Our take
Written Sep 1, 2026ReMM SLERP is a 13-billion-parameter text model released in 2023 under a non-commercial licence. It offers low-cost experimentation for hobbyists and researchers, though no benchmark scores verify its quality and its licence blocks most practical deployment.
Pick this for low-cost experimentation with small downloadable models where non-commercial use is acceptable, or budget text-generation tasks that stay inside the licence. Skip it if you need commercial use, measured quality data, or support for images, audio or video.
The case for it
- Lowest input price among its three tracked hosts.
- Fastest measured throughput among hosts with disclosed speed, at 46 tokens per second.
The case against it
- No measured quality scores — chat, reasoning, coding and other capabilities are all unverified.
- Non-commercial licence prohibits most product integration and many research applications.
- Text-only with a 6,144-token request limit, narrow by current standards.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
Can you run it yourself?
Comfortable fit
GeForce RTX 4090 · 24 GB
Room to spare. 11.5 GB spare means a 10% error in the size would not change the answer.
GeForce RTX 5090 · 32 GB
Room to spare. 19.5 GB spare means a 10% error in the size would not change the answer.
Apple M1 (8-core GPU) · 16 GB
Borderline fit on an estimated size. It leaves 0.7 GB spare on a size we calculated rather than measured, and a 10% error either way would change the answer.

Across the 3 listings we hold: 2 say they do not train on prompts, 0 say they do and 1 does not say. 2 appear in the zero-retention registry we check; the rest are unknown to us.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
- No independent board has scored it, so we hold no quality figures at all.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 1 of 3 listings does not say whether it trains on prompts.
- We hold no cached-input rate for any of its listings.
- We hold no batch or off-peak rate for any of its listings.
- We hold a decode speed for it, but no prompt-processing (prefill) figure, so how long the input side of a job takes is unknown to us.
