I keep telling people that we are living in the golden age of AI - like the first year or two of google. It is all down hill as these companies push for profit and lock-in.

Yes. Grab those open-weight models while you still can.

You mean like it's impossible to download a movie because it's illegal, it's going to be impossible to download open-weight models because it's going to be made illegal?

So for the same definition of "impossible", it's going to be "impossible" to download open-weight models?

Exactly why everyone needs to be hyper-focused on ensuring that the open-source ecosystem is healthy and that we don't let them shut that down.

> on ensuring that the open-source ecosystem There are no open source models. Only open weights . No one is giving you the source (training data). And yeah, no one is giving you the compute to train the models.

Olmo is one truly open source model. https://allenai.org/blog/olmo3

Well that's a horrifying thought. Thanks, I hate it.

Maybe agents won’t need to be sold to by CEOs jumping around on stage like pet monkeys. Could be an improvement.

This is undoubtedly true. Agents are extremely analytical and trained to be objective - far more so than humans. They are not driven by emotion. If you have good stuff and you make it extremely clear to everyone through your documentation, this is more likely to be persuasive to agents than to humans.

I for one would prefer a future in which the nuances of a good product can shine through without layers of bullshit.

For some reason Claude Code keeps using awk, sed, and even Python to do basic file editing. Anyone know why that changed with the 5 series?

These file edits are faster and easier for the model to do than "regular" edits. The model is told to use them when auto mode is enabled.

The problem is when you go from plan to auto to anything but auto, that preference sticks.

There is an option to opt-out: https://github.com/anthropics/claude-code/issues/88041#issue...

This won't save you from it chaining 500 bash commands with git push --force somewhere in the middle.

how does one do that from their comfy chair?

Support vendor agnostic tools offering agent integrations through the likes of Agent Client Protocol https://agentclientprotocol.com

ps. I built Emacs integration through ACP https://github.com/xenodium/agent-shell

I don't think it'll become impossible or even illegal, but better safe than sorry.

local models will be powerful enough, can't say the same about local search engines 20y ago

Oh and don't forget: it keeps chaining a bazillion commands together so any whitelisted commands still need approval because they're nested in such a convoluted way.

I have a hook that auto-denies when it sees 'python -c "', ' awk ', ' sed ', and '&&'
