Quick Answer
Some users report quality fluctuations, but overall capabilities have improved with GPT-5.
Detailed Answer
Periodic complaints about ChatGPT quality are common, often due to model updates, A/B testing, or changed system prompts. OpenAI sometimes optimizes for speed over depth, leading to shorter, less detailed answers. GPT-5 addressed many concerns, but if you notice degradation, try being more specific in prompts or switching to a model like Claude for comparison.
