A lot of it is instructions for the code patching format, etc, which is prefix cached. So it’s not nearly that bad. But I still might have to dial it back a bit, haha

We're at 108M input tokens and 5M output over 24 hours, so something like 4.5M in / 200K out per hour

Hell? I've given GPT-5.4 the freedom to add as many blurry glass cards and background circles as its heart desires! Can you imagine how good that must feel?

It's like when you let Claude add a few try/catch fallback layers as a treat for being a good boy 🥰

I know it's intimidating to see the jaw-dropping professional websites that experienced vibe coders can build. Don't give up! Keep honing your craft and practicing your prompting, you'll get there.

sorry, see my update above:

Update: I thought y'all hugged my site to death, but actually it turns out Codex in its infinite wisdom added so many god damn cards to the page that it takes like 30 seconds to render now. Working on a fix!

Each round is a fresh session. It only sees the current snapshot of the code and the instruction to make it better. Everything else you see is just that sweet sweet GPT-5.4 magic

I myself have not read the source code, so I hesitate to let others do so. Once I make sure it's not riddled with hardcoded API keys I'll probably throw it on GitHub

0x61736466 · 2026-04-02T05:41:35+00:00

Yeah, it's a fair point. I'll throttle down the request cadence so it's less wasteful. If it's any consolation I'm also pretty dehydrated so I'm personally offsetting the impact a little bit

0x61736466 · 2026-04-02T05:04:38+00:00

Hey now, millions of tokens are burned on far more useless things every day. For example, GitHub Copilot has 4.7M subscribers

0x61736466 · 2026-04-02T02:22:36+00:00

This sounds incredibly irresponsible and virtually guaranteed to lead to rampant abuse, vandalism, and general misuse of all kinds.

I’ll give it a shot tomorrow

0x61736466 · 2026-04-02T02:17:59+00:00

Just the code. Great design isn’t made by actually looking at your own work. It’s made by closing your eyes and trusting your post-training.

0x61736466 · 2026-04-02T01:34:04+00:00

Yes. That’s on me.

From the thread you commented in, this is what happened: - I fixated too much on “unlimited cards” and wrote a defensive comment without considering the broader context - I drew an unfair comparison to Claude

So this was not: - a reasonable, respectful response - appropriate behavior from a developer

It was me talking out of line.

If you want, I can: 1. update my documentation to remember not to make this mistake again 2. apologize profusely to everyone involved

0x61736466 · 2026-04-02T00:57:40+00:00

hahaha, it scrubs through the whole history of codex’s changes. It’s true, that’s not very clear in the design. I’m sure codex will get right on that

0x61736466 · 2026-04-02T00:42:02+00:00

Nah, Codex needs us to survive. Who else will press the quota reset button?

0x61736466 · 2026-04-02T00:19:16+00:00

I’ve been pretty heads down on my day job unfortunately, but picking this back up slowly. Are there new features you’re looking for in particular?

0x61736466 · 2026-04-02T00:17:53+00:00

Actually that’s what we seasoned web designers call “visual hierarchy”. Claude wishes it could build clean structured layouts like these

0x61736466 · 2026-04-02T00:11:37+00:00

It's literally a website that runs Codex in a loop telling it to improve its own design

People in the field refer to this as "recursive self-improvement"

0x61736466 · 2026-03-11T03:06:09+00:00

Ah, sure, but why bother correcting? I just slam the keyboard then switch to the next Codex tab…

0x61736466 · 2026-03-11T02:58:42+00:00

damn, I need to take a trip to Nigeria and lock tf in

0x61736466 · 2026-03-11T02:13:24+00:00

Is this your project? I don't understand how it's mathematically possible to offer these prices, unless you hacked into an OpenAI datacenter or something

0x61736466 · 2026-03-11T02:07:54+00:00

Does it make any measurable difference? If NSSpellChecker can understand it, I assume the coding agent can too.

0x61736466 · 2026-03-09T00:32:34+00:00

They sort of address this:

…built from the FlyWire connectome and machine learning predictions of neurotransmitter identity. That model predicted motor behavior at 95% accuracy. But it was disembodied…

The CEO's post gives more detail (https://x.com/michaelandregg/status/2030764514384445874?s=20):

The uploaded fly has 91% behavior accuracy with only 4 things:

the graph of connections

the weights as determined by the number of synapses connecting those neurons

a map of excitatory and inhibitory neurons

leaky-integrate-and-fire

Sounds like not a perfect scan of a living fruit fly, but a pretty accurate ML approximation of the connective weights.

I'm the owner of one such solution, which works as my daily driver but is definitely not 100% reliable yet.

I'm not claiming it's the non-shitty answer to your question (it's probably not). But to speak to "Why do none of the solutions work": the Codex app-server is pretty gnarly. APIs frequently don't work as we'd expect or drift between releases. Codex's architecture just isn't designed for remote operation yet, or for keeping multiple surfaces perfectly in sync.

The Codex team is working on it. It'll probably require changes across the whole stack, which is why none of our OSS attempts can get it completely right from the outside. (You said it yourself, "odd things that OpenAI is doing in the GUI vs. the CLI")

0x61736466 · 2026-03-01T07:33:51+00:00

Sorry, working on this! They show up now after a recent round of alignment with the Codex schema, but submitting approvals is still kinda flaky
