OpenAI: GPT-5
Analysis Summary
GPT-5 is OpenAI's August 2025 flagship, sitting in the mid-tier of the current intelligence landscape with an index of 31.2. It pairs that reasoning capability with a strong agentic score of 55.4, full tool use and function calling, vision support, and a 400K context window, making it a well-rounded model for business workflows that span multiple modalities.
For teams running autonomous agents, document analysis, or customer-facing pipelines, GPT-5 covers a broad capability surface. Its livecodebench score is strong and its tau2 agentic reliability is high, so it handles multi-step tasks with reasonable consistency. The main limitation is that its intelligence index sits well below the current top tier, meaning it will underperform on the hardest reasoning tasks compared to models like Claude Opus 4.8 or GPT-5.5.
At $1.25 input and $10 output per million tokens, it is priced as a premium model. Teams that need broad capability breadth, vision, and reliable tool use in a single OpenAI-hosted model will find it a practical choice, but high-volume or budget-sensitive workloads should consider GPT-5 Mini instead.
