Eval vs VRAM
Eval (Model Evaluation) and VRAM (Video Random Access Memory) both come up in ai & ml conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: Eval refers to model evaluation, while VRAM refers to video random access memory — they describe different things even when they show up in the same sentence.
Eval — Model Evaluation
The systematic testing of an AI model's outputs against expected behavior — accuracy, safety, format adherence, regression. Without evals, every prompt change is a vibe-based deploy.
VRAM — Video Random Access Memory
High-bandwidth memory on a GPU that holds the model weights and activations during inference. VRAM — not raw compute — is usually the first ceiling you hit when you try to run a serious model locally.
When to use Eval
Reach for "Eval" when the conversation is specifically about model evaluation. The systematic testing of an AI model's outputs against expected behavior — accuracy, safety, format adherence, regression. Without evals, every prompt change is a vibe-based deploy.
When to use VRAM
Reach for "VRAM" when the conversation is specifically about video random access memory. High-bandwidth memory on a GPU that holds the model weights and activations during inference. VRAM — not raw compute — is usually the first ceiling you hit when you try to run a serious model locally.
FAQs
What is the difference between Eval and VRAM?
Eval stands for Model Evaluation — The systematic testing of an AI model's outputs against expected behavior — accuracy, safety, format adherence, regression. Without evals, every prompt change is a vibe-based deploy. VRAM stands for Video Random Access Memory — High-bandwidth memory on a GPU that holds the model weights and activations during inference. VRAM — not raw compute — is usually the first ceiling you hit when you try to run a serious model locally.
Are Eval and VRAM the same thing?
No. They're often used in the same conversation because they're related, but they describe different concepts. Eval = Model Evaluation. VRAM = Video Random Access Memory.
When should I use Eval vs VRAM?
Use Eval when you're specifically referring to model evaluation. Use VRAM when the topic is video random access memory.
