DeepSeek V4: The Most Versatile Model You Can Run
Cheaper than GPT-5.5, versatile across tasks, and fully sovereign
Two Models, One MIT License
DeepSeek V4 launched April 24, 2026 in two variants: Flash for speed and throughput, Pro for peak reasoning. Both ship under the MIT license — no usage restrictions, no commercial limits, no vendor permission required.
Versatility Across Tasks
Coding and Engineering
V4 Flash Max scores 91.6% on LiveCodeBench. Pro Max hits 93.5%. Codeforces ratings of 3052 (Flash) and 3206 (Pro) place both in expert territory. From code reviews to greenfield development, these models deliver.
Reasoning and Research
Pro Max hits 90.1% on GPQA Diamond (graduate-level science) and 37.7% on HLE (humanity's last exam). Flash Max reaches 88.1% on GPQA Diamond. Three thinking modes — non-think, think high, think max — let you trade speed for depth.
Agentic Workflows
V4 Pro Max scores 67.9% on Terminal Bench 2.0 and 55.4% on SWE-bench Pro. Flash Max handles 56.9% on Terminal Bench. For tool use, multi-step planning, and autonomous workflows, both variants are production-ready.
Long-Context Processing
1M-token context windows on both models handle entire codebases, full document sets, and extended conversations without chunking. The hybrid attention architecture (CSA + HCA) reduces KV cache memory by 90% versus prior models.
The Data Sovereignty Spectrum
Open-source means you choose where inference happens. That choice has real consequences for your data.
DeepSeek Hosted API
Cheapest path, but data routes to servers in China subject to the National Intelligence Law. Chinese law can compel access to data processed on domestic servers. No data processing agreement overrides this.
Western Cloud Providers
Providers like Together AI and Fireworks host DeepSeek models on US or Canadian infrastructure. Data stays local, governed by that provider's jurisdiction and terms. A solid middle ground — but you still send data to a third party.
On-Premises with Faraday
Full data sovereignty. Inference runs on hardware you own, inside your network, behind your firewall. No third-party terms, no jurisdiction questions, no data processing agreements needed. Your data never leaves your control.
On-Premises vs Cloud
Cloud DeepSeek V4
