GLM 5.3 Flash vs Kimi K3 for heavy coding — which subscription would you choose?
A user is seeking advice on AI subscriptions for heavy coding, intending to primarily use GLM 5.3 Flash (80%) and Kimi K3 (20%) for harder tasks. Their main priorities are large projects, debugging, refactoring, agentic coding, and value for money. They are asking if this combination is optimal or if they should consider alternatives like Codex/GPT, Claude Code, or Gemini within the same budget.

I'm planning to use AI seriously for coding, roughly 80% GLM 5.3 Flash and 20% Kimi K3 for harder tasks.
I mainly care about large projects, debugging, refactoring, agentic coding and value for money.
Would you recommend this combination, or would I be better off spending the same budget on Codex/GPT, Claude Code, Gemini, or another model?
