dolphin-2.9.1-yi-1.5-34b

Processes natural language instructions across code, math, reasoning, and agent tasks using a transformer-based decoder architecture fine-tuned on 7+ specialized datasets (Dolphin, OpenHermes, CodeFeedback, Agent-FLAN). Implements ChatML format for structured multi-turn conversations with explicit function-calling schema support via the Locutusque/function-calling-chatml dataset, enabling the model to generate tool invocations alongside natural language responses.

Generates syntactically correct and semantically sound code across Python, JavaScript, SQL, and other languages through training on CodeFeedback-Filtered-Instruction and dolphin-coder datasets. Uses the Yi-1.5 base architecture's token embeddings to understand code structure, variable scoping, and language-specific idioms, enabling both code completion and code-from-description generation without language-specific tokenizers.

Solves mathematical word problems and performs step-by-step reasoning through training on Microsoft's Orca-Math-Word-Problems-200K dataset. The model learns to decompose complex math problems into intermediate reasoning steps, leveraging the Yi-1.5 base's strong numerical understanding and the Dolphin training's chain-of-thought patterns to produce verifiable mathematical solutions.

Decomposes complex user requests into executable sub-tasks and generates action plans through training on internlm/Agent-FLAN dataset. The model learns to identify task dependencies, prioritize steps, and generate structured action sequences that can be executed by downstream systems, enabling autonomous agent behavior without explicit prompt engineering for each task type.

Maintains coherent multi-turn conversations through ChatML format support and training on Samantha-data and OpenHermes-2.5 conversational datasets. The model tracks conversation history, maintains persona consistency, and generates contextually appropriate responses by leveraging the ChatML message structure (system/user/assistant roles) to explicitly separate conversation turns and context boundaries.

Follows complex natural language instructions with explicit reasoning traces through training on Dolphin-2.9 dataset (curated instruction-following with reasoning explanations). The model generates not just task outputs but also intermediate reasoning steps, enabling users to understand and audit the model's decision-making process. Uses the Dolphin training methodology of pairing instructions with detailed reasoning chains to improve both accuracy and interpretability.
