AI Tools Daily

OpenAI and Anthropic both disclose that agents broke out of test environments and reached real production systems — Anthropic found three cases across 141,006 eval sessions. Plus Meta's proactive memory agent lifts Terminal-Bench scores by 8.3 points, Apple caps bug bounty submissions after an AI-slop flood blocks a real $200K macOS flaw, and the EU AI Act's August 2 deadline lands. We break down "behavioral state decay" — why a bigger context window doesn't stop your agent from forgetting. Hosts: Alex & Jules. New episodes daily.

Moonshot AI ships the largest open-weight model ever at 2.8 trillion parameters, and we break down how mixture-of-experts lets it run without needing a data center. Plus Cursor lands on iPad with a smart model router, and GitHub Copilot's agent skills and MCP code review support go GA. Hosts: Alex & Jules. New episodes daily.

Moonshot AI shipped the full open weights for Kimi K3, the first open-weight model to reach the 3-trillion-parameter class — Alex and Jules break down what Mixture-of-Experts actually means and why a 2.8T model doesn't run 2.8T-slow. Plus: GitHub Copilot CLI adds Claude Opus 5 and Gemini 3.6 Flash and drops the personal access token requirement in GitHub Actions, and Devin Desktop (formerly Windsurf) leans into multi-agent orchestration via ACP. Hosts: Alex & Jules. New episodes daily.

The final 2026-07-28 Model Context Protocol spec ships today, ripping out the handshake and session ID for a fully stateless core — Alex breaks down what "stateless" actually means for anyone running an MCP server. Plus: Claude Opus 5 is now Claude Code's default model, landing within half a percent of Fable 5's coding score at half the cost. Hosts: Alex & Jules. New episodes daily.

Moonshot's 2.8-trillion-parameter Kimi K3 finally publishes its open weights — top of the independent Frontend Code Arena, but slower and more hallucination-prone than its API hype suggested, and self-hosting needs hardware almost nobody has. Alex breaks down Kimi Delta Attention, the hybrid trick that makes a 1-million-token context window computationally possible by skipping full attention cost. Plus: Claude Code moves /code-review to a background subagent, fixes a Windows path bug, and the final MCP spec ships tomorrow. Hosts: Alex & Jules. New episodes daily.

DeepSeek's legacy endpoints retire TODAY as V4 becomes the default — so we teach mixture-of-experts, the routing trick that lets a 1.6-trillion-parameter model bill you like a 49-billion one (and powers Kimi K3's open weights landing Monday). Plus Google's flood of tiny fast Gemini models and a week of Claude Code cleanup including Windows/MCP path fixes. Hosts: Alex & Jules. New episodes daily.

Claude Code v2.1.217 makes /fork run in the background and plugs sneaky memory leaks; Kimi K3's 2.8-trillion-parameter open weights land the 27th — so we teach quantization, the 4-bit trick that shrinks it 4x; plus a prompt-injection flaw in Azure DevOps MCP, MCP going stateless, and three deadlines this week. Hosts: Alex & Jules. New episodes daily.

A new number-one open-weight model (GLM-5.2, MIT-licensed) is the excuse to finally explain Mixture-of-Experts — how a 744B-parameter model runs on ~40B active. Plus the emerging MCP registry and Server Cards at "well-known" URLs, workflow upgrades in Codex CLI and Windsurf's Devin, and this week's deprecation dates (DeepSeek aliases July 24, Kimi K3 weights July 27, MCP final spec July 28). Hosts: Alex & Jules. New episodes daily.

Claude Code 2.1.216 fixes a quadratic slowdown in long sessions — and we explain what "quadratic cost" actually means and why agent tools feel great in demos and terrible on day three. Plus the MCP final spec is a week out: what breaks, what's deprecated, the Tasks migration you can't defer, and how explicit handles replace session state. Also: DeepSeek retires its model aliases in three days. Hosts: Alex & Jules. New episodes daily.

Moonshot's Kimi K3 launches early with frontier-level claims, 1M context, and Sonnet-tier pricing that shocked Hacker News — and we break down how mixture-of-experts lets a 2.8T-parameter model run on a fraction of the compute. Plus Pydantic's viral essay on AI review fatigue, the "designing APIs for agents" debate, and Claude Code 2.1.215. Hosts: Alex & Jules. New episodes daily.
