What

What it is

Seti ndogo ya sheria zinazoweka mipaka ya matumizi na kulinda bajeti. Inachanganya kikomo cha gharama na rate limits ili mtumiaji mmoja asichome bajeti.

What it is not

Si mfumo kamili wa fedha wala mbadala wa mkakati wa bei. Ni safu ya ulinzi kwa bidhaa za hatua za mwanzo.

2-minute theory

Gharama za AI zinaweza kukua haraka kwa matumizi makubwa.
Rate limits hulinda uthabiti na bajeti kwa pamoja.
Vikomo wazi hufanya majaribio ya bei kuwa salama.

Key terms

Rate limit: Sheria ya kuzuia idadi ya requests kwa mtumiaji au muda.
Cost cap: Kiasi cha juu unachokubali kutumia kwa kipindi.

Gharama zinatabirika
Outages chache
Udhibiti bora wa matumizi ya bure

Risks of ignoring

Bili za kushangaza
Matumizi mabaya na heavy users

How

Step-by-step method

Chagua kikomo cha gharama za mwezi.
Fafanua rate limits kwa kila mtumiaji.
Ongeza kikomo cha kila siku kwa watumiaji wa bure.
Weka alerts kwa spikes.
Pitia matumizi kila wiki.

Do and don't

Anza na limits za tahadhari
Rekodi matumizi kwa mtumiaji

Don't

Toa matumizi ya bure bila controls
Kusubiri bili ndipo uanze kuchukua hatua

Common mistakes and fixes

Mistake: Hakuna cost cap. Fix: Weka kikomo kidogo cha mwezi.
