When I say GPT-4 class I'm talking about being comparable to the GPT-4 that was released in March 2023.
The Llama 3.3 70B model is clearly no way near as good as today's GPT-4o family of models, or the other top-ranking models today like Gemini 1.5 Pro and Claude 3.5 Sonnet.
To my surprise, Llama 3.3 70B is ranking higher than Claude 3 Opus on https://livebench.ai/ - I'm suspicious of that result, personally. I think Opus was the best available model for a few months earlier this year.
There's still a gpt-4 model available via the OpenAI API, but it's gpt-4-0613 from June 2023 - the March 2023 snapshot gpt-4-0314 is no longer available.
I ran one of my test prompts against that old June 2023 GPT-4 model here: https://gist.github.com/simonw/de4951452df2677f2a1a3cd415168...
I'm not going to try for an extensive evaluation comparing it with Llama 3.3 though, life's too short and that's already been done better than I could by https://livebench.ai/
The bar for GPT-4 was so low that unambiguously clearing that threshold should be pretty easy.
What I care about is the things that they're proven to be good at - can I do those kinds of things (RAG, summarization, code generation, language translation) directly on my laptop?
The default llama3.3 model in ollama is heavily quantized (~4 bit). Running the full fp16 model, or even an 8-bit quant wouldnt be possible on your laptop with 64G RAM.
There is no llama 3.3 405B to test, 3.3 only comes in 70B. Are you sure you aren't thinking of llama 3 or 3.1?
