AI Model Comparison

The underlying models define what each platform can actually do. Here is how the latest flagships stack up in early 2026.

GPT-5.2 (OpenAI)

Released December 2025, GPT-5.2 leads in abstract reasoning and mathematical problem-solving. It scored a perfect 100% on AIME 2025 (a competitive math benchmark) without tools and hit 54.2% on ARC-AGI-2, a test designed to measure genuine reasoning ability. The model supports up to 400K tokens of context — roughly 300,000 words or 800 pages.

GPT-5.2 also produces the cleanest code in terms of error rates. Testing by SonarSource found just 22 control flow mistakes per million lines of code, the lowest among all frontier models.

Claude Opus 4.5 (Anthropic)

Released November 2025, Opus 4.5 is the first model to exceed 80% on SWE-bench Verified (80.9%), solving 405 out of 500 real-world GitHub issues autonomously. It leads on coding benchmarks overall and produces the most natural-sounding prose among the three.

Opus 4.5 offers a 200K token standard context window that scales to 1M tokens, with a 128K output token limit for comprehensive responses. Where it particularly excels is maintaining reasoning quality throughout long documents — independent testing shows it produces fewer hallucinations and maintains higher attention to detail when processing documents exceeding 50,000 tokens.

Gemini 3 Pro (Google)

Released November 2025, Gemini 3 Pro holds the largest standard context window at 1 million tokens and broke the 1,500 Elo barrier on LMArena — a first in AI history. It achieved gold-medal performance at the International Mathematical Olympiad and scored highest on Humanity’s Last Exam at 41.0%.

Gemini 3 Pro is noticeably faster in response times than both competitors and offers the most cost-effective API pricing — up to 20-40x cheaper than Claude for high-volume applications.

Benchmark Summary

Benchmark	GPT-5.2	Claude Opus 4.5	Gemini 3 Pro
ARC-AGI-2 (reasoning)	54.2%	37.6%	45.1%
AIME 2025 (math)	100%	—	100% (w/ tools)

No single model dominates across every benchmark. GPT-5.2 leads in reasoning, Claude Opus 4.5 leads in coding, and Gemini 3 Pro leads in long-context tasks and raw scale.

Writing Quality Comparison

For content creators, writers, and marketers, writing quality is often the deciding factor. Here is how each platform handles different writing tasks based on extensive testing.

ChatGPT — The Creative Generalist

ChatGPT adapts well to different tones and formats. It handles creative writing, social media copy, blog posts, and instructional content with consistent quality. GPT-5.2 generates polished output that works well for marketing and general-purpose content.

Strengths: Creative flexibility, good at matching requested tones, strong instructional and explainer content, solid social media copy

Weaknesses: Can sound overly enthusiastic or formulaic in long-form content. Tends toward certain repetitive patterns (“it’s important to note,” “at the end of the day”) that require editing.

Claude — The Nuanced Writer

Claude consistently produces the most natural, human-sounding text among the three. It excels at matching writing style and tone with less prompting, and its output requires less editing to sound authentic. For long-form articles, reports, and content that needs to read like it was written by a skilled human, Claude has a measurable advantage.

Strengths: Most human-like prose quality, excellent tone matching, strong long-form coherence, fewer AI-sounding patterns, best for think pieces and analysis

Weaknesses: Can be overly cautious or hedging in its language. Sometimes produces more qualified statements than necessary.

Gemini — The Research-Backed Writer

Gemini produces clear, structured, fact-forward writing. Its deep integration with Google Search means it can pull in current data and citations naturally. For educational content, research summaries, and factual writing, Gemini delivers well-organized output.

Strengths: Strongest factual accuracy through Google Search integration, well-structured explanatory content, good for data-heavy writing

Weaknesses: Tone can feel neutral and lacks personality. Not as strong at maintaining a consistent voice across long pieces. Creative writing feels more formulaic compared to ChatGPT and Claude.

Writing Verdict
