OpenAI: GPT-5.4 Mini
OpenAI's GPT-5.4 Mini is an AI model capable of processing text, files, and images, with a context length of 400,000 tokens and the ability to handle reasoning tasks. It supports tools integration but does not offer structured output. While it excels in certain areas like coding, its agentic performance lags behind other models. For organizations that require robust text-based applications, especially those involving file or image analysis, GPT-5.4 Mini is a solid choice despite its higher cost at $0.75 per million input tokens and $4.5 per million output tokens. Its blended benchmark score of 70.8 across three independent assessments suggests it performs well in practical applications but may not be the top performer in every niche.
