Arcee AI: Trinity Large Thinking
Arcee AI's Trinity Large Thinking model is designed for tasks requiring complex reasoning and structured output. However, according to its profile, it only supports text input modalities, with a maximum context length of 262144 tokens. This model may be worth considering for those looking for a tool that can support reasoning capabilities, but also demands a significant budget. With an input price per million tokens of $0.25 and output price per million tokens of $0.8, it is one of the more expensive options available. Despite a blended benchmark score of 14.4 across one independent benchmark, its standing relative to other models in terms of performance remains uncertain due to limited coverage.
