I’m excited to announce @DoeLabs coming out of stealth. @YuhuangOu and I are building vertical-specific AI tuned for industries still stuck with legacy software and nuanced workflows. Dental is just the start. Proudly backed by @ycombinator and an exceptional team.

The cost of intelligence is going to 0. We evaluated DeepSeek's new R1 model with @braintrustdata: -R1 generally beats o1 mini but lags behind o1 -The value is wild: o1 costs ~20x more for just ~4.5% better accuracy. Game-changing performance for the price.

Shipping reliable AI-powered apps isn't just about model performance – it's about delivering consistent value to users. That's why with LLM evals - response quality, task completion rates, and user satisfaction often matter more than pure model performance. Love how…

At @TechCrunch Disrupt earlier this week, I was fortunate to speak on the topic of what founders need to know when going from seed to Series A. When it comes to milestones, one of the things that what matters most is quality of the customer base - and @braintrustdata is a perfect…

One of the most common questions we hear from Braintrust users is: "I just ran an eval... what should I do next?" If you're wondering the same (or want to learn more about how many of our customers iterate), check out this blog post!

Evals used to be part of my daily life working on Google search. It's a profound change that with the advent of generative AI, running evals has become a part of mainstream software development. We wrote about what evals even are and our process for @v0 vercel.com/blog/eval-driv…

Braintrust is lightyears ahead of every other LLM eval tool we’ve tested (and there are lots). Absolute game changer for anyone trying to use LLMs in production. @braintrustdata

If yesterday was not enough Braintrust for you -- I went on No priors with @eladgil to talk about the journey so far, fundraise, and what's ahead. Was especially fun to talk about learnings from Impira, since Elad was an investor there too :)

"Omg did you see what this AI sai-" You bolt awake in your SoMA apartment. It is 2024. Your X feed is all Braintrust Series A. You are the CTO of a tech company, and you have changed your mind. The future cannot come to pass. The LLMs must be logged and evaled w @braintrustdata

The pace that @ankrgyl and @braintrustdata ship at is breathtaking. And with incredible taste and care for getting the abstractions for AI development right. They’ve quickly become the leading dev platform for AI, powering Stripe, Notion, Airtable, Instacart and more. Proud…

O1 now available in Braintrust playground. Interesting to see how this thing works -- it only supports temperature=1 and stream=false. Also interesting to see how many more tokens it consumes along the way towards a (more reasoned) answer.

Super excited to launch server-side online scoring in Braintrust. It's insanely easy to configure. Just pick scorers + sampling rate, and they run on your logs automatically. It supports LLM-as-a-judge, TS/Py code (UI or from your codebase via bundling), or any autoeval.
