This image was generated, based on my prompting, by ChatGPT.
As of February, 2025, when this is being written, several major artificial intelligence engines are publicly accessible through free tiers, temporary free access, or subscription-based models with broad availability.
I have been evaluating ChatGPT-4 (aka ChatGPT, OpenAI, introduced 11/2022) and very recently, Grok 3 (aka
Grok, xAI,
introduced 2/2025).
I requested from both ChatGPT and Grok, tables of comparison and contrast
between the two, based on "Aspect" criteria I provided. Those results are presented below. They seem to be
mostly honest
assessments. Interestingly though, ChatGPT, long accused of being politically
biased, pleads not guilty in its own opinion.
Grok begs to disagree, citing
ChatGPT's restricting of certain topics.
Perhaps not surprisingly, Grok 3 often invoked the name of its founder
(Mr. Musk) during my interactions with it on wireless communications topics. I
will reveal more on that later. Grok 3 definitely has a personality (or AIality©)
with a touch of wit and humor.
Underneath that on this page is a rundown of the most prominent AI engines currently available to the public, based on their visibility, usage, and accessibility trends. These engines dominate public access now - ChatGPT and Grok 3 lead conversationally, Gemini and Perplexity excel in search, Claude offers polish, DeepSeek surprises with value, and Llama caters to DIYers. Most are free at entry level, with paid tiers unlocking extras (e.g., ChatGPT's image creation, Grok's
planned voice mode). Availability shifts fast - Grok 3's free window might close soon
- so they're all fair game today.
These tables are exactly the format provided by the two AI engines. I
requested they be provided in HTML format that could be pasted directly into the
page.
| Maturity of Technology |
Launched in 2022 by OpenAI, ChatGPT has undergone several iterations, with the
latest being GPT-4o. |
Introduced by xAI in February 2025, Grok 3 is a relatively new entrant in the
AI chatbot landscape. |
| Growth Rate of Data and Reasoning Capability |
ChatGPT has seen continuous improvements in data processing and reasoning, with
a 33% increase in weekly active users since December 2024, reaching 400 million. |
Grok 3 was trained using ten times more computing power than its predecessor,
Grok 2, utilizing approximately 200,000 GPUs. It emphasizes advanced reasoning capabilities,
with modes like "Think" and "Big Brain" for complex problem-solving. |
| Currency of Available Information |
ChatGPT's responses are based on its training data up to its last update, with
limited real-time information access. |
Grok 3 integrates with X (formerly Twitter), providing real-time data access
and up-to-date responses. |
| Planned Capability Expansion |
OpenAI plans to introduce voice interaction and desktop applications, along
with an AI gaming studio. |
Grok 3 is expected to introduce a multimodal voice mode and plans to open-source
Grok 2 in the coming months. |
| Image Ability (Creation and Interpretation) |
ChatGPT primarily focuses on text-based responses with limited image generation
capabilities. |
Grok 3 offers image generation features, utilizing FLUX.1 from Black Forest
Labs. |
| Amount of Content in Response to Query |
ChatGPT provides detailed and contextually rich responses, with the ability
to generate extensive content. |
Grok 3 offers concise answers with options for more detailed reasoning through
"Think" and "Big Brain" modes. |
| Degree of Political Correctness |
ChatGPT maintains a neutral tone, adhering to strict content guidelines to avoid
controversial topics. |
Grok 3 is designed with a "rebellious streak," willing to address "spicy" questions
often avoided by other AI systems. |
| Data Sources and Acquisition |
ChatGPT is trained on a diverse range of internet text up to its last update,
without real-time data integration. |
Grok 3 leverages real-time data from X, providing current information and trends. |
| Ability to Follow User Instructions |
ChatGPT excels in understanding and following user instructions, offering versatile
and context-aware completions. |
Grok 3 emphasizes advanced reasoning and problem-solving, with modes tailored
for complex tasks. |
|
| Maturity of Technology |
Highly mature - launched in November 2022, built on GPT architecture (GPT-4/4o
by 2025). Over 2 years of refinement, widespread adoption (100M+ weekly users). |
Emerging - launched February 20, 2025, as Grok 3. Less than a week old, built
on custom xAI tech, rapidly evolving from Grok 1 (2023). |
| Current Growth Rate of Data & Reasoning |
Steady - GPT-4's growth slowed post-2023, but reasoning improved (e.g., 40% more
accurate vs. GPT-3.5). Data expansion via plugins/Bing integration, not raw corpus
size. |
Explosive - 10x compute jump from Grok 2 (200,000 GPUs), reasoning up 50%+ (e.g.,
59% to 93% on math benchmarks in 18 months). Real-time X data fuels rapid knowledge
gains. |
| How Current Available Information Is |
GPT-4: Static to April 2023, augmented by Bing search in Plus tier. Lags without
real-time feeds unless prompted with current info. |
Real-time via X platform integration - accesses posts up to February 23, 2025.
