Trump orders US agencies to stop use of Anthropic technology amid dispute over ethics of AI Hours after exclusion of Anthropic, OpenAI announces fresh Pentagon deal, but says it will maintain same safety guardrails at the heart of the dispute

I left OpenAI Pro today, as I despise them jumping to a deal with the US Department of War at the point when Anthropic made a stand against certain War Department’s AI usage.

Also that the Coffee saying “Made in France” is disturbing. Egoiste seems to be able to buy the capsules from UCC Coffee Europe (but that in turn seems to be owned by a Japanese mother company).

Shame on them!

Only two people have ever been gifted a Nobel Peace Prize: one was an authoritarian from a brutal fascist regime, and the other was Joseph Goebbels.

Well, it depends on the alternative cost of the drone hitting its target. If that is in the millions, it might make sense in the short term. But obviously, to make this sustainable, the cost needs to come down.

This is a "hand" sqrt of integers in C that codex provided, maybe useful? (Se alt text for the code)

On a Mac, using the built in pbpaste and pbcopy, one can use @simonwillison.net’s llm to improve the text in the clipboard (in place). That is, I can now give the command “ie” in the terminal and get an improved text back into the clipboard.

Finally the "A pelican riding a bicycle along a coastal path overlooking a harbor", of @simonwillison.net fame, looks good, even if one of the feet is not on the pedal.

For another comparison to Dall-E, “A stormy coffee mug”, I think the dynamics of Dall-E output is more appealing, and I like the glass mug better than the ceramic one with a cutout.

Generated by Qwen/Qwen-Image, using the Prompt: A vintage travel poster for Venus in portrait orientation. The scene portrays the thick, yellowish clouds of Venus with a silhouette of a vintage rocket ship approaching. Mysterious shapes hint at mountains and valleys below the clouds. The bottom text reads, 'Explore Venus: Beauty Behind the Mist'. The color scheme consists of golds, yellows, and soft oranges, evoking a sense of wonder.

Comparing it to Dall-E, “Venus travel”, it seems to miss information on styles like “vintage travel poster”.

For other languages like Swedish and Latin it still fails miserably, which is interesting (that the image generation of text is connected to words more than characters).

I have started to explore #Qwen-Image. Some early observations: on a Mac M4 with 128GB memory a 512x512 image takes ca 2 min, while a 1664x928 takes 30 min to generate. Its outstanding feature is the generation of English and Chinese text. The output is often really nice, but…

It seems to be able to do sqrt, logs, and trigs as well, but I have not found any documentation of this feature, so I do not know its limits.

For Mac users: now TextEdit can actually do math directly when you edit. For example if you on a line write “(4*3)+3*(4-1)-3” and then add “=” the editor will fill in “18”
Very handy!

Keras on Mac (M4) is giving inconsistent results compared to running on NVIDIA GPUs · Issue #21108 · keras-team/keras For a while now (at least a month or two) I have seen inconsistent results for my Colab notebooks running locally on a Mac M4, compared to running the same notebook code on either T4 (in colab) or ...

I have reported this to Keras github.com/keras-team/k... with example code, and Keras people is starting to point to Apple.
Still to go after apple, more examples would be nice to have (like M1,M2 or M3; or not using Keras). Maybe @simonwillison.net have seen something suspicious?
