What is GPT-4?
GPT-4, launched on March 14, 2023, is the beginning of the fourth generation of OpenAI's language model.
It marked many improvements over GPT-3.5 enabling it to handle more complex conversations. One of the biggest improvements from GPT-3.5 were advancements in reasoning, creativity, and problem-solving. GPT-4 fathered the ability to complete new tasks like generating quality content to accurately answering analytical and coding questions.
GPT-4 is available through the ChatGPT user interface and via OpenAI’s API for developers.
What is GPT-4o?
GPT-4o (“o” for “omni”), launched on May 13, 2024, is an updated version of OpenAI’s GPT-4 model. It is designed with enhancements to both efficiency and accessibility.
With a 128,000-token context window for longer conversations, GPT-4o’s biggest improvement is the ability to process multiple data types—including text, audio, images, and video—within the model. It also boasts faster response times, cheaper cost per token, and lower latency, making it a prime candidate for real-time applications, multilingual tasks, and high volume jobs.
GPT-4o is also available through the ChatGPT user interface and via OpenAI’s API for developers.
Comparing GPT-4o vs GPT-4
To understand the differences in these models, let’s look at GPT-4 and GPT-4o’s costs, capabilities, specifications, and specializations side-by-side:
Cost Comparisons: GPT-4 vs GPT-4o

Choosing GPT-4 vs GPT-4o
In most situations, GPT-4o is a stronger option than GPT-4, with several factors contributing to this:
Cost and Efficiency: GPT-4o offers substantial savings, charging $2.50 per million input tokens and $10 per million output tokens—far more affordable than GPT-4's $30 and $60 rates, respectively. For high-volume token usage, GPT-4o delivers cost savings without compromising functionality.
Speed: GPT-4o generates outputs up to twice as fast as GPT-4. GPT-4’s complex reasoning often results in slower output, while GPT-4o achieves a balance of speed and precision.
Multimodal Capabilities: With support for text, image, audio, and video inputs, GPT-4o provides far more versatility than GPT-4. For applications involving varied content types, GPT-4o is a clear winner.
Training Data: Trained on data up to October 2023, GPT-4o has a more recent understanding of current developments, which is beneficial in fields that rely on up-to-date information. GPT-4, trained on data through September 2021, may lack context on recent advances and trends.
Reasoning and Intelligence: While GPT-4 is recognized for nuanced reasoning, GPT-4o balances high-level intelligence with efficiency. It performs complex tasks well, and its cost and speed advantages make it suitable for a wider range of applications. Only in cases needing more intricate reasoning might GPT-4’s depth remain preferable.
Token Limit: GPT-4o’s output token limit of up to 16,384 tokens doubles that of GPT-4, enabling longer, more detailed responses—especially useful for content generation and large document summarization.
When Might GPT-4 Be Preferred?
There may be a few niche situations where GPT-4 may still be relevant:
- Specialized Problem-Solving: For tasks requiring especially nuanced analysis, like academic research or complex writing, GPT-4 may provide an edge in depth and detail. However the new o1 models are also great options.
- Legacy Systems: Established workflows already tailored to GPT-4 might make switching less convenient, especially if current systems are deeply integrated with the model.
Conclusion
For most applications, GPT-4o is the better choice, combining lower cost, higher speed, broader multimodal abilities, and more recent data training. Unless an application specifically benefits from GPT-4’s detailed reasoning or has existing GPT-4 dependencies, GPT-4o is likely the more efficient and versatile option.
