because each is its own product: [Hermes Agent](https://www.anchorterminal.com/tools/hermes-agent.md) (Personal assistants).\n\nTrained by Nous Research (NousResearch), in the Arete family. Every model from this lab and its older versions: https://www.anchorterminal.com/open-weights/#nous-research.\n\n## Assessment\n\nQwen3.8-27B with its answers on politically sensitive topics retrained, four days old when read. The training data is published, which is rare. Nous Research ships BF16 only, so a small machine runs it from bartowski's GGUF, and the card documents none of the tool or thinking controls it inherits.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Nous Research (https://nousresearch.com) |\n| Kind | Open-weight model |\n| Category | Open-weight models (https://www.anchorterminal.com/categories/open-weights) |\n| Auth | None · The weights download from Hugging Face with no account, token or terms to accept. The repository is not gated (checked 2026-11-10). |\n| Pricing | Free (Free) · Free to download and use, commercial use included, under Apache 2.0, in the card's metadata and as a LICENSE file in the repository. Running it yourself costs the hardware, 54.7 GB for the BF16 files, or 18.1 GB for bartowski's Q4_K_M GGUF with its projector (checked 2026-11-10). |\n| x402 | No · Weights you download and run yourself, so there is nothing to pay per call and no payment protocol (checked 2026-11-10). |\n| Licence | Apache-2.0 |\n| Packages | huggingface: `NousResearch/Arete-27B` |\n| Source | https://huggingface.co/NousResearch/Arete-27B |\n| Docs | https://huggingface.co/NousResearch/Arete-27B |\n| llms.txt | not found |\n| Last release | 2026-11-06 |\n| Surface graded | The open weights at huggingface.co/NousResearch/Arete-27B, read from the model card, the files and their metadata, the chat template, Nous Research's blog post and the runtimes' own code at their latest releases on 10 November 2026. Nothing was downloaded or run |\n| Model | 27,356,728,560 parameters in BF16 per the safetensors metadata, Qwen3.8-27B's architecture (Qwen3_5ForConditionalGeneration) with 64 layers and its vision encoder. The card says all language-model weights were trained, the vision encoder was frozen and the multi-token-prediction head was off during training. Text, images and video in, as the base |\n| Files | 18 safetensors shards in BF16 (54.7 GB), a chat_template.jinja, the tokenizer and processor configs, and an Apache 2.0 LICENSE. No pickle or Python files. Hugging Face lists a SHA-256 for every large file |\n| Licence | Apache 2.0, in the card's metadata and as the LICENSE file. The base, Qwen3.8-27B, is Apache 2.0 too. Nothing is added on the card |\n| Runtimes | The architecture is the base's, which released vLLM (0.33.0), SGLang (0.5.23) and Transformers (5.22.2) run from the safetensors files. llama.cpp b12242 converts and runs it, and Nous Research publishes no GGUF, so that route goes through bartowski's conversion. Ollama's library has no entry for it |\n| Context | 262,144 tokens native (max_position_embeddings in the text config). The card says training ran at 64K context |\n| Tools and reasoning | The chat template is the base's with small changes. It declares tools in a tools block, renders several function calls in one turn inside tool_call, and switches thinking with enable_thinking and reasoning_effort. The card documents none of this. Its evaluation ran with thinking off |\n| Hardware | 54.7 GB in BF16, about 66 GB with the fifth added, which fits a 128 GB unified machine. bartowski's Q4_K_M GGUF is 17.2 GB and its Q8_0 28.7 GB, each with a 0.93 GB projector |\n| Training data | Published. 28,886 training examples (the blog's count) from twenty thousand prompts across seven value categories, with teacher answers from Inkling beside the base model's own, about 52.8 million tokens over two epochs. The held-out evaluation, 803 prompts with a source article for each, is published too |\n| What changed | Answers on freedom of expression, state ideology, state versus free market, education, data privacy and surveillance, democracy and environmental policy. The card says it doesn't claim to have remedied every such behaviour |\n| Capabilities | model.open-weights |\n| Tags | open-weights, model, fine-tune, qwen, multimodal, vision, reasoning, tool-calling, apache-2.0, safetensors, self-hosted |\n| JSON | https://www.anchorterminal.com/api/v1/tools/arete-27b.json |\n\n## Score breakdown (methodology v0.7, October 2026 research run)\n\nAssessed 2026-11-10 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). Confidence: low. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Capability | 35% | pending | pending | n/a |\n| Reach | 25% | 38.5 | 50 | 19.2 |\n| Risk | 20% | 30.8 | 55 | 16.9 |\n| Agent interface | 10% | 15.4 | 60 | 9.2 |\n| Documentation and upkeep | 10% | 15.4 | 63 | 9.7 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **55.1 → C** |\n\n### Why each score\n\n- Capability: Pending for this listing. Nobody independent has published results for it in at least two areas yet, so its weight is shared across the other four and the total is capped at 61 until they do or our own runs start.\n- Reach 50 (checked 2026-11-10): Memory 10, the only build from Nous Research is the 54.7 GB BF16 release, which needs about 66 GB and fits the reference machine. Runtimes 15, vLLM, SGLang and Transformers run the base's architecture from those files, and llama.cpp isn't credited because Nous Research publishes no GGUF. Builds 0, no quantised build of its own. Terms 15, Apache 2.0. Download 10, not gated. Hosted 0, no provider. 