Airtel benefits

On July 17, 2025, Airtel announced a cooperation with Perplexity to provide its 360 million users with a free 12-month Perplexity Pro subscription service. This premium service, originally priced at Rs 17,000, is now available for free for all Airtel users, including mobile, Wi-Fi and DTH users. This is also the first time that Perplexity has cooperated with Indian telecom companies.

Perplexity CEO Aravind Srinivas said:

“This collaboration is an exciting way for more people in India – whether students, professionals, or family managers – to get access to accurate, trusted and professional-grade AI.”

This cooperation is beneficial to both parties: Perplexity can expand its influence with Airtel's huge user base, and Airtel adds attractive added value to its services and achieves a win-win situation.

What is Perplexity Pro?

Perplexity Pro is a premium subscription service launched by Perplexity AI, providing users with enhanced features of its AI-powered search engines. Simply put, this is a search engine powered by artificial intelligence. The core technology of Perplexity Pro is Sonar LLM. Unlike general models such as Gemini 2.5 and ChatGPT 4o, Sonar is designed for fast and real-time information retrieval. In addition, users can also choose a variety of advanced models in Perplexity Pro to improve the user experience. Currently optional models include:

• GPT-4.1 : OpenAI's advanced model, specializing in complex problem solving, especially in programming, instruction compliance and handling long contexts.
• Claude 4.0 Sonnet : Anthropic's high-performance language model provides excellent performance in the accuracy and depth of language understanding, taking into account speed and quality.
• Claude 4.0 Sonnet Thinking : Anthropic's "thinking" model, specializing in deep reasoning and complex pattern recognition.
• Sonar : Perplexity’s self-developed flagship model supports 200,000 context length, optimizes response speed and quality, and integrates web search functions.
• Grok 4 : xAI's latest inference model, performs well in math, science and programming tasks.
• Gemini 2.5 Pro : Google's multimodal generative AI, with powerful inference capabilities and supports text and image processing.
• R1 (1776) : A censored custom model based in the United States, suitable for specific professional scenarios.
• o3 : A model focused on complex analysis and inference tasks, provided alongside other advanced options.

Please note that available models may be adjusted over time, and it is recommended to refer to the official page for the latest list.

Actual experience

To give you a more intuitive understanding of the tool, I will test its performance with several practical tasks and evaluate its competitiveness with similar products. Here are three tasks I will demonstrate:

1. Real-time trend analysis
2. In-depth research
3. Image generation

Note : All the following tasks are completed using the Perplexity self-developed model Sonar.

1. Trend Analysis Task: Explore Real-time Topics

Objective : Research an emerging technology or business trend and extract key insights.

Question : "What is the highest price of Indian gold in 2025? And predict its future trend."

reply :

Assessment : The answer was satisfactory overall. However, because the model relies on online data sources, some outdated information may affect accuracy. Nevertheless, predictions of future trends are reasonable and are within the acceptable range.

2. In-depth research task: In-depth exploration of topics

Objective : Deeply study a trend and refine insights.

Question : "How does artificial intelligence affect the healthcare industry?"

reply :

Evaluation : The answers are of good quality, the content is presented in the form of an article, with clear structure and easy to read. It is more attractive if you can add a chart or infographic.

3. Image generation task: Create complex visual images

Target : Specify image details and generate images.

Asked : "Generate a 'realistic style' image of 'Dora' with a size of 872×872."

reply :

Evaluation : The image itself is of good quality and presents a realistic image of Dora. However, the model failed to output at the specified size, which is an obvious flaw.

Final evaluation

Although the quality of the model output is acceptable, it is difficult to fully evaluate its capabilities based on these tests alone, because the core advantage of Perplexity Pro is the freedom to switch a variety of top-level models. Sonar performs well for simple queries; but its limitations appear once the task becomes complex (such as precise control of image size). The purpose of Perplexity provides a variety of mature models is to match the most suitable choice for different tasks.

Notes on using Perplexity Pro

• Response delays may occur during peak periods.

• Poor performance in generating infographics, often occurring in the overlapping text and blurred data expression.

• Sometimes "illusion" occurs, that is, ignore user questions and generate irrelevant content by yourself. As shown in the figure below:
