SGLang benchmarks DeepSeek V4.1 Flash: up to 1.04× prefill, 7.4% shorter decode
SGLang reports up to 1.04× DeepSeek's in-house prefill throughput on four B300/GB300 GPUs and up to 7.4% shorter decode steps on 64 GB300s, with vLLM matching DeepInfer's decode curves.
🔔 The Daily Semi-Cap — October 24, 2026 📊 SMH: $527.20 (last market close: October 23, 2026; +0.74% vs October 22 close) • Open inference engines are catching DeepSeek’s in-house stack. SGLang’s new DeepSeek-V4.1-Flash benchmarks show up to 1.04× prefill throughput on four B300/GB300 GPUs and up to 7.4% shorter decode steps on 64 GB300s. vLLM also matched DeepInfer’s decode curves. These are specific benchmark configurations, not universal production gains, but faster serving can improve the economics of installed accelerators without waiting for new silicon. • Datacenter opposition cuts across party lines: 63% of voters oppose an AI facility near home, versus 13% supporting one. Even among MAGA supporters, 40% oppose a facility within 10 miles, against 29% supporting it. The proximity question covered roughly 500 voters. For infrastructure suppliers, this highlights a project-timing risk: enthusiasm for AI does not automatically translate into local permission to build its power-hungry physical footprint.
