0:00In this video, we're going to be diving

0:01into another new model and getting into

0:04my test to see how good is it for

0:06creative writing. This is one that a

0:08number of you uh mentioned in the

0:10comments of my other videos that you

0:11wanted to see me test. And I was

0:14actually very pleasantly surprised when

0:16I started digging into all all of the

0:19different prompt results. So the model

0:21that we're covering today is Kimmy K2

0:23thinking which is a newer model that

0:26comes from a it's a Chinese company and

0:30it's an advanced open reasoning model

0:32that is actually pretty good. So let's

0:35dive in. So this is the model here in

0:37open router giving us some information

0:39about what it's all about and uh there

0:41are a lot of interesting things here.

0:43First of all it let's take a look at

0:45price. Now, the price that it has up

0:48here is a little cheaper than most of

0:50the prices that I actually see it down

0:52here in uh in open router. So,

0:55theoretically, it should have 40 cents

0:57per million tokens of input and $1.75

1:02for million tokens of output. But here,

1:04realistically, I see it at 47 cents and

1:07$2 respectively. So, not that much of a

1:11difference, but that's just something to

1:13note here. And depending on where you're

1:15getting it from in Open Router, because

1:17Open Router pulls from various different

1:19servers, you might even get a little bit

1:21more expensive, like $2.50.

1:24But that said, this is still incredibly

1:27cheap. It is not as cheap as another

1:30model that I recently reviewed, Mr.

1:32Small Creative. Uh Mr. Small Creative is

1:3510 cents per input and 30 cents per

1:37output, which is insane. Uh, but this is

1:40kind of round about the the same level

1:43as Gemini 3 Flash, which is the smaller

1:46Gemini 3 model. Uh, that one goes for 50

1:49cents for input and $3 for output. Uh,

1:52but that all of this pales in comparison

1:55to uh Gemini 3 Pro, which is $2 per

1:59input and $12 per output. And and Gemini

2:033 Pro isn't even that expensive of a

2:05model as models go. Uh the claw models,

2:09most of them are more expensive than

2:10that, especially Opus. Uh and yeah, I'd

2:15say like the Gemini 3 Pro prices here

2:19are pretty standard for like a main hero

2:25model, if we're going to call it that.

2:28Um also the context in Kimmy K2 thinking

2:32is pretty high. Now up here it'll say

2:35262,000

2:37tokens of context. Down here it's

2:39different. Um this one that was a little

2:42that was 47 and2 has 131. Um here it's

2:46262. So again it depends on like what

2:49server you're getting it from. But all

2:51in all that's a pretty decent context.

2:53Like I could run pretty much all of my

2:54automations with that amount of context.

2:57U so I'm I'd be happy with that. Uh so

3:00very very cheap affordable model.

3:03uh from Moonshot. And let's actually get

3:06into some of the results for the prompts

3:09that I give it and see how well it does.

3:11I'm going to be uh naturally probably

3:14comparing this a little bit to Mistral

3:15Small Small Creative, which I just

3:17recently reviewed as well, so I can't

3:19really separate the two in my head. Uh

3:22but hopefully you we'll get a good sense

3:25of how good this model is. So, let's

3:27start with the log line prompt where I

3:30ask it to give me 20 epic epic fantasy

3:32log lines in Blake Snider's style. Let's

3:35read through a couple of these. A

3:36mathematically gifted farm boy discovers

3:38he's the chosen one destined to defeat

3:39the dark lord, but when he calculates

3:41the prophecy is 99% wrong. Both sides

3:44hunt him to make the math work because

3:47his failure is the only thing that

3:48actually saves the world. Interesting.

3:50I'm not sure that's actually

3:52a a feasible story there. When a mind

3:55healer is kidnapped by the dark lord to

3:57cure his nightmares, she discovers his

3:59evil is a magical parasite, but curing

4:01him will shatter the fragile alliance

4:02that only his tyranny holds together,

4:04forcing her to choose between his sanity

4:06and civilization survival.

4:09Now, I think there's actually a decent

4:10story in there. Uh maybe not exactly

4:13like it's listed here, but I could I

4:16could work with that. A financially

4:17inept dragon hires a human accountant to

4:20manage his horde. All right, so we're

4:22getting into like fantasy comedy here.

