Deep dive

On shared benchmark coverage, SWE-bench Verified has DeepSeek V3 0324 at 76.8 and GPT-4.1 Mini at 23.6, with DeepSeek V3 0324 ahead by 53.2 points; Aider Polyglot has DeepSeek V3 0324 at 55.1 and GPT-4.1 Mini at 32.4, with DeepSeek V3 0324 ahead by 22.7 points. The largest visible gap is 53.2 points on SWE-bench Verified, 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: GPT-4.1 Mini, multimodal input: GPT-4.1 Mini, function calling: GPT-4.1 Mini, tool use: GPT-4.1 Mini, structured outputs: GPT-4.1 Mini, and code execution: GPT-4.1 Mini. 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 GPT-4.1 Mini lists $0.40/1M input and $1.60/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek V3 0324 lower by about $0.23 per million blended tokens. Availability is 3 providers versus 4, so concentration risk also matters.

Choose DeepSeek V3 0324 when provider fit and lower input-token cost are central to the workload. Choose GPT-4.1 Mini when coding workflow support, 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 GPT-4.1 Mini?

GPT-4.1 Mini 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 GPT-4.1 Mini?

DeepSeek V3 0324 is cheaper on tracked token pricing. DeepSeek V3 0324 costs $0.27/1M input and $1.12/1M output tokens. GPT-4.1 Mini costs $0.40/1M input and $1.60/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is DeepSeek V3 0324 or GPT-4.1 Mini open source?

DeepSeek V3 0324 is listed under Open Source. GPT-4.1 Mini is listed under Proprietary. 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 vision, DeepSeek V3 0324 or GPT-4.1 Mini?

GPT-4.1 Mini has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.

Which is better for multimodal input, DeepSeek V3 0324 or GPT-4.1 Mini?

GPT-4.1 Mini has the clearer documented multimodal input signal in this comparison. If multimodal input 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 GPT-4.1 Mini?

DeepSeek V3 0324 is available on Fireworks AI, Microsoft Foundry, and Novita AI. GPT-4.1 Mini is available on OpenRouter, Replicate API, OpenAI API, and Vercel AI Gateway. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
