Frequently Asked Questions
Which is cheapest: GPT-5, Claude, or Gemini?
Google Gemini is the cheapest overall. Gemini 2.0 Flash Lite at $0.075/$0.30 per 1M tokens is the cheapest model from any of the three providers. For budget models, Gemini Flash Lite is 95% cheaper than Claude Haiku 4.5 ($1/$5) and 70% cheaper than GPT-5 mini ($0.25/$2). At the mid-tier, GPT-5 ($1.25/$10) is cheaper than both Gemini 2.5 Pro ($1.25/$10, tied) and Claude Sonnet 4 ($3/$15).
What is the cheapest model from each provider?
OpenAI: GPT-4o mini at $0.15/$0.60 per 1M tokens (or GPT-oss 20B at $0.08/$0.35). Anthropic: Claude Haiku 4.5 at $1/$5 per 1M tokens. Google: Gemini 2.0 Flash Lite at $0.075/$0.30 per 1M tokens. Google wins on budget pricing with the cheapest model overall.
Which has the biggest context window: GPT-5, Claude, or Gemini?
Gemini and Claude both offer 1M token context windows at mid-tier prices. Gemini 2.5 Pro and Gemini 3.1 Pro both have 1M context. Claude Sonnet 4.6 and Claude Opus 4.7 also have 1M context. GPT-5 has 272K context, while GPT-5.5 has 1M. For long-context tasks on a budget, Gemini 2.0 Flash offers 1M context at just $0.10/$0.40 per 1M tokens.
GPT-5 vs Claude Sonnet 4 vs Gemini 2.5 Pro: which should I choose?
GPT-5 and Gemini 2.5 Pro are tied at $1.25/$10 per 1M tokens. Claude Sonnet 4 costs more at $3/$15. GPT-5 has 272K context, Gemini 2.5 Pro has 1M context, and Claude Sonnet 4 has 200K. If you need large context on a budget, Gemini 2.5 Pro is the best value. If you prefer OpenAI's ecosystem, GPT-5 offers similar pricing. Claude Sonnet 4 costs 140% more on input but may offer better instruction-following for specific tasks.
Can I mix GPT-5, Claude, and Gemini in the same application?
Yes, a multi-model strategy is the most cost-effective approach. Route simple tasks to budget models (Gemini Flash Lite at $0.075/M or GPT-4o mini at $0.15/M), complex reasoning to premium models (GPT-5 or Claude Sonnet 4), and long-context tasks to models with 1M windows (Gemini 2.5 Pro or Claude Sonnet 4.6). This typically reduces costs by 50-70% compared to using a single premium model for everything.
