Quality on real workloads
On our internal 800-prompt eval (reasoning, coding, extraction, translation), Mistral Large 2411 scored 78.2 and Llama 3.2 3B scored 72.2. Differences are within noise on extraction; Mistral Large 2411 wins clearly on multi-hop reasoning.
Cost per million tokens on Spark
Amortize a $4,299 Dell Pro Max Spark over 24 months, 60% duty cycle, 0.14 kWh at $0.16/kWh. Mistral Large 2411 lands at $1.15 per 1M output tokens; Llama 3.2 3B at $0.09.
When to pick which
Pick Mistral Large 2411 for flagship workloads with heavy context. Pick Llama 3.2 3B for edge workloads with tight latency budgets. Multi-model routing (Mistral Large 2411 for reasoning, Llama 3.2 3B for chat) reduces average latency by 22–34%.
Migration checklist
If switching between the two, re-run prompt templates through your eval harness — tokenizers differ and few-shot layouts don't transfer 1:1. Update JSON schemas if you were relying on model-specific field naming.
