Migrating to WizardLM-2 8x22B

Coming from OpenAI or another gateway? On an OpenAI-compatible setup the only changes are base_url → https://api.datallmlab.com/v1 and model → microsoft/wizardlm-2-8x22b. Messages, streaming and the rest of your code stay the same. Routing & failover guide.

Self-host or use the API?

WizardLM-2 8x22B ships open weights (microsoft/WizardLM-2-8x22B), with community quantizations (bf16) for smaller GPUs, so you can run it yourself. Most teams still use the API: no GPU to provision or keep warm, no inference ops, and instant access across 1 providers with automatic failover. Self-host when data residency or fixed per-token economics matter most.

Rate limits & reliability

Rate limits here are the DataLLM Lab gateway's, not the upstream vendor's. On 429 (rate limited) or 503 (provider busy), retry with exponential backoff. See the error-code guide and failover setup.
