DeepInfra Serves GLM-5.3 on NVIDIA Blackwell with Zero Data Retention and Explicit Cache Pricing

DeepInfra deployed GLM-5.3 on day zero utilizing NVIDIA Blackwell infrastructure in the US with Zero Data Retention (ZDR), publishing transparent pricing with an ultra-low $0.26/1M cached token tier.

Key Takeaways

  • Leverages US NVIDIA Blackwell hardware to maximize inference throughput and minimize time-to-first-token;
  • Explicit caching tier at $0.26/1M tokens drastically lowers operational costs for iterative agent loops;
  • Zero Data Retention (ZDR) guarantee provides stringent privacy compliance for enterprise codebases.
