Join us tomorrow for a discussion around culture in AI! 🌱

💭We need more research that focuses on aspects beyond accuracy, especially in multilingual AI. 👉Help us explore the importance of culture in building and testing AI, with a few minutes of your time. Happy to have a chat as well with anyone who's interested in that space!

🌱Very proud of our team's latest release 😊 meet Tiny Aya, a massively multilingual model with 3.35B parameters. Tech report here: github.com/Cohere-Labs/...

At #Neurips2025 this week with @cohereforai.bsky.social 🤩 This is what brought me into research: the ✨Network Effect ✨ Let's build the next breakthrough together! #LabLegends

We’re thrilled to announce that some of our research will be presented at @emnlpmeeting.bsky.social next week! 🥳 If you’re attending the conference, don’t miss the chance to explore our work and connect with our team.

How well do LLMs handle multilinguality? 🌍🤖 🔬We brought the rigor from Machine Translation evaluation to multilingual LLM benchmarking and organized the WMT25 Multilingual Instruction Shared Task spanning 30 languages and 5 subtasks.

🌍Most multilingual instruction data starts as English and translation can’t capture cultural nuance or linguistic richness What if we optimized prompts instead of completions? That’s the focus of our most recent work on prompt space optimization for multilingual synthetic data🗣️

The next generation of open LLMs should be inclusive, compliant, and multilingual by design. That’s why we @icepfl.bsky.social @ethz.ch @cscsch.bsky.social ) built Apertus.

Let's do the venue justice. Very excited for today's multilingual workshops at #COLM2025 💙

Looking forward to tomorrow's #COLM2025 workshop on multilingual data quality! 🤩

Ready for our poster today at #COLM2025! 💭This paper has had an interesting journey, come find out and discuss with us! @swetaagrawal.bsky.social @kocmitom.bsky.social Side note: being a parent in research does have its perks, poster transportation solved ✅

We’re not your average lab. We’re a hybrid research environment dedicated to revolutionizing the ML space. And we’re hiring a Senior Research Scientist to co-create with us. If you believe in research as a shared, global effort — this is your chance.

💡A collaborative➕diverse team is key. In real life as in the LLM world 💪🦾 Check out our latest work that builds on this insight. 👇

Breaking into AI research is harder than ever, and early-career researchers face fewer chances to get started. Entry points matter. We started the Scholars Program 3 years ago to give new researchers a real shot — excited to open applications for year 4✨

While effective for chess♟️, Elo ratings struggle with LLM evaluation due to volatility and transitivity issues. New post in collaboration with AI Singapore explores why Elo falls short for AI leaderboards and how we can do better.

COLM 2025 is now accepting applications for: Financial Assistance Application -- docs.google.com/forms/d/e/1F... Volunteer Application -- docs.google.com/forms/d/e/1F... Childcare Financial Assistance Application -- docs.google.com/forms/d/e/1F... All due by July 31

🍋 Squeezing the most of few samples - check out our LLMonade recipe for few-sample test-time scaling in multitask environments. Turns out that standard methods miss out on gains on non-English languages. We propose more robust alternatives. Very proud of this work that our scholar Ammar led! 🚀

🚨LLM safety research needs to be at least as multilingual as our models. What's the current stage and how to progress from here? This work led by @yongzx.bsky.social has answers! 👇

🚧No LLM safety without multilingual safety - what is missing to closing the language gap? And where does this gap actually originate from? Answers 👇

Multilingual 🤝reasoning 🤝 test-time scaling 🔥🔥🔥 New preprint! @yongzx.bsky.social has all the details 👇

1/ Science is only as strong as the benchmarks it relies on. So how fair—and scientifically rigorous—is today’s most widely used evaluation benchmark? We took a deep dive into Chatbot Arena to find out. 🧵

🤓MT eyes on multilingual LLM benchmarks 👉 Here's a bunch of simple techniques that we could adopt easily, and in total get a much richer understanding of where we are with multilingual LLMs. 🍬Bonus question: how can we spur research on evaluation of evaluations?

Tired of messy non-replicable multilingual LLM evaluation? So were we. In our new paper, we experimentally illustrate common eval. issues and present how structured evaluation design, transparent reporting, and meta-evaluation can help us to build stronger models.

📖New preprint with Eleftheria Briakou @swetaagrawal.bsky.social @mziizm.bsky.social @kocmitom.bsky.social! arxiv.org/abs/2504.11829 🌍It reflects experiences from my personal research journey: coming from MT into multilingual LLM research I missed reliable evaluations and evaluation research…

🚀 We are excited to introduce Kaleidoscope, the largest culturally-authentic exam benchmark. 📌 Most VLM benchmarks are English-centric or rely on translations—missing linguistic & cultural nuance. Kaleidoscope expands in-language multilingual 🌎 & multimodal 👀 VLMs evaluation

☀️ Summer internship at Cohere! Are you excited about multilingual evaluation, human judgment, or meta-eval? Come help us explore how a rigorous eval really looks like while questioning the status quo in LLM evaluation. I’m looking for an intern (EU timezone preferred), are you interested? Ping me!

Command🅰️ technical report is out. Information-dense. Detailed. Pretty. Simply A+! 💎: cohere.com/research/pap...

A bit of a mess around the conflict of COLM with the ARR (and to lesser degree ICML) reviews release. We feel this is creating a lot of pressure and uncertainty. So, we are pushing our deadlines: Abstracts due March 22 AoE (+48hr) Full papers due March 28 AoE (+24hr) Plz RT 🙏

💬The first Q&A starts in a few hours. 🔔Also, a reminder to create your Open review profile if you haven't already. Non-institutional accounts require a verification process that can take time. One week till the abstract deadline!

We’re excited to bring back Expedition Aya 🌍 A 6-week open build challenge to accelerate ML research progress in multilingual, multimodal and efficiency. Join us to expand the world that AI sees.

✨ Multilingual language modeling meets WMT✨ very exciting opportunity to get WMT-style evaluations for MLLMs: unseen tests, human evaluation, meta-evaluation, and that for multiple languages and tasks. Almost too good to be true! 🤩

COLM's @juliakreutzer.bsky.social and @abosselut.bsky.social will hold two paper submission Q&A sessions. We run a simple process, but figured this can help authors, especially first-time authors. March 12: dateful.com/eventlink/14... March 13: dateful.com/eventlink/83... Plz RT 🙏

Guess what? The jubilee 🎉 20th iteration of WMT General MT 🎉 is here, and we want you to participate - as the entry barrier to make an impact is so low! This isn’t just any repeat. We’ve kept what worked, removed what was outdated, and introduced many exciting new twists! Among the key changes are:

Who will triumph - Aya Vision or its creators? 🤼 We challenged the research team behind Aya Vision to mystery object trivia. 💎🌽🧈 www.youtube.com/watch?v=iQEd...

✨👓 Aya Vision is here 👓✨ A multilingual, multimodal model designed to understand across languages and modalities (text, images, etc) to bridge the language gap and empower global users!
