About
- Founder & CEO of PRAVIEL: ancient languages, spoken aloud again. Live on iOS, Android, and the web.
- AI/ML and software engineer. Master's in AI from Tokyo Tech (speech recognition), production ML at Quantiphi, then LLM agents and safety research. I take contract work too.
- Open source. Small tools for people who build with LLMs, and fixes merged into ESPnet, Kornia, Pipecat, raylib, and others.
- AGI has had my attention for over a decade. As a kid I meant to be a physics professor, until I figured physics would get further with AI. Still into physics, math, philosophy, history, and music.
PRAVIEL
The old languages, out loud again.
Latin, Ancient Greek, and nine other ancient languages, taught the way apps teach the living ones: short daily lessons, reconstructed pronunciation you can hear, conversations with historical personas, and real texts you can take apart word by word. Built for beginners, drawn from curated sources. Free on web, iPhone, and Android.
Open source
Small tools, MIT-licensed, most of them running in the browser with nothing to install; four also run as Hugging Face Spaces. The whole shelf, with pictures: antonsoo.github.io/officina.
| Repository | What it is |
|---|
| contextscope | What fills an LLM context window, and why the prompt cache keeps missing. |
| mcplint | Lints an MCP server's tools the way the model reads them. |
| trainspotter | Reads a training run's logs and names what went wrong. |
| mergeglass | Checks whether a LoRA update survived the merge, weight by weight, or quietly rounded away. |
| flakemap | Finds the flaky tests in a CI history, with honest error bars. |
| logdelta | Diffs logs by meaning, to show what the failing run did that the good one did not. |
| ghostchars | Finds the characters you cannot see: Trojan Source, invisible Unicode, smuggled prompts. |
| stutterscope | The stutter that an average frame rate hides. |
| am-i-unlucky | Exact drop-rate and pity math: unlucky, or is it the system? |
| Repository | What it is |
|---|
| stoicheia | Euclid, Archimedes, and Pappus in Greek, Latin, and English, with working diagrams and the original printed pages. |
| zygon | Archimedes' balance and floating bodies: operate them first, then read the conditions in Greek. |
| gonia | Measured experiments in ancient architecture, from the Doric corner problem to Vitruvius' Ionic volute. |
| syngraphe | Turns a Greek building specification, the Piraeus naval storehouse, into a measured drawing. |
| dioptra | Hero's tunnel survey and distance counter, and Frontinus' Latin water pipes, tested by trial. |
| pnigeus | The air regulator inside an ancient water organ, as Hero and Vitruvius describe it. |
| pyknon | The ancient Greek interval that vanishes between modern piano keys, made audible. |
| sammu | An Old Babylonian procedure for retuning nine strings, one at a time, from manuscripts found at Ur. |
| seked | Pyramid slopes from the Rhind papyrus in exact fractions, with the scribe's discrepancies left in. |
Upstream fixes
Merged into other people's projects by their maintainers. Three favorites:
- ESPnet (#6865): a training run that had stopped early trained one more epoch every time it was resumed. Stopped now means stopped.
- Pipecat (#5989): Deepgram's HTTP voice could end a chunk halfway through a 16-bit sample, and a voice agent could go mute for the rest of the call.
- raylib (#6198, #6199): BDF fonts load without crashing, and a malformed OBJ model no longer sends the loader reading past its own vertices.
Live: every merged pull request, or all of them, open and closed.
A new line every morning. The small word in the lower margin is tomorrow's first.
A serpent once grazed the offerings at Anchises' tomb (Aeneid 5.84-96). This one grazes on commits.
Drawn by code in /scripts, Greek and all.
