Step1: Chat Template for Unified Instruct Model and Thinking Model

Inspired by Deepseek V3.1, we have unified the chat templates of Qwen3-2507-Instruct and Qwen3-2507-Thinking.
Now, you can switch between No-Thinking and Thinking modes by modifying set thinking to false or true!

Step2: Hybrid Instruct Model and Thinking Model

We have improved the mixing ratio of Qwen3-30B-A3B-Mixture-2507, enabling the model to switch smoothly between thinking and non-thinking modes!

models:
  - model: Qwen/Qwen3-30B-A3B-Thinking-2507
    parameters:
      weight: 1.4
  - model: Qwen/Qwen3-30B-A3B-Instruct-2507
    parameters:
      weight: 0.6
merge_method: nuslerp
tokenizer_source: base
dtype: bfloat16
name: Qwen3-30B-A3B-Mixture-V2

Step3: Incorporating Code Model and Adjusting Context Length

After numerous attempts, we unexpectedly discovered that in the scenario of merging code models, the nearswap merging method performs exceptionally well—it not only outperforms all previous baseline methods but also further improves code performance while preserving the characteristics of the base model.
By referring to the config_1m.json of Qwen3-30B-A3B-Instruct-2507, we modified the config.json of the merged model and extended the maximum context length to 1M.

models:
  - model: Qwen/Qwen3-Coder-30B-A3B-Instruct
merge_method: nearswap
base_model: Qwen3-30B-A3B-Mixture-V2
parameters:
  t:
    - value: 0.001
tokenizer_source: base
dtype: bfloat16

Model merging may inevitably result in performance degradation: even in non-thinking mode, the model might produce lengthy reasoning chains when faced with challenging problems; in thinking mode, it may output reasoning chains without final summaries.

We are committed to optimizing this in the next version and encourage developers to fine-tune this model or use it as a base for distilling larger models to further enhance performance.
