hf-generate-internals

What problem does it solve?

This Skill helps engineers understand the internal flow of HuggingFace Transformers generate(), including the distinction between post-processor scores and raw logits, how LogitsProcessors shape outputs, how the KV cache is managed, and how StoppingCriteria and chat templates interact, enabling deeper debugging and safer customization.

Core Features & Use Cases

• Reference for generate() internals across the prefill and decode stages, aligned with transformers 5.3.0.
• Clarifies how scores, logits, and processor pipelines relate and how KV caches evolve token by token.
• Guides debugging and optimization scenarios, including memory considerations and custom stopping logic.

Quick Start

Review the Generate internals guide to instrument your own generation workflow and observe scores, logits, and cache updates during generation.
