This Week in All Things AI covers key developments in models, agents, tools, infrastructure, and policy curated from discussions in the All Things AI Telegram group.
If you follow AI for work, research, investing, or just to understand where the technology is heading, this weekly brief is a concise way to scan the most important launches, risks, and resources in a few focused minutes.
During the week of May 31 to June 6, 2026, the AI landscape was defined by a wave of model releases, escalating cost concerns, and infrastructure advances. Major model launches came from MiniMax (M3), NVIDIA (Nemotron 3 Ultra), Alibaba (Qwen3.7-Plus), Google DeepMind (Gemma 4 12B), and Microsoft (seven MAI models), while Anthropic reported Claude now authors 80% of its own codebase and OpenAI updated ChatGPT's memory system. On the cost front, an unnamed firm's $500M Claude AI bill dominated headlines, spurring broader cost-control moves — Uber capped AI spending at $1,500 per employee monthly, and tools like Factory Router and Lindy's migration to DeepSeek v4 demonstrated significant savings. Infrastructure and tooling saw updates from Perplexity's "Search as Code," SambaNova's disaggregated inference, Supabase's $500M raise, OpenAI's Codex plugins, Grok Composer 2.5, and Scaledown.ai launch of small-language-model services for compression and summarization
The sections that follow walk through these items day by day, with short context and links so you can dive deeper into the pieces most relevant to your work or interests.
Unnamed firm racks up $500M Claude AI bill in one month
An unnamed enterprise client spent more than $500 million in just 30 days on Anthropic's Claude AI platform after failing to set any usage limits or spending caps for employees, according to an Axios investigation published on May 28. The disclosure, made by an AI consultant whose client generated the bill, may represent one of the costliest IT governance failures on record

Some discussion between me and Anya Shapina related to Composer2-5 model availablility via Grok
=====
Anya
IMO Grok is the most under-appreciated model. I know, my comment is out of context (I haven't used Grok Build enough). But just as a model, it roxx! Testing very complicated agents and workflows across models and it kinda wins most scenarios. In my experience, it excels at walking and chewing gum at the same time (while also looking for shadows lurking behind bushes) - this is where most models fail for me. Not to mention native search, X, and Reddit. Anyone else in my Grok camp? Sorry, Elon haters :)
Yusuf
Which model of Grok Anya ? I think grok-build-0.1 is highy underrated and really look forward to the release of v9. Elon has a tendency to hype up particularly given the SpaceX IPO but the pace of updates of Grok Build CLI is relentless
Anya
Grok 4.3 - in my specific tests powering Agents (Not Grok Build which you post was about; look fwd to reporting on this later). Grok 4.3 - Strongest agentic tool calling + lowest hallucination rate in the lineup, from what I know. Worked for me.

Factory Router automatically selects the best AI model for each task in the Droid coding agent, slashing costs by 20-25% while matching 99% of premium performance on benchmarks like Terminal-Bench 2. It routes routine edits to cheaper models and escalates complex work to heavy-hitters like Claude Opus 4.7, even switching providers mid-task for reliability. Tech leaders like Keith Rabois and Garry Tan praised it as essential for enterprises facing rising AI bills, with CEO Matan Grinberg comparing it to hiring the right expert instead of Einstein for basic math. Currently in private preview for CLI and desktop users.
FWIW, Droid from Factory is one of my goto model-agnostic harness alongside Opencode Go. Very good Claude Code compatability in terms of support for skills, plugins, hooks, sub-agents etc and one of the best if not the best context management I've come across

Google DeepMind releases Gemma 4 12B, a lightweight 12B-parameter multimodal model under Apache 2.0 license designed to run locally on laptops with just 16GB VRAM or unified memory.
It introduces an encoder-free unified architecture where vision uses a tiny 35M-parameter embedding module and audio projects raw signals directly into the LLM backbone, eliminating separate encoders for efficiency.
Delivers advanced reasoning and multimodal capabilities nearing the larger Gemma 4 26B model's benchmarks, with native 256K context, MTP drafters, and immediate support across Hugging Face, Kaggle, llama.cpp, MLX, and vLLM.

At Computex, SambaNova demoed a “disaggregated inference” architecture where GPUs handle prefill and their RDUs handle decode, yielding faster, cheaper long-horizon agent workloads than GPU-only setups, and they now have this running in production-style environments with partners like VC2 and Together AI.

Response from Anya Shapina

I believe Supabase (and possibly its philosophical rival Convex) will be some of the biggest winners in the AI race. I use it as the shared memory and persistent backend of my multi-agent system - it's everything to my project, and all other projects I've ever built. But then there is the Goliath Convex with its built-in support for AI Agents... and NO SQL (love/hate?). Which camp are you people in?

I've not used Lindy but have heard good things about it from others. For those unaware of Lindy, it describs itself productivity and automation platform that positions itself as an "AI executive assistant" or "AI employee." It is particularly strong for professionals who want proactive help with email, meetings, and calendar management.
Saw this post from Flo Crivello, founder of Lindy who migrated 100% of its traffic to DeepSeek v4 from Anthropic models, reporting millions in cost savings alongside performance improvements on core use cases. The switch required building substantial new infrastructure and internal tooling, described as 100x more work than anticipated, emphasizing the value of swappable model architectures.
Saves us millions of $ and we're actually seeing an *increase* in performance on many core use cases. Transformative for the business.
Response from Ms Macarena Correa to a post dated 30th May 2026 about the announcement of Kirkland and Ellis committing $500 million over the next 3-4 years to build its own proprietary AI platform and custom tools
=====
On this one, I think its the right way forward. If all Magic Circle / Silver Circle law firms are using the same AI tools to help drafting contracts (Harvey / Legora), and review them too, as well as providing advice, all solutions will become kind of standard, so ultimately the difference between law firms will be reduce only to 1) pricing and 2) charisma of each particular lawyer (e.g., building the relation with the client). this 2nd point cannot be replaced by AI, so probably most of the efforts need to shit into building more and better relations of trust.
