DeepSeek V4 Pro 0813 DeepSeek V4 Pro 0813 is a new AI model hosted by OpenRouter, with pricing, performance metrics including throughput, latency, and TTFT, uptime statistics over the last 30 days, and public app usage data. The model is available via OpenRouter's OpenAI-compatible API, allowing developers to integrate it by simply changing the model slug. This model is hosted by one provider. OpenRouter forwards every request to it directly — no routing decisions to make. Pricing The average price customers actually pay for this model, next to the prices providers post. Caching and discounts mean the price actually paid is often well below the listed one. Performance Throughput is how fast the model writes tokens per second — higher is better . Latency is total round-trip time lower is better . TTFT is time-to-first-token — how long before you see anything appear lower is better . Uptime Percent of requests that succeeded over the last 30 days. OpenRouter monitors every provider continuously and automatically retries on the next-best provider when one returns an error. Apps Public apps that send the most traffic to this model. Good signal for what real production workloads look like — and a hint at which use cases this model is best suited for. Activity Token volume and request traffic to this model over time. Quick Start Drop-in code to call this model. OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. The only thing that changes between models is the model slug below.
