Gemini 1.5 Pro vs GPT4o (Omni): Performance, Benchmark and Capabilities Comparison

With the announcement of the GPT-4o model, the realm of AI got stronger. Also, the mega rival Google debuted the Gemini 1.5 Pro model for consumers via Gemini Advanced after the Google I/O event. Now that the two flagship models are the talk of town, let’s compare their capabilities, strengths, and weaknesses. 

In this article, you will get a detailed analysis of their features, performance, benchmarks, and capabilities to make informed decisions based on their specific needs in the AI landscape.

About Gemini 1.5 Pro & GPT 4o (Omni)

Gemini 1.5 Pro: Gemini 1.5 Pro is the first Gemini 1.5 model. It’s a mid-size multimodal model, optimized for scaling across a wide range of tasks, and performs at a similar level to 1.0 Ultra. It also introduces a breakthrough experimental feature in long-context understanding.

Gemini 1.5 Pro comes with a standard 128,000 token context window. It can process vast amounts of information in one go — including 1 hour of video, 11 hours of audio, and codebases with over 30,000 lines of code or over 700,000 words. 

GPT 4o: GPT-4 Omni is a recent addition to the world of AI advancement by Google. It is a step towards much more natural human-computer interaction. The AI model accepts as input any combination of text, audio, image, and video and generates any combination of text, audio, and image outputs. 

GPT 4o can respond to audio inputs in as little as 232 milliseconds, with an average of 320 milliseconds, which is similar to human response time in a conversation. Also, it matches GPT-4 Turbo performance on text in English and code, with significant improvement on text in non-English languages, while also being much faster and 50% cheaper in the API. 

Gemini 1.5 Pro vs GPT4o (Omni): Key Differences

The table below compares two large language models (LLMs): Gemini 1.5 Pro and GPT-4o. While both are under development, Gemini focuses on conversation, while GPT-4o excels at generating different creative text formats.

Gemini 1.5 Pro & GPT 4o: Performance, Benchmark and Capabilities Comparison

GPT-4o set a new benchmark for AI efficiency in the benchmark tests, achieving an average speed boost of 30% over its predecessor. In tests requiring quick reactions and intricate calculations, GPT-4o has continuously beaten Gemini. 

GPT-4o sets a new high score of 88.7% on 0-shot COT MMLU (general knowledge questions). All these evals were gathered with our new simple evals library. In addition, on the traditional 5-shot no-CoT MMLU, GPT-4o sets a new high score of 87.2%. 

GPT-4o sets a new state-of-the-art on speech translation and outperforms Whisper-v3 on the MLS benchmark.

Vision Understanding Evals

GPT-4o achieves state-of-the-art performance on visual perception benchmarks. All vision evals are 0-shot, with MMMU, MathVista, and ChartQA as 0-shot CoT.

What to choose between Gemini 1.5 Pro and GPT4o (Omni)?

The choice between the two titans depends on your needs. If you crave a conversational partner, Gemini is the way to go. If creative text generation is your priority, GPT-4o holds promise, but access remains limited.

Gemini is designed for dialogue, it excels at understanding context and responding naturally in conversations. Whereas, OpenAI claims GPT-4o is a master of generating various creative text formats, potentially including code, scripts, musical pieces, etc.

However, Gemini comes with limited public availability, and information on parameter size makes it hard to gauge raw power for tasks beyond dialogue. And GPT 4o is currently available only for researchers, and its focus on text generation might limit its conversational abilities compared to Gemini.

In conclusion, It’s evidently clear that Gemini 1.5 Pro is far behind ChatGPT 4o. Even after improving the 1.5 Pro model for months while in preview, it can’t compete with the latest GPT-4o model by OpenAI. From commonsense reasoning to multimodal and coding tests, ChatGPT 4o performs intelligently and follows instructions attentively. Not to miss, OpenAI has made ChatGPT 4o free for everyone.

The only thing going for Gemini 1.5 Pro is the massive context window with support for up to 1 million tokens. In addition, you can upload videos too which is an advantage. However, since the model is not very smart, I am not sure many would like to use it just for the larger context window.
