Why did the same question cost different amounts twice?

Each call is billed for its own tokens:

• Different answer length — the model doesn't write the same number of tokens each time.
• Thinking varies — Max and Heavy may reason more on one attempt.
• More context — later messages include the whole chat so far as input.
• Different tier — auto may route differently.

The usage field shows exactly what each call used.

Good to know#

• Flash $1.60/$3.40, Max $1.80/$3.80, Heavy $2.00/$4.40 per 1M tokens in/out.
• Logs shows the cost of every metered request.
• Plans cover app usage (Line CLI, Cosmos Agent, Telegram); credits pay for the Model API and Agent API on every plan.
