A successor only counts if they have a name that isn't o3.x or o3-x or something that contains o3. o4 counts, o5 counts, reasoning models with a different name pattern that are clearly better than o3 count.

• Update 2025-04-17 (PST) (AI summary of creator comment): Benchmark Results as Evidence:

  • The successor does not need to be officially released; showing benchmark results similar to those provided for o3 before January when the market was created is sufficient.

  • This clarification means that a demonstration of performance through benchmarking can count as identifying a successor even without a formal launch.
