Hey Product Hunt,
I’m Dixshant, building Lumino AI.
We built Lumino because repeated-prompt LLM workloads can get expensive fast. AI tutors, legal document tools, RAG apps, support bots, and agents often send the same large context again and again.
Lumino gives builders OpenAI-compatible model APIs with cached input token accounting, so repeated-prefix usage is easier to test, track, and optimize.
In one repeated-prefix test:
First call: 3,066 prompt tokens, 0 cached, 51 paise
Repeat call: 3,066 prompt tokens, 3,040 cached, 12 paise
That is about 76% lower request cost on the repeat call.
Would love feedback from anyone building AI tutoring, legal AI, RAG, agents, or document-heavy LLM products.
How does the per-second GPU billing actually handle setup and teardown time, do you charge for that or only the inference itself?
The per-second GPU billing is a really thoughtful touch, especially paired with local currency pricing. Makes it way less intimidating to spin up a model for a quick test.
Renting a few H100s through Lumino was refreshingly painless — the per-second billing meant I didn't feel guilty spinning one up just to test a script, and paying in euros saved me the usual conversion math.
How does the per-second GPU billing actually work when spinning up something like an A100, and are there minimum charges or cool-down periods before I can shut it down?
How does the per-second GPU billing work when I'm running long training jobs - do idle minutes still get charged, or does it only count active compute time?
The per-second GPU billing paired with local currency pricing is a really thoughtful move, especially for teams outside the US who usually get burned by FX fees. Clean execution on something most competitors ignore.
