Released January 202433K context≈ 24,576 words1.8B params

A compact conversational model that punches within its weight class — handling everyday dialogue and simple Q&A with reasonable fluency for its size. At 1.8B parameters, it makes real trade-offs: complex reasoning, long-context coherence, and nuanced instruction-following are noticeably limited compared to larger siblings. Think of it as a lightweight workhorse suited for constrained environments where memory and compute matter.

Glossary

CoherenceThe quality of maintaining consistent meaning and logical flow across multiple sentences or exchanges in a conversation.Complex ReasoningThe ability to work through multi-step problems, analyze nuanced information, and draw logical conclusions.Context CoherenceThe ability to maintain consistent meaning and logical flow when processing long sequences of text or conversation.Conversational ModelA language model specifically trained and optimized to engage in multi-turn dialogue with users.Instruction-FollowingThe ability of a model to understand and execute specific tasks or commands given in natural language prompts.Long-ContextThe ability of a model to process and understand very long sequences of text while maintaining coherence across distant parts of the input.ParametersThe learned numerical values in a model — more parameters generally means more capacity but higher compute cost.ReasoningThe model's ability to work through multi-step logical problems and provide justified answers rather than just pattern-matching.
