Fine-tune your own Llama 2 to replace GPT-3.5/4

>>kcorbi+(OP)
For translation jobs, I've experimented with Llama 2 70B (running on Replicate) v/s GPT-3.5;

For about 1000 input tokens (and resulting 1000 output tokens), to my surprise, GPT-3.5 turbo was 100x cheaper than Llama 2.

Llama 7B wasn't up to the task fyi, producing very poor translations.

I believe that OpenAI priced GPT-3.5 aggressively cheap in order to make it a non-brainer to rely on them rather than relying on other vendors (even open source models).

I'm curious to see if others have gotten different results?

You can run 70B LLAMA on dual 4090s/3090s with quantization. Going with dual 3090s you can get a system that can run LLAMA 2 70B with 12K context for < $2K.

I built two such a systems after burning that much in a week on ChatGPT.

Are there any good resources related to expanding context windows, or even just the mechanics of how they actually work as properties of a model?
