Smashing the Tariffs for Fun and Profit: How DeepSeek v3 Outsmarted the AI Ban

1. CUDA and PTX Optimizations

DeepSeek-V3’s engineers optimized GPU performance at the low-level by tailoring kernels and memory access patterns to NVIDIA’s hardware. A key strategy was warp specialization: they partitioned a subset of GPU threads (warps) specifically for communication tasks, allowing compute to overlap with data transfers (DeepSeek-V3 Technical Report). In practice, only ~20 of the GPU’s Streaming Multiprocessors (SMs) were reserved to handle all cross-node communications – enough to saturate both InfiniBand (IB) and NVLink bandwidth – while the remaining SMs focused purely on computation (DeepSeek-V3 Technical Report) ([DeepSeek-V3 Technical Report](https://arx

name	cove-validate
description	Chain-of-Verification validation for any claim, output, plan, or code change. Use when the user says "validate", "verify", "check this", "is this right", "CoVe", or when you need to rigorously verify correctness of something before presenting it as fact. Also use proactively before committing code, finalizing plans, or asserting factual claims that could be wrong.

Apply the Chain-of-Verification (CoVe) framework to rigorously validate a target claim, output, or artifact. CoVe works by generating independent verification questions and answering them without bias from the original draft, then synthesizing a verified result.

When to use
