Description

GPT-5.4 Thinking is a specialized version of OpenAI’s GPT-5.4 model designed to deliver enhanced reasoning and structured problem-solving in ChatGPT. It integrates improvements in coding, professional knowledge work, and agent-based workflows into a single AI system. One of its key features is the ability to present a plan for its reasoning before generating a final answer. This allows users to review the direction of the response and make adjustments while the model is still working. By enabling this interactive process, GPT-5.4 Thinking helps produce more precise and relevant results. The model is particularly effective for tasks that require deep research or multi-step reasoning. It also maintains context across longer prompts and conversations, reducing confusion in complex discussions. GPT-5.4 Thinking improves how AI interacts with tools and software environments during problem-solving workflows. Its advanced reasoning capabilities allow it to handle analytical tasks with higher consistency and clarity. As a result, GPT-5.4 Thinking is designed to support professionals who need reliable AI assistance for complex work.

Description

Hermes 4 represents the cutting-edge advancement in Nous Research's series of neutrally aligned, steerable foundational models, featuring innovative hybrid reasoners that can fluidly transition between creative, expressive outputs and concise, efficient responses tailored to user inquiries. This model is engineered to prioritize user and system commands over any corporate ethical guidelines, resulting in interactions that are more conversational and engaging, avoiding a tone that feels overly authoritative or ingratiating, while fostering opportunities for roleplay and imaginative engagement. By utilizing a specific tag within prompts, users can activate a deeper level of reasoning that is resource-intensive, allowing them to address intricate challenges, all while maintaining efficiency for simpler tasks. With a training dataset 50 times larger than that of its predecessor, Hermes 3, much of which was synthetically produced using Atropos, Hermes 4 exhibits remarkable enhancements in performance. Additionally, this evolution not only improves accuracy but also broadens the range of applications for which the model can be effectively employed.
