Typhoon Ocr1.5 2B — Hardware Requirements & GPU Compatibility
VisionTyphoon OCR 1.5 2B is OpenTyphoon's 2.1-billion-parameter vision-language OCR model for English and Thai documents, built on Qwen3-VL-2B-Instruct. Compared with the first Typhoon OCR, the card says it is faster because it no longer needs embedded PDF metadata for layout, uses a single prompt instead of two, and handles handwriting, forms and image-rich pages better. It is meant to be used with its specific prompt only. At this size, it runs on lightweight hardware, including a modest consumer GPU. The context window is 262,144 tokens. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use, with the card asking users to accept the OpenTyphoon terms. Published in November 2025, it replaces the larger Typhoon OCR 3B built on Qwen2.5-VL. The card recommends the Ollama build for local use, since GGUF conversions may suffer accuracy issues.

Frequently Asked Questions
- How much VRAM does Typhoon Ocr1.5 2B need?
Typhoon Ocr1.5 2B requires 1.8 GB of VRAM at Q4_K_M, or 4.8 GB at BF16. Full 262K context adds up to 29.8 GB (31.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 2.1B × 4.8 bits ÷ 8 = 1.3 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 30.3 GB (at full 262K context)
