DeepSeek-NeoForge
DeepSeek-NeoForge lets players chat with the DeepSeek language model from inside a NeoForge 1.21.4 game, using a DeepSeek API key.
What it does
Once a player enters a DeepSeek API key in the common configuration file at config\deepseek-common.toml, the mod sends in-game messages to DeepSeek through its API and shows the replies in the chat. Players start a conversation with a command, and the mod keeps the exchange going until the conversation is ended.
Before the first use, the required fields in deepseek-common.toml must be filled in: the API key and the model to query. The model setting accepts deepseek-chat or deepseek-reasoner, and deepseek-chat is the default. Some optional values can be left at their defaults. Because the mod runs only on the server, players join without installing anything, and the server owner controls the key and model.
The mod is released under the MIT License and is open source. Its source code and issue tracker are public. It was first published on 2025-06-02, and the latest NeoForge file, 1.1.0 for 1.21.4, followed on 2025-06-03. Builds exist only for NeoForge and for Minecraft 1.21.4.
