ERNIE 5.1 vs Sonar

This comparison does not currently contain a protocol-matched coding benchmark for both ERNIE 5.1 and Sonar, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

ERNIE 5.1 is $4.00 and Sonar is $1.00 per million tokens, so Sonar is cheaper on this metric. ERNIE 5.1 is $18.00 and Sonar is $1.00 per million tokens, so Sonar is cheaper on this metric.

ERNIE 5.1 has the larger sourced context window. ERNIE 5.1 supports 131,072 tokens and Sonar supports 128,000 tokens.

There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.

Both models have the same sourced self-hosting status: unsupported. ERNIE 5.1 is not marked open weight; Sonar is not marked open weight.

ERNIE 5.1 is not documented with image input; Sonar is not documented with image input. This reflects supported input modalities, not vision quality.

ERNIE 5.1 has a sourced maximum output of 65,536 tokens; Sonar's maximum output is not reported. A larger limit cannot be determined.

ERNIE 5.1: reasoning and tool calling. Sonar: none of these features are definitively sourced. Feature support does not establish relative quality.

ERNIE 5.1 has 1 sourced provider route; Sonar has 2, so Sonar has broader tracked availability.

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
