Hemlock-Qwen3.6-27B is a 27 billion parameter instruction-tuned model developed by nbeerbower, based on the Qwen3.6 architecture. It is specifically designed to function as an operator model capable of writing Hemlock code, a capability achieved by merging the Schierling adapter into the Vorarbeiter base. This model excels at Hemlock code generation and delegation of non-Hemlock engineering tasks, making it suitable for specialized code agent applications.

Model Overview

Hemlock-Qwen3.6-27B is a 27 billion parameter model developed by nbeerbower, combining the Vorarbeiter base with the Schierling adapter. This integration enables the model to act as an operator capable of generating Hemlock code, a unique feature as most code agents do not understand Hemlock. The model maintains the operator behavior of delegating non-Hemlock engineering work to other coding agents and provides factual answers on topics that the base model might otherwise sanitize.

Key Capabilities

  • Hemlock Code Generation: Achieves 65.0% on the hembench evaluation (up from 10.1% in the base model), with 22 tasks fixed and 0 broken, and a significant reduction in non-executable generated code.
  • Operator Behavior: Retains the ability to delegate non-Hemlock engineering tasks, inherited from the Vorarbeiter base.
  • Tool Use: While this specific model does not include the egirl-specific tool schema, its lineage (Wichtel) demonstrates strong tool use (47/47) and delegation (10/10) when that adapter is added.

Good For

  • Hemlock Language Development: Ideal for applications requiring the generation and understanding of Hemlock code.
  • Specialized Code Agents: Suitable for agents that need to handle Hemlock-specific tasks while delegating other programming languages to external tools.
  • Intermediate Agent Development: Provides Hemlock capabilities without baking in specific tool schemas, allowing for custom tool integration.
