Ask five people in your office which AI assistant they use and you'll probably get at least two different answers: ChatGPT, and increasingly, Claude. Both are subscription AI assistants you can sign up for directly, independent of any Microsoft, Google or Apple product bundle, and both have improved rapidly over the past year. But they come from different companies, with genuinely different products underneath the similar-looking chat box, and the differences are worth understanding before you pick one for your team.
This is a slightly different comparison to our Microsoft Copilot vs ChatGPT article. Copilot and ChatGPT are related because Microsoft licenses OpenAI's models. Claude and ChatGPT aren't related at all, they're built by two separate AI labs, Anthropic and OpenAI, competing directly with their own models, their own products and their own approach to how an AI assistant should behave.
What Is Claude?
Claude is the AI assistant built by Anthropic, available through the Claude.ai website and app, as well as through business and developer products. As of mid-2026, Anthropic's current model lineup includes Claude Opus 4.8 (the flagship model for most demanding business and reasoning work), Claude Sonnet 5 (Anthropic's balance of speed and intelligence, and the model most Claude subscribers interact with day to day), Claude Haiku 4.5 (the fastest, most cost-efficient option for simple or high-volume tasks), and Claude Fable 5, Anthropic's most capable model, aimed at the hardest long-horizon reasoning and coding work.
Claude's current-generation models (Opus 4.8, Sonnet 5 and Fable 5) support a context window of up to 1 million tokens, roughly 750,000 words, meaning the model can hold a very large amount of text, code or documents in a single conversation. In practice, how much of that window you can actually use inside the Claude.ai app itself varies by subscription plan, it's a genuine technical capability of the model, but the working limit you'll experience day-to-day depends on which tier you're on.
Beyond the chat interface, Claude's notable features include Projects (organising related conversations and reference files together), Artifacts (a side panel that renders documents, code or interactive previews live as Claude writes them, rather than burying everything in chat text), and Claude Code, a coding-focused agent that runs in the terminal or IDE and has built a strong reputation among developers for handling multi-step coding tasks, refactors and debugging. Anthropic has also built out computer-use and "Cowork"-style capabilities that let Claude operate more autonomously across tools and tasks, and supports the Model Context Protocol (MCP), an open standard for connecting Claude to external tools and data sources.
What Is ChatGPT?
ChatGPT is OpenAI's own AI assistant, and remains the most widely recognised name in consumer AI. As of July 2026, OpenAI's current model family is GPT-5.6, released in three tiers: Sol (the flagship, for the most demanding reasoning and coding work), Terra (a balanced everyday model) and Luna (a fast, low-cost model for simpler tasks). Like Claude's top-tier models, GPT-5.6 supports up to a 1 million-token context window at the API level, though the ChatGPT app itself applies its own working limits depending on your plan and whether you're using standard or "thinking" (extended reasoning) mode.
ChatGPT's feature set is broad: Projects and Canvas (its equivalent of a live document and code editor), Advanced Voice for real-time spoken conversation, persistent memory across chats, native image generation, web search, Deep Research for longer investigative tasks, custom GPTs that let you build purpose-built assistants for specific workflows, and an evolving agent capability (recently folded into what OpenAI calls ChatGPT Work) that can carry out multi-step tasks with less manual guidance. ChatGPT also has, by a wide margin, the largest consumer user base of any AI assistant, which means the broadest ecosystem of third-party integrations, tutorials and community familiarity.

Where Each Tends to Stand Out
Both companies ship improvements at a genuinely fast pace, so any snapshot comparison is a moving target. That said, some patterns have held up consistently through 2026:
Claude has built a strong reputation, particularly among developers and enterprises, for coding quality (Claude Code is widely used for real production work), reliable behaviour over long conversations and large documents, and a generally more cautious, safety-conscious approach to how the model responds. Anthropic has also leaned into enterprise-friendly features, longer effective working context, Projects for organised knowledge work, and MCP for connecting Claude securely to a business's own tools and data.
ChatGPT tends to lead on breadth: it was first to popularise most of the features now considered standard across the industry, has the largest ecosystem of custom GPTs and third-party integrations, includes native voice and image generation as core features rather than add-ons, and because OpenAI builds both model and product together, new capabilities typically appear in ChatGPT before anywhere else, including before they reach Microsoft Copilot.