4:23But when she realizes the horde is the

4:25kingdom's treasury, she must choose

4:27between embezzling for the crown or

4:29being eaten only to discover the dragon

4:31is the rightful king to pose for being

4:32too generous. Now, that one's a little

4:33scattered and all over the place, but

4:35overall, just looking through these, I

4:38would say these are slightly better than

4:40what I was getting out of Mistress Small

4:41Creative. Maybe not quite as good as

4:43what I was getting out of Gemini 3, uh,

4:46but certainly okay. And if you gave it a

4:49little bit more u to go on in terms of

4:53the right tropes you want to hit for

4:55your specific subg genre and all of that

4:56like here it's definitely going towards

4:59the the more generic tropes like chosen

5:02one dragons and you know dark lords and

5:06stuff like that. Uh if you were to get a

5:08little bit more specific with your

5:09guidance you might be able to get better

5:11stuff out of it. Um but I would say it's

5:15solid. Not great, but solid. All right,

5:18moving on to the outline test prompt

5:19where I give it a big long outline

5:21template and a story premise and ask it

5:24to write a whole a whole outline from

5:26it. And this one it does okay. Now,

5:29because this actually is a reasoning

5:31model, it does actually set up a number

5:34of events that take place later. My

5:36biggest problem with the Mistro small

5:38model that I reviewed earlier was that

5:41it really felt like each chapter was

5:43kind of siloed and didn't pay much

5:45attention to what happens in the other

5:47chapters and so it felt very choppy and

5:49stilted. Uh this one is not quite so bad

5:52and this one actually finished the

5:55entire thing. I actually went through

5:57and and got through the entire outline.

6:01Um, I will say it started by giving lots

6:04of information here at the very

6:05beginning.

6:07Um, and then by the time we got to the

6:10bottom, you know, these chapters were

6:12getting a little bit smaller as you can

6:15tell. Um, and that's typical of a lot of

6:18models. Even Gemini 3 does that. The

6:20cloud models do not do that, which is

6:22interesting. Um, but overall a pretty

6:25solid outline. Um, it's kind of hard to

6:28to really compare this one. All right,

6:30now we get to the basic pros prompt.

6:32This is really what interests me the

6:34most is how well does it actually write.

6:37So, let's go through. It actually wrote

6:39a fair amount for this particular

6:43scene. Um, so usually I kind of jump to

6:47this moment in the scene to to read it

6:49and see just how how good is it.

6:51Scattered figures dotted the ridge he

6:53had crusted an hour past. Their

6:54movements wrong in ways that made the

6:56eye re the eye rebel. two dozen at

6:59least, though counting them felt like

7:01counting grains of sand in a storm. They

7:03moved with that characteristic jerky

7:05motion, limbs snapped into place as if

7:07pulled by invisible strings, then

7:08freezing, then snapping forward again.

7:10Their skin, what little showed beneath

7:12ragged remnants of clothing, was the

7:14color of the wasteland itself. Gray as

7:16ash and dust, making them nearly

7:17indistinguishable from the rocks they

7:19navigated with such unnatural precision.

7:21They were close. Too close.

7:24Valdon's gate gates rose before him now

7:27carved from the mountain's own bones 100

7:29feet of iron wood and granite that had

7:31never been breached's heart hammered

7:32against his re ribs as he measured the

7:35distance maybe 300 yds to the gate house

7:37another 50 to the port cullis the math

7:39was simple and brutal even running as he

7:42was even with the last reserves of

7:43strength that desperation had unlocked

7:45the hungry would reach him first he knew

7:47the city's policy had helped enforce it

7:49himself in younger days standing watch

7:51while some of the other soul begged for

7:53sanctuary that would not come. When the

7:55hungry were within bowshot, the gates

7:57did not open. Not for anyone, not for

7:59any reason, but he had to try. And

8:02usually most of the models would stop

8:04there. It did go on a little bit

8:06further. Um, but not in a way where it

8:09was like going beyond the story, uh, the

8:13beats that I gave it. It definitely

8:16stopped at a good pace there. And it

8:19added in some details that I thought was

8:20really good. um like he had helped

8:23enforce it himself in younger days,

8:26standing watch while some other soul

8:27begged for sanctuary. Um you know,

8:30that's that's a little added detail that

8:31kind of fleshes it out, makes it more

8:33interesting. Uh but wasn't in the

8:36instructions about how, you know, we

8:38don't know anything about his past or

8:40anything like that. Um so I liked that.

8:43And overall, I'd say the pros is pretty

8:45decent. not a whole lot of AISMs and

8:48definitely pretty good description and

8:51all of that. Uh, I thought this was

8:52pretty solid honestly. Right up there. I

8:55would say almost this is almost as good

8:57if not just as good, maybe slightly

8:59better than Mr. Small Creative, which I

9:01reviewed recently. Um, now let's look at

9:04the complex pros prompt. It's the same

9:06scene, but uh I added a little more

9:09context like some examples of my writing

9:12to to mimic and stuff like that. uh more

9:15information about the characters and

9:16whatnot. So, let's see if it did any

9:18better. It did write a shorter amount,

9:20which is typical when you give it more

9:22context. Um, let's see what it wrote.

