GPT-5 mini
OpenAI's cost-efficient GPT-5-tier model — most of the quality at a fraction of the cost
Verdict
The default now for classification, extraction, summarisation, and simple chat — meaningfully sharper than GPT-4o mini for the same rough price. Inherits GPT-5's unified reasoning at lower latency. First choice for cost-sensitive apps that outgrew GPT-3.5-era models.
