What is Gemini? Features, Differences from ChatGPT and Claude, and Comparison of Translation Ability and Accuracy!

1. What is Gemini?

 

Gemini is an AI model developed by Google DeepMind. It was created not just as a chatbot or search assistant, but as a "multimodal AI" capable of understanding and integrating multiple forms of information like a human. This AI can interpret not only text but also images, audio, and video, generating context-appropriate outputs. It works in conjunction with various services offered by Google, demonstrating its capabilities as a "smart assistant" in many situations.

1-1. What You Can Do with Gemini

By using Gemini, you can streamline various tasks. Specifically, this includes drafting emails, proofreading texts, analyzing images and charts and generating explanations based on them, assisting with programming and code reviews, and summarizing learning materials. Additionally, it can handle tasks through integration with tools like Google Docs and Spreadsheets, as well as support research on trends and the latest information. These are examples of Gemini's capabilities, and it is expected to be utilized in a wide range of applications, from business support in professional settings to information gathering in daily life.

1-2. Features of Gemini

A major feature that sets Gemini apart from other AIs is its support for "multimodal" capabilities. This refers to the ability to handle multiple types of information simultaneously, not just text but also images and audio. For example, it can combine images with related text to understand content, or link audio data with text information for processing. This is similar to how humans use multiple senses, such as sight and hearing, to capture information and comprehend complex content.

One of Gemini's key strengths is its seamless integration with various services provided by Google. This supports practical tasks such as drafting email replies and organizing tasks based on schedule information. It also has strong multilingual capabilities, delivering natural and accurate responses in many languages, including Japanese and English.

Gemini can handle a large amount of information at once, allowing it to think logically and accurately grasp the context to provide answers. Therefore, it is also capable of analyzing complex discussions and making inferences or proposals based on deep insights into business challenges.

One of the unique features of Google, which excels in search, is the integration of search technology and generative AI. Generative AI sometimes produces uncertain information (so-called hallucinations), but Gemini includes a mechanism that allows users to verify the sources and accuracy of the generated information to mitigate this risk.

2. Commonalities and Differences between Gemini, ChatGPT, and Claude

2-1. Common Points

Generative AIs such as Gemini, ChatGPT, and Claude are artificial intelligences capable of creating new content. These generative AIs are based on large language models (LLMs) trained on vast amounts of text data, enabling them to produce content in various formats including text, images, audio, and code. They feature versatility with the ability to engage in natural, human-like conversations, understand context, and handle a wide range of tasks.

In contrast, other types of AI each have different purposes and capabilities. Analytical and predictive AI specialize in extracting insights and future trends from existing data but do not create new content. Pattern recognition AI excels at identifying patterns in images and audio but does not generate new creations based on those recognitions. Rule-based AI operates according to predefined rules, lacking flexibility and often unable to handle unexpected inputs. Reinforcement learning AI specializes in finding optimal solutions for specific tasks through trial and error but does not possess the creative abilities of generative AI.

The innovative aspect of generative AI is its ability to create entirely new content based on training data and to possess human-like conversational skills. While other AIs mainly focus on data processing and optimizing specific tasks, generative AI demonstrates high capabilities in both understanding and creativity. This difference is one of the reasons why generative AI has rapidly gained popularity in recent years.

2-2. Differences

Gemini was developed by Google DeepMind, Google's AI research division, and Google AI. On the other hand, ChatGPT was developed by OpenAI, an AI research company, and Claude was created by Anthropic, an AI startup.

A major feature of Gemini is its multimodal capability, which allows it to handle various types of information such as text, images, videos, and audio. It is also deeply integrated with services like Google Search and Gmail, excelling in processing large amounts of information and understanding and reasoning through complex problems.

ChatGPT is excellent for programming tasks, supporting structured research, and maintaining tone during translation. Claude is strong in handling advanced text and code, characterized by a natural writing style.

