Detailed analysis
Intelligence
Winner: Claude Fable 5Claude Fable 5 scores 59.9 on the intelligence index compared to Gemini 3.1 Flash Lite's 25. This gap favors Claude for complex reasoning and detailed analysis. Gemini's lite design explicitly trades peak capability for speed.
Speed & Pricing
Winner: Gemini 3.1 Flash LiteGemini 3.1 Flash Lite delivers 296.2 t/s output speed at $1.5 per 1M tokens. Claude Fable 5 lists no speed figure and costs $50 per 1M tokens. The price and speed advantage is decisive for high-volume or real-time use.
Context & Modalities
Winner: TieBoth models offer roughly 1M-token contexts (1,000,000 vs 1,048,576). Claude excels at text-visual integration and file reasoning but lacks native audio or video. Gemini provides broader modality support including video in its lightweight design.
Limitations
Winner: TieClaude may decline edge-case requests and slows at maximum context lengths. Gemini shows reduced depth on complex reasoning and may need more guidance for nuanced outputs. Each limitation directly offsets the other's primary strength.
