Deep dive
On shared benchmark coverage, Google-Proof Q&A has DeepSeek R1 0528 at 81 and Llama 2 13B Chat at 41.8, with DeepSeek R1 0528 ahead by 39.2 points. The largest visible gap is 39.2 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on reasoning mode: DeepSeek R1 0528 and code execution: DeepSeek R1 0528. Both models share structured outputs, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, DeepSeek R1 0528 lists $0.50/1M input and $2.15/1M output tokens on the cheapest tracked provider, while Llama 2 13B Chat lists $0.10/1M input and $0.50/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Llama 2 13B Chat lower by about $0.77 per million blended tokens. Availability is 6 providers versus 11, so concentration risk also matters.
Choose DeepSeek R1 0528 when coding workflow support and larger context windows are central to the workload. Choose Llama 2 13B Chat when provider fit, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
