meraGPT

Small models.
Specific jobs.

A frontier model is an expensive way to do one narrow task. We serve small models trained for a single job each, over an OpenAI-compatible API, billed per token against prepaid credit.

  • Prompt Optimizer 1soonTurns a rough instruction into a prompt that works.
  • Query Refiner 1soonTurns a chatty question into a retrieval query.

Model details

Restyler 1

Available

Takes the response from any model, including Claude, Gemini, GPT and your own fine-tunes, and rewrites it so it reads the way a person writes. It is trained to hold on to facts, meaning, names, numbers, links and formatting — see the measured retention rates below. Built to sit at the end of a generation pipeline: cleaning up drafts, tightening documentation, and making machine-assembled copy readable.

Prompt Optimizer 1

soon

Turn a rough instruction into a clear, effective prompt.

prompt-optimizer-1

Query Refiner 1

soon

Turn a conversational question into a strong retrieval query.

query-refiner-1

Same API, same prepaid credit, same per-token billing. Model ids are already fixed, so code written against them will keep working. Rates for every model are in what it costs.

how it works

Getting started

  1. 01

    Add credit

    Ten dollars minimum, by card. It sits as a USD balance, not a token allowance or a plan tier. Optional auto top-up keeps it from running dry, with a monthly ceiling so it cannot surprise you.

  2. 02

    Create a key

    Name it, optionally restrict which models it may call and cap what it may spend. The secret is shown once. We store a hash, so nobody can read it back, including us.

  3. 03

    Call the API

    Point any OpenAI client at meragpt.com/v1 and change the model name, or use /v1/restyle, which takes a whole document and handles the splitting for you.

  4. 04

    Pay for tokens

    Metered per token against your balance, at the rate on the model card. Spend by day, by model and by key is on the dashboard. Stop calling and you stop paying.

pricing

What it costs

Credit is denominated in USD, not in an invented currency, so the balance on your dashboard is the amount of money you have left. Nothing expires on a monthly cycle and there is no seat count.

minimum

$10 to start. A thousand-word article costs roughly $0.0002 to restyle, so that covers tens of thousands of them.

auto top-up

Optional. You choose the trigger balance, the amount, and a monthly ceiling above which it stops and emails you instead.

free tier

The playground runs without an account, on a daily allowance. Signing in spends credit instead.

questions

Common questions

What is Restyler actually for?

Rewriting machine-written prose so it reads like a person wrote it, without changing what it says. Generated drafts, documentation, product copy assembled by a pipeline. It preserves facts, names, numbers, links and formatting; it is not a summariser and not a general-purpose rewriter.

How good is it, honestly?

On our held-out benchmark it keeps every fact in 41% of blocks and 73% of facts on average, with zero invented first-person voice and no repetition loops. That means roughly a quarter of blocks lose something, so it is not a substitute for review where accuracy is critical. The full numbers, including where it is weakest, are on the model page.

Is this an AI-detector bypass?

No, and we would rather you did not use it as one. It was trained for naturalness under strict semantic preservation; evasion was never an objective and is not measured. Detector scores move around with every detector release, so anyone selling you a guarantee there is selling you something they cannot deliver.

Why not just use a frontier model?

You can, and for a one-off it is fine. But asking a large model to do this specific job costs orders of magnitude more per token, and measured on preservation it does worse. Frontier models tend to compress, dropping content while producing text that reads well. A model trained for exactly this task is both cheaper and more faithful.

Is the API really OpenAI-compatible?

Yes for the wire format: point any OpenAI client at meragpt.com/v1, change the model name, and it works. Two honest caveats. Sampling parameters like temperature and top_p are accepted and ignored, because decoding is fixed at greedy and sampling measured worse. And streaming arrives a paragraph at a time rather than a token at a time.

What happens when my credit runs out?

Requests return a 402 with a message saying so, and nothing breaks silently. Auto top-up, if you enable it, charges your card when the balance falls below a level you pick. You can set a monthly ceiling, above which it stops and emails you instead of carrying on.

Do you train on what I send?

No. Requests are not used as training data. We record token counts, timing and cost for your usage dashboard and our billing; we do not retain the text of your requests or responses after serving them.

Can I get a refund on unused credit?

Email us and we will refund an unused balance. We would rather return it than have you sitting on credit you cannot use. The minimum exists to keep card fees sane, not to trap money.

What happened to the Hermes agent boxes?

That product ended on 2 September 2026 and existing subscriptions were closed out. meraGPT is now an API platform for small task-specific models. If you were a box customer and still need your data, email us.

Paste something you wrote

The playground runs the same model the API does, with no account and no card. Paste something you wrote with an LLM and see whether the output is worth paying for before you decide that it is.
