Today on The Bandwidth-Bound: empirical evaluations show floating-point precision discrepancies are breaking 'lossless' speculative decoding guarantees in production, while statistical audits reveal S…
When experimental recurrence models and aggressive quantization hit production serving engines, the fault lines are usually found at the lowest levels of state management. Today on The Bandwidth-Bound…
State continuity is finally catching up to hybrid architectures. As vLLM proposes direct slot transfers for Mamba models, we're also tracking how strict reliance on static decoder metrics misses the v…
Today on The Bandwidth-Bound, we track a growing friction point in open-weight inference: as multi-agent frameworks scale concurrent tool execution, local serving engines are facing severe correctness…
The barrier between foundational models and custom hardware is collapsing. Moonshot AI's Kimi-K3 just generated synthesizable RTL for a custom hybrid inference chip, while systems engineers at Cohere …
DeepSeek is establishing new baselines for KV cache efficiency with an asymmetric causal encoder-decoder architecture that aggressively shrinks memory demands. We are also reviewing empirical GGUF lay…
Alibaba just pushed open-weight architectures past the two-trillion parameter threshold, setting the stage for today's developments in local serving hardware. We're also tracking DeepSeek's new asymme…
Today on The Bandwidth-Bound: systems researchers are tackling local inference limits through host-RAM co-execution and disk-streamed experts, while interpretability evaluations reveal hard limits in …
We're continuing to track the pivot toward hyper-optimized local inference. Following yesterday's breakdowns of DeepSeek's KV cache reductions, today brings new methods for memory-mapping heavy embedd…
As long-context generation increasingly collides with hardware limits, researchers are finding architectural escape hatches. Today's developments center on DeepSeek's low-rank KV compression, hardware…
