# DeepSeek models on GPTProto > One GPTProto API key covers every model listed below. Text models share an OpenAI-compatible API — swap the `model` id. Image / video / audio models use a submit-and-poll API; follow each model's own llms.txt. ## Overview - **Models**: 7 - **Vendor**: DeepSeek - **Base URL**: `https://gptproto.com/v1` - **Provider page**: https://gptproto.com/model/deepseek ## Authentication Every request needs a GPTProto API key in the `Authorization` header. Create one at https://gptproto.com/dashboard/api-key, then export it: ```bash export GPTPROTO_API_KEY="your-api-key" ``` Header: `Authorization: Bearer $GPTPROTO_API_KEY`. Use `base_url` `https://gptproto.com/v1` with any OpenAI-compatible SDK. ## Text models Call these with the OpenAI-compatible Chat Completions (or Responses / Messages / Gemini) endpoints. Change only the `model` field. | Model ID | Name | Context | Input / 1M | Output / 1M | Guide | | --- | --- | --- | --- | --- | --- | | `deepseek-flash` | DeepSeek Flash | — | $0.3 | $1.2 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-flash/llms.txt) | | `deepseek-v4-flash-vision-exp` | DeepSeek v4 Flash Vision Exp | 1.05M | $0.3 | $1.2 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-v4-flash-vision-exp/llms.txt) | | `deepseek-v4-flash` | DeepSeek v4 Flash | 1.05M | $0.3 | $1.2 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-v4-flash/llms.txt) | | `deepseek-v4-pro` | DeepSeek v4 Pro | 1.05M | $1.12 | $3.37 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-v4-pro/llms.txt) | | `deepseek-v3.2` | DeepSeek v3.2 | 164K | $0.168 | $0.252 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-v3.2/llms.txt) | | `deepseek-v3` | DeepSeek v3 | — | $0.1622 | $0.6487 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-v3/llms.txt) | | `deepseek-r1` | DeepSeek R1 | 64K | $0.33 | $1.31 | [llms.txt](https://gptproto.com/model/deepseek/deepseek-r1/llms.txt) | ## Additional resources - [Provider page](https://gptproto.com/model/deepseek) - [All models](https://gptproto.com/model) - [API keys](https://gptproto.com/dashboard/api-key) - [Platform overview for LLMs](https://gptproto.com/llm-full.txt) - Per-model guide: `https://gptproto.com/model/{vendor}/{model}/llms.txt`
