Exact catalog ID: `arcee-ai-afm-4-5b-ov`. 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 AFM-4.5B-ov 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/arcee-ai-afm-4-5b-ov#model-answer-identity) · [Access](https://headlessthrones.com/models/arcee-ai-afm-4-5b-ov#model-answer-access) · [Inputs & outputs](https://headlessthrones.com/models/arcee-ai-afm-4-5b-ov#model-answer-modalities) · [License](https://headlessthrones.com/models/arcee-ai-afm-4-5b-ov#model-answer-license) · [Model details](https://headlessthrones.com/models/arcee-ai-afm-4-5b-ov#model-answer-research) · [Weight details](https://headlessthrones.com/models/arcee-ai-afm-4-5b-ov#model-answer-repository) ### Which AFM-4.5B-ov does this page describe? AFM-4.5B-ov is a model record from **Arcee AI** in the AFM family. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) 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 AFM-4.5B-ov? The catalog documents **Open weights** access for AFM-4.5B-ov. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) As of the catalog check, this version was listed without confirmed general availability. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) 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 can AFM-4.5B-ov receive and generate? Documented inputs: **text**. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) Documented outputs: **text**. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) 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 AFM-4.5B-ov? The recorded license label is **apache-2.0**. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov) 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 AFM-4.5B-ov? These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results. **OpenVINO checkpoint format**: Provides 16-bit, 8-bit and 4-bit OpenVINO versions of the AFM 4.5B instruction model.

[Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov/resolve/e8af8eb54184d1ac77090bd829d23d2f8a492bd7/README.md) **Base model lineage**: The underlying AFM 4.5B model received 6.5 trillion pretraining tokens, 1.5 trillion midtraining tokens, instruction fine-tuning and reinforcement learning; this repository supplies converted weights. [Source](https://huggingface.co/arcee-ai/AFM-4.5B-ov/resolve/e8af8eb54184d1ac77090bd829d23d2f8a492bd7/README.md) ### What is documented about the AFM-4.5B-ov checkpoint? This evidence refers to `arcee-ai/AFM-4.5B-ov` at recorded revision `e8af8eb54184d1ac77090bd829d23d2f8a492bd7`, checked October 23, 2026. [Repository metadata](https://huggingface.co/api/models/arcee-ai/AFM-4.5B-ov) 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/arcee-ai/AFM-4.5B-ov) Listed library: `transformers`. Check that library's version and model support before loading the weights. [Repository metadata](https://huggingface.co/api/models/arcee-ai/AFM-4.5B-ov) Repository language labels: en, es, fr, de, it, pt, ru, ar, hi, ko, and zh. These labels are not independent evaluations of language quality. [Repository metadata](https://huggingface.co/api/models/arcee-ai/AFM-4.5B-ov) Repository access gate: `false`. This records the repository's gate setting when checked; licensing and use terms still apply.

[Source 1](https://huggingface.co/api/models/arcee-ai/AFM-4.5B-ov) · [Source 2](https://huggingface.co/arcee-ai/AFM-4.5B-ov/resolve/e8af8eb54184d1ac77090bd829d23d2f8a492bd7/README.md) **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 AFM models from Arcee AI. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [AFM-4.5B](https://headlessthrones.com/models/arcee-ai-afm-4-5b) Open weights ### [AFM-4.5B-Base](https://headlessthrones.com/models/arcee-ai-afm-4-5b-base) Open weights ### [AFM-4.5B-Preview](https://headlessthrones.com/models/arcee-ai-afm-4-5b-preview) Open weights
