Hiveku Builder offers three AI model tiers. Each tier balances speed, capability, and cost differently so you can pick the right one for the task at hand.

​
Model tiers

​
When to use each tier

Mini is the right default for:
  • Renaming variables, fixing a typo, tweaking copy
  • Quick “what does this function do?” questions
  • Small CSS / styling adjustments
Max is the right default for:
  • Building a new feature across a few files
  • Debugging an issue with specific reproduction steps
  • Adding a new page, component, API route
  • Refactors that touch 2-5 files
  • Most everyday coding work
Ultra is worth reaching for when:
  • A refactor will touch many files and the reasoning needs to stay coherent across the entire change
  • Architecture decisions where the tradeoffs need careful weighing across multiple options
  • Deep debugging where the cause may be several layers removed from the symptom
  • Large parallel exploration (“find every place we use X, understand the pattern, propose a unified replacement”)
A useful test: if your task feels like “this is going to take an hour of my undivided focus to think through carefully”, it’s probably an Ultra task. If it feels like “I know what to do, I just need help executing it”, Max is plenty.

​
Reasoning effort

Each model tier supports three reasoning effort levels:
  • Low — minimal thinking, fastest responses
  • Medium — balanced depth and speed (default)
  • High — deep analysis, slower but more thorough
Higher reasoning effort consumes more credits per message on the Max and Ultra tiers.

​
Switching models

Select your model tier from the dropdown in the chat panel toolbar. The change takes effect on the next message you send.
You can switch models mid-conversation. The AI retains the full context of your chat regardless of which model you use. A common pattern: explore and design on Ultra, then switch to Max to execute the plan once direction is clear.

​
Credit consumption

  • Mini — free on all plans, no credit deduction
  • Max — deducts credits based on message complexity and reasoning effort
  • Ultra — deducts credits at a higher rate, reflecting the more powerful model
