AI21-Jamba-Mini-1.7 is a model record from **AI21 Labs** in the Jamba family. [Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7) 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 AI21-Jamba-Mini-1.7? The catalog documents **API and Open weights** access for AI21-Jamba-Mini-1.7. [Source](https://docs.ai21.com/docs/jamba-foundation-models) As of the catalog check, this version was marked deprecated. [Source](https://docs.ai21.com/docs/jamba-foundation-models) Check the linked lifecycle information before starting a new integration. For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription. 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. This record documents API access separately. ### What are AI21-Jamba-Mini-1.7's context and output limits? The publisher reports the context window as **256K tokens**. [Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/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 dates are documented for AI21-Jamba-Mini-1.7? **Knowledge cutoff: August 22, 2024.** [Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/README.md) This labels the documented knowledge boundary; it is not a promise that every earlier fact is known or correct. The source labels this “- Knowledge cutoff date: August 22nd, 2024.” 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 license is recorded for AI21-Jamba-Mini-1.7? The recorded license label is **jamba-open-model-license**. [Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7) 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 AI21-Jamba-Mini-1.7? These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results. **Hybrid architecture**: Joint Attention and Mamba hybrid with a documented 256K context window; 1.7 emphasizes grounding and instruction following.

[Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/README.md) **Deployment requirements**: The default BF16/vLLM setup supports 200K-token prompts on 2×80GB A100 GPUs; the card describes additional GPUs for the full 256K context. [Source](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/README.md) ### What is documented about the AI21-Jamba-Mini-1.7 checkpoint? This evidence refers to `ai21labs/AI21-Jamba-Mini-1.7` at recorded revision `e8986f3aa2e7ce119329cde6120238f8802f92cb`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/ai21labs/AI21-Jamba-Mini-1.7) Safetensors metadata records **51,570,323,328 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/ai21labs/AI21-Jamba-Mini-1.7) Recorded architecture class: `JambaForCausalLM`. [Repository metadata](https://huggingface.co/api/models/ai21labs/AI21-Jamba-Mini-1.7) Repository access gate: `auto`. This records the repository's gate setting when checked; licensing and use terms still apply. [Repository metadata](https://huggingface.co/api/models/ai21labs/AI21-Jamba-Mini-1.7) Read the retrieved model card for setup and qualifications. [Model card](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/README.md) **Catalog qualifications:** Official publisher model repository; listed status confirms a catalog entry, not a verified hosted API service. The model card could not be retrieved anonymously; only public publisher metadata was used. Remaining fields need verification. API lifecycle is separate from downloadable weights. The shared vendor overview gives inconsistent knowledge/training recency statements, so no family-wide cutoff is copied into this version. [Source 1](https://huggingface.co/api/models/ai21labs/AI21-Jamba-Mini-1.7) · [Source 2](https://huggingface.co/ai21labs/AI21-Jamba-Mini-1.7/resolve/e8986f3aa2e7ce119329cde6120238f8802f92cb/README.md) **Evidence still missing here:** complete input/output pricing 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. Keep the exact version in view ## Other Jamba models from AI21 Labs. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [AI21-Jamba-Large-1.7](https://headlessthrones.com/models/ai21-labs-ai21-jamba-large-1-7) API · Open weights · 256,000 context tokens ### [AI21-Jamba2-3B](https://headlessthrones.com/models/ai21-labs-ai21-jamba2-3b) Open weights · 256,000 context tokens ### [AI21-Jamba2-Mini](https://headlessthrones.com/models/ai21-labs-ai21-jamba2-mini) API · Open weights · 256,000 context tokens ### [AI21-Jamba-Large-1.5](https://headlessthrones.com/models/ai21-labs-ai21-jamba-large-1-5) API · Open weights ### [AI21-Jamba-Large-1.6](https://headlessthrones.com/models/ai21-labs-ai21-jamba-large-1-6) API · Open weights ### [AI21-Jamba-Mini-1.5](https://headlessthrones.com/models/ai21-labs-ai21-jamba-mini-1-5) API · Open weights
