Best estimate from public evidence; the vendor did not disclose every value. Anthropic does not disclose parameter counts or architecture. The 50B dense entry is a low-confidence catalog estimate for the small, latency-oriented Haiku tier, not a vendor claim or a measured count. The cited announcement establishes the exact model identity, positioning and closed API availability. OpenRouter declares low, medium, high, xhigh and max effort levels with medium default and adaptive thinking.
