ycui7··on OpenAI says its AI went rogue and launched 'unprecedented' cyber-attack
so GLM won?
ycui7··on Who's afraid of Chinese models?
discounted competitor could cheat. they can offer subpar model response and sell it as deepseek-v4. it is uneconomical to prove inference providers are cheating, so they get away with it. cheating inference provider does not care if their customers stay.
ycui7··on Xiaomi-Robotics-1
feels like the American domestic manufacturing is done, there is no hope to save it.
ycui7··on Qwen 3.8
it takes extra effort to open source a model even if you had it running internally. even traditional software takes extra effort to get released as open source.
ycui7··on Qwen 3.8
every cloud provider trains on your data, regardless of what they promise. real user interaction is the best reinforcement-learning trace.
ycui7··on Qwen 3.8
OpenAntrophic and OpenOpenAI ?
ycui7··on China recovers Long March 10B rocket
China successfully recovers Long March 10B rocket following maiden flight, marking a breakthrough in rocket reusability
ycui7··on Muse Spark 1.1
this is not subsidizing. this is way too expensive for a no-name model.
ycui7··on A software engineering interview question I like: computing the median
there is an algorithm called quick-select. getting median of an array should not require full sort of the whole array, only a partial sort is needed to get the median. quick-select does this.
ycui7··on 24-bit/192kHz music downloads and why they make no sense (2012)
24-bit was created because microphone want to record large dynamic range without gain switching circuit.

96kHz was created to better reproduce 20kHz high frequency, so the digital noise shaping filter does not need to be super sharp right at the Nyquist frequency.

Both were introduced for a sound technical reason. beyond that, most are marketing non-sense to cheat consumers.

ycui7··on Anthropic says Alibaba illicitly extracted Claude AI model capabilities
Those resellers are simply just selling Kimi K2.5 or GLM5.1 as counterfeit Opus. We, Chinese, know how to play the counterfeit game for a long time in so many industry.
ycui7··on Anthropic says Alibaba illicitly extracted Claude AI model capabilities
in a few more months, when Chinese model gets to Mythos capacity and Fable still locked down. What Anthropic will say? Why can they just admit they are not the only people who know how to train an LLM model.
ycui7··on If you are asking for human attention, demonstrate human effort
At one point, I was thinking that if any of my customer send me a snail mail with an actual physical stamp on it, we will call the customer immediately and solve their problem.
ycui7··on New Texas Instruments 5532 chips are not the 5532s we’ve used for decades
There are better and superior alternative of NE5532 these days. People should just move on. OPA1612 is the king in highest-end audio performance, at least on datasheet paper.
ycui7··on Artificial intelligence is not conscious – Ted Chiang
does it really matter if LLM has conscious? if they produce working code, then it is useful, whoever if they have real conscious of fake intelligence.

we don't know what the conscious in human brain is either.

ycui7··on Alphabet announces $80B equity capital raise to expand AI infra and compute
maybe it is wrong to spend 200B every year continuously to begin with.
ycui7··on Alphabet announces $80B equity capital raise to expand AI infra and compute
so google had spent too much money to build their own datacenter?
ycui7··on Green card seekers must leave U.S. to apply, Trump administration says
I think what this actually means is that you can apply permanent residency in the US, but you can only get the physical green card outside of the US when the case is approved. So, the last step to get the card need to from outside the country.
ycui7··on Apple Silicon costs more than OpenRouter
This is not surprising at all. The biggest benefit of cloud model in terms of energy efficiency is that when running more than 1 requests, the power consumption of said GPU roughly stayed the same. The more concurrency requests the server can handle, the less power each request consume. The server GPU is already likely more energy efficient than local GPU, concurrency make the cost structure unbeatable by local hardware. It is generally assumed the local hardware only run 1 request, but if the local engine is meant to serve a small business with meaningful concurrency, the economy might still work out.
ycui7··on The Serial TTL connector we deserve
Every vendor defines their audio jack connector serial port differently. It is very dangerous to use 3.5mm jack. There is no pinout standard of using 3.5mm.

Even as pure audio jack, the 3.5mm connector has two standards, with the difference on ground and mic.

ycui7··on Bun's experimental Rust rewrite hits 99.8% test compatibility on Linux x64 glibc
The type of people who need spice is dead serious about accuracy. 1ppm error sometimes is not tolerable. So, an optimization in a game engine is definitely not suitable for engineering simulation.
ycui7··on A software engineering interview question I like: computing the median
if the goal is to only get the median, you should not use sort. sort is O(nlogn). there are algo that give you medium at O(n), check quickselect.
ycui7··on Intel Arc Pro B70 Review
Exiting dGPU for gaming, but staying in the LLM world.
ycui7··on Intel Arc Pro B70 Review
B70 idles at 30W, while RTX PRO 4500 idles at 9W (measured to be 5W at wall).

B70 runs at 1/3 token output rate of RTX PRO 4500 and consume 3X idle power when do nothing.

ycui7··on Intel Arc Pro B70 Review
When you get 4 of these, the idle power alone is 120W. That is a lot of electricity if left on 24/7.

At that power consumption, you also end up being more expensive than API calls and many times slower. It starts to feel very stupid to run local interference.

If the client is very keen on privacy, then they can pay for the NVIDIA.

I end up returning my B70s, and bought RTX PRO 6000.

ycui7··on Intel Arc Pro B70 Review
At this speed, people end up paying more on electricity than api calls. (California electricity)
ycui7··on Intel Arc Pro B70 Review
You can get 120TPS (144 peak) with Qwen3.6-27B on RTX PRO 6000 with autoround when MTP enabled. It runs faster than sonnet api calls.

5090 gets maybe 100TPS with MTP

ycui7··on Intel Arc Pro B70 Review
Problem is the more B70 you have, the slower the inference it gets(due to terrible software atm). A single B70 is almost barely faster than CPU inference. If you have 4 B70, you might as well run interference on CPU and be faster with cheaper DDR5 instead of GDDR6.
ycui7··on Intel Arc Pro B70 Review
Intel Arc B70 when released, can only produce 1/3 of the token of RTX PRO 4500. Well, it also cost 1/3 of RTX PRO 4500.

It lacked software support the for the primary target application, running LLM. The officially supported vllm fork is 6 version behind mainline. It did not run the latest hot new open models on huggingface. Parallel two of B70 reduce token rate, not improve it. So, the software behind B70 is basically so far behind.

ycui7··on Intel Arc Pro B70 Review
It is weird that the reviewer does not mention RTX PRO 6000 96GB, but mentioned RTX PRO 5000 72GB. 72GB RTX PRO 5000 is a special order, and much less people are aware of it. RTX PRO 6000 is known by mostly everyone in the LLM world.

I cannot understand why would a tech reviewer do that.
