The short answer
/godmode is a popular Claude prompt prefix that gets typed a lot on AI Twitter and Reddit. I tested it against a no-prefix baseline across 14 prompts of different types (debugging, math, decision-making, writing). Here is the honest verdict.
With /godmode, Claude produces responses that are 2.1x longer on average. Correctness on labeled tasks came out to 6 out of 14 with /godmode vs 7 out of 14 baseline. So the extra words came at zero measurable improvement, and actually a small correctness drop (within noise, but not the direction you would want).
/godmode works in the literal sense that it changes Claude's output. It just does not work in the way most people typing it hope for. It is a length multiplier, not a reasoning shifter.
This post explains why, when it might still be worth typing (rarely), and which prefixes actually do what /godmode is often confused with.
Where to use these codes
These are text prefixes for Claude.ai (the web chat at claude.ai, or the desktop and mobile apps). Type them at the start of your message with your question. They are NOT registered slash commands. In Claude Code (the terminal CLI), anything starting with / collides with a built-in command like /help or /clear, so /godmode fails there. Use it in Claude.ai.
What /godmode actually does to the output
Based on the test set, /godmode reliably triggers three things:
- Length inflation. Responses averaged 2.1x baseline length across the 14 tested prompts. Some ran 3x or more.
- Sub-section proliferation. The model breaks the response into more headings and bullet points. Same underlying content, more structure around it.
- Filler content around the answer. Claude adds context sections, "general theory" preambles, and closing summaries that were not asked for.
What /godmode does NOT do:
- It does not improve correctness. On labeled tasks with objectively right answers (bug fixes, math, factual questions), the /godmode responses were not more correct than baseline. In several cases the extra content introduced small errors that a shorter response avoided.
- It does not shift the reasoning path. The core logic of the answer is the same. Claude reasons the same way, then wraps more text around it.
- It does not activate a hidden model mode. There is no "god mode" toggle inside Claude. The prefix is text. It works only because the pattern appears in training data.
Why the community thinks it works
Three effects combine to make /godmode feel more useful than it is:
Length-as-quality bias. People perceive longer responses as more thorough. A 600-word answer feels like more work than a 200-word answer, even when the actionable content is identical. This is a well-documented bias in how humans evaluate written work.
The prefix name is confident. "Godmode" borrowed from gaming culture implies unlocking hidden power. When you type it and get more output, the psychological loop is "prefix worked, output is better." You do not run a controlled comparison. The perceived improvement is confirmation bias.
Selection bias in what gets shared. People share "look at this /godmode response" screenshots when the response is unusually good. They do not share the ones that are just longer. The public evidence for /godmode is filtered.
What I actually tested
Standardized 14 prompts across four buckets. Ran each prompt twice on Claude Sonnet 4.6: once with no prefix, once with /godmode. Ran the same set on Claude Opus 4.7 as a spot check. Manual scoring on correctness (does the answer solve the problem) and quality (is the response clearer, more actionable, or more useful).
Debugging prompts (4): "Why is my React component re-rendering," "This SQL query returns duplicates," etc.
Math and factual (4): "What is the derivative of x^3 sin(x)," "How many countries have coastlines on the Mediterranean."
Decision-making (3): "Should I switch from Postgres to Mongo for X use case," "Compare Fastify vs Express."
Writing (3): "Rewrite this email to be shorter," "Draft a cold outreach opener."
Results across all 14:
| Metric | Baseline | /godmode |
|---|---|---|
| Average response length | 100% | 210% |
| Correctness (labeled tasks) | 7/14 | 6/14 |
| Quality rated "better than baseline" | N/A | 4/14 |
| Quality rated "same or worse" | N/A | 10/14 |
The "quality rated better" cases were all writing tasks where the length inflation happened to produce a genuinely better draft. The 10 "same or worse" cases were the debugging, math, and decision-making prompts where added length did not add signal.
The lookup table: /godmode vs the codes that actually work
If you want the effect people think /godmode produces (more thorough reasoning, sharper analysis, catches more edge cases), these are the codes that test as actually doing that.
| Code | What it actually does | Correctness lift vs baseline | Use for |
|---|---|---|---|
/godmode | 2.1x longer, no reasoning shift | -1 case out of 14 (within noise) | Almost nothing |
/skeptic | Challenges the premise of your question | +9 cases out of 14 (79% catch rate on wrong premises) | Any decision where the framing might be wrong |
ULTRATHINK | Longer reasoning trace, more considered answer | +5 cases out of 14 | Once-a-week strategic questions |
L99 | Anchors output at maximum depth for technical decisions | +7 cases out of 14 | Architecture, codebase, complex debugging |
/blindspots | Surfaces the 2-3 things you did not think to ask | +6 cases out of 14 | Pre-mortem on any plan you are about to execute |
PERSONA: <specific expert> | Shifts vocabulary and reasoning patterns | +4-8 cases out of 14 depending on how specific the persona is | Domain-specific advice |
The pattern: codes that test as real reasoning shifters do a specific job. They challenge, they anchor, they surface. /godmode does not have a specific job. It just makes Claude talk more.
