Llama 2 13b chat is a model record from **Meta** in the Llama 2 family. [Source](https://huggingface.co/meta-llama/Llama-2-13b-chat) The recorded model identifier or checkpoint is `meta-llama/Llama-2-13b-chat`. Use that exact identifier when checking documentation or a provider listing. [Source](https://huggingface.co/meta-llama/Llama-2-13b-chat) ### How can you access Llama 2 13b chat? The catalog documents **Open weights** access for Llama 2 13b chat. [Source](https://huggingface.co/meta-llama/Llama-2-13b-chat) As of the catalog check, this version was listed as available. [Source](https://huggingface.co/meta-llama/Llama-2-13b-chat) 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 Llama 2 13b chat's context and output limits? The documented **context window is 4,000 tokens**. [Source](https://github.com/meta-llama/llama-models/blob/main/models/llama2/MODEL_CARD.md) 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 dates are documented for Llama 2 13b chat? **Training-data cutoff: September 2022.** [Source](https://github.com/meta-llama/llama-models/blob/main/models/llama2/MODEL_CARD.md) This describes the reported data boundary, not the day training finished. The source labels this “Pretraining data cutoff; tuning data extends through July 2023.” Retrieval or web tools can supply newer information at run time. That does not change the model's recorded training or knowledge dates, and this record does not establish that a particular endpoint includes those tools. ### What can Llama 2 13b chat receive and generate? Documented inputs: **text**. [Source](https://github.com/meta-llama/llama-models/blob/main/models/llama2/MODEL_CARD.md) Documented outputs: **text**. [Source](https://github.com/meta-llama/llama-models/blob/main/models/llama2/MODEL_CARD.md) 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 Llama 2 13b chat? The recorded license label is **Llama 2 Community License**. [Source](https://github.com/meta-llama/llama-models/blob/main/models/llama2/MODEL_CARD.md) 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 is documented about the Llama 2 13b chat checkpoint? This evidence refers to `meta-llama/Llama-2-13b-chat` at recorded revision `9d1dbc9c82b4eed25bd5b0c9805898c66dcd1db9`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/meta-llama/Llama-2-13b-chat) 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/meta-llama/Llama-2-13b-chat) Repository language labels: en. These labels are not independent evaluations of language quality. [Repository metadata](https://huggingface.co/api/models/meta-llama/Llama-2-13b-chat) Repository access gate: `manual`. This records the repository's gate setting when checked; licensing and use terms still apply.

[Model card](https://huggingface.co/meta-llama/Llama-2-13b-chat/resolve/9d1dbc9c82b4eed25bd5b0c9805898c66dcd1db9/README.md) **Catalog qualifications:** Vendor family training interval January–July 2023; not assumed to be a checkpoint-specific training-completion date. [Source 1](https://huggingface.co/api/models/meta-llama/Llama-2-13b-chat) · [Source 2](https://huggingface.co/meta-llama/Llama-2-13b-chat/resolve/9d1dbc9c82b4eed25bd5b0c9805898c66dcd1db9/README.md) **Evidence still missing here:** 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. Keep the exact version in view ## Other Llama 2 models from Meta. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [Llama 2 13b](https://headlessthrones.com/models/llama-2-13b) Open weights · 4,000 context tokens ### [Llama 2 70b](https://headlessthrones.com/models/llama-2-70b) Open weights · 4,000 context tokens ### [Llama 2 70b chat](https://headlessthrones.com/models/llama-2-70b-chat) Open weights · 4,000 context tokens ### [Llama 2 7b](https://headlessthrones.com/models/llama-2-7b) Open weights · 4,000 context tokens ### [Llama 2 7b chat](https://headlessthrones.com/models/llama-2-7b-chat) Open weights · 4,000 context tokens
