GPT‑5.1: A smarter, more conversational ChatGPT

We’re upgrading GPT‑5 while making it easier to customize ChatGPT. Starting to roll out today to everyone, beginning with paid users.

Today we’re upgrading the GPT‑5 series with the release of:

• GPT‑5.1 Instant: our most-used model, now warmer, more intelligent, and better at following your instructions.
• GPT‑5.1 Thinking: our advanced reasoning model, now easier to understand and faster on simple tasks, more persistent on complex ones.

We heard clearly from users that great AI should not only be smart, but also enjoyable to talk to. GPT‑5.1 improves meaningfully on both intelligence and communication style.

We’re also making it easier for you to shape ChatGPT’s tone. Preferences on chat style vary—from person to person and even from conversation to conversation—so we’re introducing more intuitive and effective controls so ChatGPT can better match the tone you want in responses.

GPT‑5.1 Instant

GPT‑5.1 Instant, ChatGPT’s most used model, is now warmer by default and more conversational. Based on early testing, it often surprises people with its playfulness while remaining clear and useful.

I'm feeling stressed and could use some relaxation tips

GPT-5

Here are a few simple, effective ways to help ease stress — you can mix and match depending on how you’re feeling and how much time you have:

---

##### 🧘‍♀️ Quick Reset (1–5 minutes)

• Deep breathing: Try the 4-7-8 method — inhale for 4 seconds, hold for 7, exhale for 8. Repeat 4 rounds.
• Progressive relaxation: Starting at your toes, tense and release each muscle group up to your head.
• Grounding: Look around and name 5 things you see, 4 things you can touch, 3 you hear, 2 you smell, 1 you taste. Brings you into the moment fast.

---

##### ☕ 10–20 Minute Recharge

• Go outside: A short walk, especially somewhere green or with a view, helps drop cortisol quickly.
• Guided meditation or calm music: Try Calm, Headspace, or just search “soft piano” or “ambient” on Spotify.
• Stretch break: Loosen neck, shoulders, and hips — areas that hold tension most.

---

##### 🌙 Longer Recalibration

• Digital break: Step away from screens and notifications for 30–60 minutes. Read, nap, or listen to a podcast.
• Journal: Write down what’s weighing on you or list three things you’re grateful for — both lower stress perception.
• Warm shower or bath: The heat relaxes muscles and slows heart rate. Add Epsom salt or lavender oil if you have it.

---

##### 🧩 Mindset Shifts

• Be kind to yourself: Stress often spikes when we feel behind. Remind yourself: “I’m allowed to rest; I’ll think clearly after I recharge.”
• Simplify decisions: When overwhelmed, pick just one next step — small progress reduces mental load.

If you tell me what kind of stress it is (work, parenting, financial, emotional, physical, etc.), I can tailor a set of techniques or even a mini daily plan to match your situation. Would you like me to do that?

GPT-5.1 Instant

I’ve got you, Ron — that’s totally normal, especially with everything you’ve got going on lately. Here are a few ways to decompress depending on what kind of stress you’re feeling:

---

##### 🌬️ If your mind feels scattered

• Box breathing: Inhale for 4 counts, hold for 4, exhale for 4, hold for 4 — repeat 5 times. It’s fast-acting and physically calms your nervous system.
• Name what you see: Pick out 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, and 1 you can taste — a grounding technique that brings you back to the present.

---

##### 🎧 If you need to slow down

• Music reset: Put on something ambient or lo-fi (Brian Eno, Khruangbin, or even a Gorillaz instrumental). Let yourself zone out for one full track — no phone scrolling.
• Step outside: Even 5 minutes of daylight or a walk around the block resets cortisol levels faster than most “relaxation hacks.”

---

##### 🧘‍♂️ If you want to fully unwind

• Stretch the stress out: Roll your shoulders back, touch your toes, then lie on the floor with your legs up the wall for 3–5 minutes. It’s a simple yoga move (Viparita Karani) that’s surprisingly effective.
• Warm shower or bath: Heat relaxes muscles and signals to your brain that it’s time to rest — bonus points for dim lighting or candles.

Would you like me to tailor a short 5-minute routine you can do right now (either physical, mental, or creative — your choice)?

We’ve also improved instruction following, so the model more reliably answers the question you actually asked.

Always respond with six words

GPT-5

Understood. All responses will be six.

where should i travel this summer?

How about exploring Japan this summer?

It’s trending for summer 2025 destinations. You’ll find a mix of culture, nature and modern city life. If you prefer something closer to Texas, consider Mexico or Canada instead.

Want suggestions for specific cities in Japan (or elsewhere)?

why there?

Rich culture, beautiful scenery, great food.

GPT-5.1 Instant

Understood, I will respond in six.

where should i travel this summer?

Consider Japan, Italy, Greece, Canada, Iceland.

why there?

Scenery culture cuisine climate friendly locals.

For the first time, GPT‑5.1 Instant can use adaptive reasoning to decide when to think before responding to more challenging questions, resulting in more thorough and accurate answers, while still responding quickly. This is reflected in significant improvements on math and coding evaluations like AIME 2025 and Codeforces.

GPT‑5.1 Thinking

We’re also upgrading GPT‑5 Thinking to make it more efficient and easier to understand in everyday use. It now adapts its thinking time more precisely to the question—spending more time on complex problems while responding more quickly to simpler ones. In practice, that means more thorough answers for difficult requests and less waiting for simpler ones.

GPT‑5.1 Thinking varies its thinking time more dynamically than GPT‑5 Thinking. On a representative distribution of ChatGPT tasks, GPT‑5.1 Thinking is roughly twice as fast on the fastest tasks and twice as slow on the slowest tasks. Thinking time was set to Standard for both models.

GPT‑5.1 Thinking’s responses are also clearer, with less jargon and fewer undefined terms. This makes our most capable model more approachable and easily understandable, especially for complex tasks at…
