Asked Codex in Buzz to configure setting up Devin with Kimi and Cursor with Grok, and it did it. Now the whole gang is here. 5.6 Sol is default, Fable 5, Kimi K3, and Grok 4.5.

Kimi K3 beating Fable and Sol on price and quality. Command Code's internal flappy bench results are in. Really impressed with the results. For Kimi K3 we set the gameplay to hard while Fable 5 and GPT-5.6 Sol were set to easier. Cost breakdown: • Kimi K3: $0.024 •Fable 5: $0.42 •GPT-5.6 Sol: $0.15 Ranking based on DX & features: •Kimi K3: 8/10 •Fable 5: 7.5/10 • GPT-5.6 Sol: 7/10 GPT 5.6 Sol max can definitely go on longer and wins the game overall, but that's something different. Grok 4.5 beats GPT 5.6 Sol on that, lol.Mm-hmm.

Kimi K3 vs GPT-5.6 Sol vs Fable 5 Three top-tier models. Same /design prompt across all. Parameters reviewed: Pace, design sense, gameplay feel Result: Kimi K3 nails the design sense and knows exactly what to add in-game. Pace and gameplay held up well. Fable 5 and GPT-5.6 Sol both play too fast, video isn't sped up. Ranking (DX, Features & Cost): → Kimi K3: 9.5/10 · $0.030 → Fable 5: 7.5/10 · $0.38 → GPT-5.6 Sol: 7/10 · $0.11

Kimi K3 just 3 shotted a whole walkable voxel town with drivable cars — Voxelville, around $3.24 in API usage. The same token cost would be $10.80 with Fable 5 and $6 with GPT 5.6 Sol. Fable 5 built its own Maplewood, GPT 5.6 Sol built Willowwick, but on price/quality Kimi K3 just cooked both of them. The era of free indie game development is closer than you think!

Kimi K3 vs GPT-5.6 Sol. I reused the 3D globe test from Kimi vs Fable 5. Same prompt. Same reference image. Kimi K3 left. GPT-5.6 Sol right. Kimi edges out Sol on UI fidelity and globe realism. At current API prices, Kimi is about 50% cheaper. For frontend work, it's my pick.

OFFICIALLY SAYING KIMI K3 IS BETTER THAN CLAUDE FABLE-5 AND GPT-5.6-SOL FOR FRONTEND DEVELOPMENT Tried building a macOS-style UI for an AI operating system with Kimi K3. This whole thing took about 15 minutes from a single prompt.

Kimi K3 vs Fable 5. Same prompt and reference. 3D globe dashboard. Kimi left, Fable right. To me, Kimi's UI fidelity is a touch better. The globe looks better too, with richer textures and smoother motion. This task: ~$3 with Kimi, ~$15 with Fable. I'd pick Kimi k3 for frontend work.

GPT-5.6 Sol vs Fable 5 vs Grok 4.5 Built a car racing game with a UX-over-UI focus, using /design command. Parameters we reviewed: Car speed, crash behavior, scoring, smoothness, and feel. Results: Grok 4.5: best overall performance Fable 5: a close second, nearly matching Grok 4.5 GPT-5.6 Sol: great UI, weak gameplay (excess drift and friction) Ranking (based on actual gameplay): - Grok 4.5: 9/10 - Fable 5: 8/10 - GPT-5.6 Sol: 7/10 (UI was 10/10, gameplay wasn't)

It worked!! Kimi k3 Oauth is now wired directly into codex. The Kimi k3 model is insane but their app is not. So I figure a better way to use k3 by hooking my sub straight into codex instead. K3 now sits in the model picker next to Sol 5.6. Same subscription i was already paying for, no api key, just have to do OAuth in Kimi Code. Links down below 👇

Running top-tier models like Claude Fable 5, Kimi K3, and Grok 4.5 inside Codex is now completely possible using a straightforward open-source repository. Here is how you can set it up right now: - Locate and open the opencodex repository - Copy the prompt instructions directly into your chat window - Follow the detailed guide linked below to configure your setup and start running queries This workflow bypasses complex installations and lets you leverage multiple frontier models within a single interface. Bookmark this post so you do not lose the step-by-step walkthrough.

Just tested Kimi.ai K3 against GPT-5.6 and Grok 4.5 on the same task: build a Subway Surfers game. Kimi K3 was my favorite. Better UI, smoother gameplay, and the overall experience felt more polished. GPT-5.6 was solid too, while Grok 4.5 fell behind on the UI. The interesting part is that all three needed at least one follow-up prompt. Kimi also took a bit longer to generate, but the extra time paid off. Ran Kimi K3 through Nebius Token Factory. Low inference cost + a really capable open source model is a great combo.

Kimi K3 vs GPT-5.6 Sol Difference in taste is so stark , like if i swap kimi k 3 name with fable 5 people will trust it but this is not only about visuals , its also about function , you can see both achieve same result but the way to achieve is different kimi is more creative

I asked Grok 4.5 to build macOS 27 with real Liquid Glass and native apps… It delivered in under 10 minutes. Kimi needs 3+ hours. This is the result. Live demo below 👇

Fable 5, Grok 4.5 and GPT-5.6 ran the same builds simultaneously. Grok finished first, Fable made the best website, GPT handled the deepest code.

I was wrong about Kimi K3 Just tried it in Claude Code and it is Fable 5 level for sure Far better than GPT-5.6 Sol at least at front-end It is really slow and consumes a lot of tokens but it is so good at completing its task, I like what I see here Kimi.ai

KIMI K3 is here, and it blew my mind 🤯 yes, it is expensive and very slow Took over 30 minutes, and blew an ENTIRE $20 kimi sub before it even finished the one prompt for this game. BUT OMG... the output geniuinly has fable 5 level magic built into it, this model falls between gpt 5.6 and fable 5 imo. you can play the game at kimisurfers (dot) com right now, and see what I mean. This model is too expensive to replace fable 5, BUTT it shows that the chinese open source labs are CATCHING anthropic and open ai FASTTT.

We tested Kimi K3 against Claude Fable 5 on 3D modeling and animation Asked both to recreate the Millennium Falcon from Star Wars in 1) pixel style 2) original style. Both are on Max effort. Kimi K3 took a bit longer than Fable 5 to generate, but came in ~1/3 cheaper on the 1st test, and less than half the cost on the 2nd. Interestingly, Kimi K3 handled the details at the same level as Fable 5 on the original creation, yet it wasn't at Fable's level for the pixel style. Test 1 (Pixel) Kimi K3: 1hr 11min · $14.5 Fable 5: 49min · $21 Test 2 (Original) Kimi K3: 1hr 17min · $19.3 Fable 5: 1hr 5min · $47.2

We ran a test between GPT-5.6 Sol, Kimi K3, and Gemini 3.6 Flash. One prompt. Across all three models. Using our /design command. Results (gameplay, UX, and UI): 🔹 Kimi K3 performed well across all three. 🔹 GPT-5.6 Sol is good, but it gets annoying when the ball hits the wall. 🔹 Gemini 3.6 Flash is bad (took 5–6 attempts), but it has features the others don’t, like dropping coins for power-up balls and increasing the bar length. Ranking (DX, features, and cost): 🔹 Kimi K3: 10/10 · $0.10 🔹 GPT-5.6 Sol: 9/10 · $0.52 🔹 Gemini 3.6 Flash: 6/10 · $0.45
