02·Which effort for which task
The sweet spot, per task
Cheapest effort tier that keeps ≥96% of this model's peak quality on the benchmarks behind each task type. Below the floor number, quality is not okay — it just fails quietly.
Everyday writing & Q&A
MediumChat, drafting, summaries, general questions.
Code assist
HighAutocomplete, single functions, small fixes.
Coding agents
HighReal repos, multi-file changes, end-to-end tickets.
Math & quantitative
HighDerivations, statistics, financial models.
⚠ at Low: only 70% of peak — avoid
Hard research problems
HighNovel, frontier, genuinely difficult questions.
⚠ at Low: only 78% of peak — avoid
Agents & tool use
HighLong workflows with tools, policies, and state.
