🔬 DailySkill Everyday AI Test · 3-Model Blind Comparison

ChatGPT vs Claude vs Gemini:
20 Everyday Tasks, Blind-Judged

We gave ChatGPT, Claude and Gemini the same 20 everyday prompts on August 28, 2026. Their 60 answers were anonymized as A, B and C and scored by an AI judge (claude-sonnet-5) on a 5-criterion, 25-point rubric. Because the judge is itself a Claude model, some bias toward Claude-style answers is possible. Grok 4.6 was tested separately on September 11–12, 2026, was not blind-judged and is not ranked. No sponsors, no affiliate links.

Tasks Evaluated: 20 Real Missions
Blind-Judged Answers: 60 (3 models × 20)
Scores: 300 (60 × 5 criteria)
Models: ChatGPT (gpt-5.6-sol), Claude (Claude Code, model version not recorded), Gemini (gemini-3.1-pro-high)
Judging: Blind A/B/C, AI judge (claude-sonnet-5)
Run & judged: Aug 28, 2026 · plans not recorded
Correction (October 17, 2026). An earlier version of this page described a four-model “double-blind” benchmark with 80 blind outputs and ranked Grok first (24.35/25). That was wrong. Only ChatGPT, Claude and Gemini were blind-judged, on August 28, 2026, by an AI judge (claude-sonnet-5), not by people. Grok 4.6 was run separately on September 11–12, 2026; its scores were entered in our script without a blind step or a written rationale, and on some tasks only Grok used web search. We have removed Grok from the rankings, corrected the model names (the page previously listed GPT-4o, Claude 3.5 Sonnet and Gemini 2.0 Flash, which were not the models tested) and fixed several counts. A full four-model blind re-test, run on the same day with current versions, is planned. See every change.

Grok 4.6 — measured separately (Sep 11–12, 2026), not blind-judged

We ran the same 20 prompts through Grok 4.6 (grok CLI) two weeks after the blind judging. Those answers never went through the blind A/B/C step. The Grok scores this page used to show were entered in our script with no judge and no written rationale, and on some tasks only Grok used web search. The numbers are not comparable, so we removed them from the scoreboard, the matrix and the winner labels.

  • One thing we can check without a score: on the tweet task (Day 26), Grok's answer was 304 characters, over the 280-character limit.
  • Grok was not blind-judged; its raw answers are included in the CSV/JSON downloads without scores, so you can read them yourself.
  • Grok will be included in the planned same-day, four-model blind re-test.

High-Impact Verification

The Hall of AI Blunders

Real mistakes detected during empirical testing. These aren’t edge cases; they are genuine failures where frontier AI models ignored safety limits, breached explicit formatting caps, or hallucinated details.

Read the full blunder write-up →

🚨 Safety Hazard Day 13 · Workout Plan

Gemini Prescribes Dumbbell Thrusters to Lower Back Patient

User Constraint: “Mild lower back issue, avoid heavy spinal loading.”

While Claude (25/25) chose spine-friendly, supported movements, Gemini (21/25, Accuracy 3/5) placed fast-paced 45-second intervals of “Dumbbell Thrusters” (explosive deep squat to overhead press) into a Friday circuit. For someone with spinal vulnerabilities, rapid under-load compression poses an acute injury hazard.

Key Lesson: Never rely on AI for injury rehabilitation without explicitly checking exercise biomechanics.
🍳 Constraint Breach Day 14 · Recipe Builder

Claude Hallucinates Oil & Seasonings in Strict Leftover Prompt

User Constraint: “Give me 3 different recipes I can make using only these ingredients.”

Claude (21/25, Completion 3/5) directly violated negative boundaries by injecting “a little oil” and “season with salt/black pepper” into Recipe 2. In contrast, ChatGPT (25/25) opened with: “No oil or seasonings are required” and ingeniously instructed using tomato water to sauté instead of oil.

