New LLM inference engine unum-rt shows speed gains under load

A new inference engine called unum-rt has been developed to improve local LLM decoding speeds, particularly under load. Benchmarks show unum-rt achieving 45.1 tokens per second when handling concurrent requests, significantly outperforming an open-source engine at 12.4 tokens per second. However, unum-rt is slower than the open-source engine when processing long, cold prompts, with the latter showing faster first-token arrival times and higher overall throughput. The developers emphasize that unum-rt's strengths align with their specific use case of overlapping AI agent requests, making it more suitable for their continuous workload. AI

IMPACT Offers potential for faster local LLM inference, especially in multi-request scenarios.

    3.6x faster local LLM decoding under load, and the six rows where we lose

    <p>We run a small crew of AI agents on one mini PC. Two requests are in flight most of the day, so the number we care about is not how fast a model decodes alone. It is how fast it decodes while another request is loading a long prompt. That is where we built our own inference en…
