Qwen3.5 0.8B (Reasoning)
Analysis Summary
Qwen3.5 0.8B (Reasoning) is the thinking-mode variant of Alibaba's smallest Qwen3.5 model, with an intelligence index of 5 and a GPQA score of just 0.111. Coding capability is limited at 15, and the agentic index of 47.7 is modest. Long-context reasoning (lcr 0.053) and instruction following (ifbench 0.21) are very weak, and the tau2 score of 0.477 suggests unreliable task completion.
Despite the reasoning label, this model does not deliver meaningful reasoning at this scale. It is appropriate only for the simplest possible inference tasks: short-text classification, basic entity extraction, or as a lightweight component in a larger orchestrated system.
At $0.01/1M input, it is priced for volume. Businesses should treat it as a utility component rather than a capable reasoning engine, and should validate outputs carefully before any production use.
