ChatGPT-5: OpenAI’s ChatGPT-5 is powered by the GPT-5 model, which was released on August 7, 2025 as the successor to GPT-4. GPT-5 is a multimodal large language model natively trained on both text and images, enabling it to understand and generate text with visual context seamlessly. At launch, it achieved state-of-the-art performance on a broad range of benchmarks in coding, mathematics, finance, and vision tasks. OpenAI reported major improvements in GPT-5’s abilities: faster responses, more accurate and detailed answers, stronger coding and writing skills, and significantly lower rates of hallucination compared to GPT-4. Notably, GPT-5 was designed to handle potentially harmful or sensitive prompts with “safe completions” – providing high-level, safe answers where possible instead of simply refusing queries. This reflects an updated alignment approach, aiming to be helpful yet avoid misuse. Another update is that ChatGPT-5’s style is less superficially agreeable – it’s more willing to provide critical or dissenting answers when appropriate rather than always saying “yes,” an adjustment to reduce sycophantic behavior.
