The pace at which LLM's are being refreshed is insane. Week 12 had OpenAI's GPT-5.4-mini, Minimax-2.7 which helped design and optimize its own training and evaluation harnesses. Cursor's Composer-2 which itself was built on top of Kimi-K2.5. Anthropic has also been on a roll with its shipping velocity on Claude Cowork as well as Claude Code. Other interesting things were Fal's release of its MCP server and Packy McCormick's and Pim de Witte's 19K word article on World models. Readers who think others in their family, friends and acquaintances who are curious in knowing more about rapidly evolving AI tools/services/use cases and would benefit from being subscribers of this weekly newsletter are encouraged to share this publication link to them and invite them to subscribe The following messages were posted on the 'All Things AI' Telegram group from Sunday 15th Mar 2026 to Saturday 21st Mar 2026Sunday 15th March 20261via Yat Siu MiroFish: The God View Engine A developer in China built an AI engine that generates thousands of digital humans - each with their own personality, memory, and behavior - drops them into a virtual world, and watches them predict the future.

Maybe future pricing of models will also be time-based Aakash Gupta @aakashgupta This two-week promo tells you more about AI infrastructure economics than any earnings call this quarter. Anthropic hit $19 billion in annualized revenue as of early March. They raised $30 billion at a $380 billion valuation five weeks ago. Claude Code alone crossed $2.5 billion Claude @claudeai A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks. 257 12:05 PM • Mar 15, 2026 Monday 16th March 20261via Robby Yung Christos Tzamos @ChristosTzamos 1/4 LLMs solve research grade math problems but struggle with basic calculations. We bridge this gap by turning them to computers. We built a computer INSIDE a transformer that can run programs for millions of steps in seconds solving even the hardest Sudokus with 100% accuracy 5,939 5:30 AM • Mar 12, 2026 Reply via Alex I dont get this "in model execution" just feels like the wrong direction. Why delegate to a stochastical model what a deterministic algorithm can solve infinitely more efficiently? The author managed to get a model to solve a sudoko in 3 minutes by burning >9m tokens, while it is trivially easy to write an algorithm that brute forces a sudoku in a fraction of a second. lol2Some members of this group may be aware that I curate a Notion page named 'AI/ML Resource Hub' though many a times I've thought of just removing it given how powerful answer engines have become. There is still some opinionated curation which may not resonate with everyone Recently whilst sampling friends/colleagues/acquaintainces on how they were providing context to their coding harness and researching some new tooling, I wrote the following new sub-page and incorporated that into the hub. Feedback greatly appreciatedPublic: Nia versus Context7 | NotionBackground about Nia via this tweet thread which first came to my attention as an alternative to Context7https://yusuf-goolamabbas-53.notion.site3via Tim Happy to share this big x402/agent update courtest the Agent0 SDK team: Tim Cotten @CottenIO This is incredibly important. This is OUR tool for the agent economy. Agent0 SDK was built by members of the same team, like @marco_derossi, who led the ERC-8004 standard working group. As of this morning it brings native support for x402 payments into the same package that agent0 Lab @agent0lab Your agent just got an identity, a voice, and a wallet in one SDK. 8004 for identity.

Data (Proprietary and inaccessible) 2. Workflow (Deeply embedded operations) 3. Regulatory (Licenses and contracts) 4. Distribution (Exclusive proprietary channels) 5. Ecosystem (Third-party platform reliance) 6. Network (Marketplace liquidity density) 7. Physical (Infrastructure and atoms) 8. Scale (Low cost through volume) 3Minimax-2.7 released The Shanghai-based MiniMax lab released MiniMax-M2.7 via API, excelling on benchmarks like 56.22% on SWE-Pro for software engineering and leading open-source models at 1,495 ELO on GDPval-AA. It handles a 204,800-token context, outputs at 60-100 tokens per second, and starts at $0.3 per million input tokens, making advanced agent tasks accessible.MiniMax M2.7: Early Echoes of Self-EvolutionIn the months following the first release of our M2-series models, we received a large volume of feedback and suggestions from enthusiastic users and developers, which drove us to further accelerate the efficiency of our model iterations. With human productivity already fully unleashed, the natural next step was to initiate self-evolution of both the model and the organization.https://www.minimax.io4Anthropic rolled out Dispatch in its Claude Cowork desktop app, letting users pair their phone with a persistent AI session on their computer to handle jobs like file analysis or Slack searches while away. It starts as a research preview for Max subscribers, with Pro access coming soon, and runs securely in a sandbox after user approval. The feature rivals open-source tools like OpenClaw by offering easy, local automation without maintenance hassles or security risks, as noted by users like Ethan Mollick who say it covers most of what they needed. Felix Rieseberg @felixrieseberg We're shipping a new feature in Claude Cowork as a research preview that I'm excited about: Dispatch!

The company prohibits routing consumer subscriptions like Claude Max—priced around $200 monthly—through third-party apps, enforcing this since January 2026 with errors and suspensions. Users can still access Claude models via official API keys or platforms like Amazon Bedrock, while OpenCode supports over 75 providers including OpenAI and Google Gemini. dax @thdxr opencode 1.3.0 will no longer autoload the claude max plugin we did our best to convince anthropic to support developer choice but they sent lawyers it's your right to access services however you wish but it is also their right to block whoever they want we can't maintain an 8,354 4:33 AM • Mar 20, 2026 Saturday 21st March 20261via Robby Yung 𝙋𝙖𝙨𝙨𝙡𝙪𝙤 @passluo Ladies and 乡亲们, Let's welcome the world's first Claw running on Nintendo Switch The Childless Cat Lady Tutorial will arrive tomorrow 139 10:29 PM • Mar 20, 2026 2In a Claude blog post, Anthropic product leader Cat Wu details four key changes for PMs facing fast-evolving AI: short 'side quest' sprints, demos over documents, revisiting features after each model update, and embracing simplicity to avoid failures. Her Claude Code team turned quick prototypes—like desktop support and todo lists—into launches after positive internal feedback, while evals now measure model performance. External PMs from Google, Microsoft, and others echo the gains, noting specs are evolving into the product itself as roles blur in collaborative workflows. cat @_catwu The PM playbook was built on an assumption that the technology underneath your product is roughly stable With the current pace of model progress, this is no longer true. Here's how we've evolved the PM role: 1,037 5:21 AM • Mar 21, 2026 Shubham Saboo @Saboo_Shubham_ Loved this. Wrote about the changing PM skillset a few months ago before I started running my OpenClaw Agent team. Since then it moved from building with agents to managing agents with personalities and roles.
