    If I followed the links correctly this benchmark was made on a 16xH200. At current prices I&#x27;d assume that is a system price of around $750,000.<p>The year has 86400*365 = 31536000 seconds. Thus 63072000000 tokens can be generated. As pricing is usually given per 1M tokens generated, this is 63072 such packages.<p>Now lets write off the investment over 3 years, 250,000&#x2F;63072 = 3.96. So almost $4 per 1M tokens generated with prompt processing included.<p>Model was a Deepseek 671B 32B MoE.<p>Looks to me that $20 for a month of coding is not very sustainable - let&#x27;s enjoy the party while VCs are financing it! And keep an eye on your consumption...<p>Electricity costs seem negligable with ~$10,000 per year at 10cts per kWh but overall cost would be ~10% higher if electricity is more like 30cts like it is in Europe.<p>Edit: like it is pointed out by other commenters it is 2200t&#x2F;s per single GPU thus the result needs to be divided by 16: $4&#x2F;16 = $0.25. This actually somewhat matches the deepseek API pricing.

      How did you arrive to $10,000 electricity costs figure?<p>8xH200 enclosed in DGX H200 system power draw is ~14kW in its peak (CTS) configuration&#x2F;utilization. Over one year, and assuming maximum utilization, this is 123,480 kWh per single DGX H200 unit. We need 2x such units for 16xH200 system configuration under subject so it&#x27;s 246,960 kWh&#x2F;year. This is ~$25,000 at 10cts per kWh and ~$74,000 at 30cts per kWh. At ~1,110,000 1M batches this gives us: (1) ~$0.02 - $0.07 per 1M of energy cost and (2) ~$0.25 per 1M assuming the same HW depreciation rate. In total, this is ~$0.3 per 1M tokens.<p>Seems sustainable?
      • dust422 hours ago
        I used 700W per H200 = 11.2 per 16 GPUs. I didn&#x27;t include CPU and rest of the rack. So yours is a better approximation.<p>One has to keep in mind that the benchmark that was done is synthetic. This makes sense because it makes it reproducible but real world usage may differ - i.e. by the amount of context and the number of concurrent users. Also there are use cases where smaller models or smaller quants will do.<p>The key take away for me for this type of back of the envelope calculation is to get a good idea where we stand long term, i.e. when VC money stops subsidizing.<p>So for me $0.3 per 1M tokens for a decent model looks pretty good too. Seeing that OpenAI API charges $21 per 1M tokens input and $168 output for GPT-5.2 pro I was wondering what the real sustainable pricing is.
    • yorwba6 hours ago
      It&#x27;s 2.2k tokens per second and GPU, so you have to multiply the token output by 16 and the price per million tokens works out to 22.5 cents.
      • aurareturn1 hour ago
        I think they&#x27;re also running this at 16 bit quant. If they lower it to 8bit, they might double their output which might come out to be 11 cents per million tokens.<p>Now take into account that modern LLMs tend to use 4bit inference, and Blackwell is significantly more optimized for 4 bit, we can see much less than 11 cents. Maybe a speed up of 5x if using 4bit and Blackwell vs H100 and 8 bit?<p>So we&#x27;re looking at potentially 2.2 cents per million tokens.

