Opik just surpassed 15,000 stars on GitHub⭐

Guess we're not stopping anytime soon.

Our R&D team just wrapped up an incredible week in Rome 🇮🇹

Remote-first doesn’t have to mean distant when you’re intentional about reconnecting as a team.

Here are some highlights from their week together!

Headed to #ICML2025? Come say hi! We’ll be on the expo floor all week.

✨ The real stars of the Comet community, captured in their natural habitat: napping on laptops, judging our code, and demanding snacks during Zoom calls.

Working for a remote-first company has its perks — like more time with our favorite four-legged coworkers.

🛡️Meet Opik Guardrails (Public Beta) - a lightweight, open-source toolkit for real-time LLM output management:

⚠️Topic moderation via a fine-tuned BART model
🔎 PII detection built on Presidio
💪 Support for third-party guardrail libraries

⚡LLMs are exciting to build with — until you remember you’re on the hook for what they say 😅

We’ve built something to catch the chaos before it hits your users 👇

Ships with 4 optimizers – including 3 developed in-house:

🧠 MIPRO – meta-prompt optimizer
🧪 Meta Prompter Optimizer – LLM works as a prompt engineer
🎯 Bayesian Few-Shot Optimizer – finds optimal few-shot examples
🧬 Evolutionary Optimizer

💡Prompt engineering doesn’t have to feel like an endless game of whack-a-mole.

Tweak → test → review → repeat — until you run out of time or patience.

We’ve built something to change that👇

🧵When building mental health apps powered by GenAI, evaluation is essential.

We’re proud to see Opik supporting Mirror, a free, research-backed app from the Child Mind Institute that helps teens manage stress & anxiety.

🚀 Tomorrow — we're diving into building scalable GenAI platforms with our friends from the Amazon SageMaker team.

It's not too late to register! 👉 engage.comet.com/comet-sagema...

🧑‍💻 GenAI models aren’t just “deploy and done.” Scaling them requires solid infrastructure and continuous monitoring to keep them performing.

Join this webinar on March 6th with our Head of Solutions Engineering & AWS engineers to learn how to do it right. Register 👉 engage.comet.com/comet-sagema...

🚀Generative AI is evolving fast -- keeping up isn’t easy.

Join us May 13-14th for Convergence 2025, a virtual conference on GenAI engineering.
