| Architecture | MoE | Dense |
Quality on real workloads
On our internal 800-prompt eval (reasoning, coding, extraction, translation), DeepSeek Coder V2 236B scored 83.8 and Llama 3.3 70B scored 75.5. Differences are within noise on extraction; DeepSeek Coder V2 236B 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. DeepSeek Coder V2 236B lands at $0.84 per 1M output tokens; Llama 3.3 70B at $0.57.
When to pick which
Pick DeepSeek Coder V2 236B for code workloads with heavy context. Pick Llama 3.3 70B for dense-reasoning workloads with tight latency budgets. Multi-model routing (DeepSeek Coder V2 236B for reasoning, Llama 3.3 70B 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.
