> Ain't nobody got time to pick models and compare features Then don't? Seems like a weird thing to complain about. I just use whatever's available. I like Claude for coding and ChatGPT for generic tasks, that's the extent of my "pick and compare"

I think its a valid complaint. Who wants to constantly spend overhead on maintaining what's current without clear definitions and adding uncertainty to your tooling. It's a total PITA.

Then don't? I don't think it's a valid complaint at _all_.

It's totally fine to just pick one tool (chatGPT, Claude, Gemini) and just use whatever the best default they allow you to use. You'll get 90% of the benefits and not have to think at all.

AI is new and developing at breakneck pace. You can't complain that you want to get bleeding edge without having to do research or change workflows. That's already unrealistic for "normal" fields. It's absurd to expect for AI.

Very preliminary testing is very promising, seems far more precise in code changes over GPT-5 models in not ingesting irrelevant to the task at hand code sections for changes which tends to make GPT-5 as a coding assistant take longer than sometimes expected. With that being the case, it is possible that in actual day-to-day use, Haiku 4.5 may be less expensive than the raw cost breakdown may appear initially, though…

One of the main issues I had with Claude Code (maybe it‘s the harness?) was that the agent tends to NOT read enough relevant code before it makes a change. This leads to unnecessary helper functions instead of using existing helper functions and so on. Not sure if it is an issue with the models or with the system prompts and so on or both.

Helpfer functions exploded over the last releases, id say? Very often I state: "combine this into one function"

another thing I saw in the last days starting: Claude now draws always an ASCII art instead of a graphical image, and the ASCII art is completely useless, when something is explained

You might get better results with https://github.com/oraios/serena I sometimes use it, but I've found just adding to my claude.md something like "if you ever refactor code, try search around the codebase to see if their is an existing function you can use or extend"

Wouldn't that consume a ton of tokens, though? After all, if you don't want it to recreate function `foo(int bar)`, it will need to find it, which means either running grep (takes time on large codebases) or actually loading all your code into context.

Maybe it would be better to create an index of your code and let it run some shell command that greps your ctags file, so it can quickly jump to the possible functions that it is considering recreating.

I am a professional developer so I don't care about the costs. I would be willing to pay more for 4.5 Haiku vs 4.5 Sonnet because the speed is so valuable. I spend way to much time waiting for the cutting edge models to return a response. 73% on SWE Bench is plenty good enough for me.

How do you review code when the LLM can produce so much so fast?

Just read it when it is done writing it.

What do Claude Code users do for tab auto complete, if anything? GitHub Copilot Free tier?

Yeah, that's enough for my usage.

GitHub typically reports that I'm using 25-30% of the free tier, and 100% of that will be from code completions in my editor. I do maybe 3 hours solid coding a day on average.

I also pay for Gemini Pro for non-coding research. I did have it hooked up to my VSCode a few months ago, but it got reset back to GH Copilot at some point and I've not found a reason to fix it.

They previously discussed this some in the context of Opus 4: https://www.anthropic.com/research/end-subset-conversations > We remain highly uncertain about the potential moral status of Claude and other LLMs, now or in the future. However, we take the issue seriously, and alongside our research program we’re working to identify and implement low-cost interventions to mitigate risks to model welfare, in case such wel…

I can't tell if anthropic is serious about "model welfare" or if it's just a marketing ploy. I mean isn't it responding negatively because it has been trained that way? If they were serious, wouldn't the ethical thing be to train the model to respond neutrally to "harmful" queries?

"Protection against malicious use" isn't as cool as "model welfare". I'm renaming my authentication function to "examineCrest()".

This is my default model now. All other are token consumption monsters, leading to 6% usage of the 5-hour-quota with one single submission. I had cancelled my Claude.ai subscription 4 days ago, but this model will likely make me revert this action.

Just writing code is often faster.

Not when you stink at writing code but you’re really good at writing specs

In that case you would be much more valued as a business analyst than as a developer.

People that can and want to write specs are very rare.

because you can have multiple breakpoints with Anthropic's approach, whereas with OpenAI, you only have breakpoints for what was sent. for example if a user sends a large number of tokens, like a file, and a question, and then they change the question.

I thought OpenAI would still handle case? Their cache would work up to the end of the file and you would then pay for uncached tokens for the user's question. Have I misunderstood how their caching works?

not if call #1 is the file + the question, call #2 is the file + a different question, no.

if call #1 is the file, call #2 is the file + the question, call #3 is the file + a different question, then yes.

and consider that "the file" can equally be a lengthy chat history, especially after the cache TTL has elapsed.

Ain't nobody got time to pick models and compare features. It's annoying enough having to switch from one LLM ecosystem to another all the time due to vague usage restrictions. I'm paying $20/mo to Anthropic for Claude Code, to OpenAI for Codex, and previously to Cursor for...I don't even know what. I know Cursor lets you select a few different models under the covers, but I have no idea how they differ, nor do I car…

as mentioned already by the others, using opencode [1] helps with this, if you like the cli workflow. it is good enough and does not need to exceed what the leaders are doing.

when combined with the ability to use github copilot to make the llm calls, i can play with almost any provider i need. also helps if you get its access through your work or school.

for example, Haiku is already offered by them and costs a third in credits.
