# Model reference: DeepSeek-V4.1-Flash-1017: Wish-Driven Programming Made Real

Upstream release context and its relationship to DarkSeek availability.

## Reference release

The corresponding upstream page is https://api-docs.deepseek.com/news/news261017/. This is a reference to the upstream project, not an announcement that DarkSeek trained, released or serves that model.

## DarkSeek availability

Only the configured model registry and verified capability matrix describe the deployed DarkSeek service. An upstream model release does not automatically change account pricing, model ids, token limits, vision support or API behavior.

## Migration checklist

Before changing clients, verify model discovery, known-answer generation, streaming, tools, cancellation and output limits against the intended DarkSeek endpoint. Keep the previous configuration available for rollback. Upstream account balances, subscriptions and credentials do not transfer.
