How reliable is each host behind MythoMax 13B?

The cheapest offer is not a bargain if it is down. OpenRouter routes traffic to several upstream hosts for this model and publishes the availability its own router recorded over the last day for each of them. Least reliable first.

HostAvailability, last day Observed
nextbit/int4 99.98 % 16 September 2026
deepinfra/fp16 100.00 % 29 October 2026
mancer/fp8 100.00 % 29 October 2026
parasail/fp16 100.00 % 29 October 2026

This is availability as OpenRouter's router observed it, not as you would measure it calling the host directly: the network path is not the same. We read it once a day and keep every reading, so a host that was unreliable last August can still be shown to have been unreliable last August.

We publish no time to first token and no throughput. OpenRouter's API carries fields for both and leaves them empty on every endpoint we have read, and we will not fill a number the source does not give.

Where these figures come from

Source: OpenRouter. Every figure on this page was read from OpenRouter's own published price list, and every row above links straight back to it. We publish factual values with attribution, we do not reproduce OpenRouter's content, and we send readers to them. If you publish this source and want us to stop tracking it, write to contact@bertrande.com and we will act on it without argument.

How is this page verified?

Every figure above comes from OpenRouter's own published price list, which we rank as a level 1 source. We re-check it every 6 hours. Each observation stores the exact source URL and a SHA-256 fingerprint of the source content at that moment, which is what lets us prove what the source said on a given day.

The Proof column shows the first twelve characters of the SHA-256 fingerprint of the source content at the moment we read it. Hover it for the full value. It is what lets us demonstrate later what the source said on a given day, after that page has changed or vanished. The full fingerprints are in data.json.

No value on this page was produced, estimated or completed by a language model. Where we do not have a verified figure, the row is absent rather than filled in. Read the full methodology, or report an error.

Take the data, or watch this page

This page is available as data.json (including the full observation history of every parameter) and data.csv, under CC-BY-4.0, free, with attribution. See all downloads.

Want to know when this changes? Point a feed reader or a script at the Atom feed, which carries every confirmed change and is rebuilt hourly, or poll this page's data.json, where every figure carries its observation date and the fingerprint of its source. Both work today and need no address.
