Moonshot v1 8K

Retired

Legacy text model of the moonshot-v1 series. Release date and knowledge cutoff never published; cache-hit pricing was never specified for the v1 family. Confirmed RETIRED on 2026-08-31. Signal (first-party, stated as a consequence, not inferred): platform.kimi.ai/docs/models.md carries a warning block reading "The kimi-k2.5 and moonshot-v1 series were officially retired on August 31, 2026. Calls to these models now return a 404 (model not found) error. Please migrate to kimi-k3" — read 2026-09-02. Corroborated the same morning by Moonshot deleting this model's own pricing page: platform.kimi.ai/docs/pricing/chat-k25.md and chat-v1.md now 307-redirect onto the model list, which is why the citation below was repointed there. Until 2026-09-02 this row published status "ga", which was wrong from 2026-08-31 onward — nothing in this repo reads Moonshot, so the retirement went unseen for two days. Prices retained as the last published rates, read from platform.kimi.ai/docs/pricing/chat-v1.md on 2026-06-28 before Moonshot deleted that page. Moonshot names kimi-k3 as the migration target.
