BTL-4
Open-source agentic coding model based on Qwen3.5 MoE for autonomous development workflows
About
BTL-4 is an agentic coding agent built on Qwen3.5 Mixture-of-Experts architecture, specialized for tool use, code generation, and reasoning tasks. Designed for autonomous development workflows, it offers quantized variants (Q4_K_M, Q5_K_M, Q6_K, Q8_0) enabling efficient deployment on various hardware configurations. As an open-source alternative from Bad Theory Labs, it bridges the gap between large proprietary coding models and resource-constrained environments.
