Savings result
Quality upgrade at similar cost - complex queries get frontier-model answers while simple queries stay on the cheapest option

Usage starts-to-finish

Example: Product support workload

If your team sends 20 support messages a day in Chat mode, the minimum reserve is around 600 credits each month (starts at 1 reserve credit/request). Final usage settles by model and token volume.

$9.00/mo with Gemini 3 Flash ($3.00 input + $6.00 output)

Gemini 3 Flash is already the cheapest frontier model, so the optimization play is different here. Instead of saving money, use auto-routing to improve quality: let LLMWise send complex reasoning queries to Claude Sonnet or GPT-5.2 while keeping straightforward requests on Flash. The blended cost is still dramatically cheaper than using a frontier model for everything, and the quality on hard queries improves significantly.

Common questions

How much does Gemini 3 Flash cost per token?
At $0.10 per million input tokens and $0.40 per million output tokens, Gemini Flash is borderline free for most workloads. A 1,000-token message costs $0.0005. For 100K messages/month, your total bill is $50. The same volume on GPT-5.2 runs $1,500.
Is there a free tier for Gemini Flash?
Yes. Google AI Studio offers a free tier with up to 60 requests per minute for Gemini Flash. This is sufficient for prototyping and small-scale testing. For production usage, you will need a paid Google Cloud account. LLMWise also offers 20 free credits that cover Gemini Flash and every other model.
What is the cheapest AI model in 2026?
Gemini 3 Flash at $0.10/$0.40 per million tokens is the cheapest frontier model. DeepSeek V3 at $0.14/$0.28 is slightly cheaper on output but is not as widely available. Both are dramatically cheaper than GPT-5.2 or Claude Sonnet while delivering strong performance on most tasks.
How does Gemini Flash pricing compare to GPT-5.2?
Gemini Flash is 30x cheaper on input ($0.10 vs $3.00 per million) and 30x cheaper on output ($0.40 vs $12.00). For high-volume applications, this difference is massive - a workload costing $900/mo on GPT-5.2 would cost roughly $30/mo on Gemini Flash. The quality gap depends on your task; Flash is weaker on complex reasoning but excellent for classification, extraction, and simple Q&A.
