Kimi K3 Now Available via Telnyx Inference API
Posted by fionaattelnyx 13 hours ago
Moonshot AI released open weights for Kimi K3 today and it's live on Telnyx Inference. The architecture and Moonshot's own benchmarks are in their technical blog. This post is about running it on Telnyx.
What we are adding: K3 is now available via the Telnyx Inference API, hosted on GPUs that we own and operate.
This matters due to the size of this model. A 2.8T model needs dedicated infra to serve well. Because we own and operate the GPUs, we can contorl throughput. with no inter-provider hops and no cloud tenant, latency is minimized. We have GPUs in each of the US, EU, APAC, and MENA. Inference runs in the region you pick, with zero data retention. We do not store prompts or completions after the response returns. Because we own the infra, the per-token price reflects the cost of running the model, not the cost of renting someone else's plus their margin.
We have not benchmarked K3 ourselves yet. Moonshot's own numbers and early third-party evaluations put it at frontier level for coding and agentic work, trailing only Claude Fable 5 and GPT 5.6 Sol on aggregate. Full breakdown in their blog.
Pricing on Telnyx: $2.70/1M input tokens, $13.50/1M output tokens, $0.27/1M cached input tokens. Prompt caching enabled by default. Served via an OpenAI-compatible endpoint so you can test easily.

Why is this provider specifically on the front page?
Also why is this not available over openrouter?

Or does openrouter have like a specific contract you have to sign with them and requirements or smth? https://openrouter.ai/moonshotai/kimi-k3#providers

€2.693/M input €13.464/M output Surprisingly, cache is not mentioned
Upd: Tensorix joined the fray, with the same prices, with cache at €0.673/M read

But I don't feel like providing inference is a professional move, it feels like out of scope for a telephony IaaS company. Feels like a FOMO moment where a reputation of years is crashed in a couple of weekends of being drawn into a fad.
And the fact that it's a chinese model doesn't quite help? I guess it's on brand with the 'cheap' pay as you go brand telnyx might already be associated to.
But more so it reads like Telnyx is trying to 'jump' into the trend of the 'open weights' discussion to compete with closed source incumbents. But we are at the tail end of the boom, anti ai sentiment is ever growing, customers now despise AI, especially in support channels, which is presumably the hook that Telnyx would have into 'AI'(LLMs). At this stage any company or individual that tries to join into the buzzword fueled cycle will pay the full fixed cost reputational price, but only reap the leftover hay from when the sun shone.
AI(LLM) on support channels is essentially a decapitalization of a company/brand, the company has a reputation that customers value, and might be worth good money in the market, and by implementing AI (LLMs) on support, a lot of costs can be cut, while the brand loses value, not sustainable. And by Telnyx (or any B2B company)asking their clients to participate in this decapitalization move, they essentially gamble their reputation as well, albeit with better odds as shovel sellers.

OVH same thing. Tried to buy a VPS from them some years back and they said no VPS unless I provided ID. Would not refund me. Tried to dispute but my bank just gave me a credit instead.

Such use would be incompatible because it would lure in fraud, which would ruin the reputation of shared comms resources like ip blocks, phone number blocks, etc..
If you are doing real business, you are providing KYC as a daily matter in procurement, thereby protecting consumers from Sybil scum.

No? Firstly you can't do a Sybil attack when each identity costs actual resources, and secondly you can still have lots of phone numbers, they just know who each one belongs to.

since you asserted something false and bizarre, how about telling us what is your markup?Comment by alexeldeib 9 hours ago

We estimate that the true blended price per million tokens for running Opus 4.7 on agentic tasks at $0.99 despite the sticker price being $5/$25 per MTok.
https://newsletter.semianalysis.com/p/ai-value-capture-the-s...according to Semianalysis those prices would be far above actual costs.

> Agentic workloads have extremely high input-to-output ratios (our Claude Code usage has a ratio of about 300:1) and high cache hit rates (90%+). Because cached input tokens only cost $0.50/MTok, most of the tokens end up in the cheapest tier.
90% cache hit input blend: 0.9 * $0.5 + 0.1 * $5 = $0.95 per MTok.
300:1 input/output blend: (300 * $0.95 + $25) / 301 = $1.03 per MTok.
They don't say exact cache hit rate they calculated for ("90%+"), so close enough.

I largely agree things are overpriced, I just don't think that article is the right basis for saying it about this one.

Not the **literal** cost