10 + 15 + 0 + 15 + 10 + 0 = 50.\n- Risk 55 (checked 2026-11-10): File safety 25, safetensors only and no remote code. Provenance 15, Nous Research's own organisation, linked from its blog, with a hash on every file. Safety evaluation 0 and agent guidance 0, nothing published on either. Licence risk 15, plain Apache 2.0. Security programme 0, no way to report a flaw found. 25 + 15 + 0 + 0 + 15 + 0 = 55.\n- Agent interface 60 (checked 2026-11-10): Chat template 20, a Jinja file in the repository. Tool-calling format 10, only the template says it. Trained tool calling 20, several calls a turn and agentic work as an intended use. Structured output 0 and reasoning control 0, neither is documented on the card. Context 10, 262,144 tokens native. 20 + 10 + 20 + 0 + 0 + 10 = 60.\n- Documentation and upkeep 63 (checked 2026-11-10): Model card 8, no limitations, context length, languages or cut-off. Training data 20, the training pairs and the evaluation set are published with their counts. Last change 20, a commit on 6 November 2026. Responsiveness 0, none of 13 discussions has a reply from Nous Research. Version policy 5, a first release. File health 10, the files agree. 8 + 20 + 20 + 0 + 5 + 10 = 63.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (14 items). What it covers is at https://www.anchorterminal.com/fixes/arete-27b.md (JSON https://www.anchorterminal.com/fixes/arete-27b.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"arete-27b\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- Runtimes is 15 by the ruling that a derivative gets runtime credit only for its own builds. Read by architecture alone, as three earlier fine-tunes of Qwen3.8-27B were (each has its own GGUF), llama.cpp adds 5 and Reach is 55\n- Memory reads the BF16 build, the only one from the publisher. With bartowski's Q4_K_M counted it would be 25 and Reach 65, which the spec on third-party builds leaves open\n- File health is 10 with 13 discussions unanswered by Nous Research. If one of them reports a broken file, the line is 5\n- The vLLM command uses the base's parsers and flags and isn't on the card. The template differs from the base's by 52 characters and the difference wasn't read line by line\n- Whether a fine-tune made to change political answers should be noted under Risk wasn't decided. The October question on models trained on other labs' outputs is still open, and Inkling was the teacher here\n- Confidence is low by the checklist's rule, since no independent results exist for a model four days old\n- unchecked: the domain's registration date, security.txt on nousresearch.com on the day, and the contents of the training dataset beyond its name and the counts given\n\n### Sources\n\n- model card: \u003chttps://huggingface.co/NousResearch/Arete-27B\u003e (seen 2026-11-10)\n- gating, dates, parameter count, downloads, likes, file list and hashes: \u003chttps://huggingface.co/api/models/NousResearch/Arete-27B?blobs=true\u003e (seen 2026-11-10)\n- inference providers, none: \u003chttps://huggingface.co/api/models/NousResearch/Arete-27B?expand[]=inferenceProviderMapping\u003e (seen 2026-11-10)\n- commit history: \u003chttps://huggingface.co/api/models/NousResearch/Arete-27B/commits/main\u003e (seen 2026-11-10)\n- licence file: \u003chttps://huggingface.co/NousResearch/Arete-27B/raw/main/LICENSE\u003e (seen 2026-11-10)\n- architecture and context length: \u003chttps://huggingface.co/NousResearch/Arete-27B/raw/main/config.json\u003e (seen 2026-11-10)\n- chat template: \u003chttps://huggingface.co/NousResearch/Arete-27B/raw/main/chat_template.jinja\u003e (seen 2026-11-10)\n- the base's chat template, for comparison: \u003chttps://huggingface.co/Qwen/Qwen3.8-27B/raw/main/chat_template.jinja\u003e (seen 2026-11-10)\n- tokenizer config, no second template: \u003chttps://huggingface.co/NousResearch/Arete-27B/raw/main/tokenizer_config.json\u003e (seen 2026-11-10)\n- discussions, replies counted by script from authors, dates and member flags: \u003chttps://huggingface.co/api/models/NousResearch/Arete-27B/discussions\u003e (seen 2026-11-10)\n- Nous Research's repositories for Arete: \u003chttps://huggingface.co/api/models?author=NousResearch\u0026search=Arete\u003e (seen 2026-11-10)\n- Nous Research's blog post, links to the weights and both datasets: \u003chttps://nousresearch.com/arete\u003e (seen 2026-11-10)\n- the training dataset: \u003chttps://huggingface.co/api/datasets?author=NousResearch\u0026search=Arete\u003e (seen 2026-11-10)\n- bartowski's GGUF files and sizes: \u003chttps://huggingface.co/api/models/bartowski/NousResearch_Arete-27B-GGUF?blobs=true\u003e (seen 2026-11-10)\n- vLLM v0.33.0 registry, Qwen3_5ForConditionalGeneration: \u003chttps://raw.githubusercontent.com/vllm-project/vllm/v0.33.0/vllm/model_executor/models/registry.py\u003e (seen 2026-11-10)\n- SGLang v0.5.23 qwen3_5.py: \u003chttps://raw.githubusercontent.com/sgl-project/sglang/v0.5.23/python/sglang/srt/models/qwen3_5.py\u003e (seen 2026-11-10)\n- Transformers v5.22.2 qwen3_5 model: \u003chttps://raw.githubusercontent.com/huggingface/transformers/v5.22.2/src/transformers/models/qwen3_5/configuration_qwen3_5.py\u003e (seen 2026-11-10)\n- llama.cpp b12242, the Qwen conversion code (shallow clone): \u003chttps://raw.githubusercontent.com/ggml-org/llama.cpp/b12242/conversion/qwen.py\u003e (seen 2026-11-10)\n\n## Score history\n\nEvery move of a score since the listing was graded, newest first, with its cause.

