OpenAI: GPT-5
Analysis Summary
OpenAI's GPT-5 is a flagship model with an intelligence index of 44.6, GPQA of 0.854, HLE of 0.265, and an agentic index of 58.7. It supports vision, tool use, function calling, and file input across a 400K context window. Instruction following (ifbench 0.731) and long-context reasoning (lcr 0.756) are among the strongest in this batch, and the tau2 score of 0.848 reflects high agentic reliability.
For businesses, GPT-5 is well suited to autonomous agents, long-document analysis, complex content generation, and multimodal workflows. The 400K context window is a meaningful advantage for teams working with large codebases, lengthy contracts, or extended research documents. Vision and function calling add further breadth.
At $1.25 input and $10 output, it is expensive for high-volume use but competitive for a model at this capability level. Teams needing frontier reasoning with broad capability coverage will find GPT-5 a strong fit; those with budget constraints should consider GPT-5 Mini.
