Re:Integer multiplication below n log n on Tuesday October 06, 2026 @08:15PM (#49986103)
It's 50 pages and cites this other paper in the same repo:

OpenAI. An explicit power saving for the exact discrete Fourier transform.

Here's a random excerpt:

8.3 The middle transform and the final permutation The factor QFt in (35) can be computed from a cyclic convolution and two pointwise phase multiplications. The chirp identity below performs the frequency change in Q without applying Q as a separate permutation of the array. The second identity shows how the retained source permutation R cancels when computing a convolution. Here ∗ denotes cyclic convolution on the product of the coordinate groups and a dot denotes coordinatewise multiplication.

Re:Upwork unable to payout contracts for over 24h on Thursday May 14, 2026 @04:48PM (#48141023)
What are you all using instead of Upwork?
For compression and long-running agents, may I suggest https://memtree.dev. We offer a simple API that compresses messages asynchronously for instant responses and small context leading to much higher quality generations. We're about to release a dashboard that will show you what each compressed request looked like, the token distribution between system, memory, and tool messages, along with memory retrievals, etc... Is this the type of thing that you're looking for?
Re:GPT-4.1 in the API on Monday April 14, 2025 @10:39PM (#43688506)
For code it's actually quite good so far IME. Not quite as good as Gemini 2.5 Pro but much faster. I've integrated it into polychat.co if you want to try it out and compare with other models. I usually ask 2 to 5 models the same question there to reduce the model overload anxiety.
Re:My Response to Superintelligence Strategy on Monday April 07, 2025 @05:48PM (#43616311)
I discuss how the automation wave is already starting with white-collar job openings at a 12 year low in the U.S. I also talk about how we cannot simply count on taxing AI to support automated workers, as countries that don't tax will outcompete those who do. We therefore need international cooperation, based in MAIM, from the original Superintelligence Strategy paper.

I also discuss how bioweapons cannot be avoided via restricting open weight models as originally suggested in Dan's paper. Rather we need to heavily invest in bioweapon defense, and in particular use AI for wastewater monitoring and accelerating metagenomics (detangling mixed DNA).

I've added a "Thinking...." which sends server side events to keep the cxn open. Would love to hear if o1 models now work for anyone who they were broken for.
Open WebUI does offer an API, but I have it disabled for PolyChat.
One tradeoff of bringing your own API keys is that as you add more model providers, you get more billing accounts to deal with. Chorus also doesn't have an incentive to efficiently use your tokens. We save 67% on Anthropic token costs using Claude Caching. We also use cheaper "task models" for conversation titles, tagging, and parts of the RAG pipeline which all drastically cuts token costs.

For local models I highly recommend https://github.com/crizCraig/open-webui

They do the side by side thing that Chorus does and you can serve it to anywhere including your phone.

So it looks like some folks are getting errors with the non-streaming models, i.e. the o1 models. I think their long running cxns with zero packets may cause some networks to drop the requests. Will look into a hearbeat/keepalive on those.
It's not unlimited free unfortunately. After some free use, we provide monthly usage-tier plans. But there are no rate limits like other providers as you can move up to the next usage-tier.
Background chats are new in v5 of Open WebUI, so you can use it too. Overview has been there also, but it's kind hidden in the hamburger menu.

The upgrade/logout issue you're facing is likely due to not setting WEBUI_SECRET_KEY outside of your docker container. This causes all previous cookies to be unreadable as a new key will get generated by start.sh and won't decrypt the old cookies.

Cool! I should say most of PolyChat is open source at https://github.com/open-webui - just the combo models and payment are closed source right now. Open to arguments on making PolyChat fully open source as well!
Thanks! I definitely recommend launching quickly and iterating. "Pessimists sound smart. Optimists make money."

edit: I should add, I'm making only $30/mo in subs, but I just launched so we'll see!

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more

https://polychat.co

Hello HN! I was fed up switching between multiple UIs to ask GPT, Claude, etc… the same question and comparing the answers. So I built a way to ask multiple models the same question efficiently by having the LLM compare the responses and only show you new and valuable information from the 2nd model. This way you still get a fast response as normal from the 1st model, but also get any added...

Wow, this is awesome! Thanks for building. I didn't realize there was a protocol for streaming while rendering, though I noticed sumo.ai doing something similar for audio. Gemini with grounding is new to me also, very nice!
Another great session of George and John recording Oh My Love [1] shows what I think of as embracing rough but promising ideas along with balanities like tuning guitars, learning chords, etc... The Beatles engaged in this process much more than most musicians, despite it meaning most the stuff they played sounds relatively bad compared to playing tunes they'd practiced a bunch before. Is this due to work ethic or some love of creation? Idk, but it is fascinating to see the sausage get made.

Re:OpenAI: Introducing SuperAlignment on Wednesday July 05, 2023 @02:44PM (#36605153)
Allocating 20% to safety would not be enough if safety and capability aren't aligned. I.e. without saying Bostrom's orthogonality thesis is mostly wrong. However, I believe they may be sufficiently aligned in the long term for 20% to work [1]. The biggest threat imo is that more resources are devoted to AIs with military or monetary-based objectives that are focused on shorter-term capability and power. In this case, capability and safety are not aligned and we race to the bottom. Hopefully global coordination and this effort to achieve superalignment in four years will avoid that.

Re:Box Breathing Techniques and Benefits on Sunday November 13, 2022 @03:46PM (#33587167)
The nice thing about box breathing is that, unlike pursed lips for example, you can do it without anyone noticing, by quietly breathing through your nose. So if you're in a stressful meeting, you can calm yourself without anyone noticing :)
Re:Half of Americans anticipate a U.S. civil war soon on Wednesday July 20, 2022 @05:10PM (#32172366)
Turchin's political stability indicator predicts this due to rising economic inequality, overproduction of grads with advanced degrees, and exploding public debt [0][1].

However, civil wars usually occur in poorer countries [1][2]. Also the proportion of the world in civil war is 1% and falling exponentially [2].

Finally, Metaculus gives a 5% chance of US civil war before 2031, where a recent July bump is discussed in the comments (Roe, Jan 6) [3].

Re:To be energy-efficient, brains predict their perceptions on Wednesday November 17, 2021 @12:26PM (#29255957)
Prediction machines, yet critically, taking actions that pursue states which we are not quite able to predict. https://reader.elsevier.com/reader/sd/pii/S0896627315007679?...
Trillion parameter networks are mentioned a few times, but Tesla is deploying much smaller networks than that (like tens of millions IMU). Trillion param networks are mostly transformers like GPT-3 (actually 175B) etc... that are particularly heavy vs Conv as they have no weight sharing. Tesla is definitely starting to use transformers though, e.g. for camera fusion and evidenced by their focus on matrix multiply in dojo asic's vs the conv asics they have in the on-vehicle chips.
