What do you like best about Arize AI?Custom Code Evaluator and Live tracing projects. Review collected by and hosted on G2.com.What do you dislike about Arize AI?when you choose to run 10/20 rows in the playground by selecting the dataset. Instead of first 10 rows it randomly runs any 10 examples. Which doesn't helps with the consistency in running the evals Review collected by and hosted on G2.com.
What do you like best about Arize AI?I like how accessible it is to view traces, spans, and sessions, along with the evaluation methods. It’s also helpful that I can access them either through the UI or even offline. The filtering of data also makes it very easy to view the required spans, traces and sessions. Also the trace tree feature is very helpful to view the kind of each span. Review collected by and hosted on G2.com.What do you dislike about Arize AI?There’s really nothing to dislike. The only thing I’d change is making the filtration a bit simpler, because it took me a while to understand. Once I got how the filtration works, though, I was able to connect without any issues.

What do you like best about Arize AI?The product is crisp and I understood how it operates through courses. It has almost got everything for model monitoring and other important features. It helps in all the for ML operations. Review collected by and hosted on G2.com.What do you dislike about Arize AI?Arize AI, if I am not wrong is like a dashboard. It would have been better if there was an API sort of thing where we can leverage the features through a package. Review collected by and hosted on G2.com.
