What it does

Turn a sentence into emojis. 4 MB model.

  • Trained from scratch: a 3-layer T5 (d_model 128, 8k shared vocab) on ~490k text/emoji pairs from the Text2Emoji dataset. Recipe in training/text2emoji.
  • English input. Output is a short sequence of distinct emojis; maxEmojis caps the length (default 12).
  • Weights download from the Hugging Face Hub (midudev/text2emoji-tiny). To self-host, copy the folder and pass modelPath plus model (the folder name).

Questions about Emojify

Does Emojify run on device?

Yes. Weights download once and stay in the browser. Nothing is sent to a server.

Which model does Emojify use?

text2emoji-tiny (T5, 2.4M params, from scratch) by runonweb · data: Text2Emoji (KomeijiForce), under MIT. runonweb loads the midudev/text2emoji-tiny weights and runs q8 on WASM.

How big is the Emojify download?

~4 MB, fetched once on first use. The browser caches the weights, so later loads skip the network and keep working offline.

What does Emojify cost?

Nothing. runonweb is free and MIT-licensed, with no device limits, tokens or sign-in. The weights keep their own license: MIT.

Which browsers support Emojify?

Any modern browser with WebAssembly. This model does not use WebGPU yet: it fails at session creation in ONNX Runtime Web, so runonweb pins it to WASM.

Can I use a different model with runonweb/emoji?

Yes. See each module’s docs for the options it accepts (model, size, language…). Check the license and test both backends before shipping.
