  "transcript": "I’m not saying this is confirmed, but it would explain a lot of what people are noticing with Codex and ChatGPT lately. \n\nA lot of degradation benchmarks seem to use API access, not the subscription product. So when people say “the model hasn’t degraded,” they may only be proving that the API version still performs well.  \nFrom a cost perspective, it would also make sense. Serving millions of subscription users at a flat monthly price is very different from metered API usage. If the ChatGPT/Codex subscription versions were being served with more aggressive optimization, batching, routing, or quantization, that could explain why the experience feels noticeably worse than it did a month or two ago. \n\nI obviously can’t prove it, but GPT5.5 through subscription access does not feel like the same model it was recently. The gap between benchmark claims and day to day Codex usage feels too large to ignore.\n\n\n\n--- Top Comments ---\n\n\n[26 upvotes] there's no question, lol\n\nmake an image on gpt webui\n\nthen make an image on codex\n\nthen make an image on api low\n\n3 completely different tiers of images, and that's just on low - it keeps scaling through to high.\n\nyou think they're just giving out tens of thousands of dollars of xhigh pro api to some guy with a $100 sub or free trial business coupon? cmon bruh\n\nthey don't even allow 4k image gen on codex\n\nand yes, this applies to code quality too\n\n[20 upvotes] Or far more likely people have ridiculously sized contexts, a ton of stored memories and a massive agents.md file.\n\nIt wouldn’t make any sense to bifurcate the inference stack that way, it would be more hassle than it’s worth.\n\n[8 upvotes] Yes, the API can't change, companies and products actually rely on it. Consumer use is a different story. \n\nI also don't think \"the model\" is ever changing, they are just experimenting with the harness, meaning how much each thinking level is, how little tool calls can it make make and still get the same result, etc. \n\n[7 upvotes] this theory tracks. the api vs subscription gap is getting hard to write off as placebo. would explain why my chatgpt outputs feel a full step dumber than playground results on the same prompt",