Gemini can sometimes feel awkward in conversation compared to ChatGPT and has limitations in image generation and handling complex tasks. Like other chatbots, it may provide inaccurate information and has biases in its training data. ChatGPT, especially in long conversations, can struggle to remember context and may generate factually incorrect or inappropriate responses. Claude tends to be somewhat less creative and more conservative in its replies compared to ChatGPT. Both Gemini and ChatGPT feature Deep Research capabilities, enabling responses using the latest information and generating reports that integrate dozens to over a hundred sources.

3. Comparing the Translation Capabilities of Gemini, ChatGPT, and Claude!

 

Let's compare the translation capabilities as machine translation engines.

3-1. Comparison of Raw Translations

I executed the translation with a simple prompt: "Translate into Japanese. Output only the translated text." The translations generated by each AI are as follows. Focusing on the translations of "Leading the pack" and "know a thing or two," all AIs avoided literal translations and rendered natural expressions in Japanese; however, considering the business context, Claude used the most appropriate expressions.

Source	Leading the pack was AAA Media Group, followed by BBB Video, and CCC Technologies. DDD Brothers and EEE Wire came in fourth and fifth, respectively. AAA is a highly successful fully remote company with hundreds of employees, so we know a thing or two about building a remote work environment.
ChatGPT	The leader was AAA Media Group, followed by BBB Video and CCC Technologies. DDD Brothers and EEE Wire ranked 4th and 5th respectively. AAA is a highly successful fully remote company with several hundred employees and is confident in building remote work environments.
Gemini	The top was AAA Media Group, followed by BBB Video and CCC Technologies. DDD Brothers and EEE Wire were ranked 4th and 5th respectively. AAA is a very successful fully remote company with hundreds of employees, so they are well versed in building remote work environments.
Claude	AAA Media Group took the lead, followed by BBB Video and CCC Technology. DDD Brothers and EEE Wire ranked fourth and fifth respectively. AAA is a highly successful fully remote company with hundreds of employees and extensive expertise in building remote work environments.

3-2. Comparison of Translations in Natural Japanese

Next, I tried the prompt "Translate into natural Japanese. Output only the translation." ChatGPT's translation changed and improved to the expression "has extensive knowledge." Gemini also changed, but the phrase "has an advantage" feels too formal. Claude said "has sufficient knowledge," which ended up sounding rather awkward.

4. Comparing Translation Quality Regarding Automatic Revision of Fuzzy Matches in the Translation Memory!

 

"Translation memory" is a database that stores the bilingual data of sentences that were translated in the past. By integrating them with computer-assisted translation (CAT) tools, they help improve the quality and efficiency of translation work. When translating similar texts, such as user manuals and other documents that are frequently revised, using a translation memory can significantly reduce translation time. For more details about CAT tools, check out the following post.

What Are CAT Tools? Introducing the Benefits and Drawbacks

"Fuzzy match" refers to cases where the previous source text in the translation memory is similar but does not completely match the new source text being translated. It is also called a partial match. When a document is revised, small parts of the past source text may be changed. For example, in the table below, "DeepL、" has been added to the revised source text. In such cases, the past translation from the translation memory is retrieved, and any changes are manually reflected, using the old translation as a base.

By using generative AI, this reflection task can be automated. Below, we compare the automatically corrected translations by each generative AI.

4-1. Comparison of automatic revision of fuzzy matches in the translation memory

For all of the generative AIs, the revised source text's "DeepL" is correctly reflected in the translation. However, since "Google Cloud Translation API" was singular before the revision, the verbs "is" and "has" were used, but now that it has become plural with "DeepL and Google Cloud Translation API," the verbs need to be changed to "are" and "have." Comparing the translations below, only ChatGPT made this correction properly. Such changes are often overlooked when revising manually, but ChatGPT has appropriately corrected the text to ensure proper English.

4-2. Automatic revision of fuzzy matches in the translation memory + comparison when specifying the glossary

Product names and service names may change. So how might one automatically reflect new terms while utilizing past translation memories? In the following example, we specified that the term "Office add-in" should be written as "Office ADD-IN" and "DeepL" as "DeepLTEST," and automatic revision of fuzzy matches in the translation memory was performed. Comparing the translations from each generative AI, only ChatGPT correctly reflected the terms while also changing the verbs to plural form.
