Today I’m excited to announce the launch of Decagon Voice! Delivering enterprise-grade, hyper-realistic voice agents for customer interactions isn't easy. We're thrilled to partner with @elevenlabsio on this. This is a huge milestone in our agentic journey at @DecagonAI 🥳

Execute fast, then plan slow. @thejessezhang (CEO of @DecagonAI, a $1.5B AI unicorn) went through a true hero's journey. Painful first startup → intentional customer discovery → innovation in Agent Operating Procedures And, of course, the hill he'll die on: Commercial

Had a great time chatting with @patrick_oshag about @DecagonAI, startups, math, and more!

Great chat w @thejessezhang of @DecagonAI on @NoPriorsPod *AI agents & customer support *Hiring hardcore people *Counter-intuitive Advice for Founders *Agents vs agents in the future

Becoming an RL diehard in the past year and thinking about RL for most of my waking hours inadvertently taught me an important lesson about how to live my own life. One of the big concepts in RL is that you always want to be “on-policy”: instead of mimicking other people’s

And the evaluation loop never stops. Insights from every evaluation phase feed back into model selection, prompts, and agent logic, so performance keeps getting better over time.

Our framework includes: 🧠 LLM-as-judge scoring 📊 Ground truth benchmarking 🚦 Live A/B testing in production Each layer measures impact on accuracy, user empathy, and outcomes like CSAT and resolution rate.

Sharing a great post on how we approach evals at @DecagonAI! Every AI agent needs a rigorous evaluation engine. You can’t just test responses. We evaluate entire agent workflows to ensure real performance at scale https://t.co/oqOtTSB1ap

We’re excited to introduce Chai-2, a major breakthrough in molecular design. Chai-2 enables zero-shot antibody discovery in a 24-well plate, exceeding previous SOTA by >100x. Thread👇

When you’re leading, you talk about the work. When you’re trailing, you talk about the leader. And when you're spiraling, you make stuff up. 🙃

We first built these tools so our team could safely run experiments for enterprise customers. Now, we’re extending that power to every CX team: 🔄 A/B test live conversations 📊 Measure CSAT, deflection, & other metrics 🧠 Analyze results with stat sig tests

I’m excited to announce a key pillar of @DecagonAI’s product: our experimentation & A/B testing suite. CX teams can iterate on their AI agents faster, delivering fundamentally better customer experiences with every change. Read more:
