### Which Tar-7B does this page describe?

Tar-7B is a model record from **ByteDance Seed** in the Tar family. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B)

The recorded model identifier or checkpoint is `Tar-7B`. Use that exact identifier when checking documentation or a provider listing. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B)

### How can you access Tar-7B?

The catalog documents **Open weights** access  for Tar-7B. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B)

As of the catalog check, this version was listed as available. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B)

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 license is recorded for Tar-7B?

The recorded license label is **apache-2.0**. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B)

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 Tar-7B?

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

**Research purpose**: Unified visual understanding and generation using text-aligned representations. [Source](https://huggingface.co/ByteDance-Seed/Tar-7B/resolve/b137de641a0a1d3262fdc7d9e7f8ee5c48ac1467/README.md)

**Declared language backbone**: Qwen/Qwen2.5-7B-Instruct [Source](https://huggingface.co/ByteDance-Seed/Tar-7B/resolve/b137de641a0a1d3262fdc7d9e7f8ee5c48ac1467/README.md)

### What is documented about the Tar-7B checkpoint?

This evidence refers to `ByteDance-Seed/Tar-7B` at recorded revision `b137de641a0a1d3262fdc7d9e7f8ee5c48ac1467`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/ByteDance-Seed/Tar-7B)

Safetensors metadata records **8,690,574,534 stored parameters**. This is a stored-weight count, not necessarily the number activated per token, a download size or a GPU-memory requirement. [Repository metadata](https://huggingface.co/api/models/ByteDance-Seed/Tar-7B)

Recorded architecture class: `LlavaQwenForCausalLM`. [Repository metadata](https://huggingface.co/api/models/ByteDance-Seed/Tar-7B)

Repository task tag: `any-to-any`. A task tag identifies a distribution category; it does not measure performance on that task. [Repository metadata](https://huggingface.co/api/models/ByteDance-Seed/Tar-7B)

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/ByteDance-Seed/Tar-7B)

#### What the configuration file says

The pinned `config.json` contains these values. [Pinned configuration](https://huggingface.co/ByteDance-Seed/Tar-7B/resolve/b137de641a0a1d3262fdc7d9e7f8ee5c48ac1467/config.json)

`max_position_embeddings`: 32,768

`sliding_window`: 131,072

`torch_dtype`: bfloat16

`num_attention_heads`: 28

`num_key_value_heads`: 4

`num_hidden_layers`: 28

`hidden_size`: 3,584

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 weight listing; availability refers to this distribution, not a guaranteed hosted API. Base, SFT and research variants are identified by their exact published names.

**Evidence still missing here:** context or input capacity, 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.
