}'Why Gemini 3.5 Fast
Coding Plan eligible
Spend Coding Plan credits on Gemini 3.5 Fast alongside Claude Opus, Sonnet, and GPT-5.5 — one prepaid pool, one API key.
Built for latency and volume
Sub-second first token — best for quick code review, chat, test generation, and iterative agent loops.
40% off official pricing
$0.90 input / $5.40 output per million tokens vs Google official $1.50 / $9.00. A flat 40% off, no tiers.
Which credits get consumed?
One API key works for both. Routing is decided by the model you call, not by the key.
Claude, GPT, and Gemini coding models spend the same Hypereal Credits wallet. Your selected top-up amount can reduce charges on these coding models.
Video, image, audio, 3D, GPU, training, and other model APIs use the prices shown on their product pages.
Frequently asked questions
Is Gemini 3.5 Fast included in the Coding Plan?
Yes. It is eligible for Coding Plan credits, so prepaid coding credits spend on it just like Claude Opus, Sonnet, and GPT-5.5.
What is the model ID?
Use gemini-3.5-fast in chat, /v1/chat/completions, and any OpenAI-compatible SDK call.
When should I use Fast instead of Thinking?
Use Fast for latency-sensitive coding loops, tests, and chat. Use Thinking for deeper review or multi-step reasoning. Both cost the same per token.
