Which is cheaper, ERNIE X1.1 or o3-pro?+
ERNIE X1.1 is $1.00 and o3-pro is $20.00 per million tokens, so ERNIE X1.1 is cheaper on this metric. ERNIE X1.1 is $4.00 and o3-pro is $80.00 per million tokens, so ERNIE X1.1 is cheaper on this metric.
Which has a larger context window, ERNIE X1.1 or o3-pro?+
o3-pro has the larger sourced context window. ERNIE X1.1 supports 66K and o3-pro supports 200K.
Which performs better in benchmarks, ERNIE X1.1 or o3-pro?+
There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.
Can ERNIE X1.1 or o3-pro be self-hosted?+
Both models have the same recorded self-hosting status: unsupported. ERNIE X1.1 is not marked open weight; o3-pro is not marked open weight.
Can ERNIE X1.1 and o3-pro understand images?+
ERNIE X1.1 is not documented with image input; o3-pro is documented with image input. This reflects supported input modalities, not vision quality.
Which can generate longer answers, ERNIE X1.1 or o3-pro?+
o3-pro has the larger sourced maximum output: ERNIE X1.1 supports 66K and o3-pro supports 100K output tokens.
Do ERNIE X1.1 and o3-pro support reasoning and tool use?+
ERNIE X1.1: reasoning and tool calling. o3-pro: reasoning, tool calling, and image input. Feature support does not establish relative quality.
Which is available from more inference providers, ERNIE X1.1 or o3-pro?+
ERNIE X1.1 has 1 sourced provider route; o3-pro has 2, so o3-pro has broader tracked availability.
Which offers better value, ERNIE X1.1 or o3-pro?+
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.