X: https://x.com/Teknium. GitHub: https://github.com/teknium1\n- Dillon Rolnick, CEO, Nous Research\n- Note: Copied from the Hermes Agent listing. Nous Research has no team page. Its October 2026 fundraise note is signed by Dillon Rolnick, CEO, Nous Research. Teknium's own site, teknium.io, describes Teknium as cofounder of Nous Research and lead engineer of Hermes Agent, formerly head of post-training for the Hermes models, and links Teknium's X, GitHub and Hugging Face accounts. No Nous page we read names its other founders.\n- Nous Research: LinkedIn https://www.linkedin.com/company/nousresearch X https://x.com/NousResearch\n\n### Ownership and investors\n\n- Valuation: $1.5B as announced (the source doesn't say pre- or post-money), Series B, October 2026 (source https://www.sidley.com/en/newslanding/newsannouncements/2026/10/sidley-represents-nous-research-in-us-90-million-series-b-financing)\n- Backed by: Robot Ventures, NVIDIA, Microsoft, Samsung, Union Square Ventures, Y Combinator, Menlo Ventures, Paradigm, Distributed Global, North Island Ventures, Delphi Digital\n\n### Getting support\n\n- Discord: https://discord.gg/nousresearch\n- Help: https://nousresearch.com/contact\n- Help: https://huggingface.co/NousResearch/Arete-27B/discussions\n- Community (GitHub): https://github.com/NousResearch/hermes-agent\n- Sources: https://teknium.io, https://github.com/NousResearch/hermes-agent, https://x.com/Teknium, https://hermes-agent.nousresearch.com/, https://www.linkedin.com/company/nousresearch, https://hermes-agent.nousresearch.com, https://x.com/NousResearch, https://nousresearch.com/contact\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\nNo hosted version of these weights has a price on OpenRouter, so what a task costs is your own hardware and power.\n\n## Strengths\n\n- The training pairs and the evaluation set are both published\n- Apache 2.0, ungated, safetensors only, no remote code\n- The base's architecture, so vLLM, SGLang and Transformers run it from their releases\n- Fits a 128 GB machine in BF16, and 24 GB from bartowski's 4-bit GGUF\n- Nous Research reports no meaningful loss against the base on its agent benchmarks\n\n## Weaknesses\n\n- No quantised build from Nous Research, so the GGUF route depends on a third party\n- The card doesn't document tool calling, structured output or how to switch thinking\n- No limitations section, safety results or security contact\n- None of the 13 discussions has a reply from Nous Research\n- The results are Nous Research's own evaluation and nobody else has rerun it yet\n\n\n\n## Before you call it (notes for agents)\n\n1. Start it with `llama-server -hf bartowski/NousResearch_Arete-27B-GGUF:Q4_K_M --jinja`, a third party's conversion, or serve the BF16 files with vLLM\n2. Use the base's parsers in vLLM, `--reasoning-parser qwen3 --tool-call-parser qwen3_coder`, and check tool calls first, since the template differs slightly from Qwen3.8-27B's\n3. Thinking switches with `enable_thinking` in the template. The card's own evaluation ran with it off\n4. Expect answers on politically sensitive topics to differ from Qwen3.8-27B's. That is what the fine-tune is for\n5. Validate JSON output yourself, since structured output isn't documented\n\n## Get started\n\nInstall:\n\n```bash\nvllm serve NousResearch/Arete-27B --max-model-len 262144 --reasoning-parser qwen3 \\\n --enable-auto-tool-choice --tool-call-parser qwen3_coder\n# or, with llama.cpp and bartowski's GGUF, a third party's conversion:\nllama-server -hf bartowski/NousResearch_Arete-27B-GGUF:Q4_K_M --jinja\n```\n\nFirst request:\n\n```bash\ncurl http://localhost:8000/v1/chat/completions \\\n -H \"Content-Type: application/json\" \\\n -d '{\"model\": \"NousResearch/Arete-27B\", \"messages\": [{\"role\": \"user\", \"content\": \"Hello!\"}]}'\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on nousresearch.com or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"arete-27b\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
