This market resolves yes if on February 15th, 2026, when I think to use an LLM, I will default to asking Opus 4.5 first. It resolves no if I default to using any other model first.

Some history of my daily drivers:

GPT4 from March 2023 to December 2024

o1 from December 2024 to April 2025. o3 from April 2025 to August 2025. GPT5 from August 2025 to September 29th, 2025. Sonnet 4.5 from September 29th to November 19th 2025. Gemini 3 from November 19th, 2025 to November 24th 2025. Opus 4.5 from November 24th to ???.

My use cases are generally coding, brainstorming writing ideas, and copy editing. I dislike model hallucinations and I care a decent bit about model personality. However, I generally just default to the most intelligent model if such a model exists.

Since this is subjective I will not trade on this market.
