Sonnet 4.6 is not retired
Claude Sonnet 5 is the recommended successor and new default, but Claude Sonnet 4.6 stays fully available. There is no forced-migration deadline.
Sonnet 4.6 status: Active
claude-sonnet-4-6 remains Active. Its tentative retirement is no sooner than February 17, 2027 - a date that can move later, not a hard cutoff.
No forced migration
You can keep calling Sonnet 4.6 in production. Sonnet 5 is offered as the recommended upgrade, not a mandatory switch.
New tokenizer caveat
Sonnet 5 uses a new tokenizer: the same text uses ~30% more tokens than Sonnet 4.6, so $2/$10 is roughly cost-neutral versus 4.6's $3/$15 rather than a flat discount.
Positioning
On release (June 30, 2026) Anthropic slotted Sonnet 5 between Haiku 4.5 and Opus 4.8, describing its performance as close to Opus 4.8 at a roughly 40% lower price. As of 2026-09-29 the official model table attaches "the best combination of speed and intelligence" to Sonnet 5.5 (released 2026-09-28), and the newest Opus is Opus 5.5 (released 2026-09-22, $4 / $20); Opus 4.8 ($5 / $25) remains available.
