPT Plus

This image lists the Chat GPT Plus usage limits for various models and features as of March 9, 2025. (Captioned by AI)

. The OpenAI information seems out of date and Perplexity is definitely giving me outdated information :woman_shrugging:t2:

I’m using o1 a lot today, no warning messages. But I have more important things to do later with a foggy brain and I’m going to need a thinking model available… Why would o1 be much more restricted than o3?

Deep research limit seems real, I got through that very quickly. I can’t use o3 models inside Projects but that doesn’t seem to be a rate limiting type of issue?

The information I got was:

GPT-4: 40 messages every 3 hours (includes custom GPTs).
• GPT-4o: 80 messages every 3 hours.
• GPT-4.5: 50 messages per week.
• GPT-4o mini: Unlimited usage.
• o3-mini: 150 messages per day.
• o3-mini-high: 50 messages per day.
• o1-preview: 50 messages per week.
• DALL-E 3 (image generation): 40 prompts every 3 hours, up to 200 images daily.
• Deep Research Tool: 10 queries per month.
• Projects: Up to 20 projects with 20 files each (512MB/file, 2M tokens total). Saw this on Threads

I didn’t put the limits for free tier in here for now.
That’s why the headline already states:

ChatGPT PLUS USER LIMITS…

I‘ve noticed that using 4o is also using up GPT-4 limits. When I reach a certain amount of 4o messages (about half) 4 gets a cooldown but 4o does not. Also it’s probably irrelevant now since 4 is going to end this month.
