Emo
Suggest emoji faster than you can type.
Multilingual on-device emoji suggestion.
- SDKs, install and examples: https://github.com/Desert-Ant-Labs/desert-ant-core/blob/main/docs/models/emo.md
- Website: https://desertant.com/models/emo/
Type a word or a sentence and get the emoji that fits. Tuned for to-dos, calendar entries, notes, and message drafts across 22 languages (including CJK, Arabic, Thai, Hindi, and more). The whole thing, model and tokenizer, is small (5MB on Apple via Core ML, 11MB via LiteRT elsewhere) and runs in well under 2ms on device.

Files
| File | Format | Size | Contents |

Inputs and outputs
- Input: a plain text string. Best on short, intent-oriented text.
- Output: a probability distribution over the 812-emoji vocabulary; take the top-1 (or top-k). Optimized for top-1 relevance.
Languages
English, Spanish, Portuguese, French, German, Italian, Dutch, Russian, Polish, Turkish, Arabic, Chinese (Simplified & Traditional), Japanese, Korean, Hindi, Indonesian, Thai, Vietnamese, Ukrainian, Swedish, Danish, Czech.
Limitations
- Tuned for short, intent-oriented text; long-form text produces noisier suggestions.
- Emoji semantics are imprecise; near-ties at the top of the ranking are expected.
- Per-language quality varies; lower-resource languages in the set are somewhat weaker.
