whatmodel.sh / decision / vLLM-SR d3-nano (2B)

vLLM-SR d3-nano (2B) is an open-weights decision model from vLLM Semantic Router. Its published size is 2.21B parameters. Licence: apache-2.0.

Catalogue identity notes

Exact Decision Index tested engine vllm-sr-d3-nano; reported model vLLM-SR d3-nano (2B). Type: full fine-tune; technique: autoregressive. No API price or speed inferred from the benchmark. Current repository metadata checked separately; an unpinned alias is not evidence that today’s weights reproduce this historical run. Reviewed Ollaya local route added 2026-10-31: d3:nano, manifest 137bd4f1edd15d843102431d9b4ed066e581549fc3a5e61f72e6d09a28519ecf, matching the independent accuracy-run manifest. Native family implementation; published runtime precision label F32. Memory is measured peak GPU increase (8363 MiB, rounded upward to 8.2 GiB) on RTX 5090 during the short five-question triage workload, not download size or a maximum-context guarantee. Runtime installation is required; no fresh execution performed here. Historical benchmark adapter and input protocol still vary by result.
