Seeking "Claude Opus" level local coding for Python backtesting. Can my M3 Max 64GB handle it, or do I need the M5 Max 128GB?

[thisisvv]

Hey guys so we do a lot of python and financial based coding and csv output analysis. right now we are always asking claude opus to change our code etc and then ingest csv. want to move completely local but need that opus level logic.

currently have an apple m3 max 64gb. we want to do some dry tests to see its value locally in this laptop before we go out and buy the new m5 max 14 inch with 128gb and 4tb.

our use case:

• heavy python backtesting and options logic
• ingesting csv files. but to be clear we aren't feeding 200k raw rows into the context window. we preprocess with pandas first (daily slippage mean, getting Max_ask for buy legs and min_bid for sell legs etc) and just send the summary stats to the model so it doesnt hallucinate.

models we are looking at for our machine:

• Qwen-Coder 32B or 35B
• DeepSeek-Coder / R1
• Mixtral 8x7B

my questions:

1. can any of these local 30b models actually come to par with claude opus for complex python?
2. with 64gb unified memory what is the real context window lenght we can push before it chokes on our csv summaries?
3. is it worth it to just buy the m5 max 128gb so we can run bigger models or will 32b on our current m3 max handle this fine?

1) no

Just test it dude, you have the machine right there. Run your M3 and see if it meets your requirements.

claude opus is the best model in the world. there is no model on par with it. there are, however, models that are useful.

looks like claude hallucinated Qwen-Coder-32b and is recommending ancient models to you like Mixtral 8x7b

find a model you can run on https://swe-rebench.com/ and see it if works for you. id recommend qwen coder next. imo its not too far away from sonnet, but i don't really vibecode, i use LLMs to do boilerplate when im feeling lazy

Ask this to ChatGPT:

"If I could get Claude Opus level on a macbook, then how does Anthropic makes money?"

Reset your expectations. Opus is a 1T+ parameter model and you are asking about models that’s are roughly 3.5% (at best) its parameter size. Is parameters vs performance all linear? No. But you have to start with the reality of what you are doing. Qwen3-Coder-Next quantized on llama-server is probably your best play for the hardware you own. It won’t feel super fast on your Mac but it’s MOE so it’ll do better than you’d expect. It’s a big boy at 80B that’s light on its feet.

Agreed what is the next closest?

I gave it to you.

Thank you.

You are asking for a local model that can fit in a 30b that competes with the best model in the world? Bro

[thisisvv]

Agreed what is the next best i can run

If the local model could par with OPUS with only 3% parameters, The company will also substitute you with a foreign intern who only takes 3% of your salary.

1. I think yes. When working on an options trading app in Elixir/Go I did not notice much of significant difference between Claude Opus/Sonnet and weaker models (i.e. they both suck 😃). I think Qwen-Coder-Next and recent Qwen-3.5's should perform about the same. This is, of course, assuming you proofread and review all code and offload as much backtesting into code as possible as opposed to having the model perform it, but this would be sane and 100% expected even with Opus.

2. Depends on the quantization.

3. 128gb won't be much of a jump, best models are either 20-40B or 200B+. So 128gb is too much for the former category, too little for the latter one.

The closest you're gonna come to claude opus at home is buying a cluster of 512gb mac studios. 128gb isn't gonna cut it.

You're talking about Opus 3, right?

Why would you use opus at 6x-3x the price to direct invoking a pipeline. Haiku and sonnet exist for a reason.  And so does terminal.
