Migrating to Olmo 3 32B Think

Coming from OpenAI or another gateway? On an OpenAI-compatible setup the only changes are base_url → https://api.datallmlab.com/v1 and model → allenai/olmo-3-32b-think. Messages, streaming and the rest of your code stay the same. Routing & failover guide.

Self-host or use the API?

Olmo 3 32B Think ships open weights (allenai/Olmo-3-32B-Think, ~9.2K downloads and 171 likes in the last 30 days), 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 multiple 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.
