Frequently Asked Questions

Peft vs Surge AI: which should you choose?

If you're a developer or researcher needing to fine-tune large models on limited hardware, Peft is the free, open-source choice with extensive methods. If you're a frontier AI lab requiring expert human feedback for RLHF, red teaming, or benchmark creation, Surge AI's curated workforce and proprietary evaluations justify its contact-based pricing. Choose based on whether your bottleneck is compute or human annotation quality.

Can I use Peft without Hugging Face libraries?

Peft tightly integrates with Transformers, Diffusers, and Accelerate; it's designed for the Hugging Face ecosystem.

Does Surge AI provide automated evaluations?

Surge focuses on human expert grading, though it offers programmatic APIs. For fully automated eval, other tools may be better.

Can I combine Peft and Surge AI?

Yes, use Surge for expert-annotated data and Peft for fine-tuning, though no direct integration exists.

What hardware do I need for Peft?

Peft reduces memory via quantization and LoRA; models like Llama 3b can run on a single consumer GPU.

Is Surge AI suitable for simple sentiment labeling?

No, it's overkill; Surge's expert workforce is for complex reasoning tasks.

Does Peft work with non-transformer models?

Peft is primarily for transformer-based models, integrated with Diffusers and Transformers.

How does Surge AI ensure quality?

Surge uses domain experts (doctors, lawyers) and proprietary benchmarks to validate performance.

Are there any usage limits for Peft?

No, as open-source software, there are no usage limits.
