# Introducing Open-weight models

Run Kimi, Qwen, DeepSeek, and GLM in chat, at a fraction of US lab prices, served on US infrastructure.

## The problem

If you run SEO yourself, or you are the lean growth person at a B2B SaaS, the expensive US lab models chew through credits. You start saving Claude Opus, Claude Fable, and GPT-5.6 Sol for "the real work" and you run fewer briefs, fewer competitor checks, and fewer draft loops than the backlog needs.

That is a budget problem, not a skill problem. You already know what to do. You cannot afford flagship prices on every turn of the agent.

Open-weight models from Moonshot, Alibaba, DeepSeek, and Z.AI have closed most of that quality gap on public leaderboards. The leftover objection has been hosting. Nobody wants to paste a brand brief into an API they cannot explain to legal.

## What's new

Those models are now in Zerply chat, in the same picker as Claude, GPT, and Gemini. Open **Zerply Agent**, click the model name next to the send button, and search for Kimi, Qwen, DeepSeek, GLM, or Grok.

Open-weight means the model is not locked inside one US lab. US providers can host it, which is how Kimi, Qwen, DeepSeek, and GLM show up in Zerply without sending your prompts to a China-hosted API. You still pay in the same AI Agent credits.

What is in the picker:

- **Kimi K3** (Moonshot)
- **Qwen 3.8 Max**, **Qwen 3.7 Plus**, and **Qwen 3.7 Flash** (Alibaba)
- **DeepSeek V4 Pro**
- **GLM 5.3** and **GLM 5.2** (Z.AI). 5.3 is the latest, same price as 5.2, stronger on long agent work
- **Grok 4.6** (xAI)

[Claude Opus 5](https://zerply.ai/resources/blog/claude-opus-5-for-marketers) is already in that list. Keep it for the jobs that earn flagship spend.

On [Artificial Analysis's Intelligence Index](https://artificialanalysis.ai/articles/kimi-k3-achieves-3-in-the-artificial-analysis-intelligence-index-comparable-to-opus-4-8-and-gpt-5-5), Kimi K3 scores 57 with max reasoning. Claude Fable 5 is 60. GPT-5.6 Sol is 59. That is a few points, not a generation. DeepSeek V4 Pro, GLM, and the Qwen 3.7 line cost a fraction of Opus and Sol, so volume work does not have to live on the flagship.

## What you can do now

- **Spend credits on more work:** Run cluster briefs, competitor checks, and first drafts on DeepSeek, GLM, Qwen, or Grok, and keep Opus or Fable for the jobs that earn the extra spend.
- **Stay on US infrastructure:** Use the Chinese labs' models without sending the brief to a China-hosted API.
- **Switch without leaving chat:** The same picker is on new blog and landing page drafts, so the model follows the job.
