Highlights
- jev-latest and jev-preview both point at jev-1.13.0; there is no separate preview build.
- Output tokens are free; only input is billed, at $42 per billion tokens.
- 64k context covers 32k of state plus the longest question.
- Rate limits adjust dynamically and can change without notice.
Quickstart
python
from typesafe_sdk import TypeSafeClient
with TypeSafeClient() as client:
for model in client.models.list().models:
print(model.name, model.release_date, model.description)Watch out
English is the primary language and non-English accuracy is lower, so test before relying on it for other languages.
Questions about this entry
Short answers drawn from the linked project or page.
Nothing. The card says output tokens are free and only input is billed, at $42 per billion tokens, which is why adding questions to a request changes the bill far less than enlarging the state.
Not today. Both aliases point at jev-1.13.0 on the card, and the docs say jev-preview only moves ahead of jev-latest when a preview build is actually available. Pin a version ID in production so a release cannot shift your thresholds.
Every model is served by the same endpoint, POST /v1/systemone, and the request's model field selects which one handles the call.
A request over either the 100K-tokens-per-second or 80-requests-per-second limit returns 429 Too Many Requests; the client SDKs retry with backoff by default and honor the retry-after header when present.
No. It is not fine-tuned or LoRA-adapted with customer data; it is trained with RLCD to return calibrated decisions, and the same weights serve every account.
English is the primary training language and where accuracy is best; other languages including CJK scripts are handled but not equally well, so test on your own content and pay attention to confidence when routing.
The names your account can send in the model field, with a description and release date for each. It currently lists the aliases, though versioned IDs like jev-1.13.0 are accepted whether or not they appear.
