Is DeepSeek's relationship advice unique? A thorough comparison with ChatGPT and Gemini.

Love advice from AI? DeepSeek, ChatGPT, and Gemini — I asked them questions about romance and compared their answers. See how each AI would confess — and the differences among them.

Comparing AI Answers

To verify how AI offers different advice, we conducted a test where the same romance-related question was posed to multiple AIs and their responses were compared. The reason for this approach is that love is a universal experience across cultures, providing a broad, representative sample. By visualizing how responses vary due to AI algorithms and training data, we hoped to reveal each AI’s personality and characteristics.

This time, we compared three AIs — ChatGPT, DeepSeek, and Gemini — by posing the same romance advice question to each. We expect that examining differences in response style and guidance direction will offer clues about each AI’s features and learning methods.

As the test method, we began with a scenario of a college student seeking romance advice and fed the exact same prompt to each AI. Specifically, we started with a simple question like “I have someone I’m interested in — how should I approach her?”, and added questions to progress the story. This method aims to clarify how the AI handles consistency and changing circumstances of the person asking for advice.

Furthermore, since romance relies heavily on emotional dynamics, we also considered how well each AI shows empathy and offers practical guidance. In addition to differences in advice, we expected to observe each AI’s cultural background and learning-data-driven tendencies reflected in their responses.

DeepSeek’s Answers

DeepSeek tends to prioritize action, maintaining a stance that the seeker should “take some kind of action.” It frequently suggests concrete actions, such as “write a letter,” “give a anonymous gift,” or “edit a video to present as a gift.” While other AIs may advise “give some space first” or “think calmly,” DeepSeek emphasizes proactive movement.

It also features strong strategic thinking, with tendencies to plan actions step by step, such as “eye contact tests,” “analyzing signs of recovery,” and “a confession flowchart.” It also holds perspectives like “unread vs. read status is information warfare” and “leave an impression that overwrites memory,” reflecting a unique romantic viewpoint not seen in other AIs.

However, some of its actions can come across as extreme. For example, suggestions like “on a rainy day, don’t use an umbrella and adjust your coat,” “store her missed ball in an acrylic case,” or “write and compose a circular song” may be hard to accept in reality.

DeepSeek vs Gemini

Comparing DeepSeek and Gemini reveals several distinctive differences.

DeepSeek provides strategic and concrete action guidelines, thoroughly applying psychological techniques and situational analysis. It uses approaches that combine psychological warfare and action strategy, such as “two weeks of silence,” “utilizing circle dynamics,” and “shadow support operations.”

Gemini, on the other hand, emphasizes honesty, communication, and effort in practice, offering simple, actionable advice like “start by talking to her,” “work hard on tennis,” and “express gratitude.”

DeepSeek details when and how to act, presenting a clear plan step by step, such as “after the match, implement two weeks of silence to reset impressions” or “improve indirectly by maintaining court upkeep.”

Gemini provides guidance on what to do but offers fewer specifics on timing or scenarios. It often stops at indicating the direction of action, e.g., “talk to her when she’s alone,” or “perhaps practice a bit before the match, if you’d like.”

DeepSeek thoroughly contemplates contingency, proposing reverse strategies like “ghostly service” or “polish the ball and attach a supportive sticker,” and editing a video of her play to hand to her.

In contrast, Gemini recommends “reflect and move on,” emphasizing sincere handling: “calmly organize the situation,” “express gratitude and sincerity to her,” and “respect her feelings.”

Compared with ChatGPT

ChatGPT emphasizes a sincere, logical approach and prioritizes the seeker’s emotional stability. It repeatedly stresses that you should “not rush and respect her feelings,” advising against forced approaches. It values human-relations perspectives over romantic games, and it urges careful judgment regarding timing for confessions.

Compared with the other AIs, ChatGPT strongly focuses on self-esteem, often including encouraging phrases like “You are not a terrible person.” While DeepSeek offers strategic approaches and Gemini prioritizes healthy communication, ChatGPT promotes building genuine relationships and advises taking actions calmly and patiently.

However, ChatGPT does not engage in romantic games or psychological warfare and does not provide concrete strategic steps like DeepSeek. Because it emphasizes “honesty” and a “calm approach,” those seeking game-like tactics may find its responses lacking. It also leaves final judgments to the seeker, and does not give a definitive answer to “Should you confess?” instead urging to “think carefully and decide.”

Overall, ChatGPT’s responses prioritize mental support and relationship management, recommending careful and sincere handling without delving into strategic romance techniques. It helps the seeker calmly assess the situation to arrive at the best possible choice.

Summary: Differences in AI Training Data and Their Impact

These differences likely stem from how each AI was trained. ChatGPT learns from vast big data to provide general knowledge and experience-based guidance across broad contexts. DeepSeek appears to incorporate knowledge-base learning rooted in Chinese cultural context, emphasizing strategic and analytical approaches to romance. Gemini, developed by Google, reflects Western values and tends to offer simple, positive advice. These training-method differences are evident in the styles of romantic guidance each AI provides.

From this exploration, it seems ChatGPT tends to deliver neutral, safe, and steady responses; while DeepSeek can be highly concrete and sometimes extreme, including suggestions like filming her play in 4K and editing a video message saying “I love your tennis,” which may be hard for many Japanese readers to grasp. Cultural differences may account for some of these, and in some cases such suggestions could be perceived as excessive actions.

Is AI in恋愛相談 (romance advice) Difficult?

There are skeptical opinions about whether AI can handle romance advice. Romance is greatly influenced by relationships with others, and countless patterns arise from personality and circumstances. Therefore, deriving a single correct answer is difficult, and it may remain unsolved for centuries.

For example, many love-related poems exist in classical anthologies, and people have struggled with romance for centuries. Given this long history, AI finding a perfect optimal solution is unlikely. However, each AI has its own personality and strengths in offering different perspectives. Understanding each AI’s characteristics and not overly trusting any single advice is wise, enabling you to choose actions that fit you best.
