Prompting tips for Granite 4.0 Micro

• Be explicit and show the shape of the answer. Spell out format, tone and constraints up front, and include one short example of the output you want — Granite 4.0 Micro follows concrete instructions better than abstract ones.
• Constrain JSON with a schema. Use response_format / structured outputs rather than "reply in JSON" to get valid, parseable objects every time.
• Cheap enough to batch. Great for high-volume classification, extraction and drafting — template the prompt, batch requests, and validate outputs programmatically.

Tips are derived from Granite 4.0 Micro's actual capabilities — context window, tool & JSON support, modality and price tier — not generic advice.

Migrating to Granite 4.0 Micro

Coming from OpenAI or another gateway? On an OpenAI-compatible setup the only changes are base_url → https://api.datallmlab.com/v1 and model → ibm-granite/granite-4.0-h-micro. Messages, streaming and the rest of your code stay the same. Routing & failover guide.

Self-host or use the API?

Granite 4.0 Micro ships open weights (ibm-granite/granite-4.0-h-micro, ~8.5K downloads and 147 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 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.
