HunyuanOCR How much memory it needs, what its licence allows, and whether it fits an office box.
Short answer. HunyuanOCR needs about 2.1 GB of memory at 4-bit, 2.7 GB at 8-bit and 3.7 GB at full 16-bit precision, including runtime overhead. It has about 1.1 billion parameters and a 131,072-token context window. Licence in short: custom licence: check before commercial use. By memory alone, on ANVE’s launch configurations: ANVE One fits at BF16, ANVE Office fits at BF16, ANVE Office Pro (GPU) fits at BF16. These are estimates from its published size, not benchmarks.
01
What it is
HunyuanOCR is a document-reading model that turns scanned pages and images into text, published by Tencent on Hugging Face on 18 November 2025. It has about 1.1 billion parameters and a configured context window of 131,072 tokens.
Its card lists the licence as a custom licence (tencent-hunyuan-community). In short, the licence sets its own terms; read it before any commercial use.
Hugging Face counted about 929,080 downloads of it in the 30 days before we checked (7 Oct 2026), and 827 people have liked it there.
The card lists 3 languages: multilingual, en, zh (ISO codes as given on the card).
02
How much memory it needs
The arithmetic: parameters × bits per weight ÷ 8 gives the weights, plus about 1.5 GB for the runtime. These are planning estimates, not measurements.
Inputs are short, so working memory is small next to the weights.

Will it fit on ANVE?
Arithmetic against the launch specification, not a test: about three quarters of ANVE One’s 64 GB of unified memory for the model (as AMD’s Variable Graphics Memory allows), and the 24 GB on the graphics card in ANVE Office and ANVE Office Pro, which keep the rest of the stack in 64 GB and 128 GB of system memory. ANVE’s tested default is Qwen 3.8 27B; this model is not yet validated on ANVE.

What an office would use it for
For an office, this is how scanned invoices, letters and forms become searchable text. Check its output on your own documents, especially tables, stamps and handwriting.

Questions people ask
How much memory does HunyuanOCR need?
About 2.1 GB at 4-bit, 2.7 GB at 8-bit and 3.7 GB at full 16-bit precision, including about 1.5 GB of runtime overhead. These are estimates from its parameter count.
Can HunyuanOCR run on a 24 GB graphics card?
Yes, at BF16 by this estimate, with room left for context.
Is HunyuanOCR free for commercial use?
Its card lists a custom licence (tencent-hunyuan-community), which sets its own terms; read it before any commercial use. Read the licence itself before relying on this summary; it is not legal advice.
What is HunyuanOCR’s context window?
Its configuration sets 131,072 tokens. Longer contexts need more memory for the KV cache, so the practical limit on a given machine can be lower.
