Summary

OpenAI has released GPT 5.4, its latest large language model, featuring a 1 million token context window. This version significantly enhances multimodality and vision capabilities, allowing it to interpret screen screenshots and take corresponding actions. A key innovation in GPT 5.4 is its "steerability" feature, which enables users to interrupt the model's internal chain of thought and redirect its reasoning process without restarting from scratch. This capability addresses the challenge of guiding complex AI models more effectively. Additionally, GPT 5.4 is designed to operate with greater token efficiency.

Key takeaway

For AI product managers and developers integrating advanced models, GPT 5.4's steerability and multimodal vision capabilities offer new avenues for interactive AI. You should explore its 1 million token context window for complex tasks requiring deep situational awareness, and leverage the ability to interrupt and redirect its thought process to achieve more precise and controlled outcomes, reducing the need for complete restarts.