      APIs are usually <i>very</i> profitable. As for subscriptions, it would depend on how many tokens average subscriber uses per month. Do we have some source of info on this?<p>Some notes:<p>- # Input tokens &amp; # output tokens per request matters a lot.<p>- KV Cache hit rate matters a lot.<p>- vLLM is not the necessarily most efficient engine.<p>- You are looking at API cost for DeepSeek V3.2, which is much cheaper than DeepSeek R1 &#x2F; V3 &#x2F; V3.1. DeepSeek V3.2 is different architecture (sparse attention) that is much more efficient. DeepSeek V3 cheapest option (fp8) tends to be ~$1&#x2F;mil output tokens while R1 tends to be ~$2.5&#x2F;mil (note that for example Together AI charges whopping $7&#x2F;mil output tokens for R1!)<p>As for the cost: You can also get H200s for ~ $1.6&#x2F;hr and H100s for ~ $1.2&#x2F;hr. That somewhat simplifies the calculations :)<p>Ignoring the caveats and assuming H200s, with their setup you will:<p>- Process 403200000 input tokens.<p>- Generate 126720000 output tokens.<p>- Spend $25.6.<p>- On Together with DS R1 it would cost you $3 * 403.2 + $7 * 126.7 = ~$2096. Together does not even offer discount for KV cache hits (what a joke :)).<p>- On NovitaAI with DS R1 it would cost you $0.7 * 403.2 + $2.5 * 126.7 = ~$600 (with perfect cache hit rate, which gives 50% discount on input tokens here, it would be ~$458).

      I think you missed something here - its 2.2k tokens _per_ GPU<p>So if you work that through its $0.225 per 1M output tokens.

      &gt; more like 30cts like it is in Europe<p>Nope - i live in one of the most expensive areas, and even the residential price has averaged 18c&#x2F;kWh delivered including taxes. Businesses get a lower basic rate and also don&#x27;t pay the VAT, so it works out around 13c&#x2F;kWh for them.<p><a href="https:&#x2F;&#x2F;data.nordpoolgroup.com&#x2F;auction&#x2F;day-ahead&#x2F;prices?deliveryDate=2025-01-14&amp;currency=EUR&amp;aggregation=DailyAggregate&amp;deliveryAreas=EE,LT,LV,AT,BE,FR,GER,NL,PL,DK1,DK2,FI,NO1,NO2,NO3,NO4,NO5,SE1,SE2,SE3,SE4,BG,TEL,SYS" rel="nofollow">https:&#x2F;&#x2F;data.nordpoolgroup.com&#x2F;auction&#x2F;day-ahead&#x2F;prices?deli...</a>

        That&#x27;s excluding tax, net prices around 0.20-0.30 EUR &#x2F; Kwh we common.
        • supermatt5 hours ago
          I updated my comment to include my personal delivered rate including VAT - also note that businesses (like a data center) don&#x27;t pay the VAT and have substantially reduced delivery fees at high voltage
          • ffsm84 hours ago
            Then you&#x27;re living in one of the cheapest areas for electricity prices in Europe, the opposite of what you said.<p><a href="https:&#x2F;&#x2F;ec.europa.eu&#x2F;eurostat&#x2F;statistics-explained&#x2F;index.php?title=Electricity_price_statistics" rel="nofollow">https:&#x2F;&#x2F;ec.europa.eu&#x2F;eurostat&#x2F;statistics-explained&#x2F;index.php...</a><p>Scroll a little down and you see a breakdown by country<p>E.g.<p><a href="https:&#x2F;&#x2F;ec.europa.eu&#x2F;eurostat&#x2F;statistics-explained&#x2F;index.php?title=File:Electricity-price-pps-s1-2025.png" rel="nofollow">https:&#x2F;&#x2F;ec.europa.eu&#x2F;eurostat&#x2F;statistics-explained&#x2F;index.php...</a>
            • supermatt3 hours ago
              I am in Lithuania, which has one of the highest wholesale energy prices in Europe (as per nord pool): <a href="https:&#x2F;&#x2F;data.nordpoolgroup.com&#x2F;auction&#x2F;day-ahead&#x2F;prices?deliveryDate=2025-01-14&amp;currency=EUR&amp;aggregation=YearlyAggregate&amp;deliveryAreas=LT,GER,NL,BG,UK" rel="nofollow">https:&#x2F;&#x2F;data.nordpoolgroup.com&#x2F;auction&#x2F;day-ahead&#x2F;prices?deli...</a><p>That it is not translating into a higher cost to the consumer (as evidenced on your link) is likely indicative of other costs being incurred by the “average” consumer in those countries with a higher domestic rate - like massive markup from users being tied into inflated contracts due to the 2022 shock where rates across Europe were more than double what they are now.<p>Also, these are residential prices - business prices are usually much lower (wholesale discounts, subsidies, no VAT, lower delivery charges).<p>As per my response to the initial comment - there is no way a datacentre in Europe is paying 30c&#x2F;kWh
              • menaerus3 hours ago
                Some countries also employ progressive electricity pricing such that higher energy consumption leads to elevated kWh rates incentivizing conservation. This is also not visible in the stats above. I also think that business kWh rates are actually higher than for the households in some instances.
                • supermatt2 hours ago
                  Yeah, strictly business vs residential isn’t a good comparison either really, as the lower transmission fees for medium (10kV+) and higher voltage are where a lot of the savings are - and obv a lot of business don’t use such power.

