The Clear AI Team May 18, 2026 7 min read
Both models are on the Power tier, so the practical question is which one to reach for by default. Short answer: GLM-5.1 for structured reasoning, Llama-3.3 for open-ended writing.
GLM-5.1 wins at
- Multi-step math and formal logic
- Tool selection when many tools are available
- JSON output under a strict schema
Llama-3.3 wins at
- Long-form prose without slop phrases
- Following an unusual persona for many turns
- Following instructions that push against safety training
Our default
GLM-5.1 as the router default. Llama-3.3 when the request is explicitly creative or when GLM refused a legal-but-edgy request.