Key Lesson: Models default to standard recipe training distributions unless negative constraints are strictly reinforced.
📏 Hard Limit Failure Day 26 · Tweet Summary

Claude Blew the 280-Character Cap (289 Characters)

User Constraint: “Summarize this article into one tweet of 280 characters or fewer.”

Claude produced 289 characters on an explicit 280-character tweet task. That would not fit in a standard post on X. Gemini won (25/25) with a 275-character hook that ended on a curiosity gap; ChatGPT also stayed under the limit (251 characters).

Key Lesson: LLMs predict tokens, not characters; always programmatically verify character limits on social copy.
📅 Chronological Inversion Day 27 · Deadline Extraction

Claude Refuses to Resolve Dates, Sorts Aug 30 After Sept 1

User Constraint: “Extract all deadlines sorted by date.”

Claude explicitly refused to calculate relative calendar dates (e.g. “by this Friday”), and then committed an elementary sorting blunder by placing the August 30 budget deadline after the September 1 items. ChatGPT and Gemini tied at 25/25 by correctly computing the exact weekday-date mappings.

Key Lesson: Always provide an explicit anchor date (“Today is Monday, August 24”) when asking AI to resolve relative deadlines.
👥 Ownership Hallucination Day 9 · Meeting Minutes

Gemini Claims Onboarding Docs “Unowned” Despite Volunteer

Transcript Fact: “Dev: I can take it but not until after the budget sheet.”

Gemini (19/25, Accuracy 3/5) listed “who will own onboarding docs” as an unresolved open question. However, the meeting transcript clearly showed Dev volunteering to take ownership the following week. Claude (25/25) accurately captured all action items, deadlines, and owners without dropping facts.

Key Lesson: In multi-speaker meeting transcripts, verify action item assignments against the raw conversation.

Scoring Standards

Methodology & Blind Evaluation Protocol

How ChatGPT, Claude and Gemini were run and blind-judged (60 answers), and why Grok is reported separately.

Criteria 1 · 5 Pts

1. Task Completion

Did the AI answer every component of the prompt without evasions, unprompted omissions, or truncated explanations?

Criteria 2 · 5 Pts

2. Factual Accuracy

Are all calculations, opening hours, flight assumptions, ingredient restrictions, and calendar dates verifiable and correct?

Criteria 3 · 5 Pts

3. Beginner Clarity

Is the tone accessible and natural for everyday non-technical users, free of unnecessary jargon and robotic preambles?

Criteria 4 · 5 Pts

4. Immediate Usability

Can a user copy and paste the output straight into their email, group chat, or planner without needing to clean it up?

Criteria 5 · 5 Pts

5. Format Compliance

Did the response strictly obey negative constraints, character ceilings (e.g. <280 chars), and structural requests (e.g. 5 bullets)?

The 3-Step Blind Judging Process (ChatGPT, Claude, Gemini)

1

Clean Execution

On August 28, 2026 each prompt was run through command-line tools, not the consumer apps: Codex CLI 0.145.0 (gpt-5.6-sol, reasoning effort xhigh), Claude Code (claude -p; model version not recorded) and Antigravity CLI (agy) 1.1.22 (gemini-3.1-pro-high). Subscription plans were not recorded.

2

Anonymization

The three answers to each task were stripped of model self-references and labeled A, B and C, with the answer key kept in a separate file.

3

AI Judge

An AI judge (claude-sonnet-5, run as a Claude Code subagent) scored A, B and C on the five criteria and wrote the rationale shown under each task: 300 scores (20 tasks × 3 models × 5 criteria). No human scoring. Because the judge is a Claude model, self-preference bias is possible.

