JSON Tool Calling Is Dead. Here’s What Replaces It

JSON Tool Calling Is Dead. Here’s What Replaces It

⋅

Author(s): MKWriteshere Originally published on Towards AI. Anthropic just made code-based tool orchestration the default path forward. Hugging Face saw this coming in December 2024. Here’s a pattern you’ll notice if you watch the AI industry closely enough: the open-source community figures something out, publishes it quietly, and then a major lab ships it eight weeks later with a press release.

The Data Stack’s Next Form Factor: Multi-Agent Systems

⋅

Traditional data platforms rely on centralized monoliths and complex engineering pipelines that often create bottlenecks for business decision-makers. This article introduces Da2a, an open-source prototype that proposes a decentralized, agentic architecture where specialized Domain Agents (e.g., Marketing, E-commerce) collaborate through a Root Orchestrator using the Agent-to-Agent (A2A) protocol. By treating data sources as autonomous experts that communicate via standardized “agent cards” rather than static tables, Da2a demonstrates how multi-agent systems can intuitively solve complex cross-domain problems, offering a […]

Andrej Karpathy talks about “Claws”

Andrej Karpathy talks about “Claws” Andrej Karpathy tweeted a mini-essay about buying a Mac Mini (“The apple store person told me they are selling like hotcakes and everyone is confused”) to tinker with Claws: I’m definitely a bit sus’d to run OpenClaw specifically […] But I do love the concept and I think that just like LLM agents were a new layer on top of LLMs, Claws are now a new layer on top of LLM agents, taking […]

After fueling test, optimism grows for March launch of Artemis II to the Moon

After fueling test, optimism grows for March launch of Artemis II to the Moon

⋅

A second fueling test on NASA’s Space Launch System rocket ended Thursday night, giving senior managers enough confidence to move forward with plans to launch four astronauts around the Moon as soon as March 6. Unlike the first attempt to load propellants into the SLS rocket on February 2, there were no major leaks during Thursday’s practice countdown at Kennedy Space Center in Florida. Technicians swapped seals at the launch pad after hydrogen gas leaked from the rocket’s […]

Toward AI Autonomous Navigation for Mechanical Thrombectomy using Hierarchical Modular Multi-agent Reinforcement Learning (HM-MARL)

⋅

Mechanical thrombectomy (MT) is typically the optimal treatment for acute ischemic stroke involving large vessel occlusions, but access is limited due to geographic and logistical barriers. Reinforcement learning (RL) shows promise in autonomous endovascular navigation, but generalization across ‘long’ navigation tasks remains challenging. We propose a Hierarchical Modular Multi-Agent Reinforcement Learning (HM-MARL) framework for autonomous two-device navigation in vitro, enabling efficient and generalizable navigation. HM-MARL was developed to autonomously navigate a guide catheter and guidewire from the femoral […]

Intuitive Intro to Reinforcement Learning for LLMs

⋅

RL/ML papers love equations before intuition. This post attempts to flip it: each idea appears only when the previous approach breaks, and every concept shows up exactly when it’s needed to fix what just broke. Reinforcement Learning for LLMs “made easy” submitted by /u/zephyr770 [link] [comments]

Adding TILs, releases, museums, tools and research to my blog

⋅

I’ve been wanting to add indications of my various other online activities to my blog for a while now. I just turned on a new feature I’m calling “beats” (after story beats, naming this was hard!) which adds five new types of content to my site, all corresponding to activity elsewhere. Here’s what beats look like: Those three are from the 30th December 2025 archive page. Beats are little inline links with badges that fit into different content […]

MAHA moms threaten to turn this car around as RFK Jr. flips on pesticide

⋅

Members of the Make America Health Again movement are in open revolt after founder Robert F. Kennedy Jr. publicly backed President Trump’s executive order Wednesday that would increase domestic production of glyphosate—a pesticide the MAHA movement and Kennedy have railed against. Vani Hari, an ally of Kennedy who goes by “Food Babe,” told The Washington Post she was left “speechless” by the move. “We truly were hoping that this administration would put people over corporate power,” she said, […]

Building a Simple SQL Query Generator Using LLMs

Building a Simple SQL Query Generator Using LLMs

⋅

Use LLMs to bridge the gap between human language and database queries with Python. Writing SQL is an art, but not everyone enjoys the canvas. For many, the syntax of a complex JOIN or a nested subquery is a barrier to getting the data they need. In our fast-paced world, not everyone has the time to become a database administrator—and with the power of Large Language Models (LLMs), you don’t have to. Instead of teaching you how to write queries, […]
