Detailed analysis
Intelligence & Reasoning
Winner: Claude Opus 4.7 (Fast)Claude Opus 4.7 (Fast) scores 53.5 on intelligence index versus Gemini's 25, reflecting stronger nuanced and careful reasoning. Gemini's lite design explicitly trades peak capability for speed and may need more guidance on complex tasks.
Speed & Latency
Winner: Gemini 3.1 Flash LiteGemini 3.1 Flash Lite outputs at 286.39 tokens per second, nearly six times faster than Claude's 50.36 t/s. This makes Gemini the clear choice for low-latency multimodal applications.
Pricing
Winner: Gemini 3.1 Flash LiteGemini costs $1.5 per million tokens while Claude costs $150 per million, a 100x difference. The price gap strongly favors Gemini for high-volume usage.
Context Window
Winner: Gemini 3.1 Flash LiteGemini provides 1,048,576 tokens versus Claude's 1,000,000. Both handle large contexts effectively, but Gemini's edge is minor and both list large-context handling as a strength.
Claude Opus 4.7 (Fast)
Pros
- +Strong safety alignment
- +Nuanced and careful reasoning
- +Effective large-context handling
Cons
- –May decline edge-case or risky requests
- –Multimodal tasks can increase response time
- –Large context usage remains resource-heavy
Gemini 3.1 Flash Lite
Pros
- +High speed and low latency
- +Handles very large context windows
- +Broad modality support in a lightweight package
Cons
- –Reduced depth on highly complex reasoning tasks
- –Lite design trades peak capability for speed
- –May require more guidance on nuanced or creative outputs
Summary: Claude Opus 4.7 (Fast) vs Gemini 3.1 Flash Lite
Choose Gemini 3.1 Flash Lite for speed-critical, cost-sensitive multimodal workloads with very large contexts. Choose Claude Opus 4.7 (Fast) when maximum intelligence and careful reasoning outweigh the steep price and slower speed. The models target different priorities rather than direct overlap.
