OpenAI's release of GPT-OSS marks their first major open source LLM since GPT-2, featuring improvements in reasoning, tool usage, and problem-solving capabilities. The article explores its architecture, message formatting, reasoning modes, and tokenizer details.
This document details the features, best practices, and migration guidance for GPT-5, OpenAI's most intelligent model. It covers new API features like minimal reasoning effort, verbosity control, custom tools, and allowed tools, along with prompting guidance and migration strategies from older models and APIs.
OpenAI releases gpt-oss-120b and gpt-oss-20b, two state-of-the-art open-weight language models that deliver strong real-world performance at low cost. They outperform similarly sized open models on reasoning tasks and are optimized for efficient deployment.
AI researchers at Stanford and the University of Washington trained an AI 'reasoning' model named s1 for under $50 using cloud compute credits. The model, which performs similarly to OpenAI’s o1 and DeepSeek’s R1, is available on GitHub. It was developed using distillation from Google’s Gemini 2.0 Flash Thinking Experimental model and demonstrates strong performance on benchmarks.
