• With OpenVINO.GenAI , we’ve been able to accelerate generation by ~1.3× using speculative decoding with a lightweight Qwen3-0.6B draft.
• By using speculative decoding and applying a simple pruning process to the draft, we pushed the speedup even further to ~1.4× We wrapped this up by showing how these improvements can be used to run a fast, local AI Agent with 🤗 smolagents Qwen3 Qwen3-8B is part of the latest Qwen family, trained with explicit agentic behaviors.
• It supports tool invocation, multi-step reasoning, and long-context handling capabilities, that make it well-suited for complex agent workflows.
• When integrated with frameworks like Hugging Face 🤗smolagents, QwenAgent, or AutoGen, it enables a wide range of agentic applications built around tool use and reasoning.
• Unlike single-turn chatbots, agentic applications rely on reasoning models that produce “thinking aloud” traces, intermediate steps that expand token usage, making inference speed critical to responsiveness.
