AI

The models, agents, and services I actually run, by role.

updated August 27, 2026

These are the models, agents, and services I run, organized by the job each one does. An item is marked as in use only when there is evidence from the last few months.

Models

  • 2024-03the kernel model
    The interactive session that runs everything else. Opus for heavy fan-outs, Sonnet for cheap classifiers, Fable when available. Fable was the first model I would treat as a taste authority.
  • 2026-04every script
    The workhorse under every AI script, routed through one provider. Also the voice mode, which turned language practice into arguing philosophy in French on the elliptical.
  • 2026-08a second mind
    The same problem gets fed to two models and the outputs compared.
  • 2026-04long files only
    It handles anything over a hundred thousand lines in the summary pipeline.

Agents and harnesses

  • 2025-07the nervous system
    One always-on session rooted in my personal system that reaches into every other repo. The best tool I have for thinking in code.
  • Codexusing
    2026-04the writing hand
    Writes the code and bridges the chat subscription into an SDK provider. I flip between it and Claude Code based on which has usage left.
  • Asideusing
    2026-08arms and legs
    The agentic browser. Anything that has to happen on the web goes here. It is code-mode rather than tool-mode: the agent writes programs against a REPL with browser bindings, so twenty actions cost one round-trip. It is also a sensor that reads without raising; it checked a jury-duty page daily and never surfaced the date.
  • 2026-08overflow lane
    They are dispatched off Linear issues when the other two run out of usage.
  • 2026-04the fleet
    Sixteen always-on agents on the Linux box, one per business. Good for asking one body a question; the fleet view is the gap I am building for.
  • Hermes Agentusing
    2026-04evaluating
    A repository defines an agent and the agent lives on its own machine as a persistent process. I run a fleet on it to learn what my own runtime needs to be.
  • piused
    2026-03 – 2026-08was the userland
    Five months as the daily interface. Retired as an interface in August; it survives as the subprocess that runs test fleets.
  • 2026-01the only framework layer
    It solved provider abstraction and did not pretend to solve the rest.

Capture

  • Plaudusing
    2026-04walking dictation
    Replaced typed journals within a month. A model turns six hours of rambling into a transcript with a spine.
  • 2026-02desk dictation
    The walking recorder took over from it in April.
  • Granolausing
    2025-06meeting transcripts
    A hundred and thirty meetings, a search collection of their own. Coding sessions with an agent are meetings too.
  • 2026-06reading to podcast
    I drop in the reading and get a podcast for the gym.

Retrieval and memory

  • Cortexusing
    2026-01own build
    Keyword and vector search over eleven years of journals, chats, and transcripts, reranked. Content production becomes retrieval, not generation.
  • 2026-03the last step of every search
    Benchmarked against the fast model across twenty queries; kept because losing it noticeably degrades search.
  • Zepusing
    2026-03temporal facts
    Facts with a valid-from and a valid-to, distinct from text search.
  • Raycastusing
    2024-08the launcher as interface
    Launching my own AI commands from a keystroke was the first time a desk felt like a cyborg setup, in 2024.

Generation

  • 2024-08my own cloned voice
    Affirmations and concept rehearsal in my own voice. Last used in April 2026; still wired up.
  • 2026-05explainer videos
    Fan out twenty videos, mark the bad ones, and the next batch is better.

Dropped, with the reason

  • LangChain and LangGraphdropped
    2024-04 – 2024-09
    I never found the happy path in it; the concepts kept multiplying faster than my understanding of what I needed.
  • Mastradropped
    2026-01, 2026-08
    I evaluated it twice. It is built for workflows, and I want autonomy.
  • Grok Botdropped
    2026-08
    I used it for four days. It wants a separate agent per thread and connects only through approved plugins, and I wanted the opposite of both.
  • Azure OpenAIdropped
    2026-03 – 2026-08
    The sponsored credits expired. Image generation and the reranker stay because nothing else serves them.
  • n8ndropped
    2024
    It got unwieldy as soon as anything got complex.
  • CrewAIdropped
    2024-08
    I evaluated it once and did not adopt it.
  • Headless Claude on the subscriptiondropped
    It is billed as API. Not being able to script the agent against itself, or define my own loops and monitors, is most of why the next thing exists.

How I use them

  • The agent is the nervous system, not an organ.
    It owns no state and does no single thing. It reads from every organ, composes them, and decides.
  • I generate more and select harder.
    I automate many experiments and filter the best, instead of thinking each one out.
  • I build the body, not the agent.
    The agent is a commodity. The product is the shell that comes alive when you put one in.
  • Systems that run matter more than tools.
    A system that runs, with a configuration space I can search, has done more for me than any single tool.
  • I verify the shipped surface myself.
    An agent reporting that its own work is done is not verification.
  • Everything is kernel mode with a coding agent.
    It gives maximum flexibility with no guardrails except version control.
  • I run agents from my phone.
    Sitting at a terminal stopped being a requirement in August 2026.
