Super proud of @LisaAlazraki and team (@maximilianmozes @jaa_campos @yichern_tan) on the first of her two @cohere internship papers getting accepted to #EMNLP2025! đź‘Ź.
This is accepted to EMNLP Main! Looking forward to presenting it in Suzhou 🎉.

🚨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

Some of the real-world challenges of building for representation.
This is one of my favorite sections in the Aya dataset paper. It is towards the end of the paper, so probably isn't read often. It speaks to how the end breakthrough was completely intertwined with the geo-reality experienced by independent researchers around the world.

Looking forward to sharing some of our recent research contributions at @MLStreetTalk's first London AI meetup 🤩.
We are running our first physical event in London on 14th July! We have Tim Nguyen @IAmTimNguyen from DeepMind and Max Bartolo @max_nlp from Cohere and Enzo Blindow (VP of Data, Research & Analytics) at @Prolific joining us. Not many seats for the first one.

Another side finding was that in some cases, incoherent preambles also led to improved performance. This has exciting implications for other conditioning token sequences such as reasoning traces.

Can LLMs be incentivised to generate token sequences (in this case preambles) that condition downstream models to improve performance when judged by reward models? Yes! âś….
Thrilled to share our new preprint on Reinforcement Learning for Reverse Engineering (RLRE) 🚀. We demonstrate that human preferences can be reverse engineered effectively by pipelining LLMs to optimise upstream preambles via reinforcement learning 🧵⬇️

Massive congrats team Afri-Aya, really great work! 🤩.
Huge Win Today 🎉🎉 Our team “Afri-Aya” just won this year’s @cohere Aya Expedition. Our work is focusing on 1) curating and evaluating vision dataset then 2) Finetuning the Aya vision model for underrepresented languages in Africa. I represented my beloved Sierra Leone with Krio
