Today we’re launching Atla — the improvement engine for AI agents. Atla helps agent builders find and fix recurring failures. Instead of just surfacing traces, Atla automatically identifies your agent’s most critical failure patterns and suggests targeted fixes.
Super proud of @LisaAlazraki and team (@maximilianmozes @jaa_campos @yichern_tan) on the first of her two @cohere internship papers getting accepted to #EMNLP2025! 👏

🚨Life update:🚨 After 3 wonderful years, I’ve decided it’s time for me to move on from Cohere. I'm incredibly grateful to have been trusted with building out Cohere's post-training capabilities -- from our first Command Nightly models that topped the HELM leaderboard, to Command…
I’m building a new team at @GoogleDeepMind to work on Open-Ended Discovery! We’re looking for strong Research Scientists and Research Engineers to help us push the frontier of autonomously discovering novel artifacts such as new knowledge, capabilities, or algorithms, in an…

NeurIPS is pleased to officially endorse EurIPS, an independently-organized meeting taking place in Copenhagen this year, which will offer researchers an opportunity to additionally present their accepted NeurIPS work in Europe, concurrently with NeurIPS. Read more in our blog…
🎤 Meet our expert panelists! Join Albert Gu, Alisa Liu, Kris Cao, Sander Land, and Yuval Pinter as they discuss the Future of Tokenization on July 18 at 3:30 PM at TokShop at #ICML2025.
Really enjoyed discussing the state of AI benchmarking alongside Prof Mark Bishop, @IAmTimNguyen, Enzo Blindow & @ecsquendor at @MLStreetTalk's first in-person event in London yesterday. Looking forward to many more!
LLMs can be programmed by backprop 🔎 In our new preprint, we show they can act as fuzzy program interpreters and databases. After being ‘programmed’ with next-token prediction, they can retrieve, evaluate, and even *compose* programs at test time, without seeing I/O examples.
We’re looking for a Research Engineer / Scientist with a focus on Data Analysis and Evaluation to join the post-training team at Cohere! More details and application here: jobs.ashbyhq.com/cohere/6170371… Feel free to reach out if you'd like to know more!
Looking forward to sharing some of our recent research contributions at @MLStreetTalk's first London AI meetup 🤩

Kudos to @cohere for releasing 6 proper research papers in May alone, while publications of other western labs increasingly read like advertisements! I recently read the Command A technical report and it contains much more detail than other model reports. Looking at recent…
the command-a paper is one of my top 5 papers of the year for sure cohere.com/research/paper…
Massive congrats team Afri-Aya, really great work! 🤩
Join us to mark the end of Expedition Aya, our six-week global open-build challenge designed to accelerate ML research progress in multilingual, multimodal and efficiency✨ Top teams will present their key findings and innovations and our judges will select 5 winning projects🏆
Congrats to our Cohere colleagues for their paper “Improving Reward Models with Synthetic Critiques” being presented at NAACL this week! 🎉 Read the paper: arxiv.org/pdf/2405.20850 Work led by @Daniella_yz, @FraserGreenlee, @max_nlp, Phil Blunsom, @jaa_campos and @mgalle
Recently overheard @iclr_conf: influence functions for LLMs are useless. Poster #208 disagrees 🤔
At #ICLR2025? Come and see @LauraRuis present these amazing results on how LLMs exploit data in different ways to learn facts vs capabilities. Happening now at poster 208 in Hall 3! 🚀
