💡 1. Base Model, Training Stack & Collaboration

📖 2. Background & Motivation

This model integrates:

Agent Traces (lambda/hermes-agent-reasoning-traces): Each sample contains real multi-turn tool execution results (not fabricated outputs), with step-by-step reasoning inside <think> tags. Coverage includes:

📊 3. Performance Benchmarks

🗺️ 4. Training & Data Pipeline Overview

The training process fuses Trace Inversion data augmentation with a Three-Stage Curriculum Learning pipeline. The core engineering focuses on expanding context length gradually while training on reconstructed reasoning traces and real agent trajectories to keep the output format stable.

[!NOTE] Due to the complex and diverse format of agent trajectory datasets, rigorous cleaning and format standardization were applied to ensure data quality.

📚 5. Three-Stage Curriculum Learning

To steadily scale reasoning quality under long-context inference, Qwopus-3.6-27B-Coder uses a curriculum-style data mixture building on the approach proven in the Qwopus coder line. The model is first stabilized on short, clean reasoning samples, then exposed to complex coding and agent traces, and finally reinforced with longer contexts plus replay data.

🎯 6. Recommended Use Cases & Known Limits

[!CAUTION] Deployment note: The model may emit reasoning inside <think> and </think> tags. Front-end applications and agent frameworks should parse or hide these sections where appropriate. For tool calling, ensure the prompt format and system prompt match the training data configuration to activate agent capabilities.

⚠️ 7. Training & Deployment Notes

[!CAUTION] Compatibility Notes

Tool Calling Format: To activate the model's agent capabilities, ensure the prompt format and system prompt include appropriate tool definitions and match the training data format.

Reasoning Output Extraction: The model's thinking process is wrapped in <think> and </think> tags. Front-end applications may need to parse and hide these tags.

Long-Context Usage: For contexts beyond 32K, consider enabling RoPE/YaRN scaling (e.g., --rope-scaling yarn --rope-scale 4 --yarn-orig-ctx 32768 in llama.cpp).

📋 8. Benchmark Progress

The first completed evaluation is the no-thinking SWE-bench Verified run reported above. Additional local agentic benchmarks remain pending and will be added after testing.
