1m context in OpenAI and Gemini is just marketing. Opus is the only model to provide real usable bug context.

I'm directly conveying my actual experience to you. I have tasks that fill up Opus context very quickly (at the 200k context) and which took MUCH longer to fill up Codex since 5.2 (which I think had 400k context at the time). This is direct comparison. I spent months subscribed to both of their $200/mo plans. I would try both and Opus always filled up fast while Codex continued working great. It's also direct experie…

Opus 4.6 is nuts. Everything I throw at it works. Frontend, backend, algorithms—it does not matter. I start with a PRD, ask for a step-by-step plan, and just execute on each step at a time. Sometimes ideas are dumb, but checking and guiding step by step helps it ship working things in hours. It was also the first AI I felt, "Damn, this thing is smarter than me." The other crazy thing is that with today's tech, these…

I’ll put out a suggestion you pair with codex or deepthink for audit and review - opus is still prone to … enthusiastic architectural decisions. I promise you will be at least thankful and at most like ‘wtf?’ at some audit outputs.

Also shout out to beads - I highly recommend you pair it with beads from yegge: opus can lay out a large project with beads, and keep track of what to do next and churn through the list beautifully with a little help.

The weirdest thing about Claude pricing is their 5X pricing plan is 5 times the cost of the previous plan. Normally buying the bigger plan gives some sort of discount. At Claude, it's just "5 times more usage 5 times more cost, there you go".

We’ll make it up on volume.

Is it ever useful to have a context window that full? I try to keep usage under 40%, or about 80k tokens, to avoid what Dex Horthy calls the dumb zone in his research-plan-implement approach. Works well for me so far. No vibes allowed: https://youtu.be/rmvDxxNubIg?is=adMmmKdVxraYO2yQ

Thanks for the video. His fix for "the dumb zone" is the RPI Framework: ● RESEARCH. Don't code yet. Let the agent scan the files first. Docs lie. Code doesn't. ● PLAN. The agent writes a detailed step-by-step plan. You review and approve the plan, not just the output. Dex calls this avoiding "outsourcing your thinking." The plan is where intent gets compressed before execution starts. ● IMPLEMENT. Execute in a fresh…

That's fascinating: that is identical to the workflow I've landed on myself.

Source? I ask because I use 500k+ context on these on a daily basis. Big refactorings guided by automated tests eat context window for breakfast.

i find gemini gets real real bad when you get far into the context - gets into loops, forgets how to call tools, etc

I find gemini does that normally, personally. Noticeably worse in my usage than either Claude or Codex.

Random: are you personally paying for Claude Code or is it paid by you employer? My employer only pays for GitHub copilot extension

GitHub Copilot CLI lets you use all these models (unless your employer disables them. https://github.com/features/copilot/cli Disclosure: work at Msft

Disclosure: have to use them via copilot at work. Be glad I don’t write code for nuclear plants. Why does it have to be so hard. Doubly so in JetBrains ides but I’ve a feeling that’s on both of you rather than just you personally. But I still resent you now.

Opus 4.6 is AGI in my book. They won’t admit it, but it’s absolutely true. It shows initiative in not only getting things right but also adding improvements that the original prompt didn't request that match the goals of the job.

The big change here is: > Standard pricing now applies across the full 1M window for both models, with no long-context premium. Media limits expand to 600 images or PDF pages. For Claude Code users this is huge - assuming coherence remains strong past 200k tok.

Looking at this URL, typo or YouTube flip the si tracking parameter?

On the adding improvements and being helpful thing, isn't that part of the system prompt?
