a16z "Rack Spread" charts: average token prices are down 67% since May while token spend is up 122%-160%, as GPU rental prices climb

a16z's Charts of the Week for Oct 30 (by Moses Sternstein) looks at the "Rack Spread": GPU rental prices are rising while token prices fall. The official a16z X account summed it up on Oct 31: since May, average token prices are down 67% and token spend is up more than 120%. By the article's napkin math, Ramp data gives roughly 122%, and Ornn's blended price multiplied by OpenRouter volume gives roughly 160%. A separate post says that since mid-July B300 rentals are up 106%, B200 up 66% and H100 up 17%. a16z also stresses that these indexes come from small, biased samples and do not show true total demand.

a16z "Rack Spread" charts: average token prices are down 67% since May while token spend is up 122%-160%, as GPU rental prices climb

Key Takeaways

  • Prices and spend: since May, average token prices are down 67% and token spend is up more than 120% (a16z post on X, a16z figures)
  • Two napkin estimates: Ramp token-spend data shows about +122%; Ornn blended price times OpenRouter volume shows about +160% (Charts of the Week, described by the author as napkin math, not a rigorous method)
  • GPU rentals since mid-July: B300 +106%, B200 +66%, H100 +17%, while average token prices fell 58% (a16z post)
  • AI spend per employee: an Atlanta Fed survey puts the mean above $1,000, while Ramp's median is $15.70 a month ($188 a year)
  • Reach: the two posts have about 371 and 492 likes and 38K and 96K views (as of 18:15 SGT)

vLLM Narrows Gap with DeepInfer to 6% on NVIDIA GB200, Reaching 1M Tokens/s per GPU on GB300

Hours after DeepSeek open-sourced DeepInfer, the vLLM project team released official benchmark parity data serving DeepSeek-V4.1-Flash. Utilizing DeepSeek's identical decoding setup (131K context window, nextn=3 speculative decoding), vLLM closed its throughput performance delta to within 6% of DeepInfer across batch sizes 8 through 256 on NVIDIA GB200 systems. On GB300 hardware, vLLM attained up to 1,000,000 tokens/second per GPU and 826 tokens/second per user, generating $38.96 in hourly GPU revenue at DeepSeek off-peak rates. vLLM simultaneously shipped day-0 runtime support for FastH3-Omni and Spark-X2.6-4B.

Eagle releases EAGLE-4, a speculative-decoding drafter that adapts to batch size and hardware; it reports 961.6 tok/s on Qwen3.8-27B for a single request

On Oct 20, inference company Eagle released EAGLE-4, the fourth generation of the EAGLE speculative-decoding family. One drafter resizes its speculative tree for the batch size, hardware and workload while keeping the target model's output distribution. Eagle reports 961.6 tokens/s for one request on Qwen3.8-27B with 4x B300. The code ships as eagle-harness v0.1.0 with plugins for SGLang, vLLM and an experimental TokenSpeed backend. Many reposts call it open source, but the official license is source-available, not OSI open source.

Eagle releases EAGLE-4, a speculative-decoding drafter that adapts to batch size and hardware; it reports 961.6 tok/s on Qwen3.8-27B for a single request

Key Takeaways

  • Vendor figure: 961.6 tokens/s on Qwen3.8-27B with TokenSpeed, BF16, 4x B300, TP4, one request, T=0 (paper Figure 1(a))
  • Repo measurements: vLLM on 4x B300 goes from 241.6 to 722.8 tok/s at concurrency 1 (2.99x) and 1.70x at concurrency 8; SGLang gets 1.91x at concurrency 8 and 1.35x at 64
  • AMD numbers too: SGLang on one MI355X gets 2.07x at concurrency 8 and 1.56x at 32 (ROCm 7.2)
  • Design: sliding-window draft layer, low-rank candidate head and append-only draft cache; the harness calibrates verify latency offline and grows the tree while gain per cost stays high
  • License: Eagle 4 Source-Available; free for noncommercial use, commercial use only under $20M trailing 12-month revenue and outside competing offerings

NVIDIA open-sources Flora, the robotics data engine behind GR00T: three models that caption and score robot video at roughly 1/125 the cost of GPT-6 Astra

On Oct 20, NVIDIA's GEAR lab (Jim Fan's team) open-sourced Flora, a model suite that turns human and robot manipulation video into timestamped action captions, process rewards, outcome rewards and rubric scores. It includes Flora-Captioner 27B and Flora-Rewarder 27B (both on Qwen3.5-27B) and Flora-TempSeg 9B (a LoRA on Qwen3.5-9B), with weights on Hugging Face under an NVIDIA non-commercial license. NVIDIA says it is the in-house data engine used to train GR00T, labeling 200,000 hours of video a day on 512 GB300s, matching GPT-6 Astra on annotation quality at roughly 125x lower cost.

