Estimate your cost

Set your usage. Your estimate updates as you type.

Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.

One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

Quick take

Kimi K3

Moonshot AI's frontier multimodal model for million-token coding, reasoning, knowledge work, and tool-driven agents.

Best for

  • Large codebase and document work
  • Agents that repeatedly reuse a long context
  • Multimodal reasoning through a direct or gateway API

Watch out for

Moonshot's public terms permit broad service-improvement uses of submitted content. Treat the provider route and enterprise agreement as a core requirement for confidential work.

NVIDIA Nemotron 3.5 Lightning

NVIDIA's compact 30B mixture-of-experts model for efficient specialist agents and high-volume text workflows.

Best for

  • High-volume agent sub-tasks
  • Efficient self-hosted reasoning
  • Long-context RAG and instruction workflows

Watch out for

The current release is labeled preview. Validate the exact precision, language, tool template, provider route, and long-context memory needs before standardizing a production fleet.
