What this model can do through the Hostlinku gateway.
Vision
Reads images, screenshots, and diagrams alongside text. Send image inputs directly in the messages payload.
Function calling
The model calls tools you define and folds their results into the reply. Required for agentic workflows and multi-step automation.
Reasoning
Spends extra thinking tokens on hard problems before answering. Best for math, code, and multi-step logic.
Hostlinku measures this model from real request traffic: uptime and latency, not self-reported.
