Swipe Keyboard trained models, 2026-10-23

Models trained and released by Destin Moss via youcoded.ai, 2026. SPDX-FileCopyrightText: 2026 Destin Moss https://youcoded.ai

Four neural next-word models (English, Spanish, French, German) and one swipe-recognition model. They sit beside the language files published in release language-files-2026-10-22-open-words and are checked by SHA-256 against packaging/assets.lock.json in github.com/itsdestin/swipe-keyboard before use. A missing or damaged file only turns that model off (suggestions fall back to the n-gram files; swipes fall back to the geometric matcher); it never disables a language.

File	What it is	Declared licence
`LANG.nwp.bin` (en, es, fr, de)	next-word model: a small recurrent network (one LSTM layer, integer weights, about 4.7 MB), used together with `LANG.ngram`	ODC-By-1.0 AND CC-BY-2.0-FR
`swipe-model.bin`	swipe recognition: small convolution + recurrent network (about 0.5 million weights, 2.1 MB) shared by all four languages	MIT

How they were built

Scripts in github.com/itsdestin/swipe-keyboard (commit 14f9722 and its ancestors on branch feature/179-engine-in-keyboard):

Next-word models: scripts/lm/nwp/prepare.py (tokenise, vocabulary), train.py (train), tune.py (blend with the n-gram), export.py (write LANG.nwp.bin). Training text: the same FineWeb (English, sample-10BT) / FineWeb-2 (Spanish, French, German) text and Tatoeba sentences as the n-gram files, with test sentences held out (Tatoeba ids ending in 0, and sentences sharing an 8-word run with the test sets).
Swipe model: scripts/swipe/prep_data.py, assemble_futo.py, synth_swipes.py, train.py. Training data: real swipes from FUTO's swipe.futo.org dataset (MIT) plus synthetic swipes generated from our open word lists (our own noise model, no FUTO code or model weights). Sessions used for validation or final scoring were held out.

Synthetic swipes (swipe model) - generated by us from the open word lists above; no third-party terms.

Changes made: text was split into sentences and reduced to letter words before training; swipes were resampled and normalised to key positions; the trained weights were converted to the compact formats the keyboard reads. These models contain no FUTO model weights and no FUTO code. https://github.com/itsdestin/swipe-keyboard
