Chatgpt Review 2025 - Features, Pricing & Alternatives

### Hallucinations Remain a Real Problem ChatGPT confidently generates incorrect information. It invents citations, fabricates statistics, and presents plausible-sounding falsehoods with the same confidence as verified facts. The frequency has decreased with GPT-4o compared to earlier models, but it has not been eliminated. I have caught fabricated API documentation, invented research papers, and incorrect code library methods. Every output that matters must be verified. This verification overhead partially erodes the time savings the tool provides. Users who trust ChatGPT output without checking are making a serious mistake. ### Usage Limits Create Workflow Interruptions Even on the Plus plan, heavy usage hits rate limits. During intensive work sessions, particularly with GPT-4o, I occasionally get throttled and forced to wait or switch to GPT-4o mini. These interruptions break flow state and are the most frustrating aspect of daily use. The limits are not clearly published, which makes planning difficult. Some days I can run 80 messages without issue. Other days I hit a wall at 40. The unpredictability is worse than a known hard limit would be. ### No Offline Capability ChatGPT requires an internet connection for everything. No offline mode exists for mobile or desktop. If your connection drops during a long generation, you lose that output. For users who work in areas with unreliable connectivity or during travel, this is a significant limitation.
