Simple beats complicated: We show that switching to a sliding-window attention mask with attention sinks (at no cost) beats linear attention post-training. Huge thanks to my collaborators Rhea Sukthanker, ‪Pashmina Cameron‬, and Emy Gervais. Paper: arxiv.org/abs/2608.28444

AI Weekly's analysis →
  • On the long-context reasoning tasks the paper cites (Needle-in-a-Haystack and BABILong), SWA scored 2 to 10 times higher than post-trained linear attention.
  • The authors argue linear-attention retrofits have not been properly compared to simpler baselines, and that SWA with sinks needs no post-training at all.
  • Their bottom-line recommendation is to switch to SWA rather than continue post-training linear models for inference memory savings.

if you're having trouble with Astra, it's probably old skills. Point your agent at these two URLs and use them to upgrade skills: 1. developers.openai.com/blog/rethink... 2. github.com/openai/codex...

AI Weekly's analysis →
  • OpenAI is telling developers to strip back the Skills descriptions and AGENTS.md instructions they carried over from GPT-5.6 Sol when moving to Astra.
  • The post says Astra runs tests on its own without being told to, so the old 'make sure to run the tests' instructions have become redundant noise.
  • Astra can stop earlier than Sol did and hand work back for review, so developers are told to define what 'done' looks like up front.

Google DeepMind article on 15 tears of Ai game research

Exploring new frontiers of AI and games research — Google DeepMind deepmind.google
AI Weekly's analysis →
  • Google DeepMind announced a research partnership with Fenris Creations, the studio behind EVE Online, to probe frontier AI capabilities inside the 20-plus-year-old space MMO.
  • The four capabilities in scope are named plainly: continual learning, memory, long-horizon planning, and complex multi-agent dynamics.
  • SIMA 2, powered by Gemini, now operates as an interactive companion across No Man's Sky, Valheim and Hydroneer, with an Aura Guidance system inside EVE.

I made a skill for Claude Code/Codex/etc. for selecting models based on Artificial Analysis reported benchmarks & costs I figure it'll be useful for letting models setup subagents well, based on the actual task at hand github.com/tkellogg/mod...

GitHub - tkellogg/model-selection: A skill for model selection github.com
AI Weekly's analysis →
  • The skill queries Artificial Analysis' API so subagents can rank available models by benchmark scores and cost before picking one for a task.
  • API calls are cached on a daily basis to stay under Artificial Analysis' free tier limit of 100 requests per day.
  • Install is a git clone into ~/.claude/skills, with an optional symlink into ~/.codex/skills for people running two agents.

GLM-5.3 is now open-weight. Their most capable model for agentic coding and cyber defense is now available to download, run, and customize. Weights: huggingface.co/zai-org/GLM-5.3 Tech blog: z.ai/blog/glm-5.3

z.ai
AI Weekly's analysis →
  • GLM-5.3 launched on August 14, 2026, keeping GLM-5.2's base and lifting Terminal-Bench 3.0 from 4.6 to 28.3 through post-training alone.
  • On CyberGym vulnerability discovery, GLM-5.3 scored 84.5%, slightly ahead of Claude Mythos 5 at 83.8% and GPT-5.6 Sol at 83.6%.
  • Z.ai says the model surfaced 2,436 vulnerabilities across 269 open-source projects, 1,097 rated critical or high, and delayed weights about two weeks.

Kimi K3 can now be run locally! ✨ The 1-bit model retains ~78.9% accuracy after we shrunk it from 1.56TB to 594GB (-62% size). Run on a Mac Studio + 128GB RAM device. Kimi K3 is the strongest open model to date. Guide: unsloth.ai/docs/models/... GGUF: huggingface.co/unsloth/Ki…
