+Paper: [ELECTRA: Pre-training Text Encoders as Discriminators Rather Than Generators (arXiv:2003.10555)](https://arxiv.org/abs/2003.10555) · [HF Papers](https://huggingface.co/papers/2003.10555)
+
+ELECTRA is Google's BERT-style bidirectional text encoder, pre-trained as a replaced-token **discriminator** (with a smaller **generator** producing the corrupted tokens). This repo is the **encoder / downstream** checkpoint. WordPiece tokenizer; mask token `[MASK]`.
+
+For more details on the model, please go to the upstream [model card](https://huggingface.co/google/electra-small-discriminator).
+
+Pure-**Keras 3** conversion of [`google/electra-small-discriminator`](https://huggingface.co/google/electra-small-discriminator) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**.
+
+## ✨ Quick start (encoder / downstream)
+
+```python
+import os
+os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"
+
+from kerasformers.models.electra import ElectraModel, ElectraTokenizer
+
+model = ElectraModel.from_weights("kerasformers/electra_small_discriminator")
+tokenizer = ElectraTokenizer.from_weights("kerasformers/electra_small_discriminator")
+
+out = model(tokenizer("The quick brown fox."))["last_hidden_state"]  # (1, L, H)
+```
+
+The same repo also serves the task heads, loaded the same way: `ElectraSequenceClassify`, `ElectraTokenClassify`, `ElectraQnA`, `ElectraMultipleChoice` (each takes the pretrained encoder and a randomly-initialized head, ready for fine-tuning).
+
+Load any ELECTRA variant the same way with `from_weights("kerasformers/<variant>")`:
+
+| Size | Discriminator (encoder / downstream) | Generator (masked-LM) |
+|---|---|---|
+| small | [`kerasformers/electra_small_discriminator`](https://huggingface.co/kerasformers/electra_small_discriminator) | [`kerasformers/electra_small_generator`](https://huggingface.co/kerasformers/electra_small_generator) |
+| base | [`kerasformers/electra_base_discriminator`](https://huggingface.co/kerasformers/electra_base_discriminator) | [`kerasformers/electra_base_generator`](https://huggingface.co/kerasformers/electra_base_generator) |
+| large | [`kerasformers/electra_large_discriminator`](https://huggingface.co/kerasformers/electra_large_discriminator) | [`kerasformers/electra_large_generator`](https://huggingface.co/kerasformers/electra_large_generator) |
+
+## Tips
+
+- Set `KERAS_BACKEND` **before** importing Keras / kerasformers.
+- Prefer `ElectraTokenizer.from_weights(...)` so WordPiece tokenization matches.
+- Downstream tasks (classification / QA / NER) use the **discriminator** repos; the **generator** repos are the masked-LM.
+- See [ELECTRA docs](https://imvision12.github.io/KerasFormers/electra/) and [Loading Weights](https://imvision12.github.io/KerasFormers/loading_weights/).
+- Community / upstream safetensors still work via the `hf:` prefix, e.g. `ElectraModel.from_weights("hf:google/electra-small-discriminator")`.

+## Special Thanks
