Compare AI models by task quality, license, hardware needs, privacy, and operating cost.
Define the task
Decide whether you need chat, coding, extraction, classification, multilingual use, or structured output.
Read the actual license
Open-weight models may have different commercial terms, attribution needs, or usage restrictions.
Estimate hardware needs
Context length, quantization, runtime, and concurrency affect speed and memory.
Evaluate on your own examples
Measure correctness, latency, and stability on representative tasks, not just a leaderboard.
Plan maintenance
Track versions, protect inputs, monitor behavior, and keep a rollback plan.
