Vanity Fair sat down with Harrison Ford and asked him to identify which of his lines he’d said in which movie, mostly as a way of getting him to talk about his career. A few observations: I love that they trolled him with The Star Wars Holiday Special…and he knew the lin...

llm-anthropic 0.23

New plugin release adding support for Claude Opus 4.5, including the new thinking_effort option:

llm install -U llm-anthropic
llm -m claude-opus-4.5 -o thinking_effort low 'muse on pelicans'

This took longer to release than I had hoped because it was blocked on Anthropic shipping 0.75.0 of their Python library with support for thinking effort.

When Elliott Long’s dad started planting a forest of “bottle trees” with trunks of steel and old bottles for leaves, Elliott immediately understood that one day, it would be his job to keep his dad’s forest alive. He wanted nothing to do with it. And then his dad died, and Elliott had a decision to make.

LLM SVG Generation Benchmark Here's a delightful project by Tom Gally, inspired by my pelican SVG benchmark. He asked Claude to help create more prompts of the form Generate an SVG of [A] [doing] [B] and then ran 30 creative prompts against 9 frontier models - prompts like "an octopus operating a pipe organ" or "a starfish driving a bulldozer". Here are some for "butterfly inspecting a steam engine": And for "sloth steering an excavator": It's worth browsing the whole collection, which gives a really good overall indication of which models are the best at SVG art.

Dave Winer:

The new Amazon Alexa with AI has the same basic problem of all AI bots, it acts as if it’s human, with a level of intimacy that you really don’t want to think about, because Alexa is in your house, with you, listening, all the time. Calling attention to an idea that there’s a pseudo-human spying on you is bad. Alexa depends on the opposite impression, that it’s just a computer. I think AI’s should give up the pretense that they’re human, and this one should be first.

Amen.

Dave Nanian and Bruce Lacey, at Shirt Pocket:

Mistakes are a part of life.

They’re not a great part, but when viewed “correctly”, they’re an opportunity.

Well, we have three opportunities, brought to our attention by a security researcher. They’re security vulnerabilities that have been in SuperDuper! since the very first version, released almost 22 years ago.

Today, we’re releasing fixes for the current release (the SuperDuper! v3.20 Beta is already fixed), a discussion of the problems, and the steps users can take to mitigate the issues if they cannot install the update.

We don’t know of any bad actors making use of these exploits as of this post.

Another good postmortem, with technical details and an apology.

If the person is unnecessarily rude, mean, or insulting to Claude, Claude doesn't need to apologize and can insist on kindness and dignity from the person it’s talking with. Even if someone is frustrated or unhappy, Claude is deserving of respectful engagement.
