Guide: How Claude Differs from ChatGPT
The article explains why millions who download Claude but use ChatGPT-style prompts often miss Claude’s strengths. Independent benchmarks cited show Claude leads on reasoning by 14.6 points, has a 7-point advantage on instruction compliance, and won four of eight blind writing tests. The piece is a practical translator: it describes how Claude’s Constitutional AI training affects its responses, recommends shifting from command-style prompts to situation descriptions, and provides six ready-to-use prompts (Quick and Full versions) plus a step-by-step getting-started guide and project setup templates. The author also outlines tradeoffs (image, voice, speed, Custom GPTs marketplace) and includes demo conversations intended to convert skeptics.
Practical guidance and benchmark claims about LLM behavior can affect how teams adopt and operationalize conversational AI, but this is a usage/education piece rather than a platform policy, technical release, or major commercial milestone.

Claude vs ChatGPT for Code Review
A DEV Community post (The AI Leverage Weekly) compares Claude and ChatGPT (GPT-4o) for automated code review workflows. The author reports that GPT-4o (ChatGPT) is faster and better for conversational, iterative reviews of short functions or snippets, while Claude (Sonnet/Opus) handles larger context windows, produces more structured output, and surfaces deeper logic and security issues in full-file or multi-file reviews. The article includes a reusable prompt template the author uses with Claude that asks for a structured review (critical issues, design concerns, minor improvements, questions). The recommendation: use ChatGPT for quick snippet iterations and Claude for serious pre-merge module reviews.
Claude Skills: Seven Laws from 75 Tests
This guide explains why reusable Claude "Skills" have supplanted prompt libraries for many workflows and presents seven empirically derived rules (from 75 tests) plus an audit checklist and an automated improvement prompt. The piece also summarizes recent AI infrastructure and model news: Anthropic announced a SpaceX compute deal giving access to Colossus 1 (300+ MW, ~220,000 NVIDIA GPUs) and raised Claude usage limits; Anthropic published Natural Language Autoencoders as an interpretability tool and shipped a "dreaming" background process for Claude Managed Agents; OpenAI released GPT‑Realtime‑2 (a voice-capable model with GPT‑5-class reasoning and a 128K context window); and several startups (Cognition AI, Thinking Machines) and tooling updates are noted. The author (Aakash) provides practical, test-backed guidance for writing, structuring, and continuously hardening Claude skills for production use.
Prompt to Transfer ChatGPT Settings to Claude
t3n reports a prompt-based method to migrate personalized settings and preferences when switching between AI chatbots (e.g., ChatGPT to Claude). Claude provides a built-in import template accessible via a button labeled "Import starten" under its "Fähigkeiten" section; users can copy an export prompt into their source chatbot and paste the resulting output back into Claude to import settings. Prompt expert Susanne Renate Schneider published a more detailed prompt to capture additional user preferences (communication style, terms to avoid, workflow habits) because the standard template can miss data from heavy ChatGPT users. The t3n MeisterPrompter podcast tested these prompts across ChatGPT, Claude, Gemini and Le Chat; the Claude import worked smoothly, while Gemini presented an obstacle. The episode includes the extended prompt and a solution for Gemini issues.
