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.
Prompt caching
Response schema
Guarantees JSON output that matches a schema you provide. No brittle post-parsing on your side.
Streaming
Streams tokens as they are generated for real-time UX. Supported on every Hostlinku protocol.
Web search
Runs server-side web searches and folds the results into the answer. Billed per 1K calls.
Audio
Video
File input
Accepts documents such as PDFs and spreadsheets as context. Great for Q&A over long attachments.

Hostlinku measures this model from real request traffic: uptime and latency, not self-reported.

37 requests in 7 days, 0 failed · automatic failover to backup channels
Latency and uptime are measured from real request traffic over the last 7 days; throughput from user output.
Swap the base URL and everything else stays the same. Native protocols pass through; adapted protocols are translated by the Hostlinku gateway.
