Stop using OpenCode like a Claude Code clone
The OpenCode config that earns its keep — opencode.json layers, the build/plan agents, permissions, AGENTS.md, MCP, and the bring-your-own-model setup that survives a vendor pulling your access.

Loop engineering and the terminology treadmill: what 47 Claude Code runs actually show
On June 7, 2026, X renamed the agent loop 'loop engineering' and called it the successor to harness engineering. We ran 47 Claude Code loops in a sandbox to test the claims. The naming churns; three of the technical findings are real and one is measurable to the cent.

Agents run Main Street: a16z's SMB bet and the vertical wedge underneath
In one week in June 2026, a16z published a manifesto declaring small businesses 'the next frontier for AI' and led three rounds for companies promising to run the business itself. The pitch is horizontal. Every winner is vertical.

Lockdown Mode is OpenAI admitting prompt injection is unsolved
On June 6, 2026, OpenAI shipped a security feature that works by turning agents off. The same week, Grok started filling grocery carts and Qwen started driving desktops. Read together, the frontier just conceded the action layer is the unfixable attack surface.

Anthropic's S-1 and OpenAI's Foundation: two trillion-dollar bets, one week
On June 1, 2026, Anthropic filed confidentially to go public at a $965B valuation while OpenAI's nonprofit Foundation published its case for spending $25B on 'AI resilience.' Two leading labs, same day, opposite bets: one privatizes the upside, the other pre-commits capital to the downside.

The open-weight coding frontier caught Claude, and it speaks Mandarin
In a three-week window, MiniMax M3, Qwen3.7-Max, DeepSeek V4, Kimi K2.6 and Nemotron 3 Ultra all claimed the frontier. The third-party leaderboards say the gap is real and small. The marquee numbers are mostly the labs grading their own homework. And the open-weight crown carries a jurisdiction risk no benchmark measures.

The agent-governance land-grab: who's buying the control plane
In six weeks, Palo Alto bought Portkey, Cisco bought Astrix, Asana bought StackAI, and $340M flowed into agent-identity startups. The fifth wheel nobody shipped in open source is being bought, not built. A map of the five control-plane layers and the buyers racing to own each one.

The agent-framework field reinvents the same five wheels
Eleven OSS agent runtimes, one recurring pattern: memory, sandboxing, skills-vs-MCP, tool governance, and transport. Only Letta solved memory, only smolagents solved sandboxing, and the 2026 vendor SDKs are quietly absorbing the rest into hosting platforms.

Grok Build, and the model xAI didn't make
xAI shipped a terminal coding agent, then put a competitor's model inside it that out-codes its own. Read against a $60B SpaceX option on Cursor, the CLI war looks less like four rivals and more like one stack assembling itself.

The agent-sandbox wars: 23 companies and a contested substrate
Modal raised $355M at $4.65B selling AI agents a computer. So are 22 other companies. A map of the sandbox infrastructure race — who runs Firecracker, who doesn't, and why the substrate war is nearly settled while everything above it is wide open.