Neither is simply "better" in every dimension, they've made different design choices, and which one suits your business often comes down to what your team actually does day to day: heavy coding and long documents lean toward Claude; broad day-to-day use with voice, image generation and the widest range of ready-made integrations leans toward ChatGPT.
Pricing Comparison
Claude offers a free tier with limited daily usage on Sonnet and Haiku models. Claude Pro is $20/month and adds a much higher usage allowance, priority access and Claude Code. Two higher Max tiers, roughly $100/month (5x Pro's usage) and $200/month (20x), suit heavy individual users. For businesses, Team plans start at roughly $20–25/seat/month with shared workspaces, admin controls and single sign-on, and Enterprise is custom-quoted for larger organisations with more complex governance needs.
ChatGPT mirrors this structure closely. There's a free tier, a budget Go plan at around $8/month, the standard Plus plan at $20/month, and Pro tiers at $100–$200/month for the highest usage limits and access to the flagship Sol model. Business pricing for teams sits at roughly $20–25/seat/month, and Enterprise is custom-quoted.
💡 The entry price point is nearly identical. Both Claude Pro and ChatGPT Plus sit at $20/month for an individual. The decision usually comes down to which model your team's specific work suits better, and which ecosystem of features (voice and image generation vs. coding and long-document handling) you'll actually use, not the sticker price.
Data Handling for Business
Both companies offer paid business tiers with contractual guarantees that customer conversations aren't used to train their underlying models, standard for any AI vendor serious about enterprise customers in 2026. Team and Enterprise plans from both Anthropic and OpenAI include admin controls, centralised billing and single sign-on. Neither Claude nor ChatGPT is natively "grounded" in your company's internal files and emails the way Microsoft 365 Copilot is by default, both rely on you uploading documents, connecting approved data sources (via Projects, custom GPTs, or MCP-based tool connections), or using their respective enterprise search/connector features to bring in company context. If your business needs an AI assistant that automatically reads your existing emails and files without manual setup, that's the specific advantage Copilot offers over either of these products, worth reading alongside this if Microsoft 365 is central to how your team works.
Which Should Your Business Choose?
- Choose Claude if your team does significant software development, works with long documents or codebases regularly, or values a model with a reputation for careful, consistent behaviour over long tasks.
- Choose ChatGPT if you want the broadest day-to-day feature set, including voice conversation and image generation, the largest library of ready-made custom GPTs, or your team is already comfortable in the ChatGPT ecosystem.
- Consider running both, plenty of businesses do. It's increasingly common for organisations to give developers a Claude seat for coding work while the rest of the business uses ChatGPT (or Copilot) for general tasks, rather than trying to force one tool to be everything for everyone.
Whatever you land on, the part that actually protects your business isn't the model you pick, it's having a clear policy for what staff can and can't paste into any AI tool, and making sure whichever platform you choose is licensed on a business tier with the right data-handling guarantees, not a personal account someone signed up for on their own card.
Frequently Asked Questions
- Is Claude better than ChatGPT for coding? Claude has a strong reputation among developers, largely through Claude Code, for handling complex, multi-step coding tasks reliably. OpenAI's GPT-5.6 Sol model was also specifically optimised for coding and agentic work, so both are genuinely strong options; many developers use both depending on the task.
- Which has a bigger context window? Both Claude's current top-tier models (Opus 4.8, Sonnet 5, Fable 5) and OpenAI's GPT-5.6 Sol support up to roughly 1 million tokens at the model/API level. What you can actually use inside each company's own consumer chat app varies by subscription plan.
- Can I use Claude and ChatGPT together in my business? Yes, there's no technical or licensing conflict in running both, and many businesses do, matching each tool to the tasks it handles best.
- Which is cheaper? Entry-level pricing is nearly identical, Claude Pro and ChatGPT Plus both cost $20/month for an individual. Higher usage tiers on both sides scale up to $100–$200/month.
- Does either train on my company's data? Both Anthropic and OpenAI contractually guarantee no model training on conversations from their paid Team, Business and Enterprise tiers. Free and some individual paid tiers may have different defaults, always check the current terms for the specific plan you're on.
If your business is trying to decide between Claude, ChatGPT, Microsoft Copilot, or some combination of all three, and wants a clear-eyed, vendor-neutral recommendation based on how your team actually works (not just whichever tool is loudest in the news that week), that's exactly what our Data & AI Solutions team helps Melbourne businesses work through.
