App
This app asks Jev, a decision model of TypeSafe, a question about each image or text in a set. For each input, it shows the answer and the probability of each answer. It also gives the R code of the run and a bundle with the setup and the answers. You need no key and no account.
Help video
A 5-minute video shows how to use the app: a sample of images, your own images, a text sample and your own texts. It explains the three question types (Yes / no, Choice and Score), the answers and the R code. Watch it here, or on YouTube with chapters.
Package
The app uses the R package decisions, version 0.1.0. The package record shows how the package was made and tested. The method comes from the paper "Beyond CLIP: Calibrated (Few-Shot) Defect Detection With Structured Decision Models" (in preparation). The project record holds its decisions and its data.
Model
Each call goes to jev-1.14.0. The app sends each image with a longest side of 768 pixels. It shows the raw probabilities of Jev. They are not calibrated. The package can calibrate them.
Limits
- Each file: 5 MB. Each zip file: 50 MB.
- Each run: 100 images or 200 texts. Each text: 4,000 characters.
- Instructions: 500 characters. Each description: 300 characters.
- Choice: 2 to 6 answers. Score: 2 to 5 levels. References: at most 2 for each answer.
- Cost: USD 0.25 for each visit, USD 2 each day and USD 20 each month for all visitors together (UTC). When a limit is reached, the samples and the R code still work.
- The app estimates the cost from the input tokens, at USD 0.042 for each million tokens.
Privacy
Your images, texts and references go to TypeSafe (Jev). Do not upload confidential data. The app keeps no input after your session. It stores only the daily totals of calls, tokens and cost. The bundle and the logs hold no key.

Uptime
A GitHub workflow opens this app twice a day, as a visitor does. Each visit adds a row to a public file. The visit also keeps the app awake. The table shows the last 60 visits.