  • kingstnap12 hours ago
    Impressive performance work. It&#x27;s interesting that you still see these 40+% perf gains like this.<p>Makes you think that you will continue to see the costs for a fixed level of &quot;intelligence&quot; dropping.
    • davidhyde6 hours ago
      vLLM needs to perform similar operations to an operating system. If you write an operating system in Python you will have scope for many 40% improvements all over the place and in the end it won’t be Python anymore, at least under the hood it won’t be.
      • menaerus5 hours ago
        It&#x27;s not about the python at all. Optimization techniques are on a completely different level, on the level of the chip and&#x2F;or hw platform and finding ways to utilize them in a max manner by exploiting the intrinsic details about their limitations.
    • whoevercares11 hours ago
      Absolutely. LLM inference is still a greenfield — things like overlap scheduling and JIT CUDA kernels are very recent. We’re just getting started optimizing for modern LLM architectures, so cost&#x2F;perf will keep improving fast.
  • Palmik3 hours ago
    I wish there were more open benchmarks comparing different setups and different engines. There are so many knobs to tune (TP &#x2F; DP &#x2F; PP &#x2F; PD &#x2F; spec. decoding &#x2F; etc.) and while the optimal setup will be highly dependent on the model, the environment and the traffic, it&#x27;s likely some useful conclusions could be drawn.<p>It almost feels like in the past year there is some unwritten agreement between the 3 main open-source engines (vLLM, sglang, TRT-LLM) to not compare to each other directly :) They used to publish benchmarks comparing against each other quite regularly.
  • rbanffy5 hours ago
    Very impressive numbers - I&#x27;d expect 2K tok&#x2F;s on Cerebras hardware, not H200&#x27;s.
    • mzl4 hours ago
      I don&#x27;t think it would be economically viable to serve the full DeepSeek models on Cerebras hardware.

    Hey HN! I’m Seiji Eicher from Anyscale, one of the authors of this post :) Feel free to ask questions here.
    • aurareturn1 hour ago
      Are you using 16bit for inference? How many tokens&#x2F;second if you use 8bit?<p>Given that SOTA models now use 4bit inference, can you do an estimation for 4bit + Blackwell?
    • menaerus5 hours ago
      Do you use agentic AI yet for this type of optimization work or no?

