### Which Nous-Capybara-34B does this page describe?

Nous-Capybara-34B is a model record from **Nous Research** in the Nous family. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B)

A separate version identifier is not documented in this record; the model name alone does not establish which snapshot a service runs.

### How can you access Nous-Capybara-34B?

The catalog documents **Open weights** access  for Nous-Capybara-34B. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B)

As of the catalog check, this version was listed without confirmed general availability. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B)

Open weights means the model weights are distributed for use under their stated terms. It does not establish a hosted API, an open-source license, or a hardware requirement.

### What are Nous-Capybara-34B's context and output limits?

The publisher reports the context window as **200K tokens**. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/README.md) We retain the publisher's notation and qualifiers; no exact token count or hosted serving allowance is inferred from it.

A separate maximum-output value is not established in this record. The context or input figure should not be used as an output allowance.

Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity.

### What can Nous-Capybara-34B receive and generate?

Documented inputs: **text**. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B)

Documented outputs: **text**. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B)

Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation.

### What license is recorded for Nous-Capybara-34B?

The recorded license label is **mit**. [Source](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Read the linked license and associated use terms for this exact version before redistribution, commercial deployment or fine-tuning. A label alone does not establish every permission, restriction or obligation, and it does not determine the terms of a separate hosted service.

### What distinguishes Nous-Capybara-34B?

These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results.

**Training data**: Fine-tuning uses approximately 20,000 curated examples, largely synthesized conversations. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/README.md)

**Base and context**: Fine-tuned from Yi 34B for three epochs on Capybara data, with the publisher’s 200K context window. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/README.md)

**Conversation emphasis**: More than 60% of the fine-tuning examples are multi-turn conversations. [Source](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/README.md)

### What is documented about the Nous-Capybara-34B checkpoint?

This evidence refers to `NousResearch/Nous-Capybara-34B` at recorded revision `6beb706364038ba43350d85734975377236e9546`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Recorded architecture class: `LlamaForCausalLM`. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Repository task tag: `text-generation`. A task tag identifies a distribution category; it does not measure performance on that task. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Listed library: `transformers`. Check that library's version and model support before loading the weights. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Repository language labels: eng. These labels are not independent evaluations of language quality. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

Repository access gate: `false`. This records the repository's gate setting when checked; licensing and use terms still apply. [Repository metadata](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B)

#### What the configuration file says

The pinned `config.json` contains these values. [Pinned configuration](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/config.json)

`max_position_embeddings`: 200,000

`torch_dtype`: bfloat16

`num_attention_heads`: 56

`num_key_value_heads`: 8

`num_hidden_layers`: 60

`hidden_size`: 7,168

Configuration values describe the checkpoint and its implementation. In particular, max\_position\_embeddings, sliding\_window and rope\_scaling do not independently establish an API context limit, tested usable length or hardware requirement. Runtime, quantization, cache, batch size and input length affect deployment behavior.

**Catalog qualifications:** Official publisher model repository; listed status confirms a catalog entry, not a verified hosted API service. [Source 1](https://huggingface.co/api/models/NousResearch/Nous-Capybara-34B) · [Source 2](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/README.md) · [Source 3](https://huggingface.co/NousResearch/Nous-Capybara-34B/resolve/6beb706364038ba43350d85734975377236e9546/config.json)

**Evidence still missing here:** knowledge and training-data cutoffs and tested hardware requirements. Missing documentation is not evidence that a feature is unavailable.

Headless Thrones has not independently benchmarked this model for this reference. Evaluate it on representative work before choosing it; these facts do not rank its accuracy, reliability, speed or suitability against another model.
