Tencent Hy4 is a full 770B vision and Computer-Use model, but it outputs text and actions, not posts. Kompozy generates and publishes finished content.
If you searched "Tencent Hy4 alternative," start with what the full Hy4 actually is, because it's a genuinely capable release and this page won't pretend otherwise. Hy4 is Tencent Hunyuan's full next-generation mixture-of-experts model — the series puts it at 770 billion total parameters — released November 4, 2026, now with two abilities new to the line: native visual understanding (reading charts, screens, and image detail) and Computer Use (operating software through graphical and command-line interfaces). It reasons, it sees, and it can drive a computer. For engineering, analysis, and agentic automation, it's a strong pick.
I run Kompozy, and the honest framing is that Kompozy is not a large language model and doesn't try to be one — it doesn't reason over a codebase, read a dashboard, or operate your computer. The "Computer Use" headline tempts a specific misread: that a model which can drive software could therefore run your content operation. It can't, and it's worth being precise about why. Hy4 operating a computer means executing engineering and tool tasks — a Blender script, a command-line job, a cross-app workflow. It does not mean generating a branded carousel, narrating a short on camera in your voice, or publishing a reviewed post to eight platforms on a schedule. Those aren't "computer tasks" it happens to skip; they're a different product.
So most people typing "Hy4 alternative" split into two groups. The first genuinely needs a reasoning, vision, or agentic model, in which case Hy4 (or a peer like GLM-5.3 or DeepSeek V4 Pro) is the right answer. The second wanted finished content and found that Hy4 hands back text and actions — no video, no carousel, no captions, no schedule, no post. That second group is who this page is for, and below is where each tool actually fits.
Hy4 is a multimodal large language model from Tencent's Hunyuan team, released November 4, 2026. It uses a mixture-of-experts architecture (the series is described at 770B total parameters) and adds, over the August Hy4 preview, native visual understanding and Computer Use — reading images and charts, and operating software through graphical and command-line interfaces, with specialized training on tools like Blender and CAD that Tencent says improves its ability to plan and carry out long, complex tasks. Tencent positioned it as an open-source model and said weights plus a System Card would follow soon; at launch access was via API through Tencent Cloud TokenHub and OpenRouter and inside Tencent products like WorkBuddy, CodeBuddy, Yuanbao, and ima, at reported pricing of about $0.90 per million input tokens and $2.70 per million output tokens. What it produces is text and actions — it generates no images, video, or audio, applies no brand voice, and does not schedule or publish anything.
You'd look past Hy4 the moment your goal shifts from "understand, draft, or automate this" to "publish content." Vision lets it read a chart and Computer Use lets it run a script, but neither produces a feed-ready asset: there's still no hook, no captions for muted autoplay, no vertical crop, no branded visual, and no path to a platform. And Hy4 is tuned for engineering, so its English short-form voice is unproven and its drafts read like model output. Turning any of it into content means bolting on an infographic and carousel designer, an avatar-video tool, a caption and clipping layer, a brand-voice governor, and a scheduler. There are practical caveats too: the vision, agentic, and benchmark numbers are Tencent's own and await independent verification, and the full model's open weights were still pending at launch, so self-hosting isn't yet an option the way it is for the preview. Kompozy is the alternative when you want that entire downstream — finished, captioned, on-brand content across formats and platforms — handled in one place, without assembling a stack around a reasoning model.
