OpenAI o3 and o4-mini System Card
OpenAI's o3 and o4-mini now ship with full tool stack—web, Python, image gen, and memory all native.
Why it matters
OpenAI is collapsing the gap between reasoning models and agentic capabilities, bundling web browsing, code execution, and memory into base models. This signals a shift toward reasoning-as-infrastructure rather than bolt-on features, directly competing with Claude's native tool integration.
The key facts
4 to knowo3 and o4-mini feature integrated tool capabilities: web browsing, Python execution, image/file analysis, image generation, canvas, automations, file search, memory
System Card published April 16, 2025 — official capability/safety documentation
Tool integration native to models rather than via API wrappers
Memory feature suggests persistent context across sessions
