Introduction

This project is a Cloudflare serverless worker with an AI service binding deployed for processing either audio, image or text submitted by users into semantic useful information, especially in the context for submitting expenses.

For users that prefer a UI, a simple NextJS web app is created to demonstrate how to upload files and utilizes API routes to make a POST request to the Cloudflare worker endpoint.

How it works

Models used

From Cloudflare AI Models:

• Image-to-text: @cf/unum/uform-gen2-qwen-500m
• Automatic Speech Recognition: @cf/openai/whisper
• Text Generation: @hf/thebloke/mistral-7b-instruct-v0.1-awq

Try out the worker!

The worker is deployed at https://cf-journal.senchatea.workers.dev.

Text input

curl --location 'https://cf-journal.senchatea.workers.dev?type=text' \
--header 'Content-Type: text/plain' \
--data '2 weeks ago, I went to eat a buffet at Swensens Unlimited at the T2 airport, it'\''s really nice but it costs like $36 per person after GST, and there were 2 of us.'
