📆 ThursdAI - Jan 15 - Agent Skills Deep Dive, Claude Cowork for the Masses, GPT 5.2 Codex in the API

Quick Overview

The ThursdAI January 15 episode provided a deep dive into Anthropic's Agent Skills, celebrated the release of Claude Co-work for non-coders, confirmed the API release of GPT-5.2 Codex, and covered significant open-source model updates and industry drama, including Apple's partnership with Google Gemini for Siri.

Key Points: Anthropic's Agent Skills, previously requiring a subscription, are now an open standard adopted across multiple tools, and the show promised to detail how to use them without paying Claude. Claude Co-work launched, bringing Claude Code's agentic capabilities to the desktop app for non-coders, which was reportedly written entirely using Claude Code in a week and a half sprint. OpenAI finally released GPT-5.2 Codex via API, priced at $1.75 per million tokens, which agent harnesses like Cursor immediately used, with Cursor creating a whole browser from scratch with over three million lines of code using it. Byron released M3, an open-source 235 billion parameter medical LLM fine-tuned from Qwen 3, claiming it beats GPT-5.2 on healthcare benchmarks with a 65.1 score on Healthbench. Muan released LongCat Flash Thinking 2601, an MIT licensed model with 560B total parameters, achieving 100% of AME25 and outperforming Claude Opus 4.5 thinking on specific tasks. Apple announced that Google's Gemini will power Siri, running on-device and in private cloud compute, leading to speaker frustration that Siri remains 'still so so so stupid' despite the partnership. OpenAI announced a $10 billion partnership with Cerebras for 750 megawatts of compute, inked for 2028, highlighting the race among LLM labs to secure specialized high-speed inference hardware.

Context: The 'ThursdAI' episode for January 15, hosted by Alex Walov with co-hosts Misti and Wolf from Ravenwolf, focused on recent major developments in the AI ecosystem, particularly emphasizing agent capabilities and accessibility for non-developers. Key discussions centered on Anthropic's Agent Skills becoming an open standard, the launch of Claude Co-work, and major model releases from both open-source and large corporate labs, alongside notable industry drama.
