Context Window Hype
Most users rarely consume massive amounts of context efficiently.
Benchmark Obsession
Benchmarks show capability—not production performance.
Speed Is Ignored
Latency dramatically changes user experience.
Missing ROI Analysis
Organizations buy productivity—not benchmark trophies.