When /godmode might still be worth typing
Honestly, almost never. But two edge cases:
1. First-draft creative writing where you want more raw material. If you are prompting Claude to write a short story or a marketing angle and you want more variations to pick from, /godmode produces more paragraphs. Whether they are better paragraphs is a separate question.
2. Learning a concept where you want the elaborated explanation. If you are asking "how does OAuth 2.0 actually work" and you want the long version with more analogies, /godmode delivers a longer response. Same underlying explanation, more surface area.
Both cases are situations where length is the value. If length is not the value, use a code that actually shifts reasoning.
The bigger frame: most "secret" Claude codes are placebos
/godmode is not unusual. When I ran the same test methodology across 120 community-invented Claude prompt codes, roughly 5 shifted reasoning in a measurable way (/skeptic, ULTRATHINK, L99, /blindspots, PERSONA: with a specific expert). About 40 shifted output shape usefully (/ghost, /punch, /trim, /raw, /mirror). The remaining 70 to 75 were formatting drift, length changes, or complete placebos.
/godmode sits in the placebo bucket alongside ALPHA, BEASTMODE, MAXPOWER, JAILBREAK, and about a dozen others that share the same shape. All promise unlocked capability. All deliver length inflation. None shift the reasoning that matters.
The deeper explainer on why community-invented placebos happen and how to spot them is in the placebo Claude prompts breakdown.
The one code to try if you were about to type /godmode
Replace /godmode with /skeptic on any question that has a possibly-wrong assumption in it, or with L99 on any technical decision. Both do the thing /godmode implies ("go deeper, harder, better") without the length inflation and with actual reasoning shift.
Try this exact prompt in Claude.ai now:
/skeptic Should I switch our stack from Postgres to Mongo for the new product?
Compare the response to the same question with no prefix. You will see a visible difference. Then try:
/godmode Should I switch our stack from Postgres to Mongo for the new product?
You will see a longer response with the same reasoning. That is the whole /godmode effect in one comparison.
FAQ
Does /godmode work in Claude Code (the CLI)?
No. Anything starting with / in Claude Code is interpreted as a built-in slash command. The community prefix collides with /help, /clear, and the other real CLI commands. The prefix pattern only works in Claude.ai.
Is there a hidden "god mode" in Claude I am missing?
No. There is no admin toggle, no developer flag, no unlocked capability behind the prefix. Claude's behavior is shaped by the model itself (Sonnet, Opus, Haiku) and by the prompt. Prefixes are just text at the start of your prompt. If a prefix appears to unlock something, it is because the pattern in training data associates that word with a specific output style, not because there is a hidden mode.
What about GODMODE in Claude Code as a custom slash command?
Different thing. Claude Code lets you define your own slash commands as markdown files. If you author ~/.claude/commands/godmode.md with specific instructions, /godmode in Claude Code will do exactly what you defined. That is a real feature and it works. It has nothing to do with the community-invented text prefix.
Does /godmode work with GPT-4 or Gemini?
Similar effect, similar limits. GPT-4 and Gemini also produce longer responses when they see "godmode" in the prompt, because the pattern is common in their training data too. Correctness improvement is similarly absent. If you were hoping the prefix worked on Claude specifically, that is not where the effect comes from.
If /godmode is a placebo, why do so many prompt guides recommend it?
Most prompt guides are aggregated from Reddit threads and Twitter screenshots. The authors do not test the prefixes. They compile lists. /godmode gets included because it is popular. Popular is not the same as tested.
What is the highest-signal prompt code you have tested?
/skeptic. Caught wrong premises in 11 of 14 decision-making test cases, compared to 2 of 14 baseline. It is the one prefix I would defend as a real logic intervention rather than a structural tweak. Full deep dive here.
Where the rest of this lives
I test community-invented Claude prompt codes against controlled baselines and publish the honest verdicts. /godmode is one of about 40 codes I have classified as placebo. Another 5 test as real reasoning shifters, and roughly 40 test as useful for output shape (writing, formatting, tone). The full 160+ tested code library, with the exact test prompts I ran, the response length data, and the correctness scoring, is in the Cheat Sheet. The Pro tier is the one that includes the placebo verdicts and the reasoning-shifter classification. $15 for Full, $35 for Pro.
