Solar Pro 3 endpoint guide

How to interpret the Fastest First-Token Solar Pro 3 Inference Providers

1 of 1 Solar Pro 3 endpoint currently have the published data required for this ranking. Upstage leads at 0.84 s via upstage. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.

How response-start time is ranked

The first-token ranking orders endpoints by the recent median time before output begins. This is useful for interactive applications, but it should be read alongside throughput because the first provider to start is not always the first to finish a long answer.

Compare Upstage with the next option

Only 1 route currently qualifies, so the rank alone provides limited choice. Review every visible endpoint for price, speed, uptime, context length, and route-specific configuration.

Use the route, not only the provider name

Solar Pro 3 has 1 published provider option, 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.
