In our evaluations, Kimi K3 delivers frontier-level performance. Among the models tested, its overall intelligence ranks second only to Claude Fable 5 and GPT-5.6 Sol. For the complete benchmark results, see our tech blog. The full model weights of Kimi K3 will be released in the coming days. More details on the architecture, training, and evaluation will be published together with the Kimi K3 technical report.

K3 pushes the boundary of end-to-end knowledge work. On the GDPval-AA v2 leaderboard, Kimi K3 scores 1687. The benchmark evaluates AI models on real-world tasks across 44 occupations and 9 major industries; Kimi K3 ranks behind only Claude Fable 5 Max and GPT-5.6 Sol Max, and ahead of Claude Opus 4.8 Max at 1600.

On AA-Briefcase, Kimi K3 scores 1527, ranking second among all models — behind only Claude Fable 5 Max and ahead of GPT-5.6 Sol Max (1495). AA-Briefcase is a private agentic knowledge-work benchmark developed by Artificial Analysis to evaluate frontier agentic capability in long-horizon knowledge work.

Really good benchmark score it seems. Maybe another DeepSeek moment right here.

Gemini 3.5 Flash 2 months ago

Seems like the only good thing about 3.5 Flash is its speed. Not cost-competitive or benchmark-leading by any means.

Not disagreeing with your argument, but:

If you want a good dense model, use qwen3.6 27B instead, speed will be up, and if you don't take my word for it being smarter, take openrouter's prices of it against the bigger, slower and less memory-efficient gemma do the talking.

Don't know if this is the correct read. I think those providers are simply taking cue from Alibaba's first-party pricing for the 27B Dense. It's kinda overpriced imo. Perhaps it can be explained by how 'reasoning-inefficient' (relative to frontier models or even Gemma) the Qwen models are and longer sequence lengths are expensive to serve.

You cannot run these models at 8-bit on a 32GB card because you need space for context

You probably can actually. Not saying that it would be ideal but it can fit entirely in VRAM (if you make sure to quantize the attention layers). KV cache quantization and not loading the vision tower would help quite a bit. Not ideal for long context, but it should be very much possible.

I addressed the lossless claim in another reply but I guess it really depends on what the model is used for. For my usecases, it's nearly lossless I'd say.

Yeah, figure the 'nearly lossless' claim is the most controversial thing. But in my defense, ~97% recovery in benchmarks is what I consider 'nearly lossless'. When quantized with calibration data for a specialized domain, the difference in my internal benchmark is pretty much indistinguishable. But for agentic work, 4-bit quants can indeed fall a bit short in long-context usecase, especially if you quantize the attention layers.

As this is a dense model and it's pretty sizable, 4-bit quantization can be nearly lossless. With that, you can run this on a 3090/4090/5090. You can probably even go FP8 with 5090 (though there will be tradeoffs). Probably ~70 tok/s on a 5090 and roughly half that on a 4090/3090. With speculative decoding, you can get even faster (2-3x I'd say). Pretty amazing what you can get locally.

Btw as an aside, we didn’t announce on Friday because we respected the IMO Board's original request that all AI labs share their results only after the official results had been verified by independent experts & the students had rightly received the acclamation they deserved

We've now been given permission to share our results and are pleased to have been part of the inaugural cohort to have our model results officially graded and certified by IMO coordinators and experts, receiving the first official gold-level performance grading for an AI system!

Was OpenAI simply not coordinating with the IMO Board then?

How I Use Kagi 1 year ago

Maybe not a popular sentiment here on HN but I cancelled my Kagi subscription (9+ months) just recently. Increasingly, most of my queries/search have been through LLMs and Google search is just fine (and even better for restaurants, places, and the like). I don't think the improved search experience is worth the subscription anymore.

GCP Outage 1 year ago

Super duper frustrating having the status page being green. Why can't Google do this properly?

The bottleneck then becomes how to self-host the finetuned model in a way that's cost-effective and scalable

It's not actually that expensive and hard. For narrow usecases, you can produce 4-bit quantized fine-tunes that perform as well as the full model. Hosting the 4-bit quantized version can be done on relatively low cost. You can use A40 or RTX 3090 on Runpod for ~$300/month.

GPT-4.5 1 year ago

Because of this, we’re evaluating whether to continue serving it in the API long-term as we balance supporting current capabilities with building future models.

Seems like it's not going to be deployed for long.

$75.00 / 1M tokens for input

$150.00 / 1M tokens for output

That's crazy prices.

I do actually wonder if it's more efficient to use something like MessagePack instead of using JSON. It's a lot of strings so it may not matter too much I guess.

While the math seems intimidating, it does not look all too different from SPIN and previous researches. Pretty surprising how effective this is though. The costs here seems to be way higher too (with all the GPT4 calls).

We also do a brief cost analysis associated with the scaled-up experiment on 600k training inputs. The major line items are the cost of sampling outputs, annotating them with GPT-4 to construct training pairs, and then training the next iteration against those pairs. For _each_ of the six iterations:

1. Sampling: it took about 18-24 hours to inference 5 outputs for all 100k examples on 10 8xA100 80GB pods, depending on the average length, costing about $6,000 based on spot pricing.

2. Annotation: the average number of prompt tokens sent to GPT-4 for annotation across iterations was about 450M, with an average of about 60M completion tokens, amounting to about $34,000 based on the version of the endpoint we were using.

3. Training: ironically, training was the cheapest step, taking only 12-24 hours on two 8xA100 80GB nodes

Well, there was a tweet by one of the Bloomberg's journalist saying that Musk tried to manouver himself to be the replacement CEO but got rebuffed by the board. Paraphrasing this since the tweet seems to be deleted (?), so take of it what you will.
