GPT Sol vs Gemini Pro
Sol is the stronger all-round generalist; Gemini 3.1 Pro is the reasoning-benchmark leader at a comparable price, $2 and $12 against Sol's $2 and $10. Both handle roughly a million tokens of context, though only Gemini takes audio natively, so this comes down to modal needs and which cloud you already pay.
