Jev 1.14: What's New and How to Upgrade

Jev 1.14.0 brings small gains everywhere and the biggest gain in multilingual support. Same price as 1.13. Experimental images, box type and long context.

TypeSafe released Jev 1.14.0 on October 14, 2026. (Jev 1.14 release)

The release describes small, subtle improvements to everything, and TypeSafe expects the largest gain in multilingual support. (Jev 1.14 release)

The price and the default limits are the same as Jev 1.13.0. (Models)

At a glance

As of October 15, 2026, both jev-1.14.0 and jev-1.13.0 cost $42 per billion input tokens, equal to $0.042 per million input tokens, with output free. (Models)

The default context is 64k tokens per request and 32k tokens per question, and the documented default input is text. (Models)

jev-1.14.0 has been available since October 14, 2026. (Models)

On October 15, 2026, jev-latest points to jev-1.13.0 and is the stable SDK default, and jev-preview points to jev-1.14.0. (Models)

What changed in the model

TypeSafe describes small improvements across tasks. (Jev 1.14 release)

The largest expected gain is in multilingual support. (Jev 1.14 release)

English remains the primary training language, where accuracy is best. (Models)

Other languages, including CJK, are handled, but not equally well. (Models)

If you route non-English text, test your own content and watch the confidence values. (Models)

New experimental features (danger zone)

TypeSafe ships images, a box type, and longer context behind opt-in danger-zone headers. (Jev 1.14 release)

TypeSafe says there is too much jaggedness for it to vouch for these features in production use cases. (Jev 1.14 release)

• Images (experimental). Send the header TypeSafe-Danger-Zone-Images: true. (Jev 1.14 release) Images go in assets and can be referenced from state, instructions, or criteria. (Jev 1.14 release) The same header works on jev-1.13.0. (Jev 1.14 release) TypeSafe states that all models, Jev included, perform worse on multimodality than on pure text, so break questions into the simplest decompositions. (Jev 1.14 release) OpenRouter describes this multimodal support as experimental. (OpenRouter post)
• box type (experimental). The box type returns a single bounding box. (Jev 1.14 release) It is enabled only for jev-1.14.0. (Jev 1.14 release)
• Long context (experimental). Send the header TypeSafe-Danger-Zone-Long-Context: true. (Jev 1.14 release) The header works on both jev-1.14.0 and jev-1.13.0. (Models) With the header, both the per-request limit and the per-question limit are 262k tokens, the price per token stays the same, and responses are slower and less accurate. (Models)
• Opt-in debugging. You can opt in to share queries so TypeSafe can debug them. (Jev 1.14 release) TypeSafe states, “We will still not train on your queries.” (Jev 1.14 release)

How to upgrade

1. Check which model name your code sends.
2. To use 1.14 now, send jev-1.14.0 or jev-preview. (Models)
3. jev-latest moves to jev-1.14.0 around October 21, 2026, one week after the October 14, 2026 release. (Jev 1.14 release) If you send jev-latest, or you rely on the SDK default, the model you call changes on that move. (Models)
4. jev-1.13.0 stays available for a while. (Jev 1.14 release) To stay on 1.13, pin jev-1.13.0. (Jev 1.14 release) TypeSafe will give 60 days of warning before 1.13 is deprecated, and 30 days before 1.14 is deprecated. (Jev 1.14 release) TypeSafe will publish the deprecation policy before those warnings. (Jev 1.14 release)
5. If you tuned confidence thresholds on 1.13, send the versioned model id instead of an alias, and run your own evaluation set before you switch. (Models)
