Model Card
Morph V3 Large is Morph's high-accuracy code apply model, optimized for complex and precise code transformations. Like its faster sibling, it acts as the execution layer in agentic coding workflows — taking edit suggestions from reasoning models and merging them into existing code.
It achieves approximately 98% accuracy on code transformations at speeds around 4,500 tokens per second. The model supports a 262,144-token context window with up to 131,100 output tokens, allowing it to process entire codebases or large files in a single request.
Morph V3 Large is the better choice when edit correctness matters more than raw speed — particularly for production codebases or complex multi-file changes where a 2% accuracy gap can mean hundreds of broken edits at scale.
