Deep dive
The capability footprint differs most on vision: Grok 4.20 Multi-Agent, multimodal input: Grok 4.20 Multi-Agent, reasoning mode: Grok 4.20 Multi-Agent, function calling: Grok 4.20 Multi-Agent, tool use: Grok 4.20 Multi-Agent, and structured outputs: Grok 4.20 Multi-Agent. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Grok 4.20 Multi-Agent lists tiered pricing: 0-200,001t is $1.25/1M input and $2.50/1M output; 200,001t+ is $2.50/1M input and $5/1M output, while Kimi K2 Thinking Turbo lists $1.15/1M input and $8/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Grok 4.20 Multi-Agent lower by about $1.58 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 3 providers versus 1, so concentration risk also matters.
Choose Grok 4.20 Multi-Agent when reasoning depth, larger context windows, and broader provider choice are central to the workload. Choose Kimi K2 Thinking Turbo when provider fit and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which has a larger context window, Grok 4.20 Multi-Agent or Kimi K2 Thinking Turbo?
Grok 4.20 Multi-Agent supports 2m tokens, while Kimi K2 Thinking Turbo supports 262k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, Grok 4.20 Multi-Agent or Kimi K2 Thinking Turbo?
Grok 4.20 Multi-Agent lists tiered pricing: 0-200,001t is $1.25/1M input and $2.50/1M output; 200,001t+ is $2.50/1M input and $5/1M output. Kimi K2 Thinking Turbo lists $1.15/1M input and $8/1M output tokens on the cheapest tracked provider. Compare the tier you will actually use; cheap async pricing can overstate savings for interactive workflows. Provider discounts or batch pricing can still change the final bill.
