GPT-5.5 (high)
Analysis Summary
GPT-5.5 (high) is a compute-tier variant of OpenAI's GPT-5.5 flagship, benchmarking just below the standard release on intelligence and coding but remaining firmly in the top tier of the full model landscape. It carries the same strong agentic index and comparable instruction-following and long-context performance.
In practice, the capability gap between this variant and the standard GPT-5.5 is small enough that most business workloads will see equivalent results. It suits the same use cases: autonomous coding agents, complex reasoning tasks, long-document analysis, and multi-step tool-use pipelines. The lack of separately listed vision or function-calling flags in the data is worth verifying before deploying in multimodal workflows.
Pricing is identical to the standard GPT-5.5 at $5 input and $30 output per million tokens. Teams already using GPT-5.5 should default to the standard release for the marginal benchmark advantage, but this variant remains a capable alternative for workloads where the difference is immaterial.
