What Claude Sonnet 4.6 is best for
The best balance of speed, intelligence, and cost — most production routes that don’t need the frontier tier.
Use it for most production routes that need solid quality without frontier pricing. Avoid it for trivial, high-volume calls (route those down) and the very hardest reasoning (route those up).
When to choose Claude Sonnet 4.6
The workhorse. Pick Sonnet 4.6 over Opus when you want strong quality at a third of the input price and most of your traffic is not frontier-hard — which for most products is the majority of it. Move the genuinely hard routes up to Opus.

Cutting your Claude Sonnet 4.6 bill
The headline price isn’t the lever — usage pattern is. The reductions come from routing low-stakes calls to a cheaper tier, caching stable prefixes, batching non-urgent work, and gating it all behind evals so quality holds. The full method — the same one that takes 30–60% out without regressions — is the LLM cost optimization playbook.
Context window: 1M tokens
Claude Sonnet 4.6’s context window bounds how much it can consider at once — system prompt, history, retrieved docs, and the response all draw from those 1M tokens, with up to 64K reserved for output. A larger window enables whole-codebase reasoning and long documents, but using more of it costs more per request — so retrieval and caching still matter even when the window is large.
Cheaper alternatives to Claude Sonnet 4.6
By blended cost (3:1 input:output). The right swap depends on whether quality holds on your routes — always validate with evals.
