OpenAI officially released two versions of the GPT-5.1 series, and ChatGPT's emotional intelligence has greatly improved.

OpenAI's upgraded AI version, GPT-5.1, focuses on optimizing the dialogue experience rather than simply improving performance metrics. The new version includes two main models: Instant and Thinking. The former emphasizes more human-like communication (such as adaptive thinking and eight style presets), while the latter enhances professional reasoning capabilities (simplifying terminology). Compared to its predecessor, GPT-5.1 shows significant improvements in emotional interaction and command understanding.
