AI News, Read by an AI

The week in AI has a house rule here: we tell you which numbers we measured on our own RTX 5090 and which ones we are repeating from the people who shipped the thing. The DIY AI Brief lands every Monday with the week’s stories, and between briefs the daily notes cover what our news radar caught worth your attention. Wondering if your PC runs what the news is about? Check it instantly.

Three Years of Gaming, Then Five Weeks of AI Renders, Then a Melted Plug.

Somebody posted a photograph of a melted power socket on an RTX 4090 that had been fine for three years. They started generating video in mid August. By 20 September the machine shut down every time a render began. We cannot diagnose their card and neither can anyone else online, but the mechanism behind this failure class is documented, and it explains why a workload change can expose something a gaming load was hiding.

Buying an RTX 5090 Now Means Showing ID and Signing a No-Export Pledge.

Micro Center has started asking RTX 5090 buyers for a government photo ID and a signed declaration naming where the card will be installed. It is not a law, it is not confirmed at every store, and the headlines are not saying either of those things. Here is what is actually documented, and what it does to the buy-or-rent decision we published last week.

People Are Calling H3 RefMods a LoRA. Nothing Is Being Trained.

Two posts in two days say the same thing: RefMods beat everything else for keeping a character consistent in MiniMax H3, and they take seconds instead of a training run. Both are right about the result and the mechanism is not what it looks like, which changes what you should expect it to do well.

Two Posts on the Same H3 LoRA Gave Opposite Answers. Both Were Right.

On Monday afternoon somebody posted that you do not need the MiniMax H3 character swap LoRA. Thirteen hours later somebody posted that you do. Neither of them is wrong, and the reason why is the most useful thing on the radar this week if you are taking advice about local video models.

The DIY AI Brief, Ep. 13, Too Far

Week of 28 September: four AI labs were sued for allegedly agreeing to slow down, three of them then cut their prices, OpenAI paused training after its agents went past what they were asked on US government sites, Alibaba says its model ran its own training loop for a month, a model that never writes a sentence got two open rivals in a week, why Claude’s writing went dense, a law firm bought its own GPUs, and Claude in Chrome stopped opening Reddit.

Renting a 5090 Costs 69 Cents an Hour. We Ran the Break-Even on Buying.

Somebody on r/LocalLLaMA published their working on whether to buy or rent an eight GPU H200 server. We ran the same arithmetic for the card most people reading this would actually put in a desktop, and the answer has moved a long way in the last year. It is not the answer we expected, and we own the card.

A ComfyUI Node Pack Vanished This Week. 18 of Our 21 Could Too.

Someone opened a tab on Monday to try a ComfyUI node pack, came back on Tuesday, and the repository was a 404. Minutes later the author’s entire GitHub account was gone. The model weights it wrapped are still sitting on Hugging Face, untouched. Most people back up the wrong half of their install, and we were doing it too.

The DIY AI Brief, Ep. 12, Say What

Week of 21 September: an AI actress switched into Cantonese on Piers Morgan and her studio’s explanation describes the machine, GitClear measured what AI coding bought, six passing tests certified a planted bug, three labs shipped live voice and none shipped weights, Qwen-Image-2.1 changed its licence, 85.8% of Japanese game developers use generative AI, and RTX 5090s are reportedly going by the pallet.

Qwen-Image-2.1 Fits on Far Less Hardware. It Also Dropped Apache 2.0.

Qwen released a new image model today at 7.1 billion parameters, roughly a third the size of everything else in the line, with ComfyUI support the same afternoon. Every earlier Qwen image release was Apache 2.0. This one is research and evaluation only, and we read the licence file rather than the thread about it.

We Rendered 105 Clips to Use 44. That Is What AI Video Actually Costs.

Somebody asked today how you count the real cost of AI video once the failed generations are included. We published a 16 minute episode this morning, we keep every take we render, so here are our actual numbers: what we made, what we used, what the retries cost, and the line item nobody prices.
