Kev 4B r10 is an open-weights decision model from Jared Palmer, released 24 September 2026. Its published size is 4.66B parameters. Licence: apache-2.0.
Catalogue identity notes
Exact Decision Index tested engine kev-4b-r10; reported model Kev 4B r10. Type: LoRA + head; 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: kev:4b, manifest c0e732655dc9d799dd21ba7f2f9a445fbd50ee83578e96ccfbf691c1be9dde53, matching the independent accuracy-run manifest. Native family implementation; published runtime precision label F32. Memory is measured peak GPU increase (11200 MiB, rounded upward to 11.0 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.
