OpenAI: GPT-5 Mini
Analysis Summary
OpenAI's GPT-5 Mini achieves an intelligence index of 41.2, GPQA of 0.828, and an agentic index of 50.9, with vision, tool use, function calling, and file input across a 400K context window. Instruction following (ifbench 0.754) is the strongest in this batch, and long-context reasoning (lcr 0.680) is excellent. The livecodebench score of 0.838 is also strong.
For businesses, GPT-5 Mini is a highly capable all-rounder suited to content generation, agentic workflows, long-document analysis, and multimodal tasks. The combination of a 400K context window, vision, and strong instruction following makes it particularly valuable for client-facing content and complex automation pipelines.
At $0.25 input and $2 output, it offers strong value relative to its capability tier. For most business workloads that do not require the absolute frontier of reasoning, GPT-5 Mini is the more cost-effective choice over GPT-5, and it should be the default recommendation for teams adopting the GPT-5 family.
