ChatGPT Pricing

Plan	Monthly Cost	What You Get
Free	$0	GPT-4o mini, file/image uploads, basic browsing, GPT Store
Plus	$20/mo	GPT-4o, GPT-5 access, DALL-E image generation, advanced voice, custom GPTs
Pro	$200/mo	Unlimited o1 access, o1 pro mode, 250 deep research runs/month
Team	$25-30/seat/mo	Shared workspaces, higher limits, admin tools
Enterprise	Custom	Unlimited GPT-5, SSO, SOC 2 compliance, analytics dashboards

At the $20/month tier, both are identical in price. The real difference shows up at the power-user level: Claude Max starts at $100/month for 5x usage, while ChatGPT Pro jumps straight to $200/month. If you need more than the standard Pro limits but do not need unlimited o1 reasoning, Claude Max at $100 offers a middle ground that ChatGPT lacks.

Coding Ability

This is where the rivalry gets serious. Both tools are used daily by professional developers, and benchmarks show meaningful differences.

Benchmark Performance

Claude Opus 4.5 scored 80.9% on SWE-bench Verified, a benchmark that tests real-world software engineering tasks. GPT-5.2 landed around 70% on the same benchmark. In functional accuracy tests across multiple programming languages, Claude consistently hits approximately 95% versus ChatGPT’s 85%.

These numbers translate into real differences when you are debugging complex issues or refactoring large codebases. Claude tends to produce cleaner, more idiomatic code with better variable naming and structure right out of the gate.

Where ChatGPT Wins at Code

ChatGPT is faster at generating quick code snippets and handles a wider variety of programming languages thanks to its enormous training data. If you need a fast solution and plan to clean it up yourself, ChatGPT gets you there quicker. It also integrates tightly with GitHub Copilot, which matters if your workflow already depends on that tool.

Where Claude Wins at Code

Claude’s strength is in understanding and analyzing existing code. Its 200K native context window (with 1M tokens in beta through the API) means you can feed it entire codebases and get coherent analysis back. When you need to understand why a bug exists rather than just patch it, Claude’s reasoning approach pays off. Claude Code, available with the Pro plan, operates directly in your terminal and can handle multi-file refactoring tasks autonomously.

Practical Takeaway

For quick fixes and broad language support, ChatGPT is efficient. For deep debugging, architecture decisions, and working with large codebases, Claude delivers more reliable results.

Writing Quality

Both tools can produce competent prose, but they approach writing differently.

Claude’s Writing Style

Claude tends to produce writing that reads more naturally. It avoids the predictable sentence structures and filler phrases that plague many AI-generated texts. When given a complex topic, Claude will sometimes push back on your approach or suggest alternatives — behavior that can feel annoying when you just want output, but valuable when you want genuine quality.

For long-form content like reports, documentation, or articles, Claude’s larger context window means it maintains coherence across thousands of words without forgetting what it said earlier. The writing stays consistent in tone and argument throughout.

ChatGPT’s Writing Style

ChatGPT follows instructions more literally. If you give it a detailed brief, it will execute that brief faithfully without much pushback. This makes it excellent for structured content like email templates, social media posts, and marketing copy where you know exactly what you want.

ChatGPT also has a persistent memory feature that remembers your preferences across conversations. Over time, it adapts to your writing style without needing to be reminded of your preferences in every session.

Practical Takeaway

Choose Claude when tone, nuance, and long-form coherence matter. Choose ChatGPT when you need fast, instruction-following output and want the AI to remember your preferences over time.

Context Window

Context window size determines how much information the AI can process at once — critical for analyzing long documents, codebases, or maintaining extended conversations.

Feature	Claude	ChatGPT
Standard context	200K tokens	128K tokens (GPT-4o)
Extended context	1M tokens (beta, API)	200K tokens (select models)
Max output tokens	128K (Opus 4.6)	~16K (GPT-4o)
Conversation compaction	Yes (infinite conversations)	Limited

Claude holds a significant advantage here. Its 200K token standard context is larger than ChatGPT’s default, and the 1M token beta pushes it even further for users who need to process book-length documents or massive codebases. The 128K max output token limit on Opus 4.6 also means Claude can generate much longer responses in a single turn — useful for generating complete documents or large blocks of code.

Reasoning and Problem-Solving

Claude’s Approach

Claude Opus 4.6 introduced adaptive thinking, which automatically adjusts the depth of reasoning based on problem complexity. For simple questions, it responds quickly. For hard problems, it engages extended thinking that works through the problem step by step before answering. This adaptive approach means you get speed when you need it and depth when the problem demands it.

ChatGPT’s Approach

OpenAI’s o1 and o1 pro models were specifically designed for deep reasoning. Available on the $200/month Pro plan, o1 pro uses extra compute to work through difficult math, science, and logic problems. For researchers and engineers tackling genuinely hard problems, this dedicated reasoning model is powerful.

ChatGPT also offers Deep Research, which can autonomously browse the web, analyze files, and compile cited research reports — something Claude does not match in its current form.

Practical Takeaway

For everyday reasoning tasks, Claude’s adaptive thinking works well without requiring you to switch models. For research-grade problems in math and science, ChatGPT Pro’s o1 models are purpose-built and worth the premium.

API Pricing

For developers building applications, API costs matter enormously at scale.

Claude API Pricing (per million tokens)

Model	Input	Output
Haiku 4.5	$1	$5
Sonnet 4.5	$3	$15
