GLM-5.2: Built for Long-Horizon Tasks huggingface.co

GLM-5.2 is probably the most powerful text-only open weights LLM simonwillison.net

Chinese AI lab Z.ai released GLM-5.2 to their coding plan subscribers on June 13th, and then yesterday (June 16th) released the full open weights under an MIT license. Similar in size to their previous GLM-5 and GLM-5.1 releases, this is 753B parameter, 1.51TB monster - with 40 active parameters (Mixture of Experts). GLM-5.2 is a text input only model - Z.ai have a separate vision family most recently represented by GLM-5V-Turbo , but that one isn’t open weights. GLM-5.2 has a 1 million token c…

AI coding agents taught robots how to install GPUs and cut zip ties arstechnica.com

Nvidia’s self-improvement program hands robot training over to teams of AI coding agents, which have already taught machines to install GPUs and snip zip ties. The setup closes the loop between code generation and physical task learning without human supervision at each step.

From the Hugging Face Hub to robot hardware with Strands Agents and LeRobot huggingface.co

A new Amazon-Hugging Face integration wires Strands Agents into LeRobot so models pulled from the Hub run directly on physical robots. The pipeline shortens the path from a checkpoint download to on-device control, targeting developers building agent-driven robotics stacks.

Quoting Charity Majors simonwillison.net

Charity Majors argues the economics of software flipped last year, with AI making code generation effectively free and instant. Lines once curated and reused are now disposable and regenerable, a shift she says demands more engineering discipline, not less.

“Dangerous” AI models are coming no matter what arstechnica.com

Frontier labs and open-weight releases are converging on models that can autonomously discover and exploit vulnerabilities, and containment is slipping out of reach. Anthropic’s Claude work features in the reporting as a case study in how fast offensive capability is normalizing.

How to turn off AI in your Google Docs techcrunch.com

Google Docs users tired of Gemini pop-ups can disable the assistant through Workspace settings, killing the inline suggestions and sidebar prompts. The walkthrough covers both personal accounts and admin-managed domains where IT controls the toggle.

Z.ai’s open-weights GLM-5.2 beats GPT-5.5 on multiple long-horizon coding benchmarks for 1/6th the cost

ofox.ai self-host guide ofox.ai

Self-hosting becomes more economical than Z.ai’s API once a team exceeds roughly 3,000 prompts per day; an 8x H200 node runs $30–$50/hour and a 1M-token KV cache adds 35–50 GB at 4-bit, up to 200 GB at 16-bit.

None of us are running it at home without an enterprise cluster, but the distillation potential here is massive.

AI Weekly — Artificial Analysis Intelligence Index aiweekly.co

GLM-5.2 tops the open-weights Intelligence Index with a score of 51, ahead of DeepSeek V4 Pro (44) and Kimi K2.6 (43), but is notably token-hungry, consuming up to 43k output tokens per task.

ainew.jp coverage of Simon Willison’s review news.ainew.jp

It’s a self-contained fully animated SVG, and the animations aren’t broken!… Very impressive. [On the opossum-on-an-e-scooter prompt] a step down from GLM-5.1, with no animations and weird background gridlines.

Latent.Space AINews latent.space

GLM-5.2 treats the system prompt like a spec… ranked as the top frontend coding model behind only the proprietary Claude Fable 5 on Code Arena WebDev.

Any-point Trajectory Modeling (RSS 2024 paper) roboticsproceedings.org

ATM extracts control-specific guidance from human or cross-embodiment videos by predicting trajectories for arbitrary points, demonstrating an 80% improvement in success rates over traditional video pre-training baselines by providing closed-loop future trajectories as subgoals.

Ai2 — MolmoPoint blog allenai.org

MolmoPoint moves away from external coordinate formats, instead tying pointing directly to the model’s internal visual representation using rotary embeddings… MolmoPoint-8B reaches 70.7% on Point-Bench, surpassing specialized pointing models like Poivre.

RT-Trajectory project page (Google DeepMind) rt-trajectory.github.io

RT-Trajectory allows users to provide 2D sketches or ‘human-drawn’ trajectories, which the model uses to reduce semantic ambiguity in language instructions.

NVIDIA Developer Blog — World-Action Models developer.nvidia.com

Newer WAMs leverage pretrained video backbones to ‘imagine’ future states before executing a motion… addressing the ‘grounding wall’ where models previously struggled to translate linguistic concepts into precise spatial trajectories.

EmergentMind — Diffusion as Shader (DaS) emergentmind.com

DaS ensures 3D consistency but cannot currently represent ‘emerging’ objects that were not present in the initial frame; models still struggle with hallucinated content in occluded regions and failing to follow trajectories when they conflict with internal physical priors.

Robotics Center — VLA Models Comparison 2025 roboticscenter.ai

Large VLAs typically run at low frequencies (~6 Hz), often insufficient for high-speed industrial tasks… long-horizon tasks frequently see success rates drop below 50%.

Synscribe census (June 18, 2026) synscribe.com

An independent census conducted on June 18, 2026 analyzed 39 major domains, including all eleven founding members of the ARD working group. The survey found zero discoverable ai-catalog.json files in the wild.

GoDaddy’s Agent Name Service (ANS) uses ACME-based domain validation and immutable Transparency Logs to issue cryptographic certificates for agents… before an orchestrator hands data to an agent or tool, it can independently verify the publisher’s identity.

OWASP Top 10 for Agentic Applications 2026 (via Help Net Security) helpnetsecurity.com

‘Registry Poisoning’ (ASI_04) has been formally introduced as a critical risk… ‘AI Hallucination Squatting’ has emerged where agents generate fake package names which attackers register on public repositories to plant dormant attack vectors.

LetsDataScience letsdatascience.com

The primary authority over the ai-catalog.json format currently resides with the Linux Foundation’s AI Catalog Working Group… published under Apache 2.0… not yet an official IETF or W3C standard.

Publii guide to llms.txt getpublii.com

Community adoption of llms.txt has been rapid, with over 800,000 sites implementing it by early 2026… ARD for finding what a site can do, and llms.txt for reading how to use it — they form a complementary stack.

Reddit r/GeminiAI discussion reddit.com

Federated registries could easily become centralized monopolies, where the ranking and indexing of capabilities are controlled by the registry provider rather than the end user… developers are wary of ARD becoming ‘yet another layer’ that adds fragmentation rather than resolving it.
