# Leanstral 1.5

> A lean, efficient text model from Mistral, optimized for low-latency generation with strong cache-hit performance. vLLM/Requesty require top_p=1 with temperature=0; request-builder injects that pairing.

**Category**: text  
**Context**: 33K tokens  
**Status**: Disabled (since 2026-08-24) — no longer routable or listed; kept for history/usage reference.