| Feature | Tencent Hy4 | Kompozy | Note |
|---|---|---|---|
| Coding & agentic engineering | Yes | No | Hy4's core purpose; Kompozy is not a coding or agent model. |
| Computer Use (operate software) | Yes | No | Hy4 drives GUI and command-line tasks; Kompozy is a content engine, not a desktop agent. |
| Native visual understanding | Yes | No | Hy4 reads charts, screens, and image detail as input; Kompozy consumes a source, not a screen. |
| Long-context reasoning | Yes | No | Hy4 ingests whole codebases and transcripts; Kompozy is a generate-and-publish engine, not a raw model. |
| Open weights / self-hostable | Pending (promised) | No | Hy4's full-model weights were not released at launch; Kompozy is a hosted product. |
| Persona / avatar explainer video | No | Yes | Kompozy makes HeyGen/Persona talking-head video; Hy4 outputs text and actions only. |
| Carousels, infographics, quote graphics | No | Yes | Kompozy generates brand-exact carousels and infographics via HyperFrames plus quote cards; Hy4 generates no media. |
| Blog & newsletter generation | Partial (raw text) | Yes | Hy4 can draft prose; Kompozy produces finished, voice-governed Blog Articles and Email Newsletters. |
| Feed-styled captions & clipping | No | Yes | Kompozy burns branded captions and cuts vertical shorts; Hy4 has no media output. |
| Brand voice governance | No | Yes | A Persona Brief and banned-word filters govern every Kompozy output; raw model text has no voice layer. |
| Scheduling & multi-platform publishing | No | Yes | Kompozy schedules and publishes across the whole surface; Hy4 publishes nothing. |
| Cheap, high-volume raw text | Yes | No | Hy4's low per-token pricing is a real advantage for bulk drafting; Kompozy is priced by finished output. |
| Tier | Tencent Hy4 plan | Tencent Hy4 price | Kompozy plan | Kompozy price |

Here's the clean way to see the choice. Hy4 is a reasoning, vision, and Computer-Use model; Kompozy is a content engine. If you specifically need to code, automate software, or read and analyze a visual source, use Hy4 — Kompozy won't do that, and this page won't pretend it does. The two aren't mutually exclusive: a smart workflow uses Hy4 (or any model) to read, draft, and analyze at the front, then hands the result to Kompozy to become content.
Because the moment the analysis exists, the real work is the rest of the recipe — a branded visual for the insight, a face on the idea, one consistent voice, and reliable distribution. Kompozy is built to be that recipe: from a prompt or a source it generates across 18 formats — Persona and HeyGen avatar video, Clipped Shorts, Carousels and infographics via HyperFrames, Photo Posts, Quote Graphics, Blog Articles, Email Newsletters, and Text Posts — every piece held to your Persona Brief, then reframed per platform and scheduled and published across eight social platforms plus blog and email through Autopilot and a review pipeline. Let Hy4 do the reasoning if you love it, and let Kompozy make and ship everything around it.
Only for part of the job. Hy4 is a reasoning, vision, and Computer-Use model that outputs text and actions; Kompozy doesn't reason over code, read a screen, or operate your computer. Kompozy is the alternative when your goal is finished, published content — captioned video, carousels, infographics, a blog, a newsletter — generated in one brand voice and distributed across platforms, rather than raw model output.
No. Hy4's Computer Use executes software and engineering tasks through graphical and command-line interfaces — scripts, tool automation, cross-app workflows. It does not generate branded media, govern a brand voice, or publish reviewed posts to platforms on a schedule. That end-to-end content workflow is what Kompozy does.
Yes, and it's the strongest setup. Use Hy4's vision and long context to read a chart, deck, or dense source and return a brief, then drop that text into Kompozy as a source. Kompozy rewrites it under your Persona Brief, fans it into video, carousels, infographics, a blog, and a newsletter, and schedules the batch across platforms.
Hy4 API access is reported at about $0.90 per million input tokens and $2.70 per million output tokens, while Kompozy is credit-based from $199/mo (5,500 credits). They meter different things — raw reasoning versus generated-and-published content — so compare by the outcome you need, not the sticker.
No. Hy4 outputs text and actions and has no publishing capability. Kompozy publishes to eight social platforms — Instagram, Facebook, TikTok, YouTube, LinkedIn, X, Pinterest, and Threads — plus blog and email, with scheduling, a per-post review, and autopilot.
