FROM THE EDITOR
Hi everyone,
We're back to lots of new model launches - OpenAI, Anthropic, Meta, Google, even Thomson Reuters. The new trend seems to be running long, multi-step tasks and lower costs.
Happy learning,
Jenny
TOOLS & LAUNCHES
X · OpenAI · 3 min · 121M views
OpenAI launched GPT-6 Astra, claiming the system can perform any task you can do on a computer — and do it quickly.
WHY THIS MATTERS
If OpenAI’s Astra works as expected, you can point at your screen and say “do it,” instead of writing prompts and clicking.
TOOLS & LAUNCHES
X · Claude · 1 min · 20M views
Claude announced two AI models, Fable 5.1 and Mythos 5.1, pitching them as the world’s most advanced options for coding and knowledge work.
WHY THIS MATTERS
Anthropic says Fable 5.1 costs up to 45% less for long, multi-step jobs — the same work you already run, at a lower bill.
TOOLS & LAUNCHES
X · World Labs · 2 min · 10M views
World Labs unveiled Atlas, which it calls the first AI system that creates images and video frames with precise camera control and rebuilds scenes in 3D, letting users model a scene, move the camera, and simulate space and time.
WHY THIS MATTERS
World Labs’ Atlas lets you lay out shots with real camera moves from one description, instead of hand-building 3D scenes. Check out what people have created online!
TOOLS & LAUNCHES
X · Google · 3.5M views
Google announced Gemini 3.8, calling it its best model for reasoning and coding, three weeks after 3.7 Flash, and introduced two variants: 3.8 Flash and 3.8 Flash Cyber. It uses long-running agent loops, letting the system take successive steps.
WHY THIS MATTERS
This hopefully means less babysitting: Gemini 3.8 can run multi-step tasks end-to-end, so you prompt once instead of shepherding every step.
TOOLS & LAUNCHES
X · AI at Meta · 337K views
Meta released Muse Spark 1.3, which handles multi-step tasks and coding better, keeps several tasks going, asks clarifying questions, flags when stuck, confirms actions, makes up answers less, and needs ~20% fewer tool uses and ~25% less text.
WHY THIS MATTERS
Meta’s Muse Spark 1.3 lets you hand off multi-step workflows for less — 20% fewer tool uses and 25% less text.
BUSINESS
X · NVIDIA Newsroom · 67.9K views
Nvidia agreed to buy Hugging Face and says it will invest in the site’s infrastructure and growth, while keeping it a neutral home for open-source AI tools that work with any cloud or hardware.
WHY THIS MATTERS
Your Hugging Face AI models could get a major speed upgrade soon — with Nvidia’s cash, without locking you to Nvidia hardware.
BUILDERS
X · ClaudeDevs · 1 min · 2M views
Anthropic’s ClaudeDevs open-sourced Claude Commerce Agents, a blueprint and sample apps for building shopping and merchant assistants that handle tasks end to end, with working examples for retail, travel, telecom, and entertainment.
WHY THIS MATTERS
This is huge news for retail, travel, and telecom. They claim that retailers running shopping agents on Claude have already seen carts up to 35% larger and shoppers 60% more likely to complete a purchase.
RESEARCH & THOUGHT
X · Stephanie Palazzolo · 1.9M views
OpenAI’s Astra uses a “recurrent depth” reasoning method — letting the model loop through its own steps multiple times — which can boost performance and lower cost, but researchers warn it hides how the model reasons, complicating oversight.
WHY THIS MATTERS
You’ll get cheaper, better answers from OpenAI’s Astra, but you lose a clear trail to check how it decided.
TOOLS & LAUNCHES
X · Zach Moskow · 660K views
Thomson Reuters launched a large language model called Thomson, trained continually on 175 years of its proprietary legal, tax, accounting, and news data, and says it spent $40 million building it.
WHY THIS MATTERS
Great example of moat using proprietary data. This Thomson Reuters model gets legal and tax answers from 175 years of archives, not generic web guesses.
BUSINESS
Web · Tyler Cowen · 14 min
U.S. Census surveys show AI adoption rose from 3.7% (2023) to ~10% by late 2025 (18% with a broader question), yet about 96% of firms report no employment change; AI mostly augments tasks like writing, search, and summarization.
WHY THIS MATTERS
AI is powerful but has not transformed companies and jobs yet. Most organizations seem to be using it as a productivity booster.
