Why TypeSafe's Jev decision model cuts LLM bills by up to three quarters, and how sub-500ms latency unlocks industrial AI use cases across UAE and GCC sites.

Jev's 444x cheaper claim, checked against TypeSafe's own evals: which model it's compared to, where Jev loses on invoices, and what the accuracy numbe

When your LLM bill moves, three separate things could have caused it. Your usage changed, your pricing changed, or the way your app talks to the model changed. Mixing them up is how teams end up thanking the wrong lever. A simple framework for pulling them apart.

Token savings are easy to market and hard to bank. Here’s the benchmark framework I trust for RTK-style compression: cost-per-success, tool-call failures, and latency.
