We’re heading to Google Next. (April 22-24) Come talk to us at booth #3722! If you’re building agents and want to debug things without guessing, come find us. arize.com/google-next...

Last week at the AI Builders meetup in Seattle, @jimbobbennett.dev spoke about boosting Claude Code performance using Prompt Learning. If you missed it, don't worry - Jim recorded a video of the session. youtu.be/ES43SEXArvk

Arize AX and Phoenix skills are now available in the awesome copilot repo, allowing GitHub Copilot users to install these with one command! All our individual skills are there, as well as plugins that bundle all the skills into a single install. awesome-copilot.github.com/plugins/?q=...

Congrats to Mistral on the Voxtral TTS release! mistral.ai/news/voxtra... We’ve been experimenting with evals + tracing for voice agents using OpenInference + Phoenix. Excited to see what builders create with it! (Try it out with Pipecat!)

Guess how many 🌟 Phoenix has on GitHub? Yes, this meme has been all over our internal slack today. github.com/Arize-ai/ph...

Most agent failures don't crash. They produce confident, wrong output that feeds the next agent in the pipeline. Now scale that across 100 agents per employee. Who's watching? arize.com/blog/100-ai...

New from Arize AX this week 🧵 Dashboard exports, smarter Alyx, SDK upgrades, and more. Full release notes → docs.arize.com/ax/release-...

Trying out evals can be hard if you work in a regulated industry and you can't send your traces to an external SaaS platform without paperwork and approvals. Phoenix is free, open source, and can run locally in a docker container! Your traces never leave your machine. arize.com/docs/phoeni...

The hardest part of AI platforms in banking? Serving 50 teams at different maturity levels without forcing one workflow. Phoenix plus AX solves this. arize.com/blog/why-ba...

deploying AI agents is easy. knowing if they're actually working? harder. join @ArizeAI + @M12VC at @GitHub HQ in SF on 3/31 with Amanda Foster and Nancy Chauhan for real talk on building and evaluating agents in prod 👇 luma.com/mxlgbdvw

Part 2 of our deep dive into how we built Alyx: context windows arize.com/blog/how-to... Once an agent starts running, context becomes the bottleneck fast.

We just released a new Prompt Tutorial for Arize AX: create, test, and optimize prompts with real data and evaluation. It's easy to tweak a prompt until it "feels" better without knowing if it actually improved. This tutorial walks you through a repeatable create → test → optimize workflow:

One thing that stood out from an experiment we ran recently: agents will climb whatever hill you point them at, but often can’t tell you if it’s the right hill.

Boost your coding agent's performance by 20% — without changing the model.

Arize AX now supports NVIDIA NIM as a native AI model provider! arize.com/blog/arize-...

TDD doesn't work for AI apps, instead you need EDD - eval-driven development. @jimbobbennett.dev gave a talk on this very topic at Azure AI Connect, part of the Global AI Community. Check out the video to learn how to do EDD, and for some very 🌶️ takes on AI. www.youtube.com/live/MC8yKi...

Last week we launched Alyx 2.0, the in-app AI engineering agent for Arize AX. Today we're taking it further. The AX CLI makes your Arize data machine readable so your coding agent can work with it directly. Blog: arize.com/blog/ax-cli... pip install arize-ax-cli
