Key Features
Massive Context Windows: Both models support up to 1M tokens, enabling analysis of entire codebases, research papers, and extensive conversation histories without truncation.
Efficient Architecture: Despite offering frontier-level performance, both models maintain exceptional efficiency through optimized mixture-of-experts design and active parameter count of just 3.3B.
Flexible Reasoning (Plus Only): aquif-3.5-Plus provides interchangeable thinking modes—enable reasoning for complex problems, disable for faster inference on straightforward tasks.
Multilingual Support: Native support across English, German, Italian, Portuguese, French, Hindi, Spanish, Thai, Chinese, and Japanese.
Usage Recommendations
aquif-3.5-Plus:
- Complex reasoning requiring flexibility between speed and depth
- Scientific analysis and mathematical problem-solving with thinking enabled
- Rapid-response applications with thinking disabled
- Code generation and review

Setting Thinking Mode (aquif-3.5-Plus)
Toggle between thinking and non-thinking modes by modifying the chat template:
set thinking = true # Enable reasoning mode
set thinking = false # Disable thinking mode (faster inference)
Simply set the variable in your chat template before inference to switch modes. No model reloading required.
Technical Specifications
Both models support:
- BF16 and FP16 precision
- Mixture of Experts architecture optimizations
- Efficient attention mechanisms with optimized KV caching
