DeepSeek V4 Flash Returns 403 RegionError for Non-China Access via Third-Party Service
English summary
A user of the 'opencode go' subscription service received an HTTP 403 error when attempting to use DeepSeek V4 Flash. The error body is a RegionError stating that the latest version of the model is only available hosted in China and requires explicit opt-in. This indicates that DeepSeek has geo-restricted the V4 Flash model to Chinese IP addresses or accounts. The restriction affects non-China users even when using a third-party service that previously provided access. The situation may signal a change in DeepSeek's deployment policy for its latest models.
Chinese summary
一位“opencode go”订阅用户尝试使用 DeepSeek V4 Flash 时收到了 HTTP 403 错误。错误信息为 RegionError，指出该模型的最新版本仅在中国部署，需要主动选择加入。这表明 DeepSeek 已将 V4 Flash 模型的地理访问限制为仅限中国 IP 或账户。即使通过原先可用的第三方服务，非中国用户也会受到此限制的影响。这一情况可能反映了 DeepSeek 最新模型部署策略的变动。
