Hey —

Three things broke in April that change how we all code: Anthropic shipped Opus 4.7, GitHub froze new Copilot Pro signups, and Cursor 3 turned multi-agent coding from "demo trick" into "default workflow." If you've been ignoring AI tooling news because it all sounds the same, this is the month to look up. The flat-rate subscription era is over — coding tools are now metered compute, and the model under the hood matters more than ever.

This Week in AI Coding

• Claude Opus 4.7 is GA on everything. Anthropic shipped it April 16 across Claude, the API, Bedrock, Vertex, and Foundry — same $5/$25 per-million pricing as 4.6, but a 12-point jump on CursorBench and the first Claude with high-res vision (2576px input). Notable change: it follows instructions more literally and stops "silently generalizing" what you asked for. Worth the migration if you do agentic work.
• The flat-rate party is over. April 20: GitHub paused new signups on Copilot Pro / Pro+ / Student. April 21: Anthropic pulled Claude Code from the $20 Pro plan. Anthropic also chopped the server-side prompt cache from 1 hour to 5 minutes, and Cursor moved frontier models behind Max Mode for legacy plans. Translation: agentic tools are compute products, and compute products always meter.
• Cursor 3 ships an Agents Window. Run multiple AI agents in parallel — local, worktree, SSH, or cloud — from one window. This is the version of "agentic coding" that actually matches the marketing.
• OpenAI's Agents SDK got serious. April 15 update: model-native harness, configurable memory, sandbox-aware orchestration, Codex-like filesystem tools. Built-in support for E2B, Modal, Vercel, Daytona, Cloudflare. This is the moment "agent SDK" stopped being a wrapper and became infrastructure.
• MCP crossed 97M installs in March. It's now foundational infrastructure for agentic coding, not a curiosity. If you haven't built an MCP server yet, you're missing the easiest leverage point in the stack.
• Salesforce shipped Headless 360. Every Salesforce capability as an API, MCP tool, or CLI command — 100+ new tools immediately. The enterprise vendors are catching the MCP wave faster than expected.
• Anthropic's Mythos exists, and you can't have it. Anthropic confirmed it built a model called Mythos that's significantly better than anything public, then locked it behind a 50-company "Project Glasswing" firewall. OpenAI countered with GPT-5.5-Cyber for cyber defenders. Frontier capability is consolidating into curated access — worth watching if you build in regulated spaces.

What We Shipped

• Opus 4.7 migration across the whole VeriduxLabs stack — agents, Claude Code workflows, Kynvo render pipeline. The literal-instruction-following change cleaned up a few flaky agents that were inferring requests we didn't make.
• YouTube pipeline cleared its backlog. @endofcoding is back on a daily Sun-Thu cadence, 110+ videos live. The latest covers AI hiring trends, vibe coding for beginners, and the "$0/month AI coding stack" that keeps surprising people. Sub if you haven't.
• JaaS (Johnny-as-a-Service) shipped a 5-agent overhaul. New CAIO, AI/ML Architect, enhanced QA + CFO, plus a heartbeat system and procedural memory. 1,867 lines. Kanban view next.
• LemonSqueezy went live across CyberOS, the Vibe Coding Ebook, and LLMHire. Paddle is officially deprecated. Building takes weeks, switching payment processors takes a single afternoon — funny how that works.

Tool of the Week: Claude Opus 4.7's File-System Memory

The understated win in 4.7 is better file-system memory for agents. If your agent maintains a scratchpad, notes file, or structured memory store across turns, 4.7 is materially better at writing useful notes to itself and using them later. I've been moving long-running agents over this week and the difference shows up in 5+ turn tasks — fewer context-window stalls, fewer "what was I doing?" moments. If you build agents, the upgrade pays for itself within a day.
