SGLang: An Open-Source Implementation Matching DeepSeek LLM's Inference Performance

DeepSeek, a popular open-source large language model (LLM), boasts impressive performance. However, its massive size and unique architecture (using Multi-head Latent Attention and Mixture of Experts) demand a sophisticated system for efficient large-scale serving. This blog details how we achieved near-parity with DeepSeek's inference system performance using SGLang. Our implementation, running on 12 nodes (each with 8 H100 GPUs) in the Atlas Cloud, leverages prefill-decode disaggregation and large-scale expert parallelism (EP), reaching 52.3k input tokens/second and 22.3k output tokens/second per node for 2000-token input sequences. This is, to our knowledge, the first open-source implementation to nearly match DeepSeek's reported throughput at scale, at roughly one-fifth the cost of the official DeepSeek Chat API.

Efficient Rubik's Cube Solving via Learned Representations: No Hand-Crafted Heuristics Needed

2025-08-29

Classical AI separates perception (spatial representation learning) from planning (temporal reasoning via search). This work explores representations capturing both spatial and temporal structure. Standard temporal contrastive learning often fails due to spurious features. The authors introduce Contrastive Representations for Temporal Reasoning (CRTR), using negative sampling to remove these features and improve temporal reasoning. CRTR excels on complex temporal tasks like Sokoban and Rubik's Cube, solving the latter faster than BestFS (albeit with longer solutions). Remarkably, this is the first demonstration of efficiently solving arbitrary Rubik's Cube states using only learned representations, eliminating the need for hand-crafted search heuristics.

AI Inference Costs: Not as Expensive as You Think

This article challenges the narrative that AI inference is prohibitively expensive and unsustainable. By calculating the costs of running AI inference on H100 GPUs, the author demonstrates that input processing is incredibly cheap (fractions of a cent per million tokens), while output generation is significantly more expensive (dollars per million tokens). This cost asymmetry explains the profitability of some applications (like coding assistants) and the high cost of others (like video generation). The author argues that this cost disparity is often overlooked, leading to an overestimation of AI inference costs, which may benefit incumbents and stifle competition and innovation.
