MythoMax 13B
MythoMax 13B is a text-only model from Gryphe with a 4,096-token context window and a matching 4,096-token output ceiling. It accepts text input and produces text output, with no support for tool calling, reasoning modes, or structured output. The context limit is modest by current standards, so tasks requiring long documents or extended multi-turn sessions will run into the ceiling quickly. At $0.06 per million tokens on both input and output, it sits at the low end of the pricing spectrum, which is its clearest selling point. However, there is currently no independent benchmark coverage to verify how it performs on reasoning, instruction following, or factual accuracy tasks. Buyers who need proven, measurable quality should look elsewhere until coverage appears; those running low-stakes creative or conversational workloads on a tight budget may find the price worth a trial.
