What programming languages do you support?

We support multiple code LLMs, each of them has been trained on different programming languages.

Our own model Refact 1.6B has been trained and works best for the following languages (alphabetical order): Bash, C#, C++, D, Golang, Java, JavaScript, Julia, Lua, Perl, PHP, Python, R, Racket, Ruby, Rust, Scala, Swift, TypeScript. Even if the model has not been specifically trained on a particular coding language, it can still make useful suggestions for code in that language.

What models are under the hood?

We use a combination of our own models and 3rd party models for different functions.

Our own model is Refact 1.6B code LLM. It’s State-of-the-art for the size and In addition to regular prompting, this model can infill code in the middle and produce changes to the code by following instructions. Check it out

For chat we use models from the GPT family, you have the option to opt-out of them.
In the self-hosted version we also have StarCoder, Code Llama and WizardCoder models.

For a full list of our supported models and their functionality, check our docs.
