Use Claude chat when the main job is to discuss, analyze or create material in a conversation. Use Claude Code when the job is to change and verify a software project in its working environment. Both can help with code. The distinction is how they receive context, act on files and tools, and return work you can inspect.
First, separate the three meanings of Claude
Claude models are the underlying models, such as Sonnet. Claude chat is the general assistant experience on Claude's website and applications. Claude Code is Anthropic's coding product. Choosing Claude Code does not mean choosing a completely unrelated model, and buying API access does not mean buying every feature of the Claude application.
The Claude product overview describes the broader assistant. The Claude Code overview describes its development surfaces, including terminal, IDE, desktop and browser. Consequently, “browser versus terminal” is no longer a sufficient way to distinguish these products.
Claude vs Claude Code at a glance
| Decision | Claude chat | Claude Code |
|---|---|---|
| Typical starting point | A question, document, data file or conversation | A repository, issue or development task |
| Context | Messages, supplied files and enabled connections | Project files and tools available to its session |
| Execution | Documented computing and connected tools where enabled | File edits and development commands with configured permissions |
| Useful output | An explanation, analysis, draft or generated artifact | A reviewable project change with verification |
| Billing choice | Claude account and its plan options | Eligible plan or supported API/provider route |
When chat is enough
Start with chat when you want to understand an unfamiliar function, consider an architecture tradeoff or analyze an uploaded dataset. If the result is something you intend to read and decide on, a conversation can be the right workspace. Give the relevant context and state what decision the response should help you make.
Chat is not restricted to producing text. Anthropic documents code execution and file creation for tasks such as data analysis and document generation. Those tools operate in their configured environment. A script that runs there does not establish that your local application's tests pass or that your repository has received the proposed change.
When to move the task into Claude Code
Choose Claude Code when completing the request requires following references across files, editing the implementation and running the project's own checks. Its quickstart walks through opening a project and asking it to inspect and change code. You can provide an outcome and let it find relevant files instead of repeatedly copying snippets between the repository and chat.
Carry over a compact specification from the conversation: the problem, expected behavior, constraints and how to verify success. You usually do not need to paste an entire chat transcript. For example:
Problem: saving an empty profile name currently succeeds.
Expected behavior: show a validation error and keep the previous name.
Inspect the existing validation and tests first.
Propose the smallest change before editing.
After implementation, show the diff and the relevant test result.Choose the permission mode that fits the work before execution. Review the final diff and the actual check results. An agent's statement that a bug is fixed is less useful than a change you can inspect and a relevant test you can reproduce.
One account can cover both, but API billing is separate
An eligible Claude plan can provide both chat and Claude Code access. Anthropic's usage documentation explains the shared allowance across relevant Claude surfaces. Switching from a chat to Claude Code is therefore not a way to manufacture another pool of included usage.
Claude Code can also use a supported API route. Compare the active account and model, rather than assuming a successful login proves every request is part of your subscription. Its cost documentation explains how context and execution affect model consumption. A long repository task can require several calls and repeated tool results.
For Kunavo's Claude Code route, Claude Sonnet 4.6 currently costs $1.20 input and $6.00 output per million tokens. Follow the Claude Code API-key setup to configure the endpoint and credential together. This configures Claude Code; it does not replace the account or payment settings in the Claude chat website.
Choose a starting workflow
- Learning or planning: start in chat with a focused question and enough context to evaluate the answer.
- Working with uploaded documents or data: use the chat tools that produce the file or analysis you need.
- Implementing a repository change: open the project in Claude Code and define a bounded acceptance check.
- Separating coding spend from your plan: choose a supported API route and inspect the first task's recorded charges.
You can keep both workflows. Discuss the design where that is comfortable, then bring the actionable specification into the project. If you choose Kunavo for the coding session, create an account and check the result in usage after the first small task.
FAQ
What is the difference between Claude and Claude Code?
Claude can mean Anthropic's model family or its general assistant product. Claude Code is a development tool that can work with repository files, commands and coding workflows. This comparison uses Claude to mean the general chat experience; the same model family can power both products.
Can regular Claude write and execute code?
Yes. Claude chat can explain and generate code, and its documented computing environment can execute code and produce files. The distinction is the working environment: a chat's supplied content and computing tools are not automatically the same as Claude Code operating in your configured repository.
Do I need a separate subscription for Claude Code?
An eligible Claude subscription can provide Claude Code access. Claude Code also supports Console and other documented billing routes, with availability depending on the surface. An API balance is separate from a Claude subscription, so check which account is active before assuming a task is included.
Can I use a Kunavo key in the Claude chat website?
The Kunavo setup described here is for Claude Code's documented gateway configuration. It does not replace billing inside the Claude chat website. Use the Claude Code API-key guide to configure the supported client route and confirm the resulting usage in Kunavo.
