The pricing page clearly states a 128K context window. However, since launching o3, the only models that seem to support this are the GPT-4o and o1-pro models.
The former o1, and o3-mini models handled the larger context. But the new models appear to be limited as if I was on the “Plus” tier when I’m actually on the $200/month pro tier.
Yes, i noticed this problem in april (when o3 full model was introduced). I actually partly shifted to Gemini now - it is kinda still bad overall, but the context window is enormous.
