DeepSeek is known for dramatically lower pricing. Here is how the numbers break down across all models from each provider.
On average, DeepSeek models cost 95% less on input and 97% less on output compared to OpenAI models. At scale, this translates to significant cost savings for teams processing millions of tokens per day.
How many models from each provider support each capability.
DeepSeek has emerged as one of the most formidable open source challengers to OpenAI's ChatGPT line. Founded in China, DeepSeek made headlines with the release of DeepSeek R1, a reasoning-focused model that competes directly with OpenAI's o1 and o3 series, and DeepSeek V3, a general-purpose model rivaling GPT-4o in benchmarks at a fraction of the cost.
The key differentiator is pricing and openness. DeepSeek models are open source (or open-weight) with permissive licenses, meaning teams can self-host, fine-tune, and deploy without vendor lock-in. Meanwhile, their API pricing consistently undercuts OpenAI by 97%+ on average, making them an attractive choice for cost-sensitive production workloads.
OpenAI (ChatGPT) maintains advantages in ecosystem maturity, enterprise features, and breadth of model offerings. With 61 models across multiple specializations (reasoning with o-series, multimodal with GPT-4o, lightweight with GPT-4o Mini), OpenAI offers a comprehensive suite backed by extensive documentation, enterprise SLAs, and a massive developer ecosystem.
For teams deciding between DeepSeek and ChatGPT, the choice often comes down to cost vs. ecosystem. DeepSeek wins on raw cost efficiency and open source flexibility. OpenAI wins on breadth of features, enterprise readiness, and the broader ChatGPT ecosystem including plugins, custom GPTs, and first-party integrations.
