LoongRL 7B
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

"We have made extensive efforts to ensure the reproducibility of our work. Details of the GRPO algorithm and hyperparameters are provided in Section 3.2.1 and Section 4.1. We provide our training prompt template in Appendix A.2. The datasets used in our experiments are described in Table 1. To further facilitate reproducibility, the supplementary materials include (i) our RL training code, (ii) the code for synthesizing KeyChain data, and (iii) several representative samples of the synthesized K…

What the numbers mean
Background
LoongRL 7B was published by Microsoft Research Asia,Shanghai Jiao Tong University,Carnegie Mellon University (CMU), in the country recorded as China, during October 2025. The category the publisher falls under is industry,Academia,Academia.
It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Quantitative reasoning.
Rather than being trained from scratch, it is derived from Qwen2.5 Instruct (7B). That is why it shares the base model's general shape and size.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
LoongRL 7B — common questions
LoongRL 7B— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
LoongRL 7B— how many parameters does it have?
It has a parameter count of 7B. 7B. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
LoongRL 7B— who created it?
It was published by Microsoft Research Asia,Shanghai Jiao Tong University,Carnegie Mellon University (CMU), based in China, an organisation categorised as industry,Academia,Academia.
LoongRL 7B— when was it released?
It was published in October 2025.
LoongRL 7B— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering, Quantitative reasoning. These are the areas it was designed around; they describe intent rather than a hard boundary.
LoongRL 7B— what GPU do I need to run it?
None. This is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
