What Is an AI Model?
An AI model is a type of computer program trained on large datasets to recognize patterns, make predictions and generate outputs with minimal human intervention. The process begins with human researchers feeding the model relevant data that has been cleaned and prepared ahead of time. Then, they apply algorithms — sets of mathematical rules and instructions — that help the model learn how to identify specific patterns within the training data. Once an AI model has been tested for accuracy and properly trained, it should be able to generalize what it has learned and analyze new, unseen data on its own.
AI models are designed to perform specific tasks, with more advanced models handling more complex problems. Depending on how they’ve been trained, AI models can do anything from recognizing faces in video footage to translating text into other languages.

What Is the Best AI Model?
It’s impossible to designate an AI model as “the best” for various reasons. For one, the benchmarks used to compare these models are inherently broken and not very effective in general. Even when companies do manage to present helpful comparisons, the differences between models can be so slim that they’re inconsequential.
And the AI race continues to provide improved AI technologies — the models of today are merely stepping stones for even more powerful systems on the horizon. So, when in doubt, just pick the AI model that most closely fits your particular needs, but keep an eye out for any upcoming models that could give you an even greater competitive advantage.
Frequently Asked Questions
How do AI models differ from one another?
AI models differ from one another based on a variety of factors, including size, architecture, training data, capabilities, speed, accuracy and cost.
What are AI benchmarks?
Benchmarks are standardized tests researchers and companies can use to evaluate a given AI model’s performance on specific tasks, such as math, reasoning and coding. Commonly used benchmarks include MMLU, HumanEval and SWE-Bench.
How do I choose the best AI model?
To find the best model for you, consider factors like what task you want to perform (content creation, code generation, customer support, image recognition, etc.), the level of accuracy you need, your budget and the level of data security you require. You can also fine-tune models on your own data to improve their performance on more specialized tasks.
