Deep dive
On shared benchmark coverage, MMLU PRO has DeepSeek V4 Flash at 86.2 and Llama 4 Maverick 17B Instruct FP8 at 80.5, with DeepSeek V4 Flash ahead by 5.7 points; Google-Proof Q&A has DeepSeek V4 Flash at 88.1 and Llama 4 Maverick 17B Instruct FP8 at 67.1, with DeepSeek V4 Flash ahead by 21 points; LiveCodeBench has DeepSeek V4 Flash at 91.6 and Llama 4 Maverick 17B Instruct FP8 at 43.4, with DeepSeek V4 Flash ahead by 48.2 points. The largest visible gap is 48.2 points on LiveCodeBench, 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 vision: Llama 4 Maverick 17B Instruct FP8, multimodal input: Llama 4 Maverick 17B Instruct FP8, reasoning mode: DeepSeek V4 Flash, function calling: DeepSeek V4 Flash, and tool use: DeepSeek V4 Flash. 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 V4 Flash lists $0.10/1M input and $0.20/1M output tokens on the cheapest tracked provider, while Llama 4 Maverick 17B Instruct FP8 lists $0.15/1M input and $0.60/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek V4 Flash lower by about $0.16 per million blended tokens. Availability is 5 providers versus 10, so concentration risk also matters.
Choose DeepSeek V4 Flash when reasoning depth and lower input-token cost are central to the workload. Choose Llama 4 Maverick 17B Instruct FP8 when vision-heavy evaluation 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.
