Gemma 4 31B endpoint guide
13 of 14 Gemma 4 31B endpoints currently have the published data required for this ranking. Cerebras leads at 99.98% via cerebras/fp16. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.
The reliability ranking uses the published 30-minute endpoint uptime measurement. This short operational window can reveal current instability, but it is not a service-level agreement or a substitute for longer-term availability monitoring.
SambaNova currently ranks second at 99.96%. Compare that gap with input and output price, response-start time, output speed, 30-minute uptime, context length, and the exact route before deciding whether first place is meaningful for your workload.
Gemma 4 31B has 14 published provider options, and performance data is matched to each exact OpenRouter routing tag. Different quantization, context, regional deployment, or provider configuration can change price and behavior even when the underlying model name is identical.
