UnverifiedIQ3_S and IQ3_XXS both belong to 3-bit quantization, but IQ3_S retains more precision for key weights and generally performs more stably in multilingual tasks, especially non-English scenarios, at the cost of a slightly larger file size.75% similarUnverifiedAWQ (Activation-aware Weight Quantization) typically outperforms GPTQ at 4-bit quantization.67% similarUnverifiedQ4 is 4-bit quantization and IQ3 is 3-bit importance-aware quantization; Qwen3 27B is approximately 11–12 GB in size under IQ3 and approximately 15–16 GB under Q4.65% similarUnverifiedIn complex reasoning tasks, the number of reasoning tokens can far exceed the number of final output tokens, which is why the usage cost of the o1/o3 series is typically higher than that of GPT models at the same tier.64% similarUnverifiedTencent's own internal test data claims that Hunyuan V3 surpasses DeepSeek-V4-Pro in almost every domain, with only slight underperformance on MCP-related test items.64% similar
