Introducing NLLB-LLM2Vec! 🚀 We fuse the NLLB encoder & Llama 3 8B trained w/ LLM2Vec to create NLLB-LLM2Vec which supports cross-lingual NLU in 200+ languages🔥 Joint work w/ Philipp Borchert, @licwu, and @gg42554 during my great research stay at @cambridgeltl

SimBench accepted at #ICLR2026! A lot of the time in social simulations, the goal is not to predict what one specific person will say or do. It is to estimate how an entire group will respond, whether in pre-testing a real polling question, or in stress-testing a policy or intervention before running it in the real world.

Frontier LLMs can navigate complex websites, but are expensive and can't run locally. At the same time, small open models can't match the capabilities of commercial APIs. Can we close this gap with synthetic data? To answer this, we built Agent-as-Annotators (A3): a framework for agentic capability distillation, which is inspired by the human annotation process. Our new A3-Qwen3.5-9B model trained on just 2.3K trajectories matches the 3x larger Qwen3.5-27B on WebArena (41.5%) and nearly doubles the previous best open-weight SFT result (21.5%), despite never seeing WebArena tasks in during training.

LLM2Vec-Gen represents a major paradigm shift for embeddings/retrieval. Why encode the query when the LLM already knows what to look for and can directly produce an embedding for it? Best part: it’s self-supervised, and it does all of this while the LLM remains completely frozen. Think about it: "solve x² + 3x − 4 = 0" has zero reasoning in it. But the LLM's response does. By encoding the response, the embedding captures the reasoning --- and the better the LLM reasons, the better the embedding. This is why our results scale with model size. As LLMs get smarter, our embeddings automatically get better. LLM2Vec-Gen is also the first demonstration of the promise of @ylecun's JEPA for text embeddings. The alignment loss is JEPA — predict in representation space, not token space. The reconstruction loss goes beyond --- it keeps embeddings decodable. This paradigm shift opens new frontiers: 🔬 Can we build a full JEPA for language where the teacher and student are the same LLM? ⚡ Can LLMs reason in compressed space without ever generating text? 🤖 Can agents reason in compression tokens and carry that directly into retrieval? 💬 Can agents talk to each other in compression tokens instead of text --- dense, fast, and still human-readable? LLM2Vec-Gen is a first step toward all four.

Your LLM already knows the answer. Why is your embedding model still encoding the question? 🚨Introducing LLM2Vec-Gen: your frozen LLM generates the answer's embedding in a single forward pass — without ever generating the answer. Not only that, the frozen LLM can decode the embedding back into text. 🏆 SOTA self-supervised embeddings 🛡️ Free transfer of instruction-following, safety, and reasoning

Check out our new preprint on the superficial alignment hypothesis (SAH). 👇 We operationalize the SAH via the length of the shortest program that achieves a certain performance on a task, unifying previous views on the SAH and showing how post-training affects "superficiality".
tom@tvergarabrowne

first paper of the phd 🥳 the Superficial Alignment Hypothesis (SAH) argues that pre-training adds most of the knowledge to a model, and post-training merely surfaces it. however, this hypothesis has lacked a precise definition. we fix this.

🚨How do LLMs acquire human values?🤔 We often point to preference optimization. However, in our new work, we trace how and when model values shift during post-training and uncover surprising dynamics. We ask: How do data, algorithms, and their interaction shape model values?🧵

Instruction tuning unlocks incredible skills in LLMs, but at a cost: they become dangerously overconfident. You face a choice: a well-calibrated base model or a capable but unreliable instruct model. What if you didn't have to choose? What if you could navigate the trade-off? (1/8)
