The comparison that we share here also covers how these models are deployed, where they are available, what kind of subscriptions they offer, how long their context windows are, how fast they respond, and... It also includes support for images, file uploads, voice, and multi-language interactions, as well as differences in app integration, privacy policies, transparency of model capabilities, and enterprise features. OpenAI (ChatGPT): As of mid-2025, OpenAI’s flagship model is GPT-4.5, an enhanced version of GPT-4 (sometimes referenced as GPT-4.1 for a code-optimized variant). GPT-4.5 was introduced in April 2025 for ChatGPT Pro users and later rolled out to Plus users. The original GPT-4 (now termed GPT-4o) remains available, and OpenAI also offers specialized models like GPT-4.1 (tuned for coding tasks) and a fast GPT-4.1 “mini” model. All these models power ChatGPT’s various modes (e.g.

default, Code Interpreter, etc.), with GPT-4.5 being the most capable general model. OpenAI has not disclosed the parameter counts or full training data details for these models (citing competitive and safety reasons), but GPT-4.5 was trained with new techniques and larger-scale data built upon GPT-4. GPT-4.5 is natively multimodal to an extent – it supports image inputs and file uploads, and integrates search capabilities – though it does not yet directly produce images or audio in ChatGPT. Its knowledge cutoff has been extended via retrieval (live web search integration) to provide up-to-date information (GPT-4o’s pre-training cutoff was 2021). In practice, GPT-4.5 is described as having higher “EQ” (emotional intelligence), creativity, and steerability than GPT-4o, at the cost of being extremely compute-intensive (hence offered initially only to higher-tier subscribers). Anthropic (Claude): Anthropic’s latest generation is Claude 4, released in May 2025.

Claude 4 comes in two main variants: Claude 4 Opus (the largest, highest-performing model) and Claude 4 Sonnet (a slightly smaller, faster model). These succeeded the Claude 3 series (Claude 3, 3.5, 3.7) which were introduced through 2024. Claude 4 Opus and Sonnet are both state-of-the-art in capability – in Anthropic’s internal evaluations, Claude 4 (especially Opus) outperforms the original GPT-4 and Google’s Gemini on many knowledge and reasoning benchmarks. For example, Claude 3 (2024) was already touted as “more skilled...and better at reasoning” than GPT-4 and Gemini’s model at the time, and Claude 4 has further improved. Claude 4 retains Anthropic’s signature 100k+ token context window (expanded to 200,000 tokens in Claude 3.5/4 for the default models, with up to 1 million tokens possible in special cases or enterprise settings) –... Claude 4 is also natively multimodal in input: it can accept uploads of various file types (PDF, images, documents, etc.) and will analyze or summarize their content.

However, Claude’s outputs are text-only; it does not generate images or audio. Anthropic has been relatively transparent about how Claude is trained (using their “Constitutional AI” technique for alignment – see Safety & Alignment below), but like OpenAI, they do not publish parameter counts or the... The Claude 4 models are available via a web interface (claude.ai) and API, with Claude 4 Sonnet notably available even to free users (making it “unusually accessible for a model of this quality”). The more powerful Claude 4 Opus is reserved for paid tiers. Google (Gemini): Google’s next-generation AI model family is Gemini, and by mid-2025 the latest release is Gemini 2.5. This succeeded the initial Gemini 1.0/1.5 (introduced late 2023) and Gemini 2.0 (early 2024) models.

The top model is Gemini 2.5 Pro, which Google describes as its “most powerful thinking model” with state-of-the-art performance in complex reasoning, coding, and multimodal understanding. Alongside Pro, Google offers Gemini 2.5 Flash and Flash-Lite variants – these are optimized for faster, cost-efficient inference with slightly lower capability. All Gemini 2.5 models are deeply multimodal: they can accept text, images, audio, and even video inputs natively, and primarily produce text outputs. (Certain specializations of Gemini can also output audio or images, such as text-to-speech and image generation models within the Gemini API.) Notably, Gemini’s architecture incorporates techniques from Google DeepMind’s AlphaGo—Demis Hassabis has noted that... Google has not released parameter counts or detailed training data info for Gemini, but has indicated it was trained on a vast multimodal dataset (text, images, code, etc.) and with significant computational expense (comparable... By mid-2025, Gemini 2.5’s knowledge cutoff extends into 2024 (the models have a knowledge cutoff of August 2024 for 2.x series), and Google has integrated it across many products.

“Gemini” also refers to Google’s consumer-facing AI assistant (formerly known as Bard) – Bard was rebranded to Gemini in early 2024, with Gemini Advanced as a premium tier chatbot using the most capable model... In summary, Google’s Gemini 2.5 Pro is a cutting-edge multimodal model on par with the latest from OpenAI/Anthropic, with particular strengths in multimodal tasks and integration with tools. All three models are top-tier in general knowledge and language understanding, routinely outperforming or matching human experts on academic benchmarks. OpenAI’s GPT-4 family has demonstrated extraordinary breadth of knowledge (its predecessor GPT-4 scored around 86% on the MMLU academic knowledge benchmark) and GPT-4.5 continues this trend. OpenAI reports GPT-4.5 to be slightly better than GPT-4o on factual and commonsense tasks, thanks to training on more data and with “scalable supervision” techniques. It also has improved multilingual capabilities (e.g.

~85% on a multilingual MMLU test). Claude 4 likewise has near human-level knowledge integration; Claude 3 was said to exhibit “near-human levels of comprehension and fluency on complex tasks”. Claude’s knowledge base was updated through early 2024, and Claude 4’s knowledge cutoff is around mid-2024. It excels at understanding long or complex inputs due to its massive context window (discussed below), which allows it to absorb entire documents or books of information for use in a conversation. Google’s Gemini 2.5 has the advantage of integrating live search and up-to-date information from the web. In fact, Gemini’s API offers an optional “Grounding with Google Search” feature where the model can automatically fetch and cite information from the web during queries.

This means Gemini can provide current real-time knowledge (at some cost in API usage), whereas ChatGPT and Claude rely on their training data or user-provided info unless explicitly connected to external tools. On standard knowledge tests, Gemini’s performance is comparable to GPT-4: early versions (Gemini 1.0 Ultra) were roughly on par with GPT-4’s scores, and by 2.5 Pro Google claims it leads certain leaderboards. For example, Gemini 2.5 Pro is noted to be top-ranked on LMArena, a community benchmark aggregating language tasks. All three can handle nuanced questions, multi-turn explanations, and open-ended Q&A with a high degree of fluency. In practice, ChatGPT (GPT-4.5) and Claude might have a slight edge in strict factual accuracy on long-tail queries, as early reviews of Gemini Advanced (1.0) noted it sometimes produced more factual errors or contradictions... However, Gemini’s integration with search and its “world model” approach (drawing on simulation and planning techniques) are intended to mitigate hallucinations and improve factual grounding over time.

All three systems still occasionally hallucinate (output false but confident-sounding statements), a common limitation of large language models, so each has ongoing efforts to reduce that.
