philipkiely · x · 2026-08-14
An overview of the inference engineering work done to optimize DeepSeek V4 Pro 0813.
Model & Tooling Release
- DeepSeek V4 Pro 0813 weights are open-sourced under the MIT license, allowing unrestricted enterprise use and fine-tuning for the 1.7T-parameter model.
- Released alongside a new coding harness with a plugin-first architecture.
- The model sits alongside GLM-5.2 in quality on Artificial Analysis’ index but at a lower cost per task.
Inference & Deployment
- Available via Model API on Baseten with zero data retention by default.
- The post details the underlying engineering required to run this massive frontier model efficiently.
