Small Qwen3.5 Models Dropped

🔑 Enhanced Key Takeaways

• •Qwen3.5 was released in February 2026 alongside Qwen3.5-Plus and Qwen3-Coder-Next, indicating a recent family of models before the small variants' discontinuation[1].
• •Larger Qwen3.5 variants like 122B-A10B and 35B-A3B have been actively tested by NVIDIA users with optimizations for single-GPU setups using vLLM[2].
• •The discontinuation aligns with industry commentary declaring the 'chatbot era dead' following Alibaba's Qwen3.5 drop on February 27, 2026[3].

🛠️ Technical Deep Dive

• •Qwen3.5-122B-A10B and 35B-A3B variants support FP8 quantization, achieving up to 40 tokens/s on single GPUs like Asus GX10 with 261k context window using vLLM 0.16.1rc1[2].
• •Deployment flags include --max-model-len auto, --gpu-memory-utilization 0.7, --enable-prefix-caching, --enable-auto-tool-choice, and --tool-call-parser qwen3_coder[2].
• •Models require tokenizer patches like mods/fix-qwen3-next-autoround for compatibility issues with TokenizersBackend[2].
