Decision scorecard

Local evidence first

Signal	Gemini 2.5 Pro	Gemma 7B Instruct	How to read it
Best for	reasoning-heavy apps, multimodal apps, and tool-calling agents	provider-routed production	Use-case synthesis from product type, capability flags, context, and provider data.
Decision fit	Coding, RAG, and Agents	Coding, Classification, and JSON / Tool use	Primary workload tags from local decision data.
Context window	1m	8k	Higher is better when prompts, retrieval chunks, or transcripts are large.
Cheapest output	$10/1M tokens	$0.25/1M tokens	Cheapest tracked provider route; verify your exact region and tier.
Provider routes	4 tracked	8 tracked	Broader coverage can reduce vendor lock-in and fallback risk.
Shared benchmarks	Google-Proof Q&A leader	2 shared	Visible benchmark lead is 35.6 points on Google-Proof Q&A.
