When evaluating AI models, consider the following key performance indicators (KPIs) to make informed decisions:

* Quality: Subjective measure of AI model performance, often assessed through user feedback or expert evaluations.
* Output Speed: Tokens per second received while the model is generating tokens.
* Latency: Time to first token of tokens received, in seconds, after the API request is sent.
* Price: Cost per token, represented as USD per million Tokens.
* Context Window: Maximum number of combined input and output tokens that the model can handle.

By understanding these KPIs and the uses of the top AI models in 2025, investors can make more informed decisions about which models to invest in and how to leverage their capabilities for various industries and applications.
