Writer introduces new AI model and upgraded harness to contain token costs
Writer cuts token costs with a custom model variant built on GLM-5.2 — deployment economics matter more than raw capability now.

Why it matters
A vendor shipping a tuned model variant and inference optimization ('harness') to reduce operational cost per deployment. Practitioners budgeting AI services will track this pricing/efficiency play; less about frontier capability, more about practical deployment economics.
