Exact catalog ID: `ibm-granite-4-1-30b-base`. Catalog source-check date: 2026-10-23. This brief contains the public catalog answers and any catalog guide, not private drafts, historical editorial revisions or independently measured rankings. The canonical HTML page may also display separately published editorial. Current catalog answers ## What to know about granite-4.1-30b-base AI-compiled from linked model documentation. This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026. [Exact model](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-identity) · [Access](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-access) · [Dates & knowledge](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-dates) · [Inputs & outputs](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-modalities) · [License](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-license) · [Weight details](https://headlessthrones.com/models/ibm-granite-4-1-30b-base#model-answer-repository) ### Which granite-4.1-30b-base does this page describe? granite-4.1-30b-base is a model record from **IBM** in the Granite family. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) 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 granite-4.1-30b-base? The catalog documents **Open weights** access for granite-4.1-30b-base. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) As of the catalog check, this version was listed without confirmed general availability. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) 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 dates are documented for granite-4.1-30b-base? **Release date: April 29, 2026.** [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) This is a release milestone, not a knowledge or training cutoff. Neither a knowledge cutoff nor a training-data cutoff is established here. A release date, repository upload or filename cannot supply those missing dates. ### What can granite-4.1-30b-base receive and generate? Documented inputs: **text**. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) Documented outputs: **text**. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) 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 granite-4.1-30b-base? The recorded license label is **apache-2.0**. [Source](https://huggingface.co/ibm-granite/granite-4.1-30b-base) 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 granite-4.1-30b-base checkpoint? This evidence refers to `ibm-granite/granite-4.1-30b-base` at recorded revision `9bb22a92d17f4a51788c4750d32764ed068d94f2`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/ibm-granite/granite-4.1-30b-base) Safetensors metadata records **28,865,728,512 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/ibm-granite/granite-4.1-30b-base) Recorded architecture class: `GraniteForCausalLM`. [Repository metadata](https://huggingface.co/api/models/ibm-granite/granite-4.1-30b-base) 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/ibm-granite/granite-4.1-30b-base) Listed library: `transformers`. Check that library's version and model support before loading the weights. [Repository metadata](https://huggingface.co/api/models/ibm-granite/granite-4.1-30b-base) 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/ibm-granite/granite-4.1-30b-base) #### What the configuration file says The pinned `config.json` contains these values. [Pinned configuration](https://huggingface.co/ibm-granite/granite-4.1-30b-base/resolve/9bb22a92d17f4a51788c4750d32764ed068d94f2/config.json) `max_position_embeddings`: 131,072 `torch_dtype`: bfloat16 `num_attention_heads`: 32 `num_key_value_heads`: 8 `num_hidden_layers`: 64 `hidden_size`: 4,096 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. Read the retrieved model card for setup and qualifications.

[Source 1](https://huggingface.co/api/models/ibm-granite/granite-4.1-30b-base) · [Source 2](https://huggingface.co/ibm-granite/granite-4.1-30b-base/resolve/9bb22a92d17f4a51788c4750d32764ed068d94f2/README.md) · [Source 3](https://huggingface.co/ibm-granite/granite-4.1-30b-base/resolve/9bb22a92d17f4a51788c4750d32764ed068d94f2/config.json) **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. Keep the exact version in view ## Other Granite models from IBM. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [granite-switch-4.1-30b](https://headlessthrones.com/models/ibm-granite-switch-4-1-30b) Open weights · 131,072 context tokens ### [granite-switch-4.1-8b](https://headlessthrones.com/models/ibm-granite-switch-4-1-8b) Open weights · 131,072 context tokens ### [granite-4.2-30b](https://headlessthrones.com/models/ibm-granite-4-2-30b) Open weights · 128,000 context tokens ### [granite-4.2-3b](https://headlessthrones.com/models/ibm-granite-4-2-3b) Open weights · 128,000 context tokens ### [granite-4.2-8b](https://headlessthrones.com/models/ibm-granite-4-2-8b) Open weights · 128,000 context tokens ### [granite-swash-2b](https://headlessthrones.com/models/ibm-granite-swash-2b) Open weights
