About Relace: Relace Apply 3
Relace Apply 3 is a text model from Relace, released by the provider on 26 September 2025. It is a specialized code-patching LLM, which means its job is not to chat about code in general but to merge AI-suggested edits straight into your source files. It sits in the text category and is built around a single, focused task: taking proposed changes and applying them to the files you already have.
The model accepts text input and returns text output. It has a context window of 256,000 tokens and a maximum output of 128,000 tokens, so it can hold large files or multi-file diffs in a single request and still return a substantial patch. Supported request parameters are max_tokens, seed and stop. There are no image or audio modalities here; everything goes in and comes out as text.
The obvious use case is automated code editing. Because Relace Apply 3 applies updates from GPT-4o, Claude and other models into your files, it fits pipelines where one model proposes an edit and this model writes it into the codebase. That covers agentic coding tools, IDE assistants that need to commit suggested changes, batch refactors across many files, and review workflows where a proposed diff must be turned into a real modification. The large context window helps when the surrounding file or repository context matters for a correct merge.
You call it through api14's OpenAI-compatible API using the model id "relace/relace-apply-3". Because the endpoint follows the OpenAI chat completions shape, you can point an existing OpenAI client at api14 and pass that id as the model. Requests support max_tokens to cap the generated patch, seed for reproducible sampling, and stop to define where generation should halt. Input is plain text, so you supply the source content and the proposed edit as text in your messages.
Keep in mind that this is a specialized patching model rather than a general assistant. If your task is open-ended conversation, reasoning, or generating code from scratch, a general purpose model will usually fit better. Relace Apply 3 is at its best when the edit already exists and the remaining work is applying it accurately to your files.
