When to pick which
Sonnet 5 is both newer and cheaper: $2/$10 versus $3/$15 per million tokens, a one-third saving with better benchmark scores. Both have a 1M-token context window. For any new project, Sonnet 5 is the obvious choice. Sonnet 4.5 remains relevant only if you have an existing production system with prompts and evals tuned against it. Model upgrades can subtly shift tool-calling behaviour and output style, so test before migrating. If you are on 4.5 today, the migration usually pays for itself in a month of token savings alone.
