Moonshot AI’s Kimi family has expanded fast. Chat-O now offers five Kimi models spanning the Balanced and Power tiers, from lightweight daily drivers to a 2.8T-parameter flagship. Here’s the full lineup.

The Kimi models on Chat-O

Model Tier Context Focus
Kimi K2 Balanced 200K General coding, syntax debugging, API integration
Kimi K2 Thinking Power 200K Reasoning-heavy tasks with visible chain-of-thought
Kimi K2.5 Balanced 256K General coding, code generation, multimodal tasks
Kimi K2.5 Thinking Power 256K Reasoning, code generation, complex problem solving
Kimi K2.6 Balanced 256K Long-horizon coding, multi-agent orchestration
Kimi K2.7 Code Balanced 256K End-to-end programming over long contexts
Kimi K3 Power 1M Complex coding, knowledge work, agentic workflows

Which Kimi should you pick?

For everyday coding (Balanced tier)

  • K2.7 Code if your task is end-to-end programming over a long context
  • K2.6 if you’re orchestrating multiple agents or long coding sessions
  • K2.5 if you want a balanced multimodal daily driver

For heavy reasoning (Power tier)

  • K2.5 Thinking for visible chain-of-thought reasoning on complex problems
  • K2 Thinking for older reasoning workloads (still available)
  • K3 when you need the 1M context window and 2.8T-parameter depth

Why so many Kimi models?

Each Kimi release sharpened a different edge:

  • K2 introduced strong general coding at a Balanced price.
  • K2 Thinking brought visible reasoning to the Power tier.
  • K2.5 added multimodal capabilities and a 256K context.
  • K2.6 pushed into long-horizon coding and multi-agent orchestration.
  • K2.7 Code specialized further for end-to-end programming tasks.
  • K3 jumped to a 2.8T-parameter open-weight multimodal flagship with a 1M context.

Keeping all of them available means you can pick the cheapest model that gets the job done rather than over- or under-shooting.
