This topic is less about “what models can do” and more about when they fail and how to operate them safely.
We prioritize evergreen concepts, common misconceptions, and practical decision rules.

Quick orientation

• Read in the order definition → misconceptions → practice.
• Compare models by your constraints (latency, cost, security, quality), not a single benchmark number.
• Specs and policies change quickly, so always check the as-of date inside each post.

Where to start

• Start with an Explainer to build the mental model,
• then move to HowTo/Troubleshooting posts for operational reality,
• and finish with Deep Dives for clear trade-offs and decision criteria.
