It sounds like you don’t need immediate llm responses and can batch process your data nightly? Have you considered running a local llm? May not need to pay for api calls. Today’s local models are quite good. I started off with cpu and even that was fine for my pipelines.
Though haven't done any extensive testing then I personally could easily get by with current local models. The only reason I don't is that the hosted ones all have free tiers.
Do they or any other providers offer any improvements on the often-chronicled variability of quality/effort from the major two services e.g. during peak hours?
As much as I like the Claude models, they are expensive. I wouldn't use them to process large volumes of data.
Gemini 2.5 Flash-Lite is $0.10 per million tokens. Grok 4.1 Fast is really good and only $0.20. They will work just as well for most simple tasks.
Pretty straightforward. Sources dump into a queue throughout the day, regex filters the obvious junk ("lol", "thanks", bot messages never hit the LLM), then everything gets batched overnight through Anthropic's Batch API for classification. Feedback gets clustered against existing pain points or creates new ones.
Most of the cost savings came from not sending stuff to the LLM that didn't need to go there, plus the batch API is half the price of real-time calls.

I haven't thought about that, but really want to dig in more now. Any places you recommend starting?
Can you suggest any good llms for cpu?
Following.
Agreed, I'm pretty amazed at what I'm able to do locally just with an AMD 6700XT and 32GB of RAM. It's slow, but if you've got all night...
This is the way. I actually mapped out the decision tree for this exact process and more here:
https://github.com/NehmeAILabs/llm-sanity-checks
That's interesting. Is there any kind of mapping to these respective models somewhere?
Yes, I included a 'Model Selection Cheat Sheet' in the README (scroll down a bit).
I map them by task type:
Tiny (<3B): Gemma 3 1B (could try 4B as well), Phi-4-mini (Good for classification). Small (8B-17B): Qwen 3 8B, Llama 4 Scout (Good for RAG/Extraction). Frontier: GPT-5, Llama 4 Maverick, GLM, Kimi
Is that what you meant?
Consider using z.ai as model provider to further lower your costs.

This is what i was going to suggest too.
Or minimax - m2.1 release didn't make a big splash in the news, but it's really capable.
Will take a look!

consider this for addtl cost savings if local doesnt interest you - https://docs.cloud.google.com/vertex-ai/generative-ai/docs/m...
Have you looked into https://maartengr.github.io/BERTopic/index.html ?
Are you also adding the proper prompt cache control attributes? I think Anthropic API still doesn't do it automatically
No I need to look into this!
Can you discuss a bit more of the architecture?

You also can try to use cheaper models like GLM, Deepseek, Qwen,at least partially.
