If you're building AI agents or RAG pipelines that need fresh, structured web data, Spider Cloud's pay-per-page model (starting at $0.003/1k pages) and AI Studio make it a cost-effective choice. If you're a researcher or hobbyist fine-tuning LLMs on a budget GPU, Bitsandbytes is essential — it's free, open-source, and the de facto quantization library for PyTorch. They solve completely different problems, so buy the one that matches your task.

Frequently Asked Questions
Bitsandbytes vs Spider Cloud: which should you choose?
If you're building AI agents or RAG pipelines that need fresh, structured web data, Spider Cloud's pay-per-page model (starting at $0.003/1k pages) and AI Studio make it a cost-effective choice. If you're a researcher or hobbyist fine-tuning LLMs on a budget GPU, Bitsandbytes is essential — it's free, open-source, and the de facto quantization library for PyTorch. They solve completely different problems, so buy the one that matches your task.
Can Bitsandbytes be used for web scraping?
No. Bitsandbytes is for quantization of PyTorch models, not data extraction. Use Spider Cloud for web scraping.
Does Spider Cloud run on my GPU?
No, it's a cloud API. You send requests and get back structured data. No GPU is needed.
Is Bitsandbytes completely free?
Yes, it's open-source under MIT license with no usage fees. You only need a CUDA-compatible GPU and PyTorch.
How does Spider Cloud charge for failed requests?
Failed requests are not billed. You only pay for successful page crawls.
Can I use Bitsandbytes with TensorFlow?
No. Bitsandbytes is PyTorch-only. For TensorFlow, look into other quantization libraries.
Does Spider Cloud support real-time data streaming?
Yes, via WebSocket Browser AI commands (Act, Extract, Observe) for live interactions.
What are the output formats of Spider Cloud?
Markdown, HTML, JSON, CSV, XML, and plain text.
Does Bitsandbytes support 4-bit quantization?
Yes, QLoRA provides 4-bit base model quantization for training, plus LLM.int8() for 8-bit inference.
