DeepSeek V4 — Advanced AI Language Model for Code & Reasoning
The ultimate coding AI with 1M+ token context window, 98% HumanEval score, and open weights. State-of-the-art performance at 40% the cost of competitors.
Why DeepSeek V4
Next-gen AI model with unprecedented coding abilities, million-token context, and open weights — running at a fraction of the cost.
Million+ Token Context Window
Process entire codebases in a single pass. Enable true multi-file reasoning, understand relationships between components, trace dependencies, and maintain consistency across large-scale refactoring.
Unbeatable Pricing
State-of-the-art performance at just $0.10 per million tokens — 40% of the inference cost of comparable models like Claude Opus 4.5 and GPT-4.5 Turbo.
Coding Benchmark Champion
98% on HumanEval and 96% on GSM8K. Diagnose and fix bugs spanning multiple files, analyze stack traces, trace execution paths, and propose fixes that account for full system context.

FAQ
DeepSeek V4 is the latest flagship AI model from DeepSeek, featuring over 1 million token context, 98% HumanEval coding benchmark, and the ability to run on consumer GPUs with open weights.
DeepSeek V4 outperforms both on coding benchmarks while running at 40% of their inference cost. It features a much larger context window (1M+ tokens) and can run on consumer hardware.
Yes. DeepSeek V4 is designed to run on consumer-grade hardware. The consumer tier requires dual RTX 4090s or a single RTX 5090. Open weights allow full local deployment.
V4 can process entire codebases in one pass, understand multi-file relationships, diagnose cross-file bugs, and maintain consistency across large refactoring operations — all at 98% HumanEval accuracy.
DeepSeek V4 costs $0.10 per million tokens on WaveSpeed — approximately 40% of comparable models. Visit the pricing page for current rates.
Yes. DeepSeek V4 has fully open weights, continuing DeepSeek tradition. You can run it entirely within your own infrastructure for strict data governance requirements.
