gpt2

Use cases

• Text continuation and creative writing prototyping
• Educational demonstrations of autoregressive language model behavior
• Lightweight text generation without GPU hardware
• Fine-tuning starting point for domain-specific generation tasks
• Generating synthetic training data augmentation for NLP tasks

Pros

• MIT license allows unrestricted commercial use
• Minimal memory footprint (<500MB) runs on CPU
• Multi-framework support: PyTorch, TF, JAX, ONNX, TFLite, Rust
• Behavior extensively studied and documented in published literature
• Fast CPU inference at 124M scale

Cons

• Substantially outperformed by modern LLMs on every generation task
• 1024-token context window limits use on longer documents
• No instruction tuning — responses require careful prompt engineering
• High hallucination rate with no factual grounding mechanism
• No multilingual capability; English-only training corpus
