Astral-4B-Coder

Astral 4B is the largest sized model in the Astral coder family. It was fine-tuned from Astral 4b on LucidityAI/Astral-Post-Training-Dataset.

Use /no_think for agentic tasks, use thinking for non-agentic coding tasks/

As with usual Qwen3 models, reasoning can be toggled through the usage of ``/no_think`` or not.
