Gemini 2.5 Pro is the price-to-quality leader at the frontier. Reasoning is within a hair of GPT-5, web-search-grounded factuality is the best in the category, and the native multimodal support (audio + video in, text out) is uniquely good.
Pricing is the cheapest of the three frontier models. Context is 2M tokens - even larger than Claude.
Where it trails: tool use is a step behind GPT-5; agentic reliability still has rough edges.
Verdict: best value at the frontier. 9.0/10.
