Summary

Malibu 2.1 is an incremental release, from Malibu v2.0, that builds on Malibu v2’s major improvements in code editing, question answering, and assistant capabilities with a number of new features.

​
Improvements

Major changes or improvements include:
  • Code editing: Malibu 2.1 was trained on an expanded set of RLCEF tasks, leading to better downstream performance at generating code edits that solve real world problems.
  • Instruction following: Malibu 2.1 went through extensive training to understand and follow user instructions more accurately, especially over the course of long conversations.
  • .poolside support: Malibu 2.1 was trained to understand and follow high-level formatting and structure instructions in the form of .poolside contents. See the .poolside reference for more details.
  • Multi-turn and long-context performance: Malibu v2 would sometimes fail to generate high-quality edits in longer conversations, and suffer from degraded performance with lots of files added to its context. Malibu 2.1 addresses these limitations, and should perform better in these scenarios.
  • Agent mode improvements: Malibu 2.1 comes with improved tool calling abilities, which means its accuracy at generating Agent mode commands is improved over v2, allowing it to more accurately search for files.
