Apache 2.0 + triple weight licensing（foundation/dialogue/thinking）directly released on Hugging Face. Humaneval 41.46% isn’t top-tier, but it’s friendly for engineering deployment—companies can consider self-hosting.

JetBrains open-source Mellum-2, a 12B parameter code-mixed expert model. To control inference costs, only about 2.5 billion parameters are activated per token, with weights already released on Hugging Face, Apache 2.0. A new multi-token prediction (MTP) module has been added, where the MTP head acts as a draft model to accelerate sampling during inference. Provides three versions: basic, dialogue, and thinking; the thinking version can display explicit reasoning chains before output. Benchmarks: Humaneval 41.46%, MMLU 70.87%.
