Frequently asked questions
Is DeepSeek V4 Pro as good as GPT-4?
DeepSeek V4 Pro is open-weight and competitive on many tasks, but GPT-4 may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Can I run DeepSeek V4 Pro locally?
Yes. DeepSeek V4 Pro has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. GPT-4 is API-only and cannot be self-hosted.
How much cheaper is DeepSeek V4 Pro?
DeepSeek V4 Pro costs $0.87/M output vs $60/M for GPT-4 — roughly 69x cheaper via API, and free if you self-host.
DeepSeek V4 Pro vs GPT-4 — which should I pick in 2026?
Choose DeepSeek V4 Pro if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose GPT-4 if you want frontier capability through a managed API with zero infrastructure to run.
