Best estimate from public evidence; the vendor did not disclose every value. API-only exact checkpoint on the research date. Moonshot says the full weights will be released by November 4; do not classify promised weights as available. Total and active parameter values are estimates inherited from the Kimi K3 backbone because the official Pro blog describes a post-trained K3 without restating exact counts. Native K3.1 Pro documentation requires thinking with low/high/max, which are the benchmarked modes. On the research date, the standard endpoint is $2/$10 per million; the same model has a faster $4/$20 endpoint. These benchmarks use standard speed.