Excels at current events, though depth varies beyond X. |
| Planned Capability Expansion |
"Operator" AI agent (2025 beta) for web tasks, Canvas collaboration interface, Sora video generator
- focus on multi-modal and ecosystem integration (e.g., Apple
Intelligence). |
Voice Mode (March 2025), "DeepSearch" for research, Aurora image refinement
- aims
for reasoning depth ("Think" mode) and broader X ecosystem tools. |
| Image Ability (Creation & Interpretation) |
Creation: DALL·E 3 in Plus tier - solid, photorealistic, but spelling errors and
no edits. Interpretation: GPT-4V processes images/documents well. |
Creation: Aurora engine - photorealistic, beats DALL·E 3 in detail, editable post-creation,
less censored. Interpretation: Limited to text for now, no visual input yet. |
| Amount of Content in Response |
Verbose - detailed, often 200-500 words, adjusts to query complexity. Strong context
memory aids follow-ups. |
Concise but thorough - 100-300 words typical, "Think" mode adds step-by-step reasoning.
Less chat history retention so far. |
| Degree of Political Correctness |
High - 82% less likely to answer restricted queries (e.g., ethics judgments),
leans cautious and polished after RLHF tuning. |
Low - "Rebellious streak," avoids ethical calls (e.g., no "who deserves to die"),
less filtered, Musk's "anti-woke" ethos shines. |
| Where & How Data Is Obtained |
Static corpus (web texts, books) to 2023, plus Bing for Plus users. Trained
on diverse, public internet data, refined with human feedback. |
Real-time X posts (public data stream), web scrapes pre-2025, custom stack (Kubernetes,
Rust, JAX). X focus gives current, social slant. |
| Ability to Follow User Instructions |
Excellent - context-aware, adjusts tone/style, strong at multi-step tasks (e.g.,
coding, writing) with clear prompts. |
Very good - "Think" mode shows logic, follows well but less polished. Early bugs
(e.g., image prompt misreads) suggest room to grow. |

- ChatGPT (OpenAI)
Accessibility: Free tier (GPT-3.5) via chat.openai.com; GPT-4o and ChatGPT Search available with a $20/month Plus subscription.
Details: Launched in November 2022, ChatGPT remains a benchmark with its conversational prowess. The free version uses older data (pre-2023), while paid tiers offer real-time search and advanced reasoning (e.g., o1-preview). Widely used for text generation, coding, and more, it's accessible globally with an internet connection.
- Grok 3 (xAI)
Accessibility: Free to all users as of February 20, 2025, via xAI's platform (likely xAI.com or X integration), though this is a limited-time offer until server capacity is tested. Paid tiers (e.g., X Premium, $8/month) provide higher limits.
Details: Released just days ago, Grok 3 boasts real-time X data integration and strong reasoning (e.g., 59% on tough math benchmarks). It's pitched as less censored, appealing to hobbyists for unfiltered tech chats—perfect for RF Cafe or AirplanesAndRockets.com brainstorming.
- Gemini (Google)
Accessibility: Free via gemini.google.com; advanced features (e.g., Gemini 1.5 Ultra) tied to Google One AI Premium ($20/month).
Details: Launched in 2023, Gemini powers Google's AI ecosystem, including search overviews. It's real-time via Google's web crawl, excelling at quick answers and image interpretation—handy for model aviation visuals—but lacks Grok's raw edge.
- Claude (Anthropic)
Accessibility: Free tier (Claude 3 Sonnet) at claude.ai; premium Claude 3.5 Opus via $20/month subscription.
Details: Debuted in 2023, Claude shines in safety and clarity, competing with GPT-4 on reasoning tasks. Its free version is robust for writing (e.g., your tech articles), though data is static (pre-2024) without paid real-time access. Less quirky than Grok.
- Perplexity AI
Accessibility: Free at perplexity.ai; Pro version ($20/month) unlocks advanced models and higher query limits.
Details: A 2023 entrant, Perplexity blends search and AI, citing sources in real-time web responses. It's a favorite for research—imagine digging into 1920s model plane history—though its conversational depth trails ChatGPT and Grok.
- DeepSeek-R1 (DeepSeek)
Accessibility: Free via deepseek.com or app stores; no clear paid tier yet.
Details: Launched in early 2025, this Chinese AI stunned with GPT-4-level logic at low cost, topping Apple's App Store briefly. It's fresh (real-time data unclear), lean, and accessible—great for quick RF queries, but less proven than veterans.
- Llama (Meta AI)
Accessibility: Free via research access or third-party platforms (e.g., Hugging Face); Llama 3.3 public via meta.ai in 2025.
Details: Open weights since 2021, Llama's latest (2024–2025) offers GPT-3-like power. Hobbyists tweak it locally, but public web access is newer—less chatty, more DIY, fitting your tech tinkerer vibe.
