Analysis
The short version Gemini runs on Gemini 2.5 Pro, which has a 1M-token context window. ChatGPT runs on GPT-5, which has a 400K-token context window through the API. Both are top-tier assistants. Which one fits better depends on the tools you already use.
Long context Gemini can take in far more at once: whole books, long videos and large codebases. That makes it a strong choice for research over big documents.
Ecosystem Gemini is built into Gmail, Docs, Drive, Android and Chrome. ChatGPT has custom GPTs, a large connector ecosystem, and desktop apps that work with your other software.
Quality On reasoning and coding benchmarks the two trade the lead with each new release. GPT-5 is generally rated stronger on agentic, multi-step tasks. Gemini 2.5 Pro is especially strong on multimodal understanding.
Price Both have free tiers. Their paid plans cost about the same and include extras: Google bundles cloud storage, and OpenAI gives higher usage limits.
