Quick definition
KV cache stores key and value tensors for previous tokens.
- Category: Models
- Focus: model capability and fit
- Used in: Choosing a model that fits latency and cost constraints.
What it means
It speeds up generation by avoiding recomputation. In models workflows, kv cache often shapes model capability and fit.
How it works
Model architecture and scale determine capability. Context length, parameter count, and modality support vary across models.
Why it matters
Model architecture affects capability, context length, and speed.
Common use cases
- Choosing a model that fits latency and cost constraints.
- Selecting longer context for document-heavy workflows.
- Using specialized models for code, vision, or speech.
Example
Long chats generate faster with a cache.
Pitfalls and tips
Bigger is not always better. Match the model to the task and evaluate in production.
