How to Use DeepSeek V4.1 Flash Free on Antseed

Looking for a free coding model you can try without handing over an email? DeepSeek V4.1 Flash is running free on Antseed right now, and there is no signup and no account setup standing in your way.

You get the model, a set of other free models to choose from, an OpenAI-compatible API, plus a desktop app and a CLI. That combination means it drops into the coding agent you already use.

Tutorial

1. Open https://antseed.com.
2. Download the desktop app or install the CLI.
3. Pick DeepSeek V4.1 Flash from the free models on offer. There are other free models on the same list if you want to compare.
4. Start using it with your own workflow or your coding agent. The API is OpenAI-compatible, so tools built for that format can point at it.

Wrapping Up

Nothing to sign up for, nothing to verify. Just install and test it against the work you are already doing.

One thing to keep in mind: free model availability and limits can change, so try it while it is up rather than saving it for later.
