SenseNova-Loop-9B-Preview

by SenseTime (SenseNova) Open-weight model in Open-weight models

SenseTime, listed on the Stock Exchange of Hong Kong · sensetime.com · who's behind it

SenseNova-Loop-9B-Preview is SenseTime's open-weight multimodal model of about 9B parameters. It runs 24 of its 32 decoder layers twice, with text and images in, tool calling, a thinking switch and a 256K context. Apache 2.0. No released runtime loads it.

Best for Researchers who want to study or fine-tune a looped transformer, more than agents that need a model to call today

Trained by SenseTime (SenseNova), in the SenseNova-Loop family all its cousins

Assessment. An unusual architecture under Apache 2.0, with a 256K training context, a thinking switch and tool calling in the template. It's a preview in practice too: no released runtime runs it, loading it runs the repository's code, the files are twice the size the card implies, and nobody from SenseNova has answered a question yet.

From our research 12 facts checked against the vendor's pages

Surface graded: The open weights at huggingface.co/sensenova/SenseNova-Loop-9B-Preview, read from the model card, the files and their metadata, the config, the chat template, the commit history, the README and LICENSE of the GitHub repository and the runtimes' own code at their latest releases on 10 November 2026. Who SenseNova is comes from SenseTime's home, about and investor pages. The repository's model code, the training guides and the two pull requests weren't read. Nothing was downloaded or run
Model: 9,656,250,480 parameters in the files. The card says about 9B in total and about 14.6B at inference, since layers 4 to 27 of its 32 decoder layers run twice with shared weights. SenseNovaLoopForConditionalGeneration, with linear and full attention interleaved and two residual streams in the looped section. The config's text and vision parts carry Qwen 3.5's type names
Files: Eight safetensors shards (37.65 GB) and mtp.safetensors (0.49 GB) for multi-token prediction, chat_template.jinja, config, processor and tokenizer files, and modeling_sensenova_loop.py, the model's own code. No pickle files. Hugging Face lists a SHA-256 for the large files
Licence: Apache 2.0 in the card's metadata, and the card links the LICENSE in the GitHub repository. The model repository has no LICENSE file of its own
Runtimes: Transformers 5.18.0 with trust_remote_code, per the card. vLLM and SGLang only from open pull requests (vLLM 64832, SGLang 47281), and LightLLM, a server from ModelTC, on four GPUs. Released vLLM 0.33.0, SGLang 0.5.23, Transformers 5.22.2 and llama.cpp b12242 have no sensenova_loop code
Context: Up to 262,144 tokens in training, per the card's specification table
Hardware: No memory figure on the card. Its Transformers example uses one GPU, and its vLLM and LightLLM examples four
Training data: One sentence: the documented recipes combine long sequences, multimodal inputs and supervised task trajectories. No sources, sizes or cut-off, and the technical report is marked TBD
Languages: English and Chinese, per the card's metadata
Tool calling: The chat template carries a tools block and writes calls as tool_call blocks with function and parameter tags. The card says the training recipes include tool trajectories and gives no tool-calling example or parser
Reasoning: A thinking mode set with enable_thinking in the chat template call, off in the card's example. The template wraps reasoning in think tags
Recommended settings: The card's example uses greedy decoding. generation_config.json sets temperature 1.0 and top_p 0.95

Strengths

Apache 2.0, ungated
A 256K training context, stated on the card
Thinking can be switched per request
The architecture and parameter counts are documented
Changed in the last ten days

Weaknesses

No released runtime runs it. vLLM and SGLang need unmerged pull requests
Loading it runs Python from the repository
The files are 38.1 GB, mostly F32, though the card says BF16
No quantised build
No tool-calling documentation beyond the template
No limitations, safety results or data sources, and the technical report isn't out
None of 5 questions answered

Before you call it notes for agents

Read modeling_sensenova_loop.py before you load it. trust_remote_code runs it
Pin transformers 5.18.0, the version the card checked
Load with dtype=torch.bfloat16 as the card does, or the 38 GB of F32 weights stay at full size
Pass enable_thinking=False to apply_chat_template for a direct answer
Tool calls come back as tool_call blocks with function and parameter tags. Parse them yourself, since no runtime ships a parser
Wait for the vLLM or SGLang pull request to land in a release before putting it behind an API

Terms and privacy, as read

Terms of service not read yet

TL;DR Not read by us yet, so nothing here is checked. The document is published and scores 4 of 10 until we read it.

The document

Privacy policy none to read

TL;DR Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

The card names SenseNova only. SenseTime's site presents SenseNova as its foundation model series, and that is the tie between the two; the site wasn't read for a link to this repository.

The domain's registration date wasn't looked up.

Nothing is hosted under this listing, so Apache 2.0 stands in for terms of service and no privacy policy is scored.

www.sensetime.com has no security.txt (404 on 10 November 2026). Its about page gives a security contact.

Structured output 0, Nothing on the card about JSON or schema-constrained output. Reasoning control 10, the card documents enable_thinking in the chat template call, on or off per request, and the template puts the reasoning in think tags ahead of the answer. Context 10, 262,144 tokens in training, per the card's specification table, and config.json gives the language model 262,144 positions. 20 + 10 + 10 + 0 + 10 + 10 = 60.

Training data 5, one general sentence on the recipes, with no sources, sizes or cut-off. Last change 20, the last commit, on 2 November 2026, reworked the speculative decoding section of the card, 8 days before this check. Responsiveness 0, none of the 5 discussions that aren't pull requests (30 October to 9 November 2026) has a reply from a sensenova member, counted on 10 November by author flags and dates with a script, text not read.

Graded 46.8 D methodology v0.7

Fix list 15 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on SenseNova-Loop-9B-Preview. A fix counts at the next check, once it's public.

What we couldn't check

File health is 0 because the card says BF16 and the files are mostly F32. If SenseNova re-exports or corrects the card, the line moves to 10
Memory reads the 38.14 GB on disk. Loaded as BF16 it would sit in the 24 GB band
Runtimes is 0 with Transformers not credited, since it needs the repository's code, as LFM3 was read. A reading that credits Transformers gives 5
The tie from SenseNova to SenseTime rests on SenseTime's site, which presents SenseNova as its model series. Neither the card nor the Hub organisation names SenseTime
Capability is pending because no independent results were looked up on the day
unchecked on 10 November: the repository's model code, the two pull requests, LightLLM, the training guides, GitHub issues, README_CN.md, and SenseNova's hosted platform, whose robots.txt disallows reading

Probe metrics

Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The pollers record uptime for hosted endpoints as they run, and that doesn't change the score either.

Pricing & changes

Free Free Free to download and use under Apache 2.0. Running it yourself costs the hardware: the files are 38.1 GB because most weights are stored in 32-bit floats, and the card's example loads them as BF16 (checked 2026-11-10).

No hosted version of these weights has a price on OpenRouter, so what a task costs is your own hardware and power. What tasks cost on hosted models.
