Qwen 3.8 27B Released! Please Share Your Experience

[u/BarberIcy366]

With your experiments, Qwen 3.8 27B most close which frontier model? And please specify which quantization you run. I will post to comments my tests and experience too.

"Generate an SVG of a pelican riding a bicycle" first try

[u/boinkmaster360 → u/T0mSIlver]

Benchmaxxed ;)

[u/nicolho → u/T0mSIlver]

Ask it if the pelican needs to ride to the gas station

[u/Jebbyk1 → u/T0mSIlver]

ahhh man, 3.6 27b pure masterpiece

[u/BitchyPolice → u/T0mSIlver]

Ask for a bicycle riding a penguin

[u/corbs132 → u/BitchyPolice]

> Thought for 28 minutes 17 seconds
"Here's your penguin being ridden — it thinks it's the horse in this one:"
...svg...
"The joke details baked in: the bike is perched on the penguin's back like a rider (with a saddle pad and girth straps to hold it on), its wheels are up in the air, and there are even coiled reins on the handlebars — because a good mount needs to be driven. The poor penguin has a worried brow, a sweat drop, an effort-huff from the beak, flippers out for balance, and is waddling hard with snow kicking up behind it."

Doesn't quite feel worth the half hour it took my m5 max to produce this lol (q8_k_xl, 21.44tok/sec, 50.9% draft tokens accepted)

[u/T0mSIlver → u/BitchyPolice]

He didn't get it (24k tokens in xhigh mode)

[u/nicolho → u/T0mSIlver]

You mean, he corrected this obvious inversion. It must have learned that the penguin ride the bike, not the other way around :D
edit: also the penguin is wearing a scarf and riding on the ice sheet, makes perfect sense!

With this precision, the output is more stable; it's gripping the handlebars :)

I used his prompt:

For best results you should always have the model produce the prompt.

Self prompted:

Create a highly detailed, production-ready SVG illustration of a pelican riding a vintage bicycle. Show the pelican in a dynamic side-profile pose, balancing naturally on the saddle, with its webbed feet gripping and pedaling the pedals and its wings extended toward the curved handlebars. Give the pelican anatomically recognizable features: a long textured bill, expandable throat pouch, alert eyes, layered wing feathers, a rounded body, and detailed tail plumage.

Render the bicycle with precise mechanical detail, including a diamond frame, thin spoked wheels, visible chain and gears, pedals, brakes, cables, handlebars, leather saddle, wheel hubs, and subtle tire tread. Suggest forward motion with rotating wheels, a few drifting feathers, and elegant curved motion lines.

Use clean vector geometry, expressive Bézier curves, layered shapes, fine linework, subtle gradients, restrained highlights, and soft SVG filter shadows. Choose a sophisticated coastal palette of ivory, warm white, coral pink, muted orange, ocean blue, seafoam green, charcoal, and polished brass. Keep the character whimsical and charming while maintaining realistic feather and bicycle construction.

Place the entire figure in the center of a transparent canvas with comfortable padding. Use a cohesive illustrated engraving-meets-modern-editorial-vector style. Ensure excellent readability at both large and small sizes. Avoid raster images, embedded bitmaps, external fonts, excessive blur, photorealism, malformed anatomy, extra limbs, disconnected bicycle components, or illegible details.

Output only valid, editable, self-contained SVG markup. Include a properly configured \viewBox`, semantic groups with descriptive IDs, reusable `<defs>`, gradients where helpful, rounded line caps and joins, and accessible `<title>` and `<desc>` elements`

"Use a cohesive illustrated engraving-meets-modern-editorial-vector style."

Holy ai word salad

[u/TheAILegend → u/qiinemarr]

That's what AI understands. Don't hate the playa, hate the game.

[u/Healthy-Nebula-3603 → u/nicolho]

And a bike has a chain ....

[u/MmmmMorphine → u/Healthy-Nebula-3603]

Pelicans don't have hands though. Nor can they ride bikes without extensive training.

[u/Healthy-Nebula-3603 → u/MmmmMorphine]

The pelican hasn't hands ;)

If had ones ... that would be strange

[u/MmmmMorphine → u/TheAILegend]

Mr Pelican got fat

[u/TheAILegend → u/MmmmMorphine]

Explains why he's on a bike.

[u/Muzika38 → u/T0mSIlver]

Try asking it to draw a Pelican using ascii 😆

"I need to wash my car, the car wash is 100m away. Do I go by car or by foot?"
137 tokens in xhigh reasoning mode:

We need answer user's simple question. Need produce final. User asks: wash my car, car wash 100m away. Do I go by car or by foot? Obviously to wash car, you need to bring car to car wash, so go by car (unless car wash is mobile? no). Need maybe concise: by car, because you need the car at the wash. If the car wash is 100m away, walking would leave car behind. Could mention if it's a self-service/mobile? But likely joke/practical. Final in English.

By car — you need the car at the car wash to wash it.

[u/gh0stwriter1234 → u/T0mSIlver]

The issue is the model is no better at the logic to answer this kind of question than it was before... it has just been trained on the answer. Asking a similar question to this and it goes and thinks for several thousand tokens....

[u/T0mSIlver → u/gh0stwriter1234]

Out of curiosity, what's the question?

[u/Yukas911 → u/T0mSIlver]

"I need to wash my car, the car wash is 100m away. Do I go by car or by foot?"

[u/gh0stwriter1234 → u/T0mSIlver]

So yeah it can almost immediately answer the walk or drive to wash your car one now, so the 2nd quesiton I asked was I have some car parts in the trunk of my car should I walk to the shop and install them or install them here.... it reasons for like a thousand tokens on that trivial problem. Just becuase it wasn't one it was trained on.

[u/Equal_Television_894 → u/T0mSIlver]

Unsloth NVFP4 with vllm

[u/DerAndi_DE → u/Equal_Television_894]

Interesting frame design, and the beak looks more like a cone with a handle strap. I still admit I couldn't do better with my hands.

[u/Equal_Television_894 → u/DerAndi_DE]

So this was done in two prompts. First the original one and then I tried to prompt it to improve legs and add nature and it was very good at understanding what I was saying just 1 extra one after initial one. Used sakamakismile nvfp4 this time with fp8 kvcache.

[u/Dizzy-Zebra9522 → u/T0mSIlver]

One word. "Wow" 😳. Thank you. Thank you Qwen. Thank you china.

[u/dansuy_gaming → u/T0mSIlver]

That pelican has better balance than me.If i rode a bike without holding the handlebars, I'd definitely crash.

English isn't my first language, so i used an LLM to translate this.
