ChatGPT vs Gemini
Two product families, side by side — subscriptions, API pricing, and which one to reach for.
The short answer
ChatGPT leads on raw capability — its strongest model, GPT-5.6 Sol, posts the higher combined coding and reasoning score in this comparison. Gemini is the cheaper way in: Gemini 2.0 Flash blends to $0.19 per million tokens, which is what matters once you are running volume rather than evaluating. Gemini offers the wider context window at 2M tokens. Most teams end up using both — one for the hard problems, one for everything else.
ChatGPT
OpenAI's consumer product and the most widely used AI assistant. Strongest on multimodal breadth — voice, image generation, browsing, and agent tooling all ship in the same subscription. The API line-up spans a full frontier-to-budget ladder on one 1.05M-token context.

Subscriptions
What ChatGPT and Gemini charge a person per month.
The paid tiers land at $20/month for ChatGPT and $20/month for Gemini. At that price the deciding factor is rarely raw intelligence — both clear the bar for everyday work. It is the surrounding features and the usage ceiling that differ, so pick on what you actually hit limits doing.

ChatGPT and Gemini line-ups matched by capability tier.
| Tier | ChatGPT | Gemini |
|---|---|---|
| Flagship | GPT-5.6 Sol$5.00 / $30.00 per 1M in / out | — |
| Mid-range | GPT-5.6 Terra$2.00 / $12.00 per 1M in / out | Gemini 3.1 Pro$2.00 / $12.00 per 1M in / out |
| Budget | GPT-5.6 Luna$0.20 / $1.20 per 1M in / out | Gemini 2.0 Flash$0.10 / $0.40 per 1M in / out |
At 10M + 2M tokens a month — a realistic mid-size production workload — the cheapest option from ChatGPT (GPT-5.6 Luna) runs about $4.40, against roughly $1.80 for Gemini's Gemini 2.0 Flash. Run your own numbers on the calculator before committing: the mix of input to output tokens moves this more than the headline price does.
Which one to pick
- For the hardest reasoning and long agentic runs: ChatGPT, specifically GPT-5.6 Sol.
- For high-volume production where cost dominates: Gemini, specifically Gemini 2.0 Flash at $0.19 blended per million tokens.
- For whole-repository or long-document work: Gemini, with up to 2M tokens of context.
