• Footnotes:

The team at WRITER is thrilled to announce the release of three new open models in the Palmyra-mini family. These models are designed to be powerful, lightweight, and highly performant for their size (1.5B to 1.7B), making them ideal for a wide range of applications with efficient inference.

• palmyra-mini: A powerful, lightweight non-thinking base model.
• palmyra-mini-thinking-a: A specialized variant optimized for complex reasoning and logic.
• palmyra-mini-thinking-b: Another specialized variant that excels at mathematical equations and reasoning.

The "thinking" models have been trained with a Chain of Thought (CoT) approach, which improves their reasoning abilities. We're excited to see what the community will build with these new models!

GGUF and MLX quantizations are also available for your convenience:

• palmyra-mini-GGUF

• palmyra-mini-thinking-a-GGUF

• palmyra-mini-thinking-b-GGUF

• palmyra-mini-MLX-BF16

• palmyra-mini-thinking-a-MLX-BF16

• palmyra-mini-thinking-b-MLX-BF16

Benchmark Highlights:

• palmyra-mini: Our non-reasoning improved base model, delivering a score of 52.6% on Big Bench Hard (get-answer)(exact_match), making it a fantastic all-rounder for a wide variety of generative tasks.

• palmyra-mini-thinking-a: This variant is your go-to for complex logical challenges. Trained with a Chain of Thought (CoT) approach, it achieves an impressive 82.87% on GSM8K (strict match), demonstrating its powerful reasoning capabilities. It has the highest overall average score on benchmarks relative to other models in the release.

• palmyra-mini-thinking-b: Pushing the boundaries of problem-solving, this model scores a solid 92.5% on AMC23. It's a great choice when you need a model that can "think" its way through demanding tasks. This has the highest average benchmark scores in the benchmarks AIME24,AIME25, GPQA, HMMT25, HLE, MMLU_PRO,MATH500, LCB relative to the other models in the release.
