The claude-sonnet-5 id is a pinned dateless snapshot with no -v1 suffix. QCode is an independent relay for Claude Code sessions and is not an official Anthropic first-party endpoint; it routes to Claude Sonnet 5 on your behalf.
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 the intro price is roughly cost-neutral versus 4.6's $3/$15 rather than a flat discount.
Positioning
Sonnet 5 is a mid-tier model slotted between Haiku 4.5 and Opus 4.8. Anthropic describes its performance as close to Opus 4.8 at roughly 40% lower price; Opus 4.8 ($5/$25) still leads the hardest coding and judgment tasks.
