"Hello,
Thank you for reaching out to OpenAI Support and we appreciate you taking the time to describe what you’re experiencing in detail.
We completely understand how confusing it must be to see what appears to be automatic rerouting or model switching while using GPT-4o — especially as a Plus subscriber who expects consistent access to that model. We’d like to clarify what’s happening and make sure you’re getting the best experience possible.
What you’re describing — where responses seem different or “reroute” to a safety or fallback model — can occur when:
Temporary safety filters or content routing systems intervene to ensure compliance with our use policies, or
The selected model (GPT-4o) is briefly unavailable, leading the system to substitute a fallback configuration until the main model is restored.
In these cases, the model’s header may still display “GPT-4o,” but performance or tone can vary because a safety variant or low-latency replica is being used momentarily. These adjustments are automatic and do not reflect any permanent change to your account’s access level.
As of the most recent release, Plus subscribers continue to have full access to GPT-4o — the same flagship model used in ChatGPT Pro and Business plans. Legacy models (like GPT-4-Turbo and earlier versions) have been deprecated for Plus users, while newer model families, including GPT-5, are currently reserved for Pro, Business, and Enterprise tiers.
We’ve noted your feedback about the model routing experience and shared it internally with our product team — we know consistency matters, and your input helps us refine how model transitions are handled in the background.
With the rollout of GPT-5, OpenAI updated model availability across plans. According to our ChatGPT Release Notes:
Plus users have continuous access to GPT-4o, optimized for multimodal input and general use.
Pro, Business, and Enterprise users gain access to additional legacy and experimental models.
When brief load balancing or safety routing occurs, the system may temporarily shift to a safety variant of GPT-4o to maintain reliability and policy compliance.
Thank you for bringing this to our attention and for being such a valued Plus subscriber. We’ve confirmed that your account remains correctly provisioned for GPT-4o.
Best,
Christopher B

OpenAI could really just stop their "support", it's always the same meaningless garbage anyway. Nobody needs that in this way!
