Day 45 · May 3, 2026The Agentic AI Voice StackVoice has quietly become the highest-stakes surface in the agentic AI stack. Not because it's new -- but because in 2026 the latency, naturalness, and tool-action fidelity finally cleared the bar where users stop…
Day 44 · May 2, 2026Why Run Agents on the Edge at All?Cloud agents have four taxes: latency (round-trip even on 5G is 80-250ms before the model thinks), cost (frontier inference at scale), privacy (every memory read leaves the device), and availability (no signal, no…
Day 43 · May 1, 2026The New Competitive Moat for Agentic AIAs AI agents become production reality, prompt engineering alone is no longer enough.
Day 42 · April 30, 2026AI Agents & The New Developer Stack — How Coding Is Being ReinventedAfter 37 days of learning how agentic AI works, today we zoom in on what it means for software developers.
Day 41 · April 29, 2026Which Roles Are Exploding in Demand -- and How to Position YourselfDomain expertise + AI fluency > pure AI skills. A finance expert who can deploy LangGraph agents for regulatory reporting is worth more than a generic LLM engineer.
Day 40 · April 28, 2026The Agent Economy Meets Climate & Energyunprecedented rate. Training Grok 4 alone emitted ~72,000 tons of COn, equivalent to driving 17,000 cars for a year.
Day 39 · April 27, 2026Agentic AI Crosses Into Hospital Wards, Pharma Pipelines, and Clinical WorkflowsFrom AI agents that cut prior authorisation from 45 minutes to under a minute, to the first fully AI-designed drug now in Phase IIa trials, to cancer-metastasis prediction at 80% accuracy -- today you learn how the…

Takeaways of the week

Pick cascade for control, S2S for naturalness Default to cascade (STT → LLM → ElevenLabs Flash v2.5) for any agent that needs MCP tool calls, evals, or per-component swap. Reach for Sesame CSM / OpenAI Realtime when conversational warmth is the moat (companion apps, sales, healthcare intake). Day 45
Budget every component for <600ms TTFT STT <150ms streaming, turn detection <80ms, LLM <250ms (use DeepSeek V4 Flash $0.14/M for routing, frontier only when needed), TTS first-byte <100ms. Anything above 600ms total and users disengage. Day 45
Tomorrow (Day 41) -- Agentic AI Voice Stack Speech is the mo Tomorrow (Day 41) -- Agentic AI Voice Stack Speech is the most natural agent UI. We'll cover: ElevenLabs MCP, OpenAI Realtime API, Whisper-Tiny on-device, Voice Mode 2.0 (TTFT <600ms), interrupt-handling, and the avatar+voice fusion that HeyGen Avatar V kicked off. Plus how to keep voice agents under EU AI Act Article 50 and biometric-data rules. artificialintelligenceact.eu, TheNextWeb (OpenAI×Qualcomm phone), 24/7 Wall St., FrontierNews.ai (Apple M5), InfoWorld Edge AI, Day 44

Write specs first Before prompting any coding agent, write a one-page spec: goal, constraints, acceptance criteria. This alone will cut your review overhead and make AI output reviewable at a glance. Day 42
Adopt the Three-Agent Harness For any task longer than a single context window: Planner decomposes → Generator builds → Evaluator scores. Use Claude Code's coordinator mode (Epitaxy) to wire this up in minutes. Day 42
as core infrastructure, not an experiment. The AI drug disco as core infrastructure, not an experiment. The AI drug discovery market alone is projected at $4B+ by 2028. Healthcare AI overall: $45B (2026) fi $188B by 2030 at 42.5% CAGR. The governance gap is the biggest moat -- companies that get HIPAA + EU AI Act + NIST compliance right first will lock up enterprise health Day 39
carbon accounting, energy grid optimisation, climate modelli carbon accounting, energy grid optimisation, climate modelling, and the environmental cost of inference itself (Grok 4's training = 72,000 tons COn). Plus: the EU's proposed AI Energy Disclosure requirement coming with the AI Act Day 39
