| On slightly off topic note: Codex is absolutely fantastic right now. I'm constantly in awe since switching from Claude a week ago. |

| I'm currently "working" on a toy 3d Vulkan Physx thingy. It has a simple raycast vehicle and I'm trying to replace it with the PhysX5 built in one (https://nvidia-omniverse.github.io/PhysX/physx/5.6.1/docs/Ve...) I point it to example snippets and webdocumentation but the code it gens won't work at all, not even close Opus4.6 is a tiny bit less wrong than Codex 5.4 xhigh, but still pretty useless. So, after reading all the success stories here and everywhere, I'm wondering if I'm holding it wrong or if it just can't solve everything yet. |

Just basic stuff. | | |

| ▲ | neomantra 6 hours ago | parent | prev | next [-] | | While I’ve had tremendous success with Golang projects and Typescript Web Apps, when I tried to use Metal Mesh Shaders in January, both Codex and Claude both had issues getting it right. That sort of GPU code has a lot of concepts and machinery, it’s not just a syntax to express, and everything has to be just right or you will get a blank screen. I also use them differently than most examples; I use it for data viz (turning data into meshes) and most samples are about level of detail. So a double whammy. But once I pointed either LLM at my own previous work — the code from months of my prior personal exploration and battles for understanding, then they both worked much better. Not great, but we could make progress. I also needed to make more mini-harnesses / scaffolds for it to work through; in other words isolating its focus, kind of like test-driven development. | |

| ▲ | layer8 7 hours ago | parent | prev | next [-] | | My impression is that it always comes down to how well what you’re trying to do pattern-matches the training set. | | |
| ▲ | embedding-shape 6 hours ago | parent [-] | | When it comes to agents like codex and CC it seems to come down to how well you can describe what you want to do, and how well you can steer it to create its own harness to troubleshoot/design properly. Once you have that down, I haven't found a lot of things you cannot do. | | |
| ▲ | layer8 6 hours ago | parent [-] | | Breaking down and describing things in sufficient detail can be one way to ensure that the LLM can match it to its implicit knowledge. It still depends on what you’re trying to do in how much detail you have to spell out things to the LLM. It’s almost a tautology that there’s always some level of description that the LLM will be able to take up. | | |
| ▲ | embedding-shape 4 hours ago | parent [-] | | Well, not just breaking down the task at hand, but also how you instruct it to do any work. Just saying "Do X" will give you very different results from "Do X, ensure Y, then verify with Z", regardless of what tasks you're asking it to do. That's also how you can get the LLM to do stuff outside of the training data in a reasonably good way, by not just including the _what_ in the prompt, but also the _how_. |

| ▲ | shdh 34 minutes ago | parent [-] | | Exactly this, the SNR is polluted by this anecdata because someone was able to implement a CRUD backend they couldn’t before |
| |
| ▲ | nothinkjustai 2 hours ago | parent | prev | next [-] | | Nah, it only lives up to the hype for crud apps and web ui. As soon as you stop doing webshit it becomes way less useful. (Don’t get mad at me, I’m a webshit developer) | |
| ▲ | wg0 8 hours ago | parent | prev [-] | | Most of the folks are building CRUD apps with AI and that works fine. What you're doing is more specialized and these models are useless there. It's not intelligence. Another NFT/Crypto era is upon us so no you're not holding it wrong. | | |
| ▲ | MattRix 4 hours ago | parent [-] | | This is pretty wrong. Anyone who thinks this stuff is similar to NFTs and crypto hasn’t been paying attention. | | |

| I have also switched from claude to codex a few weeks ago. After deciding to let agents only do focused work I needed less context, and the work was easier to review. Then I realized codex can deliver the same quality, and it's paid through my subscription instead of per token. |

| Codex has been good quality wise, but I hit limits on the Codex team subscription so quickly it's almost more hassle that it is worth. |

| I made this switch months ago, ChatGPT 5.4 being a smarter model, but I’ve had subjective feelings of degradation even on 5.4 lately. There’s a lot of growth in usage right now so not sure what kind of optimizations their doing at both companies |

| I use Codex at home and Opus at work. They're both brilliant. |

| I would switch to Codex, but Altman is such a naked sociopath and OpenAI so devoid of ethical business practices that I can't in good conscience. I'm not under any illusion that Anthropic is ethical, but it is so far a step up from OpenAI. |

| ▲ | nh2 11 hours ago | parent | prev | next [-] | | Cannot you use Codex (which is open source, unlike Claude Code) with Claude, even via Amazon Bedrock? | | |
| ▲ | embedding-shape 6 hours ago | parent [-] | | Codex with Anthrophic's models is not as good as using the models with the harness it was trained in mine for. Same goes vice-versa too. |
| |
| ▲ | bob1029 10 hours ago | parent | prev | next [-] | | I'm with you on the ethical part, but everything is a spectrum. All the AI leadership are some shade of evil. There's no way the product would be effective if they weren't. I don't like that Sam Altman is a lunatic, but frankly they all are. I also recognize that these are massive companies filled with non shitty engineers who are actually responsible for a lot of the magic. Conflating one charlatan with the rest of it is a tragedy of nuance. | | |
| ▲ | subscribed 8 hours ago | parent [-] | | Yeah, but there's distinct difference between "risks their company because they refuse to help with killing little kids" and "happily helping with genocide". One of these is better. |
