3 Key Differences of Google Gemini 1.5 Pro and OpenAI ChatGPT 4o

Please get an overview of the key differences between Google Gemini 1.5 Pro and OpenAI ChatGPT 4o below.

Performance:

  • Gemini 1.5 Pro is optimized for longer context windows.
  • GPT-4o outperforms Gemini 1.5 Pro in complicated tasks requiring deep reasoning and nuanced understanding.

Context window:

  • Gemini 1.5 Pro has a massive 1 million token context window, making it suited for flawlessly handling massive, complicated inputs.
  • GPT-4o is designed for efficiency but has a smaller 128,000 token context window. In other words, it's adequate for most common apps but less suitable for very long inputs.

Cost:

  • Gemini 1.5 Pro is less effective when the inputs are less than 128k tokens. Nevertheless, these two models have no difference if the input has more than 128k tokens.