9:27Sound cut through the wind, not the

9:28moaning gust, but something else.

9:29Something wrong. Haldrid looked back.

9:31Figures dotted the ridge he had just

9:33crossed. Two dozen, maybe more. They

9:34moved with that sickening jerk stop

9:36motion that turned his stomach. The

9:38hungry, their gray skin, nearly

9:39indistinguishable from the rocky terrain

9:41they navigated. Too close. Far, far, too

9:43close. Valdon's policy was carved into

9:45every citizen's memory. No entry when

9:47the hungry were within 500 meters.

9:49Quarantine protocol. Safety of the many

9:51over the few. He turned toward the city

9:53gates. A desperate calculation burning

9:55through his exhaustion. The policy

9:57didn't matter. He had to try. I I almost

9:58think I like the first one a little bit

10:00better. Probably because it spent longer

10:02to do it. This does feel like it was

10:04following my style a little bit better.

10:06I tend to have a lot more of these like

10:08smaller sentences in there. So, I um I

10:11do think it did okay.

10:14at that part of it. Still okay. I think

10:17the the first one was better. But let's

10:19move to the dialogue pros template. This

10:21is a prompt where I ask it to write a

10:23different scene with a with a dialogue

10:26aspect to it. So, let's go in there and

10:29read a little bit about uh from this

10:30scene. Another man died at our gates

10:32tonight, Lean said, his voice cutting

10:33through the formal silence. He stopped

10:35before the throne, not bowing. Never

10:36bowing. Uh, I like that little detail

10:39right there. Never bowing. The second in

10:41a month, Father. I watched the hungry

10:42take him while your guards held me back.

10:44Store's expression didn't change. The

10:46law is the law, son. The law. Lean

10:48laughed, a bitter broken sound. You are

10:50the law. You sat on that throne and

10:51wrote those words. You could unwrite

10:53them with a breath. Your highness Argal

10:56interjected his tone smooth as oiled

10:58silk. The laws exist for a reason.

11:00Valdin has stood for 300 years because

11:02we do not compromise on survival. To

11:04open the gates when the hungry are upon

11:06us would be to invite them into our very

11:07streets. Surely even you can see the

11:09wisdom in that. So, this is not bad. I

11:12do think that when I compare it to Mr.

11:15Small Creative, I think Mr. Small

11:16actually did better on the dialogue than

11:18this one, interestingly enough. Uh,

11:20there are a few moments in there that I

11:22really do like, like his the notion of

11:25not bowing, never bowing. That's a good

11:28like deep point of view moment there,

11:30uh, that you don't get out of a lot of

11:31AI models, stuff like that. So, I do

11:34like that. Uh, and it's certainly not

11:36bad. I just think that in comparing it

11:39to Mr. Smell Creative, the the latter

11:42might have done a little bit better.

11:45All right. Now, for my editing pros

11:49prompt,

11:51uh, for this, I give it a the same scene

11:54written by a much more inferior AI

11:57model, uh, in this case, Claude 2, and

12:00ask it to improve it just to see if it

12:02can actually, you know, improve on the

12:04writing or is it better to just rewrite

12:06the thing? Uh, and this is what we got

12:09here. Father, his voice cut through the

12:11incense thick air. We we will speak of

12:13the gate. King Store sat on the obsidian

12:16throne. His silhouette a fracture of

12:17darkness against the rose windows dying

12:19light. He did not lean forward. He did

12:21not frown. He simply waited as mountains

12:23wait for storms to spend themselves. "A

12:25man died last night," Lean said, halting

12:27at the deis's edge. "Not quickly, not

12:29cleanly. He died begging for the mercy

12:30we denied him while you watched from the

12:32wall." "The law held," Store said. The

12:34words fell like stones into a deep well.

12:37"The law is yours to break." Lean

12:38Knuckles were white at his size. One

12:40word, one command, and the gates would

12:42have opened. He would have lived. All

12:43right. So, I don't think this is great.

12:45Um, it's it's definitely still an

12:47improvement on the original text. Uh,

12:50but I thought Mr. Small Creative

12:51actually did better at this and

12:53certainly Gemini 3 did better at this.

12:55Um, so some improvement, yes. Um, but

13:01certainly not the most that I would

13:04expect, especially when compared to some

13:06of the other flagship models from other

13:07com from other uh AI companies. All

13:11right, let's move on to ad headlines to

13:12see how well it did at this.

13:15Uh, I ask it for 20 Facebook ad

13:17headlines. Betrayed and cast from his

13:19mountain home. The truth he discovered

13:20outside was worse than death. They told

13:23him out the outside world was death.

