Hugging Face does not say who downloads a model or with what. These are the proxies: API providers listing it, quantized builds, fine-tunes/adapters/merges, and Spaces that load it.
No API provider serves it, so its downloads are people running it themselves: 5 Spaces.
Weights, every dated article, and repo commits on one rail.
Teal is the weights (2026-09-17), amber triangles are 1 dated article (each links to it), grey ticks are repo commits.
6 derivatives on the Hub. Which build to run, by runtime: the most downloaded in each class.
From the Hugging Face model tree; quantized builds in teal, fine-tunes, merges and adapters in greys.

NanoJev is a 0.6B decision model fine-tuned from the Qwen3-0.6B backbone.[1][2] The model returns action distributions for tasks including Maze, Snake, and ViZDoom Basic.[1] It utilizes a shared backbone with an attention-based Choice head to score candidate sets.[3]
Generated 2026-10-07 15:19 UTC by parasail-gemma-4-26b-a4b-it; each numeral points at the fact it rests on. Not a verdict.
Labels are evidence, not verdicts: measured a third-party leaderboard row for this model; author-reported a number the model author published in the card or eval files; structural a deterministic signal from the name, config or chat template, or a decision-model estimate. Each chip links to its source. All use cases.
