jtregunna/cobrachicken-swe-1.2b
jtregunna/cobrachicken-swe-1.2b is a 1.2 billion parameter model fine-tuned from LiquidAI's LFM2.5-1.2B-Instruct. It functions as a specialized strategic concept router for software engineering tasks, identifying relevant concepts from a 518-entry knowledge base. This model synthesizes structured JSON guidance for downstream coding models, acting as a fast pre-processor to steer larger LLMs in code review, debugging, and architecture discussions.

Overview
jtregunna/cobrachicken-swe-1.2b is a 1.2 billion parameter model, fine-tuned from LiquidAI/LFM2.5-1.2B-Instruct, designed as a fast pre-processor for software engineering tasks. Its primary function is to analyze user coding requests and identify applicable strategic concepts from a 518-entry knowledge base. It then synthesizes structured JSON guidance, including concepts_applied, core_idea, key_principles, and avoid recommendations, to be injected into the prompt of a larger, downstream coding model.
Key Capabilities
- Strategic Concept Routing: Identifies relevant software engineering concepts for a given request.
- Structured JSON Output: Generates guidance in a consistent JSON format, making it machine-readable for other models.
- Fast Pre-processing: Optimized for low latency, achieving ~24 ms time to first token and ~231 tok/s decode throughput on an RTX A6000, enabling it to run efficiently before larger models.
- Specialized Guidance: Provides actionable
key_principlesandavoidwarnings tailored to the user's situation.
Intended Use Cases
- Pre-processing for Coding Models: Acts as a strategic steering layer for models like Claude, GPT, or Qwen Coder.
- Software Engineering Assistance: Useful for guiding code review, debugging, architectural discussions, and developer onboarding scenarios.
Limitations
- Null Discipline: Tends to route most inputs to some concept, even for off-topic requests.
- System Prompt Sensitivity: Requires a specific system prompt related to being a software strategist for optimal performance.
- English-only: Training data was exclusively English, and performance in other languages is untested and likely degraded.
- Not for General Chat: This model is highly specialized and will attempt to produce JSON for any input, even when free-form prose would be more appropriate.