NVIDIA open-sources Flora, the robotics data engine behind GR00T: three models that caption and score robot video at roughly 1/125 the cost of GPT-6 Astra

Key Takeaways

  • Three models: TempSeg 9B segments actions, Captioner 27B writes one instruction per segment, and Rewarder 27B outputs dense process rewards and an episode success score
  • Cost (NVIDIA estimate): about $0.72 per hour of source video on eight GB300s at $10 per GPU-hour, versus about $88.49 for GPT-6 Astra at maximum effort, a 122-125x gap
  • Quality (NVIDIA 50-episode internal eval): 57.1% for Flora versus 53.7% for GPT-6 Astra; failure recall on DenseRewardBench is 53.3% while frontier API models mostly score under 1%
  • Scale: NVIDIA says Flora labels 200,000 hours of video a day on 512 GB300s to train GR00T-2
  • License: NVIDIA OneWay Noncommercial, research only, with commercial and production use explicitly unsupported

Meta details Prometheus, the gigawatt-scale supercluster that trained Muse Wonder: 85%+ pretraining goodput, 90%+ for RL, scaling toward ~1M GPUs

Meta's engineering blog on October 19 gave the first detailed look at Prometheus, the New Albany, Ohio supercluster that trained the Muse family, including Muse Wonder. Phase one is complete with hundreds of thousands of GPUs, and the full build targets about 1 million. Muse Wonder training reached more than 85% goodput in pretraining and more than 90% in reinforcement learning, with a mean time between interruptions of about 47K GPU hours, since raised above 54K by firmware fixes. It runs GB200 NVL72 and GB300 NVL72 platforms, with Vera Rubin NVL72 arriving soon.

Meta details Prometheus, the gigawatt-scale supercluster that trained Muse Wonder: 85%+ pretraining goodput, 90%+ for RL, scaling toward ~1M GPUs

Key Takeaways

  • Scale: phase one trained the Muse family; it has hundreds of thousands of GPUs today, targets about 1 million, and runs across buildings as a single machine.
  • Reliability: Muse Wonder hit 85%+ pretraining goodput and 90%+ for RL; MTBI was about 47K GPU hours and is now above 54K.
  • Interruptions: a mid-2025 peak of nearly 1,000 events per 8K GPUs per day was cut by 99% over a year of engineering.
  • Sparing: each NVL72 rack runs a 64-GPU slice with 8 in-rack spares, plus about 2% spare racks; a 32,768-GPU job needs 523 racks or 37,656 GPUs, about 13% extra.
  • Network: each building fabric links up to 20,736 GPUs, and the aggregation network spans 2 km to over 100 km.

When Remote KV Cache Is Slower Than GPU Recompute: Sharded LMCache Cuts p99 from 83.32s to 0.67s on 8xB300, While Baidu VHA Halves KV Cache and Beats MLA

Addressing KV cache bottlenecks in long-context LLM serving, a new production study on 8xB300 nodes serving GLM-5.3 (arXiv:2610.21500) reveals that unsharded remote KV caches inflate hit-heavy p99 TTFT to 83.32s, and resolves it via rank-sharded asynchronous LMCache loading—boosting GET bandwidth 6.3x to 10.76 GB/s and slashing p99 to 0.67s (+34% throughput). Meanwhile, Baidu PaddlePaddle open-sources Virtual Head Attention (VHA, arXiv:2610.17959), folding linear Q-Premix and Postmix into standard GQA-2 weights at inference to halve KV cache while beating MLA (+0.70%) and GQA-4 (+2.60%) on a 30B-A3B MoE and lifting 8K-128K RULER from 73.0 to 84.4.

When Remote KV Cache Is Slower Than GPU Recompute: Sharded LMCache Cuts p99 from 83.32s to 0.67s on 8xB300, While Baidu VHA Halves KV Cache and Beats MLA

Key Takeaways

  • On 8xB300 nodes serving GLM-5.3 with PCP8, sharding LMCache across ranks and adding async loading boosts GET bandwidth 6.3x to 10.76 GB/s, cutting hit-heavy p99 TTFT from 83.32s to 0.67s (+34% throughput)
  • Baidu's Virtual Head Attention (VHA) folds linear Q-Premix and low-rank Postmix directly into W_Q and W_O at inference, reducing to a zero-overhead GQA-2 architecture with half to a quarter of the KV cache
  • On a 500B-token 30B-A3B MoE, VHA outperforms both MLA (+0.70%) and GQA-4 (+2.60%), and boosts 8K-128K RULER on a 10B-A1B MoE from 73.0 (GQA-4) to 84.4 using only 2 KV heads
