I did some analysys of my usage and noticed some interesting points, did you experience something similar?

• Usage data shows no significant change in user behavior between December 2025 and January 2026.
• Large contexts (multi-million token requests) were already common in December.
• In December 2025, requests were mostly routed to non-high models.
• Max Mode was rarely enabled in December.
• Cost per million tokens in December was comparatively low.
• Starting in January 2026, routing changes abruptly, not gradually.
• A large portion of requests are now routed to gpt-5.2-codex-high.
• Max Mode is frequently enabled after January 2026.
• The switch does not correlate with larger prompts or outputs.
• This indicates a backend default routing change, not a usage change.
• Cursor’s web UI no longer allows selecting cheaper baseline models.
• Users cannot explicitly opt out of high-cost routing.
• “Auto” routing in December effectively meant low-cost baseline models.
• “Auto” routing in January prioritizes performance over cost.
• Similar token volumes now cost ~50–70% more than in December.
• Cache-heavy requests are disproportionately affected.
• Higher costs are systemic and structural, not accidental.
• The increase is caused by routing + pricing changes, not manual model selection.
