The llama.cpp project released a new version (b11707) that adds a feature called GraniteSwitchDecisionFullOptions. It lets each switch model use up to 256 unique single‑token markers instead of the previous 66. The code automatically discovers which characters form single‑token entries for a given model’s vocabulary. This change is in the C++ conversion layer and is documented in the release notes.

## The facts

- Release tag b11707 published on 2026-10-17
- Support increased from 66 to up to 255 unique single‑token markers

## Why it matters

Developers can build richer decision‑making prompts for Granite models without manually crafting token lists.
