We’re excited to share BrainWideBench, a new benchmark for evaluating how models of neural activity generalize across animals and tasks! A major bottleneck in modeling neural data today is rigorous and standardized evaluation. Modelling techniques need to be tested under multiple regimes and downstream tasks. 📄 Check out the paper here! arxiv.org/abs/2609.22064 Special shoutout to @alx_adr, who co-led this work with me and contributed equally as co-first authors!

Josh Siegle and I are thrilled to be chairing the first workshop on "Bridging the gap between cell types and spike trains"! We see this as the key link between population-level descriptions of dynamics and real mechanistic understanding from cell types. celltypestospikesworkshop.gi…

I’ll be presenting POSSM at #NeurIPS2025 tomorrow, together with @averyryoo. Come by our poster for cute stickers and to chat about neural decoding, BCIs, and foundation models for neuroscience! 🧠🤖 🗓️ Dec 3rd 🕚 11:00 am – 2 pm 📍 Poster #2000 Exhibit Hall C,D,E
New preprint! 🧠🤖 How do we build neural decoders that are: ⚡️ fast enough for real-time use 🎯 accurate across diverse tasks 🌍 generalizable to new sessions, subjects, and species? We present POSSM, a hybrid SSM architecture that optimizes for all three of these axes! 🧵1/7

Excited to share our #NeurIPS2025 work: NuCLR, a framework for learning neuron-level representations 🧠 These embeddings capture the biological identity of neurons and work out-of-the-box on new animals; no finetuning needed 💃 This offers some of the first evidence that large-scale neuroscience models can truly generalize across animals. Paper: arxiv.org/abs/2512.01199 Code: github.com/nerdslab/nuclr If you are at NeurIPS in San Diego, come find us at Poster Session 5 (11am-3pm PT, Exhibit Hall C,D,E, # 2107) 🎉 1/x 🧵

How can we make progress in developing a general model of neural computation rather than a series of disjointed models tied to specific experimental circumstances, ask @evadyer and Blake Richards @tyrell_turing in the latest entry in our NeuroAI series. thetransmitter.org/neuroai/a…

What will a foundation model for the brain look like? We argue that it must be able to solve a diverse set of tasks across multiple brain regions and animals. Check out our preprint where we introduce a multi-region, multi-animal, multi-task model (MtM): arxiv.org/abs/2407.14668

This might be the secret to breaking through the next plateau in deeper reasoning, planning and retrieval capabilities for AI agents 🤔 LGGMs (large generative graph models) are on the rise! While @Adobe and @intel were first at it with LGGMs, researchers at @GeorgiaTech have trained their own model called GraphFM (links below). It’s important that more progress is made on this front to improve causal grounding with graph-based retrieval, DAG generation for LLM Compiler like planning mechanisms and for graph-based self-discovery + continual learning agents with graph-based CLIN to further enhance reasoning, decision-making and environmental grounding for AI agents. Existing implementations of knowledge graph generation (like with GraphRAG) rely on LLMs to define entities/relationships which isn’t always accurate... moving to LGGMs may finally unlock the potential of graphs for many of the use-cases outlined above. Excited to see some infrastructure providers in the next 6-12 months start scaling and offering these kinds of models which I think will play a critical role in making agents substantially more reliable when combined with similar design patterns as linked to below - and especially when combined with optimization frameworks like DSPy and Agent Symbolic Learning. Have a feeling that domain-specific SGMs (small graph models) or frameworks to build your own SGMs for distributed agentic systems will be next to come… Read for yourself, connect the dots and thank @divyyansha1115, @mehdiazabou, @vinam_arora and @evadyer for their amazing work! 🔥 GraphFM by Georgia Tech: arxiv.org/abs/2407.11907 LGGMs by Intel & Adobe: arxiv.org/pdf/2406.05109 LGGM Code, Demo & Datasets: lggm-lg.github.io/ Self Discover: arxiv.org/abs/2402.03620 CLIN: arxiv.org/abs/2310.10134 LLM Compiler: arxiv.org/abs/2312.04511 DSPy: github.com/stanfordnlp/dspy Agent Symbolic Learning: arxiv.org/abs/2406.18532

Check this out! So excited to share our recent work in building foundation models for graphs!
Excited to share our Graph Foundation Model, 🌐 GraphFM, trained on 152 datasets with over 7.4 million nodes and 189 million edges spanning diverse domains. 🚨 Check out our preprint for GraphFM where we test how our model scales with data and model size, and show efficient finetuning on new datasets.

Have you ever done a dense grid search over neural network hyperparameters? Like a *really dense* grid search? It looks like this (!!). Blueish colors correspond to hyperparameters for which training converges, redish colors to hyperparameters for which training diverges.

Today, I am very proud share what we have been working on for the last 14 months. ✨ Introducing Aya -- a new state-of-art for massively multilingual models. 🔥🎉
Today, we’re launching Aya, a new open-source, massively multilingual LLM & dataset to help support under-represented languages. Aya outperforms existing open-source models and covers 101 different languages – more than double covered by previous models. cohere.com/research/aya