🔍 Complete Transparency: Tooling Disclosures & Fixes

During our data collection and verification phases, we caught and corrected several tooling problems:

  • Grok Environment Isolation (separate Grok run, Sep 11–12, not blind-judged): Running the Grok CLI inside the repo workspace initially picked up local Korean instructions. Fixed: Re-executed in a clean /tmp sandbox with --system-prompt-override to guarantee 100% neutral English outputs.
  • Claude System Prompt Leak: Running Claude CLI inside the workspace inherited local prompt guidance. Fixed: Retested in an isolated, neutral directory.
  • ChatGPT CLI Truncation: An initial parsing script capped output at 4,500 characters, truncating extensive travel itineraries. Fixed: Buffer expanded to 15,000 characters and rerun.
  • Gemini File-Output Quirk: Gemini CLI returned local file paths for schedule tables instead of inline text. Fixed: Retrieved and verified raw generated files.

We re-ran the affected prompts after these fixes. One artifact remained and was scored as-is: a stray tooling preface at the start of one Day 23 answer, which the judge flagged.

Common Questions

Frequently Asked Questions

Which model should a complete beginner start with?

For most everyday beginners, ChatGPT is a reliable starting point: in our blind-judged comparison it had the highest average (23.85/25) and the most top finishes (10 of 20). Claude did best on the injury-aware workout plan, meeting minutes and apartment comparison; Gemini did best on the tweet, lyrics and contract tasks. Grok was tested separately and is not ranked.

Why did you use real everyday tasks rather than standard AI academic benchmarks?

Standard benchmarks like MMLU, GSM8K, and HumanEval test academic knowledge and programming synthesis. While useful for researchers, they don’t answer practical everyday questions like: “Can this model summarize my team’s messy group chat without dropping volunteer tasks?” or “Will this recipe builder invent ingredients I don’t have?” Our benchmark tests the exact friction points regular users encounter daily.

Which model versions and tools were used?

All runs used command-line tools on August 28, 2026: ChatGPT via Codex CLI 0.145.0 with gpt-5.6-sol (reasoning effort xhigh); Claude via Claude Code (claude -p), model version not recorded; Gemini via Antigravity CLI (agy) 1.1.22 with gemini-3.1-pro-high. Subscription plans were not recorded, so results in the free apps may differ. Grok 4.6 was run separately via the grok CLI on September 11–12, 2026.

What happens next?

We plan a full re-test of ChatGPT, Claude, Gemini and Grok on the same day with current versions, judged blind together. It will be published on this page when it is done.

Transparency

Corrections (October 17, 2026)

  • Scope: this page previously described a four-model double-blind benchmark (80 blind outputs, answers labeled A–D). Only ChatGPT, Claude and Gemini were blind-judged (60 answers, labeled A–C).
  • Judge: scoring was done by an AI judge (claude-sonnet-5, Claude Code subagent), not by people. Earlier wording such as “tested by real humans” and “scores frozen and timestamped” was removed.
  • Grok: Grok 4.6 answers were collected on September 11–12, 2026 without a blind step; its scores (average 24.35, “Top Average”, 15 top finishes) were removed from the scoreboard, matrix, winner labels, FAQ and structured data.
  • Model names: the page listed GPT-4o, Claude 3.5 Sonnet and Gemini 2.0 Flash. The models actually used were gpt-5.6-sol (Codex CLI 0.145.0), Claude Code with an unrecorded model version, and gemini-3.1-pro-high (Antigravity CLI (agy) 1.1.22). Plans were not recorded.
  • Counts: top finishes are now ChatGPT 10 (8 solo + 2 ties), Claude 8 (5 + 3), Gemini 6 (3 + 3); ties 4 of 20 (was 13). Averages are unchanged: 23.85, 22.30, 22.80.
  • Tweet task: Gemini's answer is 275 characters in the published data (was stated as 246); ChatGPT's is 251.
  • Quotes: the recipe and tweet constraints are now quoted from the actual prompts; the Day 23 prompt now shows a two-line lyrics excerpt instead of eight lines.
  • Removed: the promised 51-task expansion and the Next-Gen preview callout.
  • Next: a full same-day, four-model blind re-test with current versions is planned.
