Where it's used

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: 2 quantized builds and 6 Spaces.

Will it fit?

Weights only, an estimate: leave room for the KV cache. Method

Fits a 16 GB card at INT4

About 1.3 GB at INT4, 2.7 GB at FP8, 5.3 GB at BF16: weights only, so leave room for the KV cache.

The story so far

Weights, every dated article, and repo commits on one rail.

4 repo commits since the weights landed

Teal is the weights (2026-09-26), grey ticks are repo commits.

What the card says

2 cited sentences

Summary generated, cited

Intern-Decision-2B is a 2.21B parameter multimodal structured decision model fine-tuned from Qwen/Qwen3.5-2B.[1][2] The model uses a Qwen3_5ForConditionalGeneration architecture to return an answer distribution for questions in one forward pass.[3][4]

Use-case evidence

7 use cases

What it is good at 7 use cases

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.
