I spent two months on the side building a custom Halloween Controller PCB through Codex using GPT Sol 5.6 and later Astra when it came out. It was still a lot of work because you can't one-shot something like this and send it off to manufacturing, but holy cow did it ever speed up the process.

I wrote a pretty length article on how I went about it, and what worked well and where the model still struggles. This is clearly the future though, and it was a lot of fun to do.

For those wondering, this is to control halloween props and effects in haunts. We run a big haunted circus on Halloween every year, and I got tired of building custom Arduino boards for everything.

I find GPT's electronics knowledge to be particularly strong compared to Claude. This has been true since at least GPT 5.0 from my experience. They are cooking.

I've never had something like this happen in a year of using Codex. Anyone else have an experience like this? Needless to say, I'll probably be sticking to Sol/Luna for now...

Tibo's doing everything he can to make us forget about the resets lmao

Personally GPT-6.1 Terra replaced deepseek. Can't find a better Intelligence - $/task.

What would you drive from point A to B?

Here we go again! Check your limits and have fun.

I disagree with a lot of the recent discourse regarding why does Terra even exist – it seems to occupy the right slot for a worker agent being orchestrated by Opus/Astra. Most of my work is fully autonomous now, and I've had difficulty figuring out the best worker agents.

Sol eats up usage way too quickly to be useful, and Luna needs so much hand-holding that my orchestrator blows through its usage. Opus as orchestrator + Terra as worker + Sol/Astra/Argon as reviewer depending on complexity seems to be hitting the right balance.

I do wish they increase the limits for Terra though. It's a good model, just needs to be closer to Luna than Sol when it comes to usage and it would be golden.

3% Till left

The narrative that Opus 5.5 destroys OpenAI's models is pretty misleading.

Look at this Artificial Analysis chart. OpenAI delivers comparable intelligence at a fraction of the cost across much of the range.

I know the chart was updated today, but it shows how misleading judgments based on gut feeling and vibes can be. Sol 6.1 has been incredibly cost-efficient since launch, yet was widely dismissed as "useless."

Sol 6.1 has a reputation for being slow, yet Terra 6.1 now completes tasks over 3x faster than Sol and Astra in OpenAI's Agents' Last Exam benchmark.

Why aren't cost and speed getting more attention in model comparisons?

I keep getting so frustrated when trying to get codex to design a web template/UI/UX it just constantly comes up with absolute standard stuff or complete garbage and it seems to be profoundly good at leaving lots of layout and responsiveness bugs in there.

I have tried several models up to Astra Ultra, but it keeps dissapointing.

Now if this was the same across the board I would get it, but using GPT chat on pro is the absolute opposite, it creates things that look like they are designed by some sort of design god and it understands what you want, it creates multiple very cool variations which you can then follow through on, it's just absolutely epic, but I don't like relying on using chat everytime to generated templates/design just to be able to use them in codex.

Perhaps there is some built in promt in chat which I am not using, but I would love to hear from others if they figured it out?

Obviously the accounts will be ungrandfathered, but does anyone have information on exactly what will happen to remaining allowances on that date? How will any remaining allowance for the week get transferred to the new allowance regime? For example, if I have used more than half of my grandfathered 20x limit - will I get move instantly to 0% allowance remaining? I believe this is what happened to some other account holders recently when their allowance was changed behind the scenes.

Also, when on October 29 will the allowances be changed - end of day Pacific Time? Local Time?

There does not seem to be good communication on this...

Hey Everyone, what's the suggestion on burning the 62,500 credit grant given for halving our usage? Downgrade to the $100 plan and burn or can we burn them on the $20 plan?

For context, I stopped paying on my $200 plan, but since they so graciously gave these credits as a consolation for rectal ablation, I'm interested in knowing how the community is using their credits.

Edit: I mean should I just burn them on a $20 plan, downgrade to a $100 plan or keep the $200 until they run out? I moved to Claude but their usage has been rough the past week so I'm wondering how best to spend this usage.

When it first came I immediately switched to it hearing how it's supposed to be way efficient and boy it was! I'd get 4h straight on 6.1Sol Max inside the 5h windows! On Plus!

But then we got a nerf I guess because it started to only work for an hour so that was when I new the fun is gone and decided to try xhigh and I'd get 3.5-4h using it inside the 5h limit which is fairly good.

Yesterday though it became 2.5-3h and barely getting the job done so I started to introduce a couple of skills in hopes of reducing usage and increasing quality or at least increase quality expecting increased token usage then try to cut token usage to balance things, I did also have the agents. md be configured properly and introduced those skills:
(Caveman, Superpowers, Ponytail, RTK, Graphify, Headroom, ECC)

I had caveman set to ultra even yet somehow quality got worse and I barely get a single hour of work in the 5h limit!!

So now I need to know is my setup the problem or limits got nerfed today again?
And if I am doing it wrong how to fix it?

My commentary about the model at the bottom of the post.

For some time now I have been measuring GPT model's allowances and several others. Because a new GPT model was released, it is time for an update.

