COOLJEV / PRACTICAL GUIDE
Jev download: free handbook PDF and Python examples
Download the English handbook (59-page PDF) · Download the Chinese handbook (51-page PDF) · Download the Python examples (ZIP)
These free CoolJev downloads contain learning material and runnable application examples. They contain no Jev model weights. Running the examples offline replays authored responses; it does not run Jev inference on your computer.
Choose the file you need
| Download | Contents | What you can do without an account |
|---|---|---|
| English PDF | Complete 59-page handbook | Read and retain the integration explanations |
| Chinese PDF | Complete 51-page handbook | Read the same learning path in Chinese |
| Python ZIP | Seven standard-library command cases, inputs and fixtures | Run the local workflows with authored responses |
The handbook is independently written by CoolJev, not an official TypeSafe publication. The Python download is an educational HTTP client, not a model installer or the official TypeSafe SDK. There is no account or payment step for these files.
Run a downloaded example
Extract the ZIP, open a terminal in the directory containing examples/, and use Python 3.10 or later:
python3 -m examples.hello_jev tickets --mode offline --output examples/output/download-check.json
No package installation or API key is needed for this command. It writes a JSON report; open it and inspect the evidence field, individual records and review queue. A successful exit means the report was written, not that every item was approved. Repeating the command replaces the selected output file.
The seven cases are tickets, content, route, leads, reviews, articles and support. The last four include English and Chinese teaching inputs. See the Python command guide for the matching inputs and options.
What “offline” means here
Offline mode uses responses written by the author and tied to the supplied inputs. It verifies file handling, validation, rules and review paths. It does not test model accuracy, speed or cost. Editing the material invalidates its existing fixture; changing the fixture yourself still does not produce a model evaluation.
The examples also do not send customer messages, execute refunds or publish articles. Their output is a local report or a suggestion for review.
Use the real API separately
For actual Jev evaluation, obtain your own TypeSafe access, follow the ZIP README to set TYPESAFE_API_KEY, and explicitly select --mode live. That sends material to TypeSafe and can incur provider charges. The program does not load .env files automatically.
The official API reference documents the service request and typed answers; the official model reference describes supported inputs and pricing. Those service details are separate from downloading this handbook or replaying an offline example. Follow the first-run tutorial to move from a local walkthrough to an intentional live call.
