OpenJet engine enables 4 coding agents on one RTX 3090 at 290 tok/s

A new custom CUDA engine called OpenJet has been developed to run multiple coding agents concurrently on a single GPU, specifically an RTX 3090. This engine allows for a total throughput of approximately 290 tokens per second across four agents, which is a significant improvement over existing solutions like llama-server that achieve around 72-80 tokens per second for the same configuration. The engine achieves this by batching the work of multiple agents into a single CUDA kernel, optimizing memory bandwidth usage and reducing the cost of loading model weights. AI

IMPACT Enables more efficient local deployment of multiple AI agents on consumer hardware.

RANK_REASON New software/engine release for running existing models.
