Chat Around Filters, Stress-Test Your Preparedness, Get Honest About Startup Potential, and Uncover Past Selves with These Prompts

• ​Casual Chat Without Filters: What Actually Works: Community thread on “uncensored” small talk without jailbreaks. Suggestions lean toward tone-steering, clearer boundaries, and models built for companionship or local OSS options—rather than filter-bypass prompts that get patched. Useful if you want warmer, more candid chats without tripping safety rails.
• ​Five Survival Prompts To Stress-Test Preparedness: Five scenario prompts—urban blackout, water outage, bug-out bag, family plan, mental resilience—turn AI into a stress-test partner. Each forces concrete actions, time windows, and resource constraints so you can expose gaps now instead of during an emergency.
• ​Startups: Five Prompts for Brutal Reality Checks: Founder-focused prompt set: investor-style teardown, competitor unfair advantages, 12-month cash-flow stress test, customer interview simulation, and scale-up bottleneck detector. Practical scaffolds that surface blind spots before you burn runway.
• ​Prompt Hacks for Travel, Startups, Code, Marketing: Compact patterns that travel well: itinerary builder with time-slot table, brutally honest startup advisor, senior-engineer refactor with trade-offs, social hooks under 10 words, and live interviewer loop. Good “one-liners” you can reuse across projects.
• ​Personality Archaeology Dig: Excavating Past Selves: A narrative prompt that treats self-reflection like a structured dig: excavation methods, “artifact” preservation, timeline reconstruction, and a culminating discovery about which “buried self” drives present behavior. Great for coaching/journaling sessions that need structure and stakes.

ChatGPT Has Upgraded (and Downgraded) Its 'Thinking' Model

ChatGPT has answered complaints over how long it takes to get an answer out of its "5 Thinking" model by breaking it into four submodels (Light, Standard, Extended, and Heavy).

The fragmentation comes at the expense of the "5 mini-Thinking" model, which was incorporated into its larger counterpart.

Essentially, you're now getting four reasoning models instead of two.

This allows you to customize the amount of reasoning power you allocate to the model per input. So, let's say you want to start by cracking your problem wide open with "Heavy" thinking, but then you have some lower-level follow-up questions that don't require as much of a response.

You can just click the chatbox's drop-down and pick the reasoning power you feel is best for that particular question. Click here to see the full experiment that I ran on the same prompt. It'll give you an idea of what to expect:

Oboe Makes AI Courses to Your Specs

Oboe (launched this week) bills itself as the first “generalized” AI learning platform, turning any prompt into a tidy, shareable mini-course in seconds. Instead of loose chat replies, Oboe structures topics into lessons, summaries, memory aids, quizzes, and optional audio, then recommends related rabbit holes so you steer the journey—not an ad feed.

Built by Anchor cofounders Nir Zicherman and Mike Mignano, it aims to make learning lightweight, fast, and fun, with built-in fact-checking systems to reduce AI errors. The free tier lets you create up to five courses; paid plans unlock more. Early feedback praises the clean UI and requests tweaks like wider reading space and “now-playing” highlighting in audio—both on the team’s list.

On the roadmap: course editing, non-English support, video lessons, and tone controls. For curious self-learners, educators, and teams, Oboe is a compelling, structured alternative to aimless browsing.
