“Arize observability is pretty awesome!”
Andrei Fajardo
Founding Engineer, LlamaIndex
"We found that the platform offered great exploratory analysis and model debugging capabilities, and during the POC it was able to reliably detect model issues."
Mihail Douhaniaris & Martin Jewell
Senior Data Scientist and Senior MLOps Engineer, GetYourGuide
“Our big use case in Arize was around observability and being able to show the value that our AIs bring to the business by reporting outcome statistics into Arize so even non-technical folks can see those dashboards — hey, that model has made us this much money this year, or this client isn’t doing as well there — and get those insights without having to ask an engineer to dig deep in the data.”
Lou Kratz, PhD.
Principle Research Engineer, BazaarVoice
"Working with Arize on our telemetry projects has been a genuinely positive experience. They are highly accessible and responsive, consistently providing valuable insights during our weekly meetings. Despite the ever-changing nature of the technology, their guidance on best practices—particularly for creating spans to address emergent edge cases—has been incredibly helpful. They've gone above and beyond by crafting tailored documentation to support our implementation of Arize with OpenTelemetry, addressing specific use cases we've presented."
Priceline
“You have to define it not only for your models but also for your products…There are LLM metrics, but also product metrics. How do you combine the two to see where things are failing? That’s where Arize has been a fabulous partner for us to figure out and create that traceability.”
Anusua Trivedi
Head of Applied AI, U.S. R&D, Flipkart
"From Day 1 you want to integrate some kind of observability. In terms of prompt engineering, we use Arize to look at the traces [from our data pipeline] to see the execution flow … to determine the changes needed there."
Kyle Weston
Lead Data Scientist, GenAI, Geotab
"The U.S. Navy relies on machine learning models to support underwater target threat detection by unmanned underwater vehicles ... After a competitive evaluation process, DIU and the U.S. Navy awarded five prototype agreements to Arize AI [and others] ... as part of Project Automatic Target Recognition using MLOps for Maritime Operations (Project AMMO).”
