I'm so thankful to have been part of this incredible team effort. The next generation of models will be truly incredible.

It is remarkable—and takes a moment to process—how quickly the next generation of models will accelerate our research, and breathe new life into old problems. This was an incredible project done by an incredible team (and model) in just a week. Ad Astra we go ✨

An internal version of Astra, @OpenAI’s next major model family, solved 10 major open problems in mathematics, quantum complexity, and theoretical computer science. We believe it will be a major step for scientific reasoning. openai.com/index/ten-advance…

The cost of generating the proofs for all 10 of these breakthroughs combined was under $2,000 at Sol API prices. We’re excited to see what scientists and researchers are able to create with our upcoming Astra models!

📢 We are excited to announce "#FMSD: 1st Workshop on Foundation Models for Structured Data" has been accepted to #ICML 2025! Call for Papers: icml-structured-fm-workshop.…

Open protocols like A2A and MCP are key to enabling the agentic web. With A2A support coming to Copilot Studio and Foundry, customers can build agentic systems that interoperate by design.

New preprint arxiv.org/abs/2502.05392 Open Challenges in Time Series Anomaly Detection: An Industry Perspective This is a vision paper about what I think it missing from current research in time series anomaly detection, and how it could align better with practical applications.

is that "agentic" enough🤣

Yes!

The data science revolution is getting closer. TabPFN v2 is published in Nature: nature.com/articles/s41586-0… On tabular classification with up to 10k data points & 500 features, in 2.8s TabPFN on average outperforms all other methods, even when tuning them for up to 4 hours🧵1/19

Today OpenAI announced o3, its next-gen reasoning model. We've worked with OpenAI to test it on ARC-AGI, and we believe it represents a significant breakthrough in getting AI to adapt to novel tasks. It scores 75.7% on the semi-private eval in low-compute mode (for $20 per task in compute ) and 87.5% in high-compute mode (thousands of $ per task). It's very expensive, but it's not just brute -- these capabilities are new territory and they demand serious scientific attention.

We are proud to release the first major version of DuckDB, v1.0.0, codenamed "Snow Duck". This version is a culmination of almost six years of research and development. Today we are shipping an innovative database system with a backwards-compatible storage format. Check out our announcement blog post: duckdb.org/2024/06/03/announ…

Columnar file formats like Parquet/ORC are ubiquitous. Our VLDB paper with @XinyuZeng218 + @huanchenzhang + @wesmckinn studies their internals. TLDR: They're not optimized for modern hardware. Something new is needed. Paper: vldb.org/pvldb/vol17/p148-ze… Code: github.com/XinyuZeng/Evaluat…

Not only is this the best model in the world, but it's available for free in ChatGPT, which has never before been the case for a frontier model.

GPT-4o is our new state-of-the-art frontier model. We’ve been testing a version on the LMSys arena as im-also-a-good-gpt2-chatbot 🙂. Here’s how it’s been doing.

Congrats to @AIatMeta on Llama 3 release!! 🎉 ai.meta.com/blog/meta-llama-… Notes: Releasing 8B and 70B (both base and finetuned) models, strong-performing in their model class (but we'll see when the rankings come in @ @lmsysorg :)) 400B is still training, but already encroaching GPT-4 territory (e.g. 84.8 MMLU vs. 86.5 4Turbo). Tokenizer: number of tokens was 4X'd from 32K (Llama 2) -> 128K (Llama 3). With more tokens you can compress sequences more in length, cites 15% fewer tokens, and see better downstream performance. Architecture: no major changes from the Llama 2. In Llama 2 only the bigger models used Grouped Query Attention (GQA), but now all models do, including the smallest 8B model. This is a parameter sharing scheme for the keys/values in the Attention, which reduces the size of the KV cache during inference. This is a good, welcome, complexity reducing fix and optimization. Sequence length: the maximum number of tokens in the context window was bumped up to 8192 from 4096 (Llama 2) and 2048 (Llama 1). This bump is welcome, but quite small w.r.t. modern standards (e.g. GPT-4 is 128K) and I think many people were hoping for more on this axis. May come as a finetune later (?). Training data. Llama 2 was trained on 2 trillion tokens, Llama 3 was bumped to 15T training dataset, including a lot of attention that went to quality, 4X more code tokens, and 5% non-en tokens over 30 languages. (5% is fairly low w.r.t. non-en:en mix, so certainly this is a mostly English model, but it's quite nice that it is > 0). Scaling laws. Very notably, 15T is a very very large dataset to train with for a model as "small" as 8B parameters, and this is not normally done and is new and very welcome. The Chinchilla "compute optimal" point for an 8B model would be train it for ~200B tokens. (if you were only interested to get the most "bang-for-the-buck" w.r.t. model performance at that size). So this is training ~75X beyond that point, which is unusual but personally, I think extremely welcome. Because we all get a very capable model that is very small, easy to work with and inference. Meta mentions that even at this point, the model doesn't seem to be "converging" in a standard sense. In other words, the LLMs we work with all the time are significantly undertrained by a factor of maybe 100-1000X or more, nowhere near their point of convergence. Actually, I really hope people carry forward the trend and start training and releasing even more long-trained, even smaller models. Systems. Llama 3 is cited as trained with 16K GPUs at observed throughput of 400 TFLOPS. It's not mentioned but I'm assuming these are H100s at fp16, which clock in at 1,979 TFLOPS in NVIDIA marketing materials. But we all know their tiny asterisk (*with sparsity) is doing a lot of work, and really you want to divide this number by 2 to get the real TFLOPS of ~990. Why is sparsity counting as FLOPS? Anyway, focus Andrej. So 400/990 ~= 40% utilization, not too bad at all across that many GPUs! A lot of really solid engineering is required to get here at that scale. TLDR: Super welcome, Llama 3 is a very capable looking model release from Meta. Sticking to fundamentals, spending a lot of quality time on solid systems and data work, exploring the limits of long-training models. Also very excited for the 400B model, which could be the first GPT-4 grade open source release. I think many people will ask for more context length. Personal ask: I think I'm not alone to say that I'd also love much smaller models than 8B, for educational work, and for (unit) testing, and maybe for embedded applications etc. Ideally at ~100M and ~1B scale.
