As of November 3, 2026, OpenAI’s published shared-project limits for ChatGPT are plan-based: Free projects top out at 5 collaborators and 5 files, Plus and Go projects at 10 collaborators and 25 files, and Pro projects at 100 collaborators and 40 files, according to OpenAI’s own listing of shared-project limits. OpenAI says shared projects support two collaboration modes, “Only those invited” and “Anyone with a link,” and that both modes sit under the same plan-based ceilings on collaborators and files. OpenAI also says usage limits may apply based on account activity and subscription level. The article states that the headline claiming these limits could frustrate users is a judgment, not a measurement, and that OpenAI’s material does not describe an outage, a price change, or a rule change tied to shared projects, nor does it quote any user complaints.
