o3 and o4-mini Release: Reasoning Models Begin Actively Using Full Tool Suite
OpenAI released o3 and o4-mini, enabling reasoning models to combine browsing, code, file, and image tools in ChatGPT.
Reasoning and action converge; models shift from thinking in a single context to selecting tools, verifying results, and completing tasks.
Native tool selection integrates planning, execution, and verification into a unified reasoning process.
Agent capabilities are gradually being built into flagship models, compressing the value of pure orchestration layer products.
Application companies' competitiveness must be built on proprietary data, permission systems, evaluation, and complete business processes.
Observe tool selection accuracy, error recovery, long-task cost, and safety controls.
