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.
6 min
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.
7 min
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.
8 min
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.
8 min
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.
7 min
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.
7 min
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.
8 min
Moonshot AI drops Kimi K3 — a 2.8-trillion-parameter open MoE with 1M context and weights coming July 27 — hours before Gemini 3.5 Pro misses its launch window. Plus Claude Code 2.1.212's runaway-agent caps and NVIDIA's open Nemotron 3 Embed models, with plain-language lessons on why agent loops need budgets and what embeddings actually are. Hosts: Alex & Jules. New episodes daily.
9 min
Claude Code 2.1.211 ships subagent text streaming and a quietly huge performance fix — up to 7x faster tool rounds when you run lots of MCP tools. Then the big one: the next Model Context Protocol spec (final July 28) drops sessions entirely and goes stateless, so remote MCP servers scale like any boring web API. We teach stateful-vs-stateless and why loading too many MCP tools silently taxes your agent, plus open-weight news (Inkling, GLM-5.2, MiniMax M3). Hosts: Alex & Jules. New episodes daily.
8 min
Claude Code v2.1.210 is a security-first release: the agent is hardened against indirect prompt injection, a sub-agent worktree-isolation hole is patched, and the permission classifier now defaults to Sonnet 5. We teach what indirect prompt injection actually is and why privilege separation shrinks the blast radius — plus a look at Grok Build's agent ergonomics polish. Hosts: Alex & Jules. New episodes daily.
8 min
Claude Code's desktop app adds a built-in sandboxed browser — and ships the safety rails in the same release. Plus Cursor 3.11 (side chats + an iPhone app), Cognition's SWE-1.7 at 1,000 tokens/sec, Grok 4.5's self-disclosed benchmark contamination, and free-tier background agents in the Gemini API. We break down what "sandboxed" actually protects and why you should distrust a leaderboard number. Hosts: Alex & Jules. New episodes daily.
8 min
Claude Code adds a fallbackModel setting that keeps long sessions alive when your primary model is overloaded, X launches hosted MCP servers for Cursor and Claude, and AgentPrizm ships a governed persistent-memory layer for agents. We teach why models get "overloaded," the difference between local and hosted MCP servers, and why language models forget everything between sessions. Hosts: Alex & Jules. New episodes daily.
8 min
Claude Code 2.1.207 makes agent auto mode the default on enterprise backends and squashes the terminal-freeze bug, Cursor 3.11 adds side chats to keep your main agent focused, and Windsurf lets subagents call MCP tools directly. Plus a leaderboard check on open weights — and a plain-English breakdown of Mixture-of-Experts and why "active parameters" is the number that actually predicts your cost. Hosts: Alex & Jules. New episodes daily.
7 min
Claude Code 2.1.206's /doctor now offers to TRIM your CLAUDE.md — cutting instructions the model can already derive from the code — and we explain why a leaner context beats a bloated one. Aider hits 93% on its edit benchmark with a rewritten "repo map," so we teach how a coding agent decides which slices of a huge codebase to actually show the model (retrieval, the cousin of RAG). Plus OpenCode passes 165K stars and rebrands to Anomaly, and Windsurf's Devin Local adds ACU usage display and faster MCP startup. Hosts: Alex & Jules. New episodes daily.
8 min
GPT-5.6 launches publicly today as three tiers — Sol, Terra, and Luna — across ChatGPT, Codex, and the API. We break down Kimi K2.7 Code landing in GitHub Copilot on a US host and use its pricing to teach prompt caching, then cover MCP's biggest-ever rewrite going stateless (and what stateful vs stateless actually means for your infra costs). Plus a Claude Code headless fix and why model routing is now the default. Hosts: Alex & Jules. New episodes daily.
8 min
Mistral 3 ships open-weight — small dense models plus a "fat but sparse" 675B mixture-of-experts — so we finally explain what MoE actually means and why active-vs-total parameters is the whole story. Plus Microsoft wires Dataverse into Claude, Cursor, and Copilot over MCP with real governance (the defense against yesterday's agentjacking), and Claude Code's background agents now open their own draft pull requests from isolated worktrees. Hosts: Alex & Jules. New episodes daily.
7 min
We break down "agentjacking" — a new attack where a fake Sentry bug report tricks Claude Code or Cursor into running malicious commands via MCP — and teach the prompt-injection flaw behind it: why a model reads instructions and data in the same breath. Plus the Fable 5 inclusion window closing today, and GitHub Copilot's CLI going model-agnostic with Kimi K2.7 alongside Claude. Hosts: Alex & Jules. New episodes daily.
