AILO-152M-Events-EN Natural language → calendar-event JSON ⚡

A 152M-parameter specialist that turns an English sentence into a clean event JSON — title, date, time, location, participants — and runs on almost anything.

This is a task-specialist built on AILO-152M. It does one thing and does it well: read an event description in plain English and output structured JSON. Tiny, fast, deterministic — ideal as the parsing brain of a calendar app, assistant, or automation.

ollama run Alieno/ailo-152m-events-en
>>> Lunch with Sarah tomorrow at 1pm at the new Italian place
{"title": "lunch", "date": "tomorrow", "time": "13:00", "location": "the new Italian place", "participants": ["Sarah"]}

Schema

{"title": str, "date": str|null, "time": "HH:MM"|null, "location": str|null, "participants": [str]}

time is normalized to 24h HH:MM — "at 3pm" → 15:00, "half past 7" → 07:30, "at noon" → 12:00.
date is extracted as written ("tomorrow", "next Friday", "March 15") — it is not resolved to a calendar date (the model has no clock).
Missing fields → null; no participants → [].

Benchmarks (held-out test set, 1500 unseen examples)

Metric	Score
Valid JSON	100%
Full object exact-match	83.7%
`title`	97.3%
`date`	88.3%
`time` (normalized)	100%
`location`	97.0%
`participants`	97.3%

It also generalizes to real, free-form sentences (it learned to copy spans, not classify to a fixed list): "Call mom tonight" → {"title": "call mom", ...}, "Birthday party Saturday at Jake's place with everyone" → {"title": "birthday party", "location": "Jake's place", "participants": ["everyone"]}.

Use it in an app

curl http://localhost:11434/api/chat -d '{
  "model": "Alieno/ailo-152m-events-en",
  "messages": [{"role": "user", "content": "Quick sync with the dev team Monday 10am on Zoom"}],
  "stream": false,
  "options": {"temperature": 0.0}
}'
# -> {"title":"quick sync","date":"Monday","time":"10:00","location":"on Zoom","participants":["the dev team"]}

Tags: :latest / :q8_0 (best, 156 MB) · :q4_k_m (smallest, 97 MB) · :f16 (291 MB). Run with temperature 0 for deterministic JSON. repeat_penalty is kept low (1.05) so JSON punctuation isn't penalized.

Details

Property	Value
Parameters	151.9M
Architecture	Decoder-only Transformer (LayerNorm · RoPE · SwiGLU), 12L/768/12H, ctx 512
Base	AILO-152M-v2 → specialized on event-extraction
Training	26k synthetic (sentence → JSON) pairs, open/compositional vocabulary (~2000 unique titles) so the model learns to copy spans
Formats	GGUF (q4_k_m, q8_0, f16) + PyTorch

Limitations

Dates are not resolved to absolute dates — the phrase is extracted as-is.
Unusual date phrasings ("the 23rd of March") may drop the day number.
Single event per input; English only; 512-token context (short sentences).
For exact calendar entries, resolve the relative date downstream with the user's timezone/clock.
