It's more like, if it gets it right 99% of the time, that sounds incredible.

Until it's making 100k decisions a day and many are dependent on previous results.

So someone took a picture of the key at the live training session or something? What's the suspected cause?

Genuinely trying to understand what exactly the offering is.

Optionally turn locking off?

What does it mean to unlock when the device unlocks? I think every single one of my apps might have built this feature too.

All the weird stuff happening with anthropic / Claude aside- just talking about this post:

Looking at the table with February and April- I don't get it. What am I missing?

The cost and number of calls look pretty aligned on all rows

Depending on how I'm using the computer, I may definitely have deep marks after working laying down, but if I sit in a wood chair for a while it's the same thing- and my forearm is much tougher than behind my knee.

I suppose I would prefer it nice and rounded and soft on my wrist - but I don't feel like it's quite as extreme as this thread would have you believe lol

People keep saying this and idk what I'm doing wrong. Using q8_0 on all the latest and greatest local models and they just don't come close to sonnet.

I've tried different harnesses, building my own etc.

They are reasonably close to haiku? Maybe?

fwiw, other models seem to / are reported to struggle much more with using claude code compared with codex / opencode / pi etc.

that being said, there are other potential explanations

Definitely SDL2.

Author is currently building version 12 which will be using SDL3. But it's been in development for quite some time with no clear end date afaik.

Note to author: the WebGL has great zoom settings, but WebGPU has different ones that feel very low-sensitivity (at least on trackpad on macos)

Haven't had time to try yet, but heard from others that they needed to update both the main and runtime versions for things to work.

> OpenAI applies it automatically and charges 50% less for cache hits

This is incorrect. It's 90% cheaper.

What am I supposed to opt out of? The only setting in "Privacy" is "Suggestions matching public code" which is blocked and seems wholly unrelated to this.

Idk about "memory is cheap" but storage certainly is.

Whether you're talking about buying or renting in the cloud - RAM is 3 orders of magnitude more expensive

v2 was a static fill in the blank task instead of v3 which is interactive.

There's world state that you can change. Not just place pixel.

Here's v2:
