Benchmark scores may vary based on evaluation methodology and conditions.
Impressive performance for self-hosted deployment. Code generation quality is solid. The model is massive but the quality justifies the hardware investment.
Llama 3.1 405B proves open source can compete with the best. Running it locally gives me full control over my data. The community around it is fantastic.
Good general-purpose model but requires significant infrastructure to self-host. For teams with the resources, it is a strong alternative to paid APIs.