Unfortunately, the trend continues. With each new model release, the new model gets less quota in API-equivalent compared to the previous ones. Also, unfortunately, the claim that we get 2x the usage out of Terra compared to Sol is a straight-up lie.

Measured on a fresh context window on a Plus account for accurate measurements, like always. Context limited to 272k to make sure I don't go past the double price. I didn't check Luna or Astra yet, but Sol remains as it was. Generally the allowance for models is constant after their release from my measurements; only the new ones have less.

For Pro, simply multiply by 5/10/25.

As a bonus, here is a table of the "real cost" per million tokens and total amount of tokens per real dollar spent, also compared to DeepSeek v4.1 Flash (off-peak pricing), GLM 5.3 (off-peak), and Muse Spark. If you use OpenCode, Ollama Cloud, or CommandCode subscriptions, the price for DeepSeek goes down. At peak hours, the price for DeepSeek and GLM is 2x. Ollama has its own infrastructure with ZDR and uses different peak hours.

For z.ai plans, you can subscribe quarterly or yearly for better ratings.

Tokens per $1 assumes 97% cached input, 2.5% uncached input, and 0.5% output.

* - Claude charges for cache writes. The pricing is averaged. I used these numbers. Their findings for Codex match mine, so I trust them.

My commentary about the new model. It is the first and only model that simply doesn't want to work. During a simple mechanical refactor, it stopped 3 times, telling me it is only finished partially. At the end it changed a part of the code, ran tests, saw several errors, reverted the change, and reported that it is only partially done. I ran it on XHigh reasoning. I doubt Max would change much, but it is not out of the question. This is not a model for agentic coding, that's for sure. It is quick, but very unreliable.

I double-checked 6.1 Sol allowance; it is still the same as it was, so I recommend staying with 6.1 Sol or Luna. I have no use for 6.1 Terra. I see no reason in using it for coding when it gives us almost the same usage as 6.1 Sol. If you don't want your job done, use the new Terra, I guess. It may have a potential as an orchestrator, but that requires further testing.

Unfortunately, OpenAI continues its tactic to nerf the usage with each new model. By my own measurements, they don't nerf the usage of each model after they are released; they are nerfed from the release (compared to previous ones). You can see the trend with 5.6 Sol -> 6 Sol - 6.1 Sol -> 6.1 Terra. We are at the third of the 5.6 allowance now, which was also lowered compared to 5.5.

I asked it to chexk for bugs and possible improvements to a chatgpt "sites" project i have. Its a small PCB milling tool with 3D views i use at work.

I asked it to not apply any changes, just check, i was using it on Max mode and it decided to implement either way.... is this just ridiculous, according to the reasoning charts posted by openai such dumb little things shouldnt be a problem for such "intelligent" models... well ill keep using Claude i guess.

Edit. Not only it decided to implement when i said not to, wich should not happen at the reasoning level of such model. But the research it did was quite lame.

One thing it did kinda ok was improving the UI, but Claude opus 5.5 on lowest mode destroyed terra either way... and i didnt even see the % go down, where as terra it did quite a bit, so Terra is not even token efficient ...

Since yesterday, Codex doesn't seem to suggest the next message when the task is done (autocomplete/autosuggestion). Do you have the same experience ?

I run Codex through MCP servers a lot, and the browser ones all had the same shape: install Playwright, launch a browser, log into everything again, hope nothing is behind a captcha. Fine for scraping, useless for "check my GitHub notifications" or "what's in my Jira".

So I built the Firefox equivalent. Add-on plus a native messaging host, helper serves MCP over Streamable HTTP on localhost:8901 with a bearer token, and the agent drives the profile I'm already logged into: open tabs, accessibility snapshot with refs, click/type/scroll/wait, screenshots, bookmarks, history, downloads.

It's 45 tools, MPL-2.0, no telemetry. Works with Codex, Claude Code, Cursor and anything else that speaks MCP.

https://github.com/hamb1y/foxhand

https://addons.mozilla.org/firefox/addon/foxhand/

Two things I'd flag: the helper binary has to be installed (one line), and prompt injection is real. If a page tells the agent to do something, it can.

Curious if anyone here runs Codex against a browser at all, and how you deal with session state

LOL, I found this really funny that it would ask for permission

From what I heard, in 3 days Pro account usage limits are going to be halved. Is this really going to happen? The current state is already unsustainable, especially after Codex has become practically useless compared to competition.

On my $500 plan, running 8 concurrent tasks with delegation between Sol 6.1 and Luna 6, I can work for around 16–18 hours. After halving the limits, that would drop to just 8-9 hours.

The only thing that can just let me keep working are the resets. But I'm so damn tired of that circus show, and definitely those resets will also be stopping slowly.

A few months ago, I was running agents 24/7 on two $200 accounts non-stop for the full month that’s a huge difference. If I still want my agents to run 24/7 across all my projects, I will need $2,000 per day, which is going to cost $60,000 per month, that's insane difference, what's going on? Who will even stay with these insane prices in comparison to competition?
