Pinkstack releases Fijik 2.0, a 350M model with Apache-2.0 license

Pinkstack has released Fijik 2.0, a 350-million-parameter language model based on Granite 4 350M. The model was continually pre-trained on approximately 6 billion tokens with an August 2025 knowledge cutoff and post-trained on a custom supervised fine-tuning corpus.

• It uses the Apache-2.0 license, contrasting with the custom license of LFM2.5.
• The release includes BF16 and GGUF formats available on Hugging Face.
• The author notes that due to the small parameter count, the model is best used with web search tools.

The release provides an open-license alternative for users seeking a nano-sized model capable of reasoning tasks.
