What counts as a flagship? The most capable model each lab offers. Not fine-tunes, not small variants, not beta patches. The big one.
In AI, 90 days without an upgrade feels like a lifetime. A year is geological. Meta shipped Llama 4 in April 2025 and hasn't released a successor. Meanwhile, OpenAI and Anthropic shipped new flagships in early 2026.
Data verified March 2026. Counters tick from each model's public release date. This page has no API calls. Pure client-side math and existential dread.
No data collected. No APIs called. Just timestamps and arithmetic.
