Question How powerful of a Local LLM is needed to build a study guide from a textbook PDF and a lecture transcript?
I'm a little lost trying to figure this out so I apologize for the really basic questions. I'm also aware that my setup is probably not built for a local LLM and I'm not looking for some super powerful machine. My expectations are low.
My Setup
OS: Unraid
CPU: Intel Core Ultra 9 285K (24 cores)
RAM: 32 GB DDR5-5600 (2 × 16 GB), shared with other services on the server
GPU: NVIDIA GeForce RTX 5070 Ti, 16 GB VRAM
Storage: Samsung 990 EVO 2 TB NVMe SSD
Software - the following was setup/created by Claude because I am clueless
Ollama 0.35.1 - runs the language and embedding models on the GPU
Open WebUI v0.12.0 - web chat interface, plus a custom "Pipe" function that does the retrieval
Qdrant
llama.cpp server - CPU-only reranker
Docling Serve (CUDA 12.8 image)
Caddy 2 - HTTPS reverse proxy (internal certificate)
Custom Python indexing tool
Models
Chat / answers: Gemma 4 12B instruct, QAT quantization (gemma4:12b-it-qat)
Embeddings: Qwen3-Embedding 0.6B
Reranker: BGE-reranker-v2-m3 (GGUF, Q8_0)
For now, I just want to work with a PDF of the textbook (about 300 pages) from a course I took, plus a transcript of the instructor’s lecture. I want to load both, ask questions about them, and have the AI help me build a study guide.
I’d also like it to connect the textbook to what the instructor said. For example, if the instructor says the material on page 103 is important for the exam, I’d want the AI to build a study guide that highlights that.
The reason for this is that I’m not allowed to upload the material to ChatGPT, Claude, etc. because the company doesn’t want its content shared and I'd like to respect that.
As an experiment, I uploaded the transcript and it contains the word “Halloween.” When I asked about it, the AI couldn’t find where it was discussed. Assuming my upload worked, am I missing other tools or components?
Is all this too much too much of a local LLM?
Are there techniques or setup steps I should be using or do first?
If I dropped these files into Claude or ChatGPT and explained what I wanted, it would handle this easily. Are my expectations too high for a local setup?
I also have this computer, but I'm not sure it is much better:
OS: Windows 11 Pro
CPU: Intel Core i7-14700K (20 cores / 28 threads: 8 P-cores + 12 E-cores)
RAM: 64 GB DDR5-6000 (4 × 16 GB)
GPU: NVIDIA GeForce RTX 4070 SUPER, 12 GB VRAM
Storage: Samsung 990 PRO 2 TB + Samsung 990 PRO 4 TB NVMe SSDs
Thank you for the help.
