WizardLM-2 8x22B

A mixture-of-experts model with 8 expert pathways and 22 billion parameters per expert, developed by Microsoft for handling complex reasoning and generation tasks.

Strengths

Handles long contexts up to 65,535 tokens and benefits from the MoE architecture which allows selective routing to relevant experts for efficient processing of diverse tasks.

Best for

Workloads requiring extended context, nuanced reasoning, or varied task types where the model can route to specialized experts rather than activating all parameters.

Limitations

Requires more compute to run than Microsoft's newer Phi models released in 2025, which target smaller form factors and more constrained environments.