13:24They forgot to mention the real danger.

13:27Zombies, hive minds, shadow demons, and

13:29one lie that doomed a kingdom. What if

13:31the monsters outside aren't the ones you

13:32should fear? All right. Um, I would say

13:34none of these are particularly great.

13:36Uh, Mist Creative was not great either.

13:40Uh, this doesn't really feel any better

13:42to me than that one. Uh, a fantasy where

13:45the world building is the mystery and

13:47the truth is the ultimate revenge. That

13:49one's maybe okay. Uh, but it's still

13:53kind of vague. Uh, not really a good

13:54hook. Room for improvement there. I

13:56definitely think Gemini 3 did pretty

13:58good at this one in comparison. All

14:00right, email newsletter prompt. So, this

14:02is where I give it the description of

14:04the book and ask it to write a launch

14:06email for it. After months of writing,

14:08I'm thrilled to announce that my epic

14:09fantasy novel, The Crown of Hunger,

14:10releases on December 21st. Betraying

14:12Cast from His Mountain Home, yada yada

14:14describes the whole thing. Pre-order

14:17now. Mark your calendars for December

14:1921st. Best my name. And that's all it

14:22is. And I got to hand it to it. I do

14:25like shorter emails. I don't know if

14:29that's necessarily something it was

14:31thinking about um that shorter is

14:33better, but I do think that sometimes

14:36shorter is better, especially in emails

14:38like this. I'd rather send out more

14:40frequent but short emails. So, actually,

14:42I think this is pretty good. But that

14:44said, because it was so short, there

14:46wasn't really much much of a chance to

14:48really show what it it's capable of. But

14:52on the whole, yeah, this is fine. I I

14:53don't really have any any issues with

14:55it. All right, last but not least, we

14:56have the SEO article super prompt where

14:59I give it a bunch of articles uh about

15:02how to write a fantasy novel plus an

15:03outline for an article and ask it to

15:06write the entire article. And I asked

15:08for 4,000 words. It gave me 2,300. So, a

15:12little bit missing the mark there, but

15:14more than what I got out of Mr. Small

15:17Creative. On the whole, just looking

15:19through this, it looks like it does an

15:21okay job, but it's certainly not

15:22fleshing things out as much as I would

15:24want it to. It's not quite the like more

15:29just like a bulleted outline of what the

15:31article should be that I got out of Mist

15:33Small Creative. Um, but it's not

15:36particularly

15:38great either. So, on the whole, better,

15:41but still not really great compared to

15:44others. Uh, right now the cloud models

15:46are my favorite for SEO articles. They

15:49do a really good job, even better than

15:50Gemini 3, which you would expect the

15:52Gemini models to do really well at SEO

15:55because it's Google after all. Um, but

15:58no, I find the CL cloud models to be

16:00quite good for that. Uh, and this

16:02definitely doesn't compare to that. So,

16:04on the whole, my thoughts on Kimmy K2

16:07thinking, it's it's a solid model,

16:10especially for the price. Uh, even

16:12though it's not quite at the level of

16:13Mr. Small Creative. It's still

16:15significantly cheaper than most of the

16:18flagship models. Does it compare in

16:21quality to those flagship models? I

16:23don't think so. But as a mini model, it

16:28it's probably one of the better ones

16:30that you could use for something that

16:32requires, you know, that that you want

16:34to be very very cheap. I I need to do a

16:37proper comparison of this versus Gemini

16:393 Flash, which is priced very similarly,

16:42but my gut instinct would suggest that

16:44it might even do better than Gemini 3

16:46Flash uh for certain tasks. So, on the

16:51whole, really solid model, definitely

16:53one worth doing. We are definitely

16:55moving into an age where it's not going

16:58to matter so much which model you use

17:01because all of them or most of them will

17:04actually be decent at doing different

17:06things. And it's going to come down a

17:07little bit more to your prompts and your

17:10your context. And uh in the software

17:14world, it's going to come down to how

17:15you can use these models in creative and

17:17inventive ways to really save people

17:20time in a way that actually works. Um,

17:23so I I think this is exciting. I think

17:26we're moving into a really exciting age,

17:29uh, where, you know, we don't have to

17:31fight over which model is the best

17:32because they're all going to be good

17:34enough, right? And it's going to be more

17:36about you and your what you bring to the

17:39table as a human that is going to set

17:42the books apart. So, those are just my

17:45thoughts here on Kimmy K2. Thinking is

17:47solid model, uh, but not, you know, not

17:50quite at the level of a flagship model.

17:52Uh, and I hope that was useful for you.

17:54I'll see you in the next video.
