Deep dive

On shared benchmark coverage, SWE-bench Verified has DeepSeek V3 0324 at 76.8 and DeepSeek V4 Pro at 80.6, with DeepSeek V4 Pro ahead by 3.8 points; Google-Proof Q&A has DeepSeek V3 0324 at 87.6 and DeepSeek V4 Pro at 90.1, with DeepSeek V4 Pro ahead by 2.5 points; HumanEval has DeepSeek V3 0324 at 85.5 and DeepSeek V4 Pro at 76.8, with DeepSeek V3 0324 ahead by 8.7 points. The largest visible gap is 8.7 points on HumanEval, 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 V4 Pro, function calling: DeepSeek V4 Pro, tool use: DeepSeek V4 Pro, and structured outputs: DeepSeek V4 Pro. Both models share the core language-model surface, 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 V3 0324 lists $0.27/1M input and $1.12/1M output tokens on the cheapest tracked provider, while DeepSeek V4 Pro lists $0.43/1M input and $0.87/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek V3 0324 lower by about $0.04 per million blended tokens. Availability is 3 providers versus 5, so concentration risk also matters.

Choose DeepSeek V3 0324 when provider fit and lower input-token cost are central to the workload. Choose DeepSeek V4 Pro when reasoning depth, larger context windows, 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.

FAQ

Which has a larger context window, DeepSeek V3 0324 or DeepSeek V4 Pro?

DeepSeek V4 Pro supports 1m tokens, while DeepSeek V3 0324 supports 160k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, DeepSeek V3 0324 or DeepSeek V4 Pro?

DeepSeek V3 0324 is cheaper on tracked token pricing. DeepSeek V3 0324 costs $0.27/1M input and $1.12/1M output tokens. DeepSeek V4 Pro costs $0.43/1M input and $0.87/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is DeepSeek V3 0324 or DeepSeek V4 Pro open source?

DeepSeek V3 0324 is listed under MIT. DeepSeek V4 Pro is listed under MIT. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.

Which is better for reasoning mode, DeepSeek V3 0324 or DeepSeek V4 Pro?

DeepSeek V4 Pro has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Which is better for function calling, DeepSeek V3 0324 or DeepSeek V4 Pro?

DeepSeek V4 Pro has the clearer documented function calling signal in this comparison. If function calling is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Where can I run DeepSeek V3 0324 and DeepSeek V4 Pro?

DeepSeek V3 0324 is available on Fireworks AI, Microsoft Foundry, and Novita AI. DeepSeek V4 Pro is available on DeepSeek Platform, Fireworks AI, OpenRouter, Vercel AI Gateway, and Novita AI. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
