MythoMax 13B
MythoMax 13B from gryphe is a powerful text-based AI model with an impressive context length of 8192 tokens and can generate up to 3686 completion tokens at once. However, it does not support tools or reasoning capabilities nor provides structured output, limiting its utility in complex tasks. Given its moderate pricing of $0.06 per million input and output tokens, MythoMax 13B is a viable option for those primarily needing text-based responses within the constraints mentioned. While lacking independent benchmark coverage, it remains a cost-effective choice for users seeking basic text generation without advanced reasoning or structured outputs.
