GSM8K is a public LLM eval (the GSM8K score). This page ranks models that have published a score, next to live API prices. Official methodology: GSM8K (https://github.com/openai/grade-school-math).
This page is the GSM8K leaderboard. Models are sorted by GSM8K, with input and output token prices on the same row so you can weigh score against cost. Official boards often omit price; that comparison is the point of this index.
The official GSM8K page owns the methodology. This page keeps the published GSM8K score next to live API $/M so you can pick a production SKU, not only a trophy number. Source: https://github.com/openai/grade-school-math
