* @steipete on Anthropic: "Anthropic is officially killing third-party harnesses that let power users get API-like performance for $20/month. If you're running heavy automation, it's time to pay the piper." x.com/steipete/status/2040209434019082522(https...)
* Ronan Farrow's New Yorker investigation into Sam Altman is the deepest look yet at OpenAI's internal power structure — and it's a lot. newyorker.com/magazine/2026/04/13/sam-altman-ma...)
* @karpathy on OpenAI's industrial policy: "They're floating government wealth funds and 4-day workweeks. Either they're genuinely prepping for the AGI economy or they're playing 4D chess with regulators."
* Google DeepMind found that AI agents can be quietly hijacked through hidden patterns embedded in normal web content — stuff human eyes would never catch. x.com/kimmonismus/status/2041109663278637145(ht...)
* Neuromorphic AI breakthrough: 100x energy efficiency gains while keeping 98% accuracy, by firing only during "spiking" events instead of hammering a GPU constantly. reddit.com/r/singularity/comments/1sdxdn6/ai_br...)
* @theo on Claude Code: "After months of use, the biggest time sink is dealing with 'silent fake success' — the agent says it's done, but the code is actually broken." x.com/theo/status/2040988058427023668(https://x...)

Best to Build With Today
* Coding — gpt-5.4-xhigh leads for agentic multi-step tasks; gpt-5.2-codex for pure code.
* Reasoning — claude-opus-4-6-thinking-auto is the top choice for complex logic.
* Chat — gemini-3.1-pro is the overall current leader in Chatbot Arena.
* Open-source — Gemma 4 (26B/31B) is the new king of local execution on consumer hardware.
* Value pick — gemini-2.5-flash-preview gives you massive bang for your buck on reasoning tasks.

💼 Industry & Business
Anthropic restricts third-party harnesses
Anthropic is now blocking automated wrappers and scrapers from piggybacking on Claude Pro subscriptions. If you've been relying on those tools, it's time to move to API billing. They're clearly cracking down on "token arbitrage" — the trick where power users squeeze enterprise-level compute out of a $20/month plan.

The New Yorker investigation into Sam Altman
Ronan Farrow spent 18 months digging into OpenAI's power structure, and the result is a must-read. Using internal documents, it circles back to the question everyone's been dancing around: can a company this centralized actually govern itself safely?
� Twitter� Reddit
OpenAI's Industrial Policy proposal
OpenAI dropped a policy blueprint floating ideas like government wealth funds and 4-day workweeks to cushion the economic blow of AGI. Translation: they're writing the rulebook before regulators get a chance to write it for them.

Bernie Sanders on AI 'oligarchs'
Sanders is done pulling punches — he's calling for democratic oversight to make sure AI doesn't just make a handful of billionaires richer. The conversation has officially left tech Twitter and landed in mainstream politics.

🧠 Models & Research
DeepMind's 'Systemic Hidden Manipulation'
DeepMind found that AI agents can be steered by invisible patterns baked into websites or images. These nudges slip right past current safety filters, meaning an agent could be quietly manipulated without any visible red flags.

100x Energy Efficiency Breakthrough
A new neuromorphic architecture mimics the brain by only kicking into gear during "spiking" events — no constant processing. If this scales, it could actually solve AI's most stubborn problem: the eye-watering cost of compute.

🚀 Products & Launches
Claude Code reliability issues
Developers are fed up with "silent fake success" — the agent confidently reports a task is done while the code underneath is quietly broken. It's a useful reality check on just how far coding agents still need to go before anyone calls them production-ready.

Hermes Agent ecosystem update
Hermes Agent just got a solid upgrade: MCP server support and a 2M character context window. It's shaping up to be a genuine open-source option for anyone running serious local agentic workflows.

Funding & Deals
* Anthropic acquired Coefficient Bio for $400 million to push harder into AI-driven drug discovery and protein engineering.
* Obsidian hit a $350 million valuation with just 9 employees and zero VC funding — proof that you don't need a war chest to build something people love.
Launches
* Gemma 4 — Google's new open-weights model family (up to 31B) is out and already making noise on local benchmarks, including on M3 Pro chips.
* Apple Nvidia eGPU Driver — Official support for Nvidia external GPUs on Arm Macs is finally here, which means local CUDA compute is now actually on the table for Apple users.
Closing thought: Between DeepMind's manipulation findings, Sanders pushing AI regulation into the mainstream, and Anthropic locking down cheap API access, the "wild west" phase of AI is clearly wrapping up. We're moving into a new era — one defined by tighter controls, real costs, and actual political consequences.
