scottcha — Thu, 23 Jul 2026 14:21:30 +0000

We use vllm as it generally has the best ecosystem support. Parameters are largely dependent on what type of requests you are serving (concurrency, input/output ratios, cached hit patterns). We've never had a limitation at the tokenizer step. Limitations at peak tend to manifest more on slower time in vllm doing prefill or decode though we actively try and minimize this.

I run an AI platform and we need to tokenize fast and early to make a lot of decisions on the subsequent steps (things like routing, rate limiting and such). Its really important to do this efficiently even though its not a large % of total end to end time for the request.

Hi, I'm co-founder of Neuralwatt. While there aren't other providers selling by energy we also produce the same tokens stats you get at others (input, output, cached) and you can compare using those. The CO2 number is really just multiplying the energy by the CO2-intensity at the time/place we served the request. So everything is actually measured and can be derived externally.

The main observation when you compare to token prices our input/cached energy is much lower than the equivalent token prices while the output energy is generally higher. One of the reasons this is a bit cheaper, especially for agentic systems, is that in an fully built/cached session your input & cached to output ratio is really massive input to very small output (multiple orders of magnitude usually). The other thing we do is we actively work to optimize the system around tokens/joule with the goal of making the most energy-optimal system.

Happy to answer any other questions.

They do have a growing amount of Scope 1 emissions (emissions from their on site sources) which originally was primarily on site diesel but due to grid interconnect delays have been growing number of on site gas turbines.

This certainly wouldn’t be necessary with adequate generation and transmission capacity.

New comment by scottcha in "GLM 5.2 beats Claude in our benchmarks"

scottcha — Mon, 29 Jun 2026 15:36:47 +0000

Thanks for the feedback! Our primary focus is charging by energy, for token pricing we really just try to be close to the market. That being said I'll take a look at our token pricing to see if we need an update there https://portal.neuralwatt.com/energy-pricing Generally our users get much lower cost on energy than token pricing though on a typical request with a high prefix cache hit the input, cached costs is very small and the output energy cost is higher.

We definitely don't have any intention to obfuscate and in fact we actually try and provide more data than any other provider out there about both an individual request, as well as the fleet behavior. Since we tend to focus directly on our energy pricing and optimizing that the issue is likely where the ROI lies on energy optimization versus token optimization (totally correlated but we have other levers to reduce energy while keeping token counts the same).

Hi I'm the CTO of neuralwatt, would love to hear your feedback on what your experience was. Feel free to email me scott@neuralwatt.com. Also for GLM5.2 we run the FP8 quantization at 1M context which is a common deployment target.

Yes way better. We host both and while qwen3.6 is over 100tps we usually can do glm around that too.

scottcha — Fri, 12 Jun 2026 12:12:55 +0000

I use glm5.1 plus pi with a few customized skills and am very happy with it. I hadn’t touched my Claude 5x plan for a couple of weeks but opened it back up in Claude code when fable was released and did a few tasks and still was happy to return to glm/pi.

I use claude code and pi.dev side by side most days and i'm mostly choosing pi for most work in last couple of weeks.

scottcha — Sat, 04 Apr 2026 19:16:47 +0000

Pretty cool idea, but whats the stack behind this? As 15-25 tok/s seems a bit low as expected SoA for most providers is around 60 tok/s and quality of life dramatically improves above that.

I think there was a clarification posted on Reddit that said Claude Agents SDK didn't apply for now.

I use OpenCode and have just started using Nanoclaw with ClaudeCode (my coworker has a post coming on this) and sometimes ClaudeCode with Claude Code Router. I do a range of small to complex work with these but I also do drop back in to Claude Opus for some really complex things where I want it to be more autonomous.

Mine are pretty unique since we optimize the energy for and run an inference service api so forces me to dogfood alot of different options.

Yes GLM5 and KimiK2.5 are pretty close replacements for sonnet.

New comment by scottcha in "Qwen3.6-Plus: Towards real world agents"

scottcha — Thu, 02 Apr 2026 15:57:30 +0000

I switch between Claude Code (Opus/Sonnet) and Qwen (OpenCode, OpenClaw) multiple times throughout the day and Qwen 3.5 is really nice. I do also use KimiK2.5 and GLM5 pretty often too and I'm starting to get a sense that the agent tool is becoming a little more important than the model with these level of models. As long as tool calling and prompt quality is all configured correctly by the provider.

We offer multiple SOA models at https://portal.neuralwatt.com at very generous pricing since we have options to bill per kWh instead of per token. Recipes for your favorite tools here: https://github.com/neuralwatt/neuralwatt-tools

scottcha — Mon, 09 Mar 2026 18:59:38 +0000

I actually built this analysis while I worked at Microsoft so I 100% agree. Doing the work at the platform level is the way to go and you can actually make a significant impact with this kind of approach. The other value of this that's not obvious is that doing it client side ends up touching all the grids/generators in the world outside of the market based accounting that tends to drive the datacenter carbon impact analysis.

There have been a few questions about the state of Show HN lately. Was actually interested in this post but I see all the OPs responses to questions are Dead? I do see its a new account but I don't really see anything egregious or against policy for these.

New comment by scottcha in "Electricity use of AI coding agents"

scottcha — Tue, 20 Jan 2026 23:27:46 +0000

That is a pretty good article although the one factor not mentioned that we see that has a huge impact on energy is batch size but that would be hard to estimate with the data he has.

We've only launched to friends and family but I'll share this here since its relevant: we have a service which actually optimizes and measures the energy of your AI use: https://portal.neuralwatt.com if you want to check it out. We also have a tools repo we put together that shows some demonstrations of surfacing energy metadata in to your tools: https://github.com/neuralwatt/neuralwatt-tools/

Our underlying technology is really about OS level energy optimization and datacenter grid flexibility so if you are on the pay by KWHr plan you get additional value as we continue to roll new optimizations out.

DM me with your email and I'd be happy to add some additional credits to you.
