DeepSeek V4 Flash uses the April 0420 release reference, labelled in the chart and table. External results refer to the labelled source configurations, which may differ from AELDER’s configuration. They do not measure AELDER API speed or uptime. Source score markers (*) are preserved.
Why are 4 catalog models missing a score?
41 of 45 catalog models have a source reference on this index version. A missing result is not a zero score. These models remain in the catalog.
