# GPT-5.5
## Query Intents
- Understand pricing, provider availability, context window, and capabilities for GPT-5.5.
- Compare GPT-5.5 against other models available through PipeLLM.
- Find the canonical model identifier to use in SDK or API requests.
## Overview
GPT-5.5 is the latest frontier-grade model in the GPT-5 series, offering stronger agentic and long context perfomance compared to GPT-5.1. It uses adaptive reasoning to allocate computation dynamically, responding quickly to simple queries while spending more depth on complex tasks.

Built for broad task coverage, GPT-5.5 delivers consistent gains across math, coding, sciende, and tool calling workloads, with more coherent long-form answers and improved tool-use reliability.
