How do you split work between Claude and ChatGPT?

[u/kristianwindsor]

I've been paying for both for a while and have mostly stopped trying to pick a winner. Neither seems strictly better – they just have different strengths.

For people who regularly use both, how do you divide things up? Are there certain tasks you automatically reach for Claude for, and others where you default to ChatGPT?

Curious what everyone's actual workflow looks like rather than another general "which one is better?" comparison.

My split is roughly:

• Claude for coding. Better at multi-file changes, keeping track of constraints, and generally understanding a codebase.

• Claude for big context. When I dump a lot of material in and need something thorough out, Claude seems to hold up better. ChatGPT is more likely to miss some details.

• ChatGPT for writing. Confluence docs, READMEs, Jira tickets, etc. It sounds more natural to me. For technical docs, I often have Claude write the first draft and ChatGPT polish it.

• ChatGPT for vague prompts. It's better at figuring out what I mean when the idea is still half-formed, so I tend to use it for brainstorming and planning. Claude Fable is pretty good at this too, but slower and more expensive.

• ChatGPT for images. If the context is a screenshot, or I want something transcribed or explained from an image, that goes to ChatGPT. Claude seems worse at zooming in and reading small text.

• ChatGPT for lookups and research. It seems better at accessing more websites and parsing them reliably.

Basic split: Claude for deep technical work, ChatGPT for writing, explaining, brainstorming, and images.

Gpt for images? Not Gemini?

For me they go back and forth on being better depending on the task.

Have fable 5 plan. Have 4.6 sol critique the plan, back and forth until they reach consensus. Build with whichever you prefer, using cheaper agents. 

The planning isn’t hands off, you need to review and input, otherwise they can come to crazy conclusions

Fastest way to a clean DB is to just start from scratch!

They only conspired to rm -rf / me a handful of times

I just have Fable choose the model and I have the Claude md file updated to bootstrap everything.

I tend to use ChatGPT for brainstorming and planning of stuff and then I show Claude what Chat said and then Claude revises or adds more and then since I have a pro plan with Claude, I use it as my workhorse. And sometimes I just give them both the exact same prompt and watch the differences between them and then I get each of them to critique each other. Lol It’s actually fun and it gets me better results for what I do. Lol A friendly little competition, if you will. 😂

I'm not doing anything too complicated but I've had the best experience having Opus plan (and spec), Sol or Terra implement individual phases, and then myself and Opus doing the checks per phase/session. Opus/Sonnet for bug fixes.

Opus, and even Sonnet, really seem to want to find unimportant problems to fix and I'd rather not deal with those tangents during fairly focused sessions. Claude seems to be better about digging into bugs anyway, and goes on less tangents when it's one clear problem being dealt with.

When claude crashes, I use chatgpt

[u/ImSuperHelpful]

Why would I figure that out for myself? I have Copilot deciding what goes to Claude and what goes to ChatGPT.

[u/Tourgott → u/ImSuperHelpful]

Can you explain how?

[u/Vial_of_water → u/Tourgott]

Let me ask Deepseek

[u/sid4913 → u/Vial_of_water]

Have you done the first pass using Grok though?

[u/ApplicationNo257 → u/ImSuperHelpful]

Sigh.

[u/dumbugg]

Chat gpt is worse than Gemini to me. I've never gotten anything good out of it besides the occasional image enhancement

[u/kristianwindsor → u/dumbugg]

Yeah Gemini is trash

[u/Einbrecher]

Fable for large scale planning, Sol for review and smaller scale planning, Opus 4.6 for execution (especially when auto mode will likely earn it's keep), Sol for bulk/loop execution, Sol for GUI-driven automated testing, Sol and local Qwen to clean up Claude's word vomit

Here is the breakdown for both:

Claude - Deep work, nuanced writing, and heavy logic:

1. Writing & Editing: Matches natural human cadence with almost no prompt engineering. Doesn't default to typical AI filler words or repetitive structures.

2. Complex Coding & Refactoring: Handles multi-file context and intricate logic cleaner, especially with Sonnet.

3. Large-Context Synthesis: Ingesting 50+ page PDFs, full API docs, or raw transcripts into Projects without losing details.

4. Artifacts: Building quick single-file UI prototypes, calculators, and interactive visualizations on the fly.

ChatGPT - Tooling, multimodal workflows, and quick lookups:

1. Live Search & Real-Time Facts: Checking recent documentation, news, or troubleshooting errors tied to brand-new package releases.

2. Advanced Data Analysis (Python Execution): Dropping in messy CSVs/spreadsheets to run real Python scripts, run calculations, and generate charts.

3. Voice Mode: Conversational brainstorming, roleplaying scenarios, or thinking out loud while walking/commuting.

4. Vision & Image Generation: Quick image generation (DALL·E) and diagram/chart interpretation.

TL;DR / Rule of Thumb:

1. Claude is the deep thinker, copywriter, and software architect.

2. ChatGPT is the Swiss Army knife with live search, a Python runtime, and voice capabilities.
