R1T Chimera

tng-r1t-chimera

TNG-R1T-Chimera is an experimental storytelling-focused LLM derived from the earlier DeepSeek-based Chimera model and available only through Chutes and OpenRouter. It has a friendlier creative personality, higher EQ-Bench scores, stronger intelligence (though slightly slower), clearer separation between reasoning and answers, and better tool calling. The creators also recommend following Microsoft's MAI-DS-R1 usage guidelines when working with the model.
