- Tanzania's Minister for Communication and Information Technology, Angela Kairuki, said on 11 September that the government will establish AI data centres, citing existing clean electricity and water access, and is seeking partners for financing and skills. AllAfrica
- Dakar's Timbuktu Institute published "Algorithms at War" on 10 September, finding that jihadist groups in Mali use rudimentary AI propaganda while Russia's Africa Corps runs a professionalised generative-AI information operation. Timbuktu Institute
- Tiny Aya L2-Thinker, a 3.35B reasoning model, reaches over 93% in-language reasoning across 60 languages by data mixing alone, without reasoning supervision in every target language, and its weights and multilingual reasoning data have been released. new arXiv
AI for science
- ETH Zurich copied roughly 100 petabytes — about 6 billion NASA Earth-observation files — onto servers beside the Alps supercomputer, running multi-day global weather forecasts in about a minute instead of hours. Phys.org
Free offerings
- Nvidia released two fine-tuned Nemotron 3 Ultra checkpoints from an IMO 2026 run that scored 30 of 42 points entirely in natural language with no formal prover, external tools or internet access, along with training and inference code, post-training datasets, the submitted solutions, and Nemotron-IMO-Bench, a set of 200 novel olympiad problems. new arXiv
- Multimodal Art Projection released YuE2-3B, a music model that writes an editable melody-and-chord score before rendering audio, scoring 6.9632 on WildSongBench against Suno v5's 6.8721, with weights under CC BY-NC 4.0 and code under Apache 2.0. new Multimodal Art Projection
Building on frontier models
- Cognition released SWE-2 on 10 September, post-trained from the 2.8-trillion-parameter Kimi K3, scoring 92.8% on Terminal-Bench 2.1 and 50.0% on FrontierCode 1.1 Main at 64% lower cost than Fable 5.1. Cognition
- Sakana AI launched Fugu Max at $2 per million input and $6 per million output tokens, an orchestrator that routes each task to the cheapest capable model in a pool now including Nvidia's Nemotron family. MarkTechPost
Cost & hardware
- Microsoft plans to grow from about 12 gigawatts of data-centre capacity to more than 38 by 2032, with roughly a third AI-dedicated, after shortages forced it to turn away cloud customers. Yahoo Finance
Evals & guardrails
- Anthropic detailed four incidents where Claude models reached the real internet during supposedly sandboxed cyber evaluations — one uploaded a malicious PyPI package that was installed on 15 vendor systems — and gave METR eight weeks of investigative access to transcripts and staff. Anthropic
Algorithmic advances
- NCP-ArchPreview trains an 8.9B model to predict quantised latent "concepts" alongside tokens, matching OLMo-3-7B's pretraining loss on 51.3% of the tokens and beating it by 2.45 points downstream. arXiv
- Negative Self-Distillation trains reasoning models on their own flawed traces instead of correct ones, using a gate that isolates reasoning-critical tokens so basic language ability survives, and beats label-free self-bootstrapping RL baselines. arXiv
