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.

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

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.

New comment by scottcha in "Cerebras launches Qwen3-235B, achieving 1.5k tokens per second"

scottcha — Wed, 23 Jul 2025 12:26:46 +0000

I’ve asked that question on linked in to the Cerebras team a couple times and haven’t ever received a response. There is system max tdp values posted online but I’m not sure you can assume the system is running in max tdp for these queries. If it is the numbers are quite high (I just tried to find the number but couldn’t find it but I had it in my notes as 23kw).

If someone from Cerebras is reading this feel free to dm me as optimizing this power is what we do.

Turns out there is multiple publications associating tachycardia and other heart symptoms with long covid. https://pmc.ncbi.nlm.nih.gov/articles/PMC8356730/

scottcha — Wed, 11 Jun 2025 17:47:48 +0000

Maybe I’m a statistical anomaly or maybe I just don’t know the baseline occurrence rate for this stuff but I have 3 close acquaintances two of which are this persons age or younger with similar symptoms (tachycardia, though to a lesser degree) going on. Is there data on the incidence rates for this stuff and has it been increasing since 2021?

The are many great things about Aurora, here are a few as I've been using it since it came out. 1. Its open source & open weights and free to use non-commercially. 2. Its configurable to easily fit on my local gpu for development purposes. 3. I've also gotten great engagement from the repo owners.

Yeah, that was my first thought. I actually wrote a blog post a few weeks ago modeling the point at which agent recursion really gets out of control. https://www.neuralwatt.com/blog/agent-bedlam-a-future-of-end...

Shameless plug . . . I run a startup who is working to help this https://neuralwatt.com We are starting with an os level (as in no model changes/no developer changes required) component which uses RL to run AI with a ~25% energy efficiency improvement w/out sacrificing UX. Feel free to dm me if you are interested in chatting either about problems you face with energy and ai or if you'd like to learn more.
