    Stem FAQ

    Qwen2.5-Coder 7B Instruct currently leads Stem and is also the cheapest scored model on this page, at $0.30/M input and $0.30/M output ($0.60 blended).

    Not automatically. Qwen2.5-Coder 7B Instruct leads Stem, but a cheaper scored model can be the better production choice if the quality gap is small. Use the table to weigh Stem against input/output price, context window, and related evals.

    How often is the Stem leaderboard updated?

    Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 30, 2026. Treat it as a current index, not a one-off blog post.

    What is Stem?

    Stem is a public LLM eval (the Stem score). This page ranks models that have published a score, next to live API prices.

    Where is the Stem leaderboard?

    This page is the Stem leaderboard. Models are sorted by Stem, 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.

    How is this Stem ranking different from the official board?

    Official eval pages own the methodology. This page keeps the published Stem score next to live API $/M so you can pick a production SKU, not only a trophy number.
