Detailed Analysis
GPT-5.4 and Gemini 2.5 Pro take different approaches to frontier AI. GPT-5.4 focuses on versatility with full multimodal output, while Gemini 2.5 Pro emphasizes raw context capacity and reasoning depth.
Gemini 2.5 Pro's 1 million token context window is transformative for applications that need to process entire codebases, book-length documents, or hours of video in a single pass. GPT-5.4's 256K context, while significantly improved over GPT-4o, cannot match this.
On pricing, Gemini 2.5 Pro is significantly cheaper at $1.25/$5 per million tokens compared to GPT-5.4's $2.50/$15. Even with Gemini's thinking mode, the cost advantage is substantial.
However, GPT-5.4 responds to a broader ecosystem with wider developer tooling, more third-party integrations, and extensive community knowledge. Its audio and video output capabilities are unique among frontier models.
For reasoning and math, Gemini 2.5 Pro scores higher (92/91 vs 90/89), making it the better choice for analytical tasks.
