OpenAI in 2025: Your Ultimate Guide to GPT-5, Agents, and the AI ...
Excerpt
Pros š Cons š State-of-the-art performance in reasoning and complex tasks. High cost for flagship models, especially at high volume (Spaceo Technologies). Powerful and flexible developer platform (API, Agents SDK). ā¦ Its ability to "think" before responding yields more accurate and nuanced results. However, for simpler, everyday queries, some users have reported that GPT-5 can feel slower than the highly optimized GPT-4o. There was even some initial community backlash about performance degradation for simple coding tasks before OpenAI fine-tuned the model routing (hdsquares.com).
