Our take
AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.
MythoMax 13B is a text-only model by Gryphe, listed in the OpenRouter catalog as a popular Llama 2 13B fine-tune. Its model card describes it as a tensor-level merge of MythoLogic-L2 and Huginn, built for roleplay and storywriting, using Alpaca-style prompts, with an 8192-token context and a June 2023 knowledge cutoff. The sources contain no independent benchmark results, so capability claims are author- and catalog-reported and should be validated on real workloads before adoption.[1][2]
Strengths
- Designed for roleplay and storywriting according to its model card and the OpenRouter catalog description.[1][2]
- Combines MythoLogic-L2 and Huginn via a per-tensor merge intended to pair strong comprehension with strong writing output.[2]
- Offers an 8192-token context, Alpaca-style prompting, and community quantized builds (GGUF, GPTQ, AWQ) noted in the model card.[1][2]
Limitations
- No benchmark scores or independent evaluations appear in the sources, so reported quality is unmeasured and needs workload validation.[1]
- Knowledge cutoff is June 2023, and the author himself suggests the model is being superseded after Llama 3's release.[1][2]
- The license is listed only as 'other' without details, and the model is strictly text-to-text.[1][2]

Tasks and capabilities
A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.
| Task | Grade | Source-declared capability |
|---|---|---|
| General quality | No measurement | — |
| Coding | No measurement | — |
| Agents | No measurement | parameters: structured_outputs |

How grades work
Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.
- S — S — top 10% of the cohort
- A — A — next 20% of the cohort
- B — B — next 30% of the cohort
- C — C — below the B band
