Model cards and ids

Learn in five minutes

• A model id is a name you pin, because names move.
• A model card should say limits, data, and intended use. Confirm the card you rely on.
• Open-weight and hosted models are different operational choices.
• This lab does not rank this month's products.
• Write 'confirm before relying' next to any id you did not re-check.

Copying a model id from a 2024 blog into a 2026 script without checking is how labs rot. Pin the id in your own note and date the check.
