I am opening thiss discussion to hear your personal favourite AI for your Tasks.
Let me start: For coding i currently most often use:
QWEN 3 (https://chat.qwen.ai/)Not only because its free, but it beats Google Gemini 2.5 and even Grok in difficult coding tasks.
For automated local Tasks i use:
or Magistral from Mistral AI.
These KI's run local and are strong enough for limited clearly defined coding tasks anyway.
