Are you bored of using Chub’s free-tier LLM but don’t want to subscribe to access their other models? Or is your character forgetting important details during roleplay, and you want to use a larger context size? Then it’s time to start using DeepSeek on Chub.
Chub’s in-house default LLM is free to use and has no usage limits or filters, which is great. However, its context size (memory) is limited, and its responses become repetitive and boring fairly quickly.
Why Use DeepSeek On Chub?
Other larger LLM models, like DeepSeek, are trained on a broader range of data. They have larger context sizes (memory), generate more creative responses, and follow instructions more effectively. You can enhance your roleplaying experience by using DeepSeek on Chub.
What Is DeepSeek?
DeepSeek is a Chinese AI company that has created several open-source LLMs, including DeepSeek R1, DeepSeek V3.1, and DeepSeek V3.2, which is their latest model.

The release of DeepSeek-R1 in early 2025 shook the AI world, as it was an open-source reasoning model developed at a lower cost than other LLMs. Its performance also matched top-tier models like OpenAI’s GPT-4 in reasoning and coding tasks.
What Are The Different DeepSeek Models?
DeepSeek R1 is designed for complex problem-solving and explains its chain of thought (CoT) before answering, which helps it generate better responses. In contrast, DeepSeek V3 is a chat model created for simple tasks and does not reason before replying.
On August 21, 2025, DeepSeek launched DeepSeek V3.1, a hybrid model that supports both thinking and non-thinking modes. On September 29, 2025, DeepSeek launched DeepSeek V3.2 with DSA, significantly improving long-context training and inference efficiency with minimal impact on output quality.
While you can still use DeepSeek’s older models from other providers, DeepSeek has replaced them with its new V3.2 model on its official API.
Use DeepSeek On Chub Via The Official API [Paid]
You can use DeepSeek on Chub directly through the official API. To get started, you need to deposit a minimum of $2 into your DeepSeek account. DeepSeek deducts funds from your account balance based on token usage (input and output).

DeepSeek used to offer special discounted hours (off-peak pricing), during which prices dropped by up to 75 percent. They stopped offering discounted hours after September 5th, 2025. Even without the discounted hours, the official DeepSeek API remains the most affordable paid option if you value stability, speed, and quality.

What Is OpenRouter?
OpenRouter is a proxy service that offers a unified interface for accessing different free and paid LLM models. OpenRouter does not host any LLMs; it intelligently routes your requests through one of its multiple providers.
Why Use OpenRouter On Chub?
Larger LLM models are trained on a broader range of data. They have larger context sizes, generate more creative responses, and follow instructions more effectively. You can enhance your roleplaying experience by using OpenRouter to access more advanced LLM models.
Increased Context Size
Context Size refers to the number of tokens (data) that the LLM references when generating a response. In simple terms, it’s your AI character’s memory. A larger context size allows your AI character to remember more details of your conversation.
However, even models that can handle larger context sizes struggle to stay coherent past a certain point. The optimal context size range is between 8,192 and 16,384 tokens.
Creative Writing
Chub’s free-tier LLM tends to be repetitive and reuses phrases too often. While this is common with all LLMs, larger models are trained on more data and don’t feel as repetitive or boring during extended roleplaying sessions.
Faster Responses
In most cases, your responses will generate faster when using OpenRouter on Chub compared to their free-tier LLM. If you’re using a free model, you might encounter issues like slow responses or network errors during periods of high traffic.
Better Custom Prompts
While you can use custom prompts with Chub’s free-tier LLM, other models are better at following instructions. You can also use a custom prompt with a higher token count without worrying about it affecting your AI character’s memory.
Roleplay With More Characters
You can enhance your roleplay experience with characters that have over 1,500 permanent tokens, such as character personality and scenario. When using Chub’s free-tier LLM, these permanent tokens use about 50% of the context size.
Troubleshooting API Errors On Chub
If you encounter issues or errors after setting up an API or Proxy on Chub, you can seek help through their official subreddit or Discord server.
