# Flan-T5 Base — ONNX

ONNX export of [Flan-T5 Base](https://huggingface.co/google/flan-t5-base) (250M parameters) with encoder-decoder architecture and KV cache support.

Converted for use with [inference4j](https://github.com/inference4j/inference4j), an inference-only AI library for Java.

## Usage with inference4j

```java
// Summarization
try (var gen = FlanT5TextGenerator.flanT5Base().build()) {
    System.out.println(gen.summarize("Long article text..."));
}

// Translation
try (var gen = FlanT5TextGenerator.flanT5Base().build()) {
    System.out.println(gen.translate("Hello!", Language.EN, Language.FR));
}
```
