DeepSeek-V4: The Era of Cost-Effective 1M Context
24 April 2026•2 min read

DeepSeek announced DeepSeek-V4 Preview today, marking a significant milestone in open-source AI. With a massive 1M context length and parameters ranging up to 1.6T (MoE), the V4 series brings flagship-level intelligence to developers with unprecedented cost-effectiveness.
Both variants are now available on Cencori:
deepseek-v4-pro: 1.6T total / 49B active params. Rivaling the world's top closed-source models.deepseek-v4-flash: 284B total / 13B active params. Your fast, efficient, and economical choice.
Performance Reimagined
DeepSeek-V4 represents a leap in efficiency. By utilizing advanced Mixture-of-Experts (MoE) architectures, these models provide high-density intelligence while maintaining low inference costs.
Key Highlights:
- 1M Context Window: Process entire codebases, long legal documents, or complex research papers in a single prompt.
- Expert Mode (Pro): Optimized for complex reasoning, coding, and mathematical tasks.
- Instant Mode (Flash): Sub-second response times for high-volume applications and chat.

As part of the Cencori model catalog, DeepSeek-V4 benefits from our built-in reliability features:
- Automatic Failover:
deepseek-v4-proautomatically fails over togpt-5orclaude-opus-4.5if the primary provider experiences downtime. - Security & Governance: All requests are checked against your custom data rules and logged for audit trails.
- Semantic Caching: Reduce latency and costs for repetitive 1M-context queries.
