Custom engine achieves 400 t/s for Qwen-Flash-Next on older hardware

By PulseAugur Editorial · [1 sources] · 2026-10-26 21:11

A user has developed a custom engine designed to run the Qwen-Flash-Next large language model at a high speed of nearly 400 tokens per second. This performance was achieved using a setup of three V100 32GB GPUs within an older R740 server. The engine is a fork of the strata project, with significant modifications made to its core components to optimize for the Volta generation of GPUs. AI

IMPACT Demonstrates potential for optimizing LLM inference speed on consumer-grade hardware.

RANK_REASON User-developed optimization for running an existing LLM on specific hardware.

Custom engine achieves 400 t/s for Qwen-Flash-Next on older hardware

How we ranked this

Signal score: 2 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; User-developed optimization for running an existing LLM on specific hardware.
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: infra, model release; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Same-day; Cluster formed today. Ranking reflects the current source set at time of score.

I built an engine that runs Qwen-Flash-Next at nearly 400t/s on cheap(ish) hardware. 3x V100 32GB in an old R740. Originally forked from strata but the engine guts all built for the old Volta generation.
