Code Completion

Code completion is a key feature provided by Tabby in its IDEs/extensions. Tabby can analyze code repositories or documentation supplied by users and leverage them to generate helpful code suggestions.

Tabby also allows for more customized configurations by modifying the [completion] section in the config.toml file.

Input / Output

This configuration requires tuning of the model serving configuration as well (e.g., context length settings) and can vary significantly based on the model provider (e.g., llama.cpp, vLLM, TensorRT-LLM, etc). Therefore, please only modify these values after consulting with the model deployment vendor.

[completion]

# Maximum length of the input prompt, in UTF-8 characters. The default value is set to 1536.
max_input_length = 1536

# Maximum number of decoding tokens. The default value is set to 64.
max_decoding_tokens = 64

The default value is set conservatively to accommodate local GPUs and smaller LLMs.

Additional Language

Tabby supports several built-in programming languages. For more details, please refer to Programming Languages.

Users can manually configure additional programming languages by defining them in the config.toml file.

Below is an example of how to support Swift:
