Hi @median creek. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Here’s what the knowledge sources say specifically for the Free tier:
1. File & image uploads (ChatGPT Free)
- Free users can:
- Upload images or files in prompts. [Free tier FAQ]
- Use file uploads, data analysis, and image creation, but with stricter rate limits than paid tiers. [Free tier FAQ]
- More detailed upload limits (applies across plans, with specific Free limits called out):
- 3 file uploads per day for Free users. [File uploads FAQ]
- Per-file limits:
- Max 512 MB per file
- Max 2M tokens for text/doc files (not spreadsheets)
- Images up to 20 MB each
- Global caps: 10 GB per end-user, 100 GB per org. [File uploads FAQ]
2. Image generation (ChatGPT Free)
- Free users can create images in ChatGPT. [Free tier FAQ]
- There is a separate rate limit for “Create images in ChatGPT” that is independent of the GPT‑4o text limit; if you hit it, you must wait for it to reset. [Free tier FAQ]
- A separate note mentions that ChatGPT Free users can create up to two images per day with DALL·E 3 (this is described as a rollout). [DALL·E 3 for Free]
- GPTs can also generate images via DALL·E, and this is available to Free users, but still subject to the stricter Free-tier limits. [GPTs FAQ Free]
Because limits can change over time and may be adjusted dynamically, the articles recommend treating these as current guidance rather than permanent guarantees.
3. “Pro model” usage on Free tier
The knowledge sources do not describe a “Pro model” for Free users. They do say:
- Free users are defaulted to GPT‑4o with a limited number of messages in a 5‑hour window; after that, they are switched to GPT‑4.1 mini. [Model selector / GPT‑4o access; Free tier FAQ]
- Exact numeric message caps for GPT‑4o on Free are not specified in these sources; they only say “limited number of times within a five hour window” and that you’ll be notified when you hit the limit. [Free tier FAQ]
There is information about GPT‑5.1 usage limits, but that applies to ChatGPT Free, Plus, Business, Pro in general and doesn’t break out additional daily limits beyond the 5‑hour message caps for GPT‑5.1 itself. [GPT‑5.1 in ChatGPT]
Summary for Free tier (from these docs):
- Uploads: 3 file uploads per day; 512 MB per file; 20 MB per image; other size/token caps as above. [File uploads FAQ]
- Image generation: Can create images in ChatGPT; separate tool limit; one article specifies up to 2 DALL·E 3 images per day for Free users. [Free tier FAQ; DALL·E 3 for Free]
- Model usage: Limited GPT‑4o (or GPT‑5.1, depending on rollout) messages in a 5‑hour window; exact numeric cap for Free is not given in these sources. [Free tier FAQ; GPT‑5.1 in ChatGPT]
