GPT-5.5 drops with agentic intelligence, computer use

GPT-5.5 marks the official transition of LLMs from "chatbots" to "agents," shifting the focus from generation to autonomous execution.

• –High scores in OSWorld-Verified (78.7%) and SWE-Bench Pro (58.6%) indicate the model is now capable of handling professional-grade engineering and OS-level tasks.
• –The 1M token context window combined with agentic planning allows for deeper codebase understanding and long-running multi-file refactors.
• –Workspace Agents introduce a persistent layer to AI collaboration, moving beyond transient chat threads to long-lived digital employees.
• –The "Pro" pricing tier ($30/$180 per 1M tokens) reflects a move toward value-based pricing for high-stakes enterprise and scientific workflows.
• –Increased efficiency means GPT-5.5 can handle more complex reasoning paths without the per-token latency penalty of previous frontier models.
