Strengths
- Very strong cost profile for routing, triage, and pre-processing.
- Maintains built-in tool support despite the low price tier.
Things to watch
- Capability ceiling is lower for nuanced coding or planning.
- Best used as part of a routed stack rather than as the only model.
Best for
Research synthesis & analyst workflows
Prioritize source grounding, multilingual reading, long-context reasoning, and a retrieval stack that stays inspectable.
Agent automation & operations
Prioritize tool reliability, composability, secret handling, and robust state management across long-running flows.
