Model Detail
Mythos-nano
—Mythos-nano is a code generation model with 3B parameters released by squ11z1. The model is registered under the text-generation pipeline tag on Hugging Face, distributed under the permissive mit license.
Mythos-nano ships with 3B parameters. Total weight footprint is approximately 3.1 GB, which is the relevant figure when planning local-inference VRAM. The mit license is permissive, allowing commercial deployment and derivative work without per-seat fees, though attribution requirements still apply.
Mythos-nano is best fit for code completion, repository-scale Q&A, and pair-programming integrations. It is a less obvious choice for one-shot generation of security-critical code without review. Treat this as a starting matrix rather than a benchmark verdict — the right deployment usually depends on the specific evaluation suite that mirrors your workload.
