Model Card for Bleenk

Model Summary

Bleenk 123B is an agentic large language model developed by Robi Labs for advanced software engineering tasks. The model is optimized for tool-driven workflows, large-scale codebase exploration, coordinated multi-file editing, and powering autonomous and semi-autonomous software engineering agents.

Bleenk is designed for long-horizon reasoning and real-world engineering environments rather than single-turn code generation.

Uses

Direct Use

• Software engineering agents
• AI-powered code assistants
• Codebase navigation and analysis
• Multi-file refactoring and maintenance
• Tool-augmented development workflows

Downstream Use

• Fine-tuning for organization-specific codebases
• Integration into internal developer platforms
• Agent frameworks for autonomous engineering

Out-of-Scope Use

• General-purpose chat or conversational agents
• High-risk decision-making without human oversight
• Tasks requiring domain-specific legal, medical, or financial guarantees

Bias, Risks, and Limitations

• The model may produce incorrect or incomplete code without verification
• Tool misuse may result in unintended system changes
• Performance depends on tool availability and prompt quality
• Trained primarily on publicly available and licensed data, which may encode historical biases

Recommendations

Users should employ strong sandboxing, testing, and human-in-the-loop review when deploying Bleenk in production environments.
