Honest notes

  • Token price is not task price: a model that needs fewer tokens per answer can cost less overall even with a higher per-token rate. Test with your own workload, not just this table.
  • Argon's headline advantage is the introductory window. After November 30, 2026, it costs $4/$20 \u2014 still cheaper than GPT-6 Astra and Claude Fable 5.1, but the gap narrows.
  • Thinking tokens are billed as output tokens, so agentic workloads with heavy reasoning cost more than the output slider alone suggests. Tunable thinking levels (low, medium, high) are your main lever.

It estimates your monthly API bill for Gemini 4 Argon from your input and output token volumes and cache hit rate, at both the introductory pricing ($2 per million input, $10 per million output tokens, until November 30, 2026) and the standard pricing that follows ($4/$20). It ranks Argon against GPT-6 Astra, Claude Fable 5.1, and Grok 4.7 at the same volume so you can see the cheapest option instantly.
