Artificial Intelligence's Newest Offering: GPT-5 - A Comparative Analysis of Its Capabilities Against the Market Rivals
In a groundbreaking announcement during a livestream, OpenAI has introduced GPT-5, a new AI system designed to redefine the boundaries of artificial intelligence.
GPT-5, the successor to GPT-4, boasts several enhancements and improvements, setting it apart as the leading AI model of 2025. It outperforms key competitors such as Anthropic's Claude Opus 4.1, Google’s Gemini 2.5 Pro, and Elon Musk’s xAI Grok 4 in several important benchmarks, particularly coding tasks.
The model's coding performance, as verified by the SWE-bench test, stands at 74.9%, making it the best performer in this domain. While GPT-5 leads in many key areas, xAI's Grok 4 Heavy model scored higher on the advanced multi-domain test Humanity’s Last Exam, indicating Grok has strengths in some complex reasoning tasks.
Google’s Gemini 2.5 Pro stands out with the largest context window (1 million tokens) and supports multiple input-output modalities, beneficial for multimodal applications. Claude Opus 4.1 offers strong performance balanced with robust privacy features suitable for regulated environments.
GPT-5's improvements are not limited to performance. The model now features a real-time router that adjusts its approach based on conversation type, complexity, tool needs, and user intent. This adaptation ensures a more personalised and efficient interaction.
One of the significant improvements in GPT-5 is the reduction in sycophantic replies. The tendency for such responses has been reduced from 14.5 percent to under 6 percent.
Pricing for GPT-5 is competitive. It costs $1.25 per million input tokens with a 90% cache discount and $10 per million output tokens. For those with more modest needs, GPT-5 Nano is priced at $0.05 and $0.40, respectively, for input and output per million tokens.
The integration of GPT-5 into ChatGPT as a single model eliminates the need for a separate reasoning model. The interface now includes customizable chat colours, and for Pro users, integration with Gmail, Google Calendar, and Google Contacts is available.
Users can now choose from four new personalities in settings: Cynic, Robot, Listener, and Nerd. GPT-5 can handle text, images, and voice in the same chat, and the "thinking" mode produces fewer hallucinations than GPT-4o or the o3 reasoning model.
In OpenAI's medical benchmark, GPT-5's hallucination rate is more than seven times lower than GPT-4o's. The rollout begins immediately for all user tiers, with enterprise and education customers gaining access next week.
With its balance of speed, cost, and depth of reasoning, GPT-5 offers a compelling choice for those seeking a versatile and efficient AI companion. The choice among GPT-5, Claude, Gemini, and Grok often depends on the user's priority between raw accuracy, context window size, modality support, or data privacy.
The new AI model, GPT-5, outperforms competitors in coding tasks with a SWE-bench test score of 74.9%, setting it apart as the leading AI model for 2025 in this domain. Additionally, GPT-5 features a real-time router that adjusts its approach based on conversation type, ensuring a more personalized and efficient interaction.
