DeepInfra vs SiliconFlow — DeepSeek V3
The input/output cost of $0.27 per 1M tokens positions this API tier in the mid-range for its class, while the throughput of 480 tok/s is relatively fast. With rate limits of 15,000 TPM and 60 RPM, these constraints are more suited for low-volume prototyping rather than high-volume production, and the first-token latency of 350 ms is better aligned with batch use than real-time applications.
This API tier is suitable for a low-volume prototyping workload in a fine-tuned classifier serving architecture, targeting <50k daily completions.
With an input and output cost of $0.14 per 1M tokens, this pricing is mid-tier for a model with 685B parameters, while the throughput of 430 tok/s is relatively fast. The rate limits of 30,000 TPM and 60 RPM suggest suitability for low-volume prototyping, and the first-token latency of 380 ms is more favorable for batch use than for real-time applications.
This API tier is suitable for a batch document processing workload with a small team requiring <50k daily completions.
Frequently Asked Questions
