Alpaca-13B

Instruction-Tuned Open LLM for Scalable Research & Chat AI

What is Alpaca-13B?

Alpaca-13B is a 13-billion-parameter instruction-tuned large language model, built by Stanford University on top of Meta’s LLaMA-13B foundation. As a larger sibling to Alpaca-7B, it is designed to provide better reasoning, fluency, and response consistency in instruction-following tasks.

Fine-tuned using the self-instruct methodology on 52,000 high-quality examples generated with OpenAI's text-davinci-003, Alpaca-13B is ideal for research institutions and developers looking for stronger NLP performance under a fully open, transparent pipeline, though it remains restricted to non-commercial use.

Key Features of Alpaca-13B

13B Parameters Based on LLaMA-13B

Delivers improved output depth, coherence, and multi-turn conversational ability compared to smaller models.

Instruction-Tuned with Self-Instruct

Trained on 52K instruction/response pairs to handle summarization, rewriting, Q&A, reasoning, and more.

Built for Open Research & Education

Designed for academic labs, AI safety researchers, and educators exploring model behavior and prompt design.

Scalable Yet Accessible

Optimized for high-end single-node GPU setups or research clusters, runs efficiently with quantized variants.

Transparent & Reproducible

Released with full dataset and training pipeline, allowing others to replicate or extend the research methodology.

Non-Commercial Use Only

Due to LLaMA licensing, Alpaca-13B is restricted to non-commercial and academic experimentation.

Use Cases of Alpaca-13B

Use to study model alignment, long-form reasoning, prompt structure, and chain-of-thought generation.

Incorporate into university courses, workshops, or training programs for hands-on LLM teaching.

Test AI assistants and chatbot logic before transitioning to production-grade or commercially licensed models.

Evaluate how model size impacts performance across instruction-tuned benchmarks like HELM or Super-NI.

Adapt to specific academic or technical domains using supervised fine-tuning on curated datasets.