    Now all we need is better support for AMD gpus, both CDNA and RDNA types
    • mappu10 hours ago
      ZLUDA implements CUDA on top of AMD ROCm - they are explicitly targetting vLLM as their PyTorch compatibility test: <a href="https:&#x2F;&#x2F;vosen.github.io&#x2F;ZLUDA&#x2F;blog&#x2F;zluda-update-q4-2025&#x2F;#pytorch-support-underway" rel="nofollow">https:&#x2F;&#x2F;vosen.github.io&#x2F;ZLUDA&#x2F;blog&#x2F;zluda-update-q4-2025&#x2F;#pyt...</a><p>(PyTorch does also support ROCm generally, it shows up as a CUDA device.)
      • ikari_pl7 hours ago
        I feel like these technologies are named by the Polish at the companies. &quot;CUDA&quot; means &quot;WONDERS&quot; and &quot;ZŁUDA&quot; would be an &quot;ILLUSION&quot;.
        • Gracana2 hours ago
          ZLUDA was definitely intentional: <a href="https:&#x2F;&#x2F;github.com&#x2F;vosen&#x2F;ZLUDA&#x2F;discussions&#x2F;192" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;vosen&#x2F;ZLUDA&#x2F;discussions&#x2F;192</a>
    • sofixa5 hours ago
      You can run vLLM with AMD GPUs supported by ROCm: <a href="https:&#x2F;&#x2F;rocm.docs.amd.com&#x2F;en&#x2F;latest&#x2F;how-to&#x2F;rocm-for-ai&#x2F;inference&#x2F;deploy-your-model.html" rel="nofollow">https:&#x2F;&#x2F;rocm.docs.amd.com&#x2F;en&#x2F;latest&#x2F;how-to&#x2F;rocm-for-ai&#x2F;infer...</a><p>However from experience with an AMD Strix Halo, a couple of caveats: it&#x27;s drastically slower than Ollama (tested over a few weeks, always using the official AMD vLLM nightly releases), and not all GPUs were supported for all models (but that has been fixed).
      • bildung3 hours ago
        vLLM ususally only plays out its strength when serving multiple users in parallel, in contrast to llama.cpp (Ollama is a wrapper around llama.cpp).<p>If you want more performance, you could try running llama.cpp directly or use the prebuilt lemonade nightlies.
        • sofixa1 hour ago
          But vLLM was half the t&#x2F;s of Ollama, so something was obviously not ok.

  • behnamoh7 hours ago
    I couldn&#x27;t care less, tbh. This speed is ridiculously high, to the point where tool calls, not inference, become the bottleneck.<p>Also, I&#x27;d rather run a large model at slower speeds than a smaller at insanely high speeds.
    • menaerus7 hours ago
      Well the thing is that the trajectory of people utilizing the models is only increasing so getting the most out of your HW becomes a particularly interesting optimization point for companies doing the inference at massive scale.
    • spiderfarmer7 hours ago
      You care enough to comment, so you could in fact have cared even less.<p>Also, the entire industry profits from the work that’s done at the bleeding edge. That’s the case in every industry.

      Have you considered parrallel processing? I always have 2-3 Cursor IDE open because I don&#x27;t like wait either.
      • bob10296 hours ago
        Parallel tool calls do not work for my scenario. I can&#x27;t ask a copy of my agent a question about something until a dependent call has resolved.<p>Tool use that changes the mode of the environment is a good example where you cannot go parallel. I&#x27;ve built a recursive agent that can run a Unity editor and I can&#x27;t just blindly run whatever it wants in parallel or combos like SwitchScene -&gt; GetSceneOverview won&#x27;t interleave correctly. You&#x27;ll wind up with 15 calls that loop over every scene and then you grab the overview from the last scene you switched to 15 times.<p>There are ways to hack around it a bit, but at some level the underlying narrative does need to be serialized or you&#x27;ll be wasting an incredible amount of resources.<p>Depth-first search doesn&#x27;t guarantee the best solution, but on average it&#x27;s guaranteed to find a solution faster than breadth-first search. It&#x27;s worth waiting for those dependent calls and going super deep if you want <i>some</i> reasonable answer quickly.
  • vessenes11 hours ago
    As a user of a lot of coding tokens I’m most interested in latency - these numbers are presumably for heavily batched workloads. I dearly wish Claude had a cerebras endpoint.<p>I’m sure I’d use more tokens because I’d get more revs, but I don’t think token usage would increase linearly with speed: I need time to think about what I want to and what’s happened or is proposed. But I feel like I would be able to stay in flow state if the responses were faster, and that’s super appealing.
