Issues by Category
Bug upgrades users from Plus to Pro without consent
Trustpilot reports a bug that keeps upgrading customers from Plus ($20) to Pro ($200) without consent. OpenAI won't acknowledge it or admit fault. Users find it nearly impossible to cancel subscriptions.
ChatGPT Pro 200 limits cut in half for the same price
After DevDay (Sep 29, 2026) Pro became three tiers: $100, $200 and $500. Pro 200 kept its $200 price but its usage dropped from 20x to 10x Plus and Pro-model chat messages from 200 to 100 per week from Oct 30, 2026; the old allowance now needs the $500 tier.
Free tier severely limited to 10 messages per 5 hours
The Free plan allows roughly 10 messages on the flagship model every 5 hours before silently falling back to a mini model. Uploads, image generation and deep research are also tightly capped, pushing regular users to Go ($8) or Plus ($20).
Ads in ChatGPT on Free and Go plans
Since January 2026 OpenAI shows ads to logged-in US users on Free and the $8 Go plan. Free users can opt out only by accepting fewer daily messages, and earlier app 'suggestions' shown even to $200 Pro users triggered backlash before being turned off.
GPT-5 quality feels like a downgrade
Nearly 5,000 users complained on Reddit that GPT-5 'feels like a downgrade.' TechRadar reports users find it 'creatively and emotionally flat' and 'genuinely unpleasant to talk to.' OpenAI reversed course and brought back GPT-4o as an option after backlash.
Coding ability feels downgraded since GPT-5
Developer forum threads report GPT-5 coding feels downgraded - scripts that used to work now fail, solutions are weaker and less consistent. Users describe it taking more time to complete coding tasks than before.
Slow and laggy responses especially on GPT-4/5
Many users complain responses are slow or laggy especially on advanced models. GPT-5.2 Pro mode extended reasoning takes 30-60 seconds, breaking conversational flow. Tasks genuinely take more time than before according to users.
Frequent outages - 44 incidents in 90 days
ChatGPT had 44 incidents in 90 days including 1 major outage with median duration of 1 hour 42 minutes. Major global outage in June 2025 lasted 15+ hours. February 2026 saw 28,000+ outage reports in one day. 99.3% uptime means ~5 hours downtime per month. Image generation broke in several 2026 incidents (July 7, July 21/27, September 8), and 'Error in message stream' spikes were acknowledged in OpenAI release notes in February 2026.
Hallucinations still common requiring verification
G2 reviews note ChatGPT can occasionally generate inaccurate information requiring verification for critical tasks. While hallucinations have improved, they remain a concern. Users cannot blindly trust outputs for important work.
Random refusals and lost chat histories
Users report random refusals, lost chat histories, servers crashing mid-conversation, and answers that feel overly cautious or oddly incomplete. Reliability concerns are driving users to explore alternatives.
Overfiltered safety responses frustrate users
GPT-5.2 is criticized as 'overregulated, overfiltered, and frustrating.' Topics GPT-4 discussed thoughtfully now trigger refusals or heavily hedged responses. Users say it 'sounds like someone who just finished corporate compliance training and is scared to improvise.'
Misunderstands instructions leading to unusable results
Trustpilot reviews report the tool often misunderstands instructions, leading to incorrect or unusable results. The system's tendency to ignore specific requests and provide inconsistent outputs frustrates paying customers.
Memory and context issues within conversations
Users complain the model constantly repeats answers to previously asked questions, wasting time and tokens. Some report it can't hold onto basic facts already established within the same thread. Context handling frustrates users.
Customer support is automated loops with no resolution
Trustpilot reviews report support is 'non-existent unless it's simple' - all automated, going round in loops. Formal complaints mishandled by human agents then redirected to AI bots with generic replies. No human ever reviews cases, no refunds provided.
Conversations used for training by default
By default on Free, Plus, and Pro plans, conversations are used to train OpenAI's models. Q4 2025 research shows 35% of employee ChatGPT inputs contain sensitive data. Data retained indefinitely for legal discovery (NYT lawsuit). Must manually opt out in Settings.
Regret Patterns
Common reasons users regret choosing ChatGPT.
Upgraded to Plus/Pro then experienced quality regression
Users subscribed expecting premium quality but GPT-5 feels like a downgrade from GPT-4. Creative writing is 'flat,' coding is weaker. Paid users feel they're getting less than before OpenAI launched new models.
Relied on ChatGPT then hit major outage during critical work
Users depending on ChatGPT for work experienced 15+ hour outages or crashes at critical moments. 44 incidents in 90 days means outages are not rare. Lost work and missed deadlines due to reliance on single tool.
Shared sensitive data before understanding training policy
Users input confidential business information before realizing data trains OpenAI models by default. 35% of employee inputs contain sensitive data. Too late to remove once shared. Should have opted out first.
Got stuck in subscription cancellation nightmare
Users attempting to cancel report automated loops with no human resolution. Some were upgraded from Plus to Pro without consent. Billing continues despite cancellation attempts. Had to dispute through bank.
Expected Plus to remove all limits but hit message caps
Plus subscribers discovered GPT-5.2 Thinking is capped at 3000 messages/week. Expected 'premium' experience but still face limitations. Pro at $200/month required for truly unlimited access.
Built workflow around ChatGPT then safety filters blocked use case
Users built content workflows then found GPT-5.2's expanded safety filters block topics that worked before. Topics GPT-4 handled now trigger refusals. Had to switch tools mid-project.
When ChatGPT Breaks Down
Specific scenarios where ChatGPT fails or underperforms.
Critical work during major outage
ChatGPT experiences 44+ incidents per 90 days including major outages lasting 15+ hours. Users relying on ChatGPT for deadline-critical work can be left stranded. 99.3% uptime means ~5 hours monthly downtime.
Use case blocked by expanded safety filters
GPT-5.2's safety filters are dramatically expanded compared to GPT-4. Topics that worked before now trigger refusals. Users building on specific capabilities find their workflows broken by updates.
Billing system charges after cancellation
Trustpilot reports subscription cancellation issues - charges continuing after cancellation, forced upgrades from Plus to Pro. Support is automated loops without resolution. Bank disputes may be necessary.
Sensitive data shared before opt-out
Data trains models by default on Free/Plus/Pro. Once shared, sensitive information cannot be removed. 35% of employee inputs contain sensitive data. Enterprise tier required for data protection.
Coding quality drops after model update
GPT-5 is reported to feel 'downgraded' for coding. Scripts that worked before fail, solutions are less consistent. Developers relying on ChatGPT for code assistance experience productivity drops.
Free tier limits make evaluation impossible
Free tier's 10 messages/5 hours cap makes proper evaluation nearly impossible. Users can't assess if ChatGPT fits their needs without paying. Go ($8) or Plus ($20) required for meaningful use.
