TogetherCompute Finds Kimi K3 Matches Claude Fable 5 at 35% of Price
TogetherCompute said its DeepSWE analysis found Kimi K3 delivered the same performance as Claude Fable 5 on software engineering tasks at about 35% of the price. It said Kimi K3 also pulled ahead at higher pass@k levels.
In a separate post, Vipul Ved said the model cuts frontier AI costs by 3x and will be served natively on TogetherCompute starting July 27.

@synthwaveddAnother example output from Kimi K3 on @arena. ~Fable level. Damn.
@synthwaveddGive this a peek. Crazy, very excited
@lentils80One of the first Kimi K3 outputs for y'all, tried it on frontend 👀 First impressions is that it's VERY slow, even slower than Fable. This took 35 minutes to finish. However, this is one of the best outputs I've ever seen from this prompt,
@kimmonismusLooks like a big surprise and big release is coming today. Really really looking forward to the K3 release
@teortaxestex? I optimistically predict 53-54 on AA for K3
@lentils80🚨 Kimi K3 is already on LMArena under the stealth name "Kivine" (I know, very stealthy name)
@kimmonismusSuper excited for Kimi K3 (probably) today. 1m context, better long horizon tasks. Lets see how it performs against Opus 4.8/GPT-5.6 (Sol)!

@mtsliveSITUATION BREWING: Moonshot AI releases a video teasing their upcoming model Kimi K3.
@andrewcurran_It's happening.

@jukan05FT: KIMI TO UNVEIL K3 TONIGHT FT: KIMI’S MODEL IS EXPECTED TO HAVE 2–3 TRILLION PARAMETERS FT: KIMI K3 WILL BE AN OPEN-WEIGHT MODEL FT: KIMI K3 IS EXPECTED TO OUTPERFORM OPUS 4.8, BUT FALL SHORT OF FABLE 5
@jukan05* The reporter said it could be as early as tonight. It’s not confirmed that it will be released tonight.
@synthwavedd🚨 Per Financial Times, Moonshot intend to launch Kimi K3 as early as tonight. K3 is 2-3T total parameters - the largest Chinese model to date - while outperforming 4.8 but staying overall behind Fable in benchmarks as expected
@kimmonismusKimi k3 is being released tonight, via FT -2-3t parameters (Opus4.8 has about 1.5t) -1m context -Expected to exceed Opus 4.8 performance! The time when China was six months behind is over. History is presumably being made today. https://

@kimmonismusKimi K3 incoming. Most likely today. Btw. banger clip.
@teortaxestexOne year ago: «I know Kimi K2 has countless flaws. I have never wanted K3 more than I do right now» It'll be powerful, and it'll be useful. But most of all, I believe it'll be glorious. They have their pride. They want to have an R1-level m

@wallstengineFT reports Moonshot is set to release Kimi K3 as early as tonight. K3 is expected to be China’s largest AI model to date, with 2T-3T parameters, and will be released as an open-weight model K3 is expected to outperform Claude Opus 4.8 on

@shanumathew93Reminder that Opus 4.8 came out at thee end of May. So frontier leadership went from 6+ months to 1-1.5 months. Unclear how much of this is because of wide distillation and how far internal models are at American labs but the direction is
