Deep dive
The capability footprint differs most on vision: Gemini 3.1 Flash Lite Preview, multimodal input: Gemini 3.1 Flash Lite Preview, function calling: Gemini 3.1 Flash Lite Preview, tool use: Gemini 3.1 Flash Lite Preview, structured outputs: Gemini 3.1 Flash Lite Preview, and code execution: Gemini 3.1 Flash Lite Preview. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
Pricing coverage is uneven: Gemini 3.1 Flash Lite Preview has $0.25/1M input tokens and RWKV-7 Goose 1.5B has no token price sourced yet. Provider availability is 4 tracked routes versus 0. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Gemini 3.1 Flash Lite Preview when coding workflow support and broader provider choice are central to the workload. Choose RWKV-7 Goose 1.5B when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
