Which to pick

Pick **Gemini 2.5 Pro** for long-context work — its 1M-token window is roughly 8x GPT-4o's 128k, and the $1.25 in / $10 out per Mtok pricing makes large-input workloads dramatically cheaper. Use Pro for full-repo ingestion, long-document synthesis, and any task where the bottleneck is "fit it all in one prompt." Pick **GPT-4o** for multimodal team chat — vision over screenshots and charts, document layout extraction, audio in/out, integrated voice. On short text-only conversational turns the quality gap is small; reach for GPT-4o when the workload genuinely needs OpenAI's mixed-media handling, and Gemini Pro when context length or input cost is the constraint.
