A Guide to Which AI to Use in the Agentic Era

One Useful Thing • 4712 implied HN points • 18 Feb 26
đź•ą Technology Productivity Tools
  1. Decide between three layers: models (the AI brain), apps (the interface you use), and harnesses (the systems that let the AI use tools and act autonomously).
  2. If you want real work done, pay for and select advanced models or "thinking/Pro" modes, because free/default chat models are optimized for casual talk and make more errors.
  3. The big shift is from chatbots to agentic harnesses that can complete multi-step tasks; harness choice now often matters more than model choice, so try agent tools (like code or document-focused harnesses) and manage the AI as it works.

The Algorithmic Bridge • 1815 implied HN points • 07 Feb 26
đź•ą Technology Productivity Tools
  1. AI is making the 'how' of work much cheaper, so the real bottleneck is deciding what to do and what you actually want to achieve.
  2. Human skills that matter now are different: taste, judgment, initiative, decision‑making, curiosity, and the ability to manage agents — and each is a distinct skill to practice.
  3. Many people will resist because execution feels devalued, so you need to update your self‑image, embrace curiosity, and learn to ask better 'wishes' if you want to get the most from these tools.

Using GPT LLM MAMLMs as Your Rabbit—Your Pacer

Brad DeLong's Grasping Reality • 261 implied HN points • 22 Nov 25
đź•ą Technology Productivity Tools
  1. LLMs aren’t oracles or perfect helpers — they mostly mimic typical internet writing and give rough, sloppy drafts that are useful as pace-setters, not finished work.
  2. All the tricks to make them better (context engineering, fine-tuning, RAG, etc.) are heavy, fragile, and costly patches. Only invest in that work when you really need high-volume or specialized, production-ready output.
  3. AI can lift weak writers and handle boilerplate well, but for persuasive or high-quality writing the best workflow is to use the model for a rough draft and then heavily rewrite it into something authentic.

The hidden costs of pre-computing data | Chalk's Elliot Marx

Dev Interrupted • 14 implied HN points • 09 Dec 25
đź•ą Technology Productivity Tools
  1. Pre-computing and storing large volumes of derived data wastes money and adds latency because most of it is never used. Shifting to real-time, incremental pipelines means you only compute what users actually need.
  2. Owning the full stack (hardware, training, and cloud) creates a competitive moat and can change leaderboard dynamics quickly. Design your systems to be model-agnostic and flexible so you don’t get locked into one provider.
  3. Typical engineering metrics like velocity or lines of code are often misleading; measure what exposes real friction, bottlenecks, and business outcomes. Use metrics to make the system legible and actionable, not just to produce executive reports.
