Introduction to PaLM 2 – What Makes This AI Special?

Before we get into accessing PaLM 2, let‘s briefly go over what makes this model so advanced. Google touts PaLM 2 as a "milestone in AI" – so what exactly can it do?

PaLM 2 Stats and Capabilities

• Parameters: 137 billion (vs. GPT-4‘s 175 billion)
• Training data: 1,000x smaller dataset than GPT-4
• Tasks: Translation, summarization, conversation, programming
• Speed: 2x faster response than GPT-4
• Languages: Support for over 100 languages

According to Google‘s AI researchers, they used a technique called sparse training to train PaLM 2 to be extremely efficient. This allowed it to reach high performance with significantly less training data and fewer parameters than other models.

Specifically, PaLM 2 is adept at core natural language tasks like understanding the context of passages. It also exceeds other models in areas like computer programming thanks to training on GitHub data.

Google focused on making PaLM 2 factually grounded – able to admit when it lacks knowledge about a topic. This emphasis on honesty aims to make the model more trustworthy.

Let‘s now dive into the various ways you can access PaLM 2 and see these capabilities for yourself.

Chat with the Conversational PaLM 2 through Google‘s Bard

One of the easiest and most engaging ways to interact with PaLM 2 is through Google‘s Bard chatbot.

Bard is Google‘s conversational AI service, which employs PaLM 2 to have nuanced discussions on any range of topics. Think of it like chatting with a real person!

Google has upgraded Bard to specifically utilize PaLM 2, letting everyday users try the model in a friendly chat environment.

Here are step-by-step instructions to start accessing PaLM 2 through Bard:

1. Go to https://bard.google.com – This is the official website for the Bard service.

2. Sign up for a free Google account – If you don‘t already have a Google account, you‘ll need to quickly create one.

3. Start chatting – Once signed in, you‘ll see a chat interface. You can now start querying PaLM 2!

4. Ask questions naturally – Pose questions as you would to a knowledgeable friend. For example:

   • What is the significance of Van Gogh‘s Starry Night?
   • Can you suggest honeymoon destinations for a couple that enjoys hiking?
   • How do I make lemon meringue pie from scratch?

5. Explore different types of queries – Get a sense of PaLM 2‘s breadth by asking it to:

   • Summarize a long research paper or news article
   • Translate a text excerpt into another language
   • Explain a complex concept like blockchain
   • Suggest fun weekend activities in your city
   • Discuss philosophical questions or ethical dilemmas
   • Generate code in languages like Python, JavaScript
   • And more – get creative!

6. Provide feedback – Let Google know if Bard‘s responses seem honest, helpful, and factually accurate. Your feedback will improve the AI.

Chatting with Bard gives you conversational access to PaLM 2, one of the most advanced language models ever created. Take advantage of this friendly interface to explore the future of AI!

Note that given high demand, Google may limit access to Bard or place you in a queue. Keep trying!

Utilize PaLM 2 Through Google‘s Med-PaLM and Health Tools

In addition to the conversational Bard agent, Google has created Med-PaLM – a version of PaLM 2 specifically trained on medical data.

Med-PaLM demonstrates how PaLM 2 can gain in-depth expertise when trained on niche datasets. This medical-focused model can understand and generate knowledgeable responses on health topics.

While Med-PaLM is currently limited to researchers, you can still access some of its medical capabilities through Google‘s health tools:

• Google Health Studies: This research app provides health insights powered by Med-PaLM. For example, it can estimate your risk for conditions like heart disease based on your profile.

• Google Health search: Try searching for symptoms, conditions, or medications. You may see informational panels generated by Med-PaLM.

• Google Lens: Use your phone‘s camera and Google Lens to scan things like rashes or moles. Med-PaLM can provide analysis on potential conditions.

Testing out these tools gives a glimpse of how PaLM 2 models can specialize for certain domains like medicine. While not full access to Med-PaLM, it showcases the knowledge PaLM 2 can gain when trained on niche datasets.

Google may open up Med-PaLM access more broadly in the future as they continue advancing healthcare AI.

Await API Access to Deeply Integrate PaLM 2 into Apps

The most robust way for developers to access PaLM 2 is via API (application programming interface).

Google announced they will release a PaLM 2 API in 2024. This would allow programmatically integrating PaLM 2 into third-party applications.

The API will enable sending text prompts to PaLM 2 and receiving generated responses. This opens exciting possibilities:

• Build custom AI apps powered by PaLM 2 as the backbone.

• Add PaLM 2‘s capabilities like summarization into existing products.

• Research the model by analyzing its outputs at scale.

• Create hybrid AI systems combining PaLM 2‘s strengths with other models.

• Optimize queries and integrate PaLM safely into public products.

While Google has not set an exact API release date, interested developers can sign up on the waitlist for access.

Once available, the API will likely require applying for limited access as quotas expand over time.

Here is an example PaLM 2 API request and response:

API Request:

{
  "prompt": "Write a Python program to calculate the area of a circle given radius 5."
}

API Response:

{
  "response": "Here is a Python program to calculate the area of a circle with radius 5:\n\nimport math\n\nradius = 5\narea = math.pi * radius ** 2\n\nprint(‘The area is:‘, area)"
}

As you can see, the API allows harnessing PaLM 2‘s code generation abilities. The possibilities are endless!
