Synthia-S1-27b: Advanced Reasoning and Multimodal AI

Synthia-S1-27b, developed by Tesslate AI, is a 27 billion parameter model based on the Gemma3 architecture. It is specifically fine-tuned for advanced reasoning, coding, and creative writing (roleplay) use cases. This model stands out for its ability to handle complex logical problems and generate nuanced creative content.

Key Capabilities

• Multimodal Input: Supports both text and image inputs, allowing for diverse application scenarios.
• Extended Context Window: Features a large 128K token context window, enabling deep contextual understanding and analysis of extensive information.
• Enhanced Reasoning: Demonstrates significant improvements in reasoning benchmarks, with a 57% score on GPQA Diamond (one-shot) and 75% on MMLU Pro (averaged 15% subset), surpassing Gemma 3 PT 27B.
• Specialized System Prompts: Utilizes distinct system prompts for creative writing, reasoning, and coding to guide its behavior and optimize output quality for specific tasks.
• Coding Proficiency: Trained on extensive programming debugging and solution data, making it highly capable for coding tasks.

Training and Architecture

Synthia-S1-27b is a decoder-only Transformer trained for over 205 hours on an A100 GPU, incorporating multiple rounds of SFT and RL. It uses bf16 precision with int8 quantization. The training objective focused on instruction tuning to emphasize reasoning, coding, and factual accuracy.
