Key Features
1. Million+ Token Context Window
Process entire codebases in a single pass with context windows exceeding 1 million tokens. Enable true multi-file reasoning, understand relationships between components, trace dependencies, and maintain consistency across large-scale refactoring.
Prompt
Analyze my entire codebase (500+ files) and refactor the authentication module to use JWT instead of sessions, ensuring all dependent services are updated.
DeepSeek V4 Response
I've analyzed all 523 files in your codebase. Here's my refactoring plan: 1. auth/session.ts → auth/jwt.ts (new implementation) 2. 47 files need import updates 3. 12 API endpoints require middleware changes 4. 3 test files need updates Proceeding with changes...
2. Unbeatable Pricing
Get 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.

3. Coding Benchmark Champion
DeepSeek V4 scores 98% on HumanEval and 96% on GSM8K. It can diagnose and fix bugs spanning multiple files, analyze stack traces, trace execution paths, and propose fixes that account for full system context.
Multi-file Bug Fix
// V4 analyzes stack trace across 3 files: // Error in api/users.ts:47 ← calls auth/verify.ts:23 ← uses db/query.ts:89 // Root cause: Race condition in db/query.ts // Fix: Added mutex lock and retry logic // Updated 3 files, all tests passing ✓
4. Consumer Hardware Compatible
Run on consumer-grade hardware: dual RTX 4090s or a single RTX 5090 for the consumer tier. No need for expensive data center GPUs for local deployment.
5. Open Weights
Fully open-weight model continuing DeepSeek's tradition of accessible AI. Run V4 entirely within your own infrastructure for strict data governance requirements.
