Improved AI workload visibility has reduced manual planning and supports reliable monitoring
I believe Arize AI can be improved with integration with some of the other providers. It works really well with some of the major frontier AI models, but I think the API should be exposed as much as possible to non-frontier models as we go along. I think integration can be improved. It is not a major challenge, but it requires some TKI understanding along with an understanding of Arize AI from an API perspective, so it could be improved with more detailed or better user guides. Except for exposing some of the APIs to some non-major AI frontier models, I would say we are pretty much satisfied with Arize AI.

Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Arize AI stands out to me because of its observability and traceability and ease of use; you can click and you are good to go, and it makes you catch bugs and issues very early before debugging while helping you monitor your models in production."
"Since using Arize AI, development speed improved by 50% to 60% and I saved approximately two days on each release on the testing and evaluation."
"Arize AI has positively impacted my organization by reducing most of our manual work, shifting us to complete automation, reducing working hours, and allowing us to focus more on accuracy with less chance of mistakes."
"I have found Arize AI really helpful compared to other conventional observability and monitoring tools."
"Arize AI has made leadership more comfortable with introducing AI features by providing better visibility into failures and reducing unexpected issues in production."
"In my day-to-day work, monitoring is the main focus, and while there are many other tools like Prometheus and Grafana for monitoring, for ML specific use cases, I think Arize AI is the best."
"Our timely actions, aided by Arize AI, have allowed us to report results with over 99% accuracy, proving it quite useful."
"Arize AI has positively impacted my organization as the answers are more accurate and agent quality has improved dramatically."
"Datadog has significantly improved our organization’s visibility into system performance and application health, and the real-time dashboards and alerting capabilities have helped our teams detect issues faster, reduce downtime, and improve response times."
"Since adopting Datadog, it has reduced the manual effort by around seven to eight hours per week, making the process completely automated."
"Datadog has alerting events and metrics all in one place; this was a huge plus, other solutions were trying to treat monitoring as a multi-faceted problem, while Datadog treated it as one problem."
"We like the distributed tracing and flame graphs for debugging. This has been invaluable for us during periods of high traffic or red alert conditions."
"The most valuable features of Datadog are the flexibility and additional features when compared to other solutions, such as AppDynamics and Dynatrace. Some of the features include AI and ML capabilities and cloud and analysis monitoring"
"It really provides a lot of visibility in terms of how our software is working, and if there are any problems, it surfaces them right away and we get alerts in Slack, making it an essential tool for a company that provides software as a service."
"Enabling customers to manage their content in a fast, reliable, and highly user-friendly setup has been critical to our success."
"It brings in observability, monitoring, and alerting capabilities - all of which we need to operate at scale."
 

Cons

"We mostly use Arize AI for the ML side, but in my experience, Arize AI lacks on the GenAI side."
"I think integration can be improved."
"The evaluation workflow lacks depth in comparison to competitors, which generally rely on traditional ML frameworks."
"I think Arize AI's UI could be better because it's pretty hard to understand."
"More end-to-end architecture examples would be beneficial as current technical documentation is solid, but more practical examples are desired."
"Arize AI can add more functions."
"I think Arize AI lacks some capabilities like a versioning system."
"I think we can improve its interface."
"It is very difficult to make the solutions fit perfectly for large organizations, especially in terms of high cardinality objects and multi-tenancy, where the data needs to be rolled up to a summarized level while maintaining its individual data granularity and identifiers."
"Users need to be aware of licensing control. With autodiscovery, the product can begin to come at a high cost."
"It lacks consistency in the APIs."
"Datadog has a lot of documentation, but a lot of that documentation assumes you know how the service works, which can lead to confusion."
"I believe Datadog could be improved because sometimes it's not the most user-friendly, and when monitors have a new metric or a service that no longer needs to be monitored, it remains in the system."
"Customer support has been ok, yet not great. We've had ticket resolution drag on for weeks."
"Datadog is too pricey when compared to its competitors, and this is something that its always on my mind during the decision-making process."
"Datadog is expensive."
 

Pricing and Cost Advice

Information not available
"Datadog does not provide any free plans to use the solution. When I start with a proof of concept it would be sensible to have a free plan to test the tool and check whether it fits the requirements of the project. Before the production stage, it is always good to have a free plan with some limited features, number of requests, or logs."
"​Pricing seems reasonable. It depends on the size of your organization, the size of your infrastructure, and what portion of your overall business costs go toward infrastructure."
"While it is an expensive product, I would rate the pricing level at four out of five."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"It has always scaled for us. Cost scales up too, but that is not necessarily a bad thing. It's reasonable for what they're providing."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"I am not satisfied with its licensing. Its payment is based on the exported data, and there was an explosion of the data for three or four weeks. My customer was not alerted, and there was no way for them to see that there has been an explosion of data. They got a big invoice for one or two months. The pricing model of Datadog is based on the data. The customer was quite surprised about not being alerted about this explosion of data. They should provide some kind of alert when there is an increase in usage."
"Our licensing fees are paid on a monthly basis."
