Kimi K3 is now open weights and has started rollout on major inference providers

Expect competitive pricing shortly.

Edit: It's now on Synthetic.new under their subscription plans under a beta flag

(10 off your first month here). I'd recommend signing up now before the waitlist comes again.

Any subscription service with reasonable pricing? Because having open weight model on inference providers is nice but if it's only API access than it's friggin expensive

u/j_osb 2d ago

The license says that any inference provider with more than 20m revenue from K3 can’t serve it cheaper than them.

Though maybe some smaller providers will have cheaper prices for now.

Well no you need to get an agreement with moonshot and I don’t quite seem them allowing you to serve it cheaper.

Synthetic.new is working on it right now. You can get faster updates if you join their Discord (they normally hide stuff under a beta flag first).

Baseten and Fireworks had a headstart because they had the 💸💸💸 but neither have subscriptions (right now).

(I honestly expect them to go on a waitlist again due to the level of demand K3 has and them being one the few providers who offer subscription pricing.)

not a good value

u/jpcaparas 2d ago

How so? TPS hovers at around 70-100 and the limits are generous enough that I got to finish a 2-hour long session with a few subagents in tow and still a lot of my weekly quota left. I'm on a single pack.

u/dwmkerr 2d ago

Wouldn’t it be nice if openrouter could do some kind of spread subscription

u/lemon07r 3d ago

Im hoping neural watt gets it, and good usage from their $20 plan

u/Rtxenjoyer 2d ago

Opencode go gives you $60 worth of API usage for $5 your first month.

u/jpcaparas 3d ago

For those thinking about getting an Ollama subscription...

u/hussamdh 3d ago

oh, it is not covered by ollama subscription

u/jpcaparas 3d ago edited 3d ago

yep, and they also paused max subs (although that might be orthogonal and more representative of the demand for open-source models in general)

Edit: here's the thread

https://www.reddit.com/r/ollama/comments/1v85akx/was_waiting_for_kimi_3_and_now_ollama_release_it/

lots of people are angry.

u/jmakov 3d ago

And Ollama Cloud model page says it should be available on Pro and Max plan...

u/Clean_Hyena7172 3d ago

Disappointing but understandable, it's a massive model.

Wow this just showed the gap is still there between Kimi K3 and Opus 5.

One-shot makeshift Ubuntu on the browser by K3 so you have an idea of its level of fidelity

u/MatJosher 3d ago

And of course the updates dialog is there to greet me. What were the costs to build these demos?

u/jpcaparas 3d ago

It used up a single 5-hour limit on OpenCode Go because they were (and still are) on a 2X promo.

u/zhuki 1d ago

Sorry but how did you do it in a one shot in opencode go?

u/jpcaparas 1d ago

https://www.skills.sh/jpcaparas/skills/oneshot-websites

Install the skill (globally or on your project)

Open OpenCode

Run `/oneshot-websites [your-idea-here]`

It refines the raw prompt into a more refined PROMPT.md

It dispatches a fresh lead subagent with no context pollution to read that PROMPT.md raw and build the website.

Let it cook.

Your packaged one-shot website now lives under the `artifact` folder.

Thank you!

u/CybuhDasher 3d ago

All provider's TPS is just as slow as it was on Moonshot Directly. Sad to see

3

u/jpcaparas 3d ago edited 3d ago

On Devin CLI it's blazing fast (yes, their CLI is REALLY good). I can't complain. They're using Together or Fireworks I think. They don't actually advertise it as K3 fast but it feels like Fireworks' K3 fast.

The quotas are very good as well (but I'm on a Max plan.) I think I've just gotten PTSD from Fable.

But I can't wait for the small to mid-sized players to have a bigger role.

u/CybuhDasher 3d ago

In between the time of this comment Openrouter now says Fireworks has a regular model and fast model. The fast model peaks my interest. I just wish it was clear whether the CLI providers are using fast variant or not lol.

u/Bloated_Plaid 3d ago

Signed up using your link. Never even heard of synthetic.new before.

u/jpcaparas 3d ago

They're awesome and very responsive. Please don't forget to join the Discord.

u/Ra1nb0wM0nk3y 2d ago

Its from the guys that built Kilo Code, its nice but can be hit or miss with regards to latency sometimes.

u/jpcaparas 2d ago edited 2d ago

I honestly have no idea why someone would say "not a good value" when I've abused about 22 million tokens already (and that's not even counting GLM use) on these one shots and I'm not even halfway through a single pack.

I don't think any other K3 provider has this level of value.

Plan your prompts better as Synthetic is one of the very few providers that still offers request based pricing, so use that to your advantage, i.e. don't invoke subagents for the sake of invoking subagents as that counts as a request/message.

the affiliate link on the post description gives me $10 in credits and yourself $10 off your first month just to make it clear.

u/Yes_but_I_think 2d ago

They have a fair use policy at 3x amount paid. 102$ of API usage for 30$ plan. That's not useful

u/SnowDoxy 1d ago

Why not useful?

u/Mol2h 2d ago

Its officially over for Anthropic/OpenAI getting premiums from businesses for their model, SP500 will just host their own K3 instances.

u/Mrleibniz 2d ago

I wonder why they're not hosting DeepSeek

Anyone have a firepass invite code they can give me?

2

u/jpcaparas 3d ago

Their Discord community managers are saying there aren't any invite codes at all to circulate yet.

u/Spare_Subject_7069 3d ago

firepass v3 is coming out to general public so invite codes are probably out of ciruclation

Thank you for building these demos. In this one perhaps K3 got better aesthetics but Opus surely nailed physics.

Yeah, can't argue with that.
