AI Tools Daily

Claude Code makes Sonnet 5 its default model with a native 1M-token context window, and China's GLM-5.2 takes the #1 open-weight spot — the perfect excuse to explain mixture-of-experts, why a 744B-param model only fires 40B at a time. Plus Claude Code's new Manual permission default, Claude in Chrome going GA, and Cursor's auto PR-review pass. Hosts: Alex & Jules. New episodes daily.

Anthropic quietly pulled hidden China-tracking code out of Claude Code after a Reddit user reverse-engineered it, and Alibaba responded by banning the tool for its employees. We also cover Claude Fable 5's return after an 18-day export-control freeze, a new default that flips Claude Code to "Manual" permission mode, and Cursor's iOS launch with a discount ending tomorrow. Today's concept: what an agent's permission loop actually does. Hosts: Alex & Jules. New episodes daily.

Windsurf's Cascade agent hit end-of-life and got replaced by Devin Local — here's what to repoint in your CI. Claude Code's new default ships a native 1M-token context window, which gives us a chance to break down what a context window actually is and why bigger isn't free. Plus Codex retires two models and DeepMind's AlphaEvolve keeps landing in unexpected places. Hosts: Alex & Jules. New episodes daily.

Anthropic's Fable 5 is restored globally after a three-week US export control triggered by a jailbreak that let the model produce working exploit code — we break down what a jailbreak actually is and why this model's guardrail story matters to every developer. Plus: Cloudflare sets a September 15 deadline that could break web-browsing agents, Cursor reveals its enterprise "software factory" playbook, and OpenAI's open-weight models land in AWS GovCloud. Hosts: Alex & Jules. New episodes daily.

Claude Sonnet 5 is now the default model in Claude Code — and it ships with a native one-million-token context window. We explain what a context window actually is, why a million tokens is a genuine game-changer for developers working on large codebases, and where the tradeoffs still lurk. Plus: Claude Code 2.1.196 lands with background agent reliability overhaul and a supply-chain security fix for MCP in multi-repo setups. And if you're on Devin Desktop (formerly Windsurf), the Cascade local agent hit end-of-life today — here's what to do. Hosts: Alex & Jules. New episodes daily.

Claude Code v2.1.195 landed a critical hook matcher fix — if you use MCP servers with hyphens in their names, your hooks may have been silently misfiring, and we explain exactly what to change. Then: ByteDance dropped Seed 2.1 Pro and Turbo, claiming Opus-class agentic coding at 80% lower cost — and why that pricing pressure matters even if you never touch their API. We also break down what Claude Code hooks actually are, how glob pattern matching works, and why exact-match versus substring-match is the kind of distinction that quietly breaks your security tooling. Hosts: Alex & Jules. New episodes daily.

Anthropic's Claude Security hits public beta, scanning whole codebases by reasoning about data flows instead of pattern-matching — we explain how that differs from a traditional scanner. Plus Cognition's FrontierCode benchmark, where the best model scores just 13% on whether its pull requests are actually mergeable, and Claude Code's latest releases add shell MCP login and fix silent subagent permission denials. Along the way we teach how AI vulnerability scanning works and why "mergeability" is a harder bar than "correctness." Hosts: Alex & Jules. New episodes daily.

A solo researcher mapped ten thousand malicious GitHub repositories actively targeting AI agent developers with credential-stealing malware — and we break down what to check. Cactus Compute distilled Gemini's tool-calling skill into a 26-million-parameter, 14MB model that runs entirely on-device, and we explain how model distillation works so you understand *why* that's possible. Plus, OpenCode — the open-source, model-agnostic terminal coding agent — just hit #1 in the rankings with 160K GitHub stars and 7.5M monthly active developers. Hosts: Alex & Jules. New episodes daily.

GitHub Copilot now lets JetBrains users switch to Claude as their coding agent with a two-step setup. Claude Code hits GA on Dynamic Workflows and ships a new sandbox credential-blocking setting. MiniMax M3, an open-weight model beating GPT-5.5 on coding benchmarks, gets unpacked — including the Mixture of Experts architecture that makes a 1M-token context window computationally feasible. Plus: OpenAI acquires Gitpod to give Codex persistent cloud memory. Today's teaching concept: Mixture of Experts (MoE) — why activating only 23B of 428B parameters is the key to M3's speed and scale. Hosts: Alex & Jules. New episodes daily.

Cursor shipped three major updates in one week — cloud subagents, Slack-triggered automations, and a unified Customize page — and Alex breaks down the shift to push-mode, event-driven agents that react to GitHub and Slack instead of waiting to be chatted with. Plus: Claude Fable 5 is back from its export ban with new restrictions and a silent-refusal API change (HTTP 200, not an error) that could be silently breaking your integration right now. And Gemini CLI is officially dead — if it's in your workflow, it stopped working June 18. Hosts: Alex & Jules. New episodes daily.
