Um, based on the public information, I think it works roughly like this: * * * **Yes — image generation currently works in HuggingChat/Omni.** The simplest route is to leave **Omni** selected and ask for the image directly, for example: ```plaintext Generate an image of a small red robot reading a book in a watercolor style. ``` This is also consistent with the current [HuggingChat home page](https://huggingface.co/chat/), which includes **“Generate an image.”** as one of its starter prompts. There is also a useful [public HuggingChat conversation showing the current behavior](https://huggingface.co/chat/conversation/CsZVA3k?leafId=0ebe41df-91af-4770-b08d-fe963fa71d34): the user asks for an image, Omni takes an `agentic` route, and the conversation shows: ```plaintext Called tool gr1_z_image_turbo_generate ``` So, at least in the currently observable implementation, you do not need to switch the whole conversation to an image model manually. Omni can call an image-generation tool/Space when the request calls for one. ### What about the limits? For a **Free account** , my best reading of the currently public information is: > **On the currently observed ZeroGPU image-generation route, the practical limit is probably around 3 generated images per day.** There is an important caveat to that wording: I do **not** see an official HuggingChat page saying “Free = exactly 3 images/day.” Rather, the public information currently fits together like this: - The official [ZeroGPU documentation](https://huggingface.co/docs/hub/spaces-zerogpu) says a Free account gets **5 GPU-minutes/day**. - In an April 2026 HF Forum discussion about Free ZeroGPU limits, `hysts` explained that there is also a **request-based limit in addition to the time-based quota** , and then stated that [the current request-based limit is three times per day](https://discuss.huggingface.co/t/free-account-zerogpu-quota-issue/175180/9). - The image generator used in the public HuggingChat example above was Z-Image-Turbo. Its [current Space implementation](https://huggingface.co/spaces/mcp-tools/Z-Image-Turbo/blob/main/app.py) is running on ZeroGPU and produces one image per generation call. So the inference is roughly: ```plaintext Free ZeroGPU account | +-- 5 GPU-min/day | +-- 3 ZeroGPU runs/day | +-- current observed image tool: 1 run -> 1 image | v roughly 3 images/day ``` I would treat that as the **current effective behavior** , rather than a permanent “3-image HuggingChat plan.” The tool being selected, its implementation, and HF’s quota policy can all change. One other thing that makes this confusing: **the normal HuggingChat/Omni allowance and the ZeroGPU image-generation allowance are not the same quota.** > **Why HuggingChat's limits are a little confusing** > > There are at least two separate resource/accounting systems involved here. > > | Layer | What is limited | Current public information | > | --- | --- | --- | > | HuggingChat / Omni model inference | Inference Providers usage | Monthly monetary credits | > | ZeroGPU image-generation tool | GPU time | Free: 5 GPU-min/day | > | Free ZeroGPU additionally | Number of runs | 3 runs/day, according to the HF Forum answer above | > > The first line is easy to confuse with the other two. > > When HuggingChat Omni was introduced, HF described it as a router over models served through [Hugging Face Inference Providers](https://huggingface.co/spaces/huggingchat/chat-ui/discussions/764). Omni examines the request and chooses a route/model rather than necessarily using the same model for every message. > > The current [Inference Providers pricing documentation](https://huggingface.co/docs/inference-providers/pricing) lists the included monthly credits as: > > | Account | Included Inference Providers credits | > | --- | --- | > | Free | $0.10/month, subject to change | > | PRO | $2.00/month | > | Team / Enterprise | $2.00 per seat | > > Those are **monetary inference credits** , not a fixed “N messages per day” allowance. > > That distinction matters because different routed models/providers can have different costs, and request size also matters. So two HuggingChat messages are not necessarily equivalent in cost. > > By contrast, ZeroGPU has its own usage system. The current [ZeroGPU documentation](https://huggingface.co/docs/hub/spaces-zerogpu) lists: > > | Account | Included daily ZeroGPU quota | > | --- | --- | > | Unauthenticated | 2 min | > | Free | 5 min | > | PRO | 40 min | > | Team | 40 min | > | Enterprise | 60 min | > > The docs also say that this included ZeroGPU quota resets **exactly 24 hours after your first GPU usage** — it is not simply a midnight/calendar-day reset. > > So if you see people discussing “HuggingChat limits,” it is worth checking which limit they mean: > > ```plaintext > normal Omni/model inference > -> Inference Providers credits > > image-generation Space execution > -> ZeroGPU quota / ZeroGPU run limit > > ``` > > There have already been [Forum discussions where these two systems were confused](https://discuss.huggingface.co/t/problem-with-hugging-chat/178021), which is understandable because both can ultimately look like “HuggingChat stopped letting me do something.” > **What seems to happen under the hood** > > The current public evidence suggests a path approximately like this: > > ```plaintext > You > | > | "Generate an image of ..." > v > HuggingChat Omni > | > | chooses an agent/tool route > v > image-generation MCP tool / Space > | > v > ZeroGPU execution > | > v > generated image > > ``` > > The useful part here is that the **conversation model does not necessarily have to be the image generator itself**. > > For example, in [this public HuggingChat conversation](https://huggingface.co/chat/conversation/CsZVA3k?leafId=0ebe41df-91af-4770-b08d-fe963fa71d34), the response is marked: > > ```plaintext > agentic with Kimi-K2-Instruct-0905 via groq > > ``` > > while the same conversation separately shows: > > ```plaintext > Called tool gr1_z_image_turbo_generate > > ``` > > That is a fairly direct example of a text/chat model orchestrating a separate image-generation tool. > > This also matches HF’s general MCP architecture. The official [Spaces as MCP servers documentation](https://huggingface.co/docs/hub/spaces-mcp-servers) explains that compatible Spaces can be exposed as tools, and specifically notes that when a **ZeroGPU Space** is called as a tool, **the caller’s ZeroGPU quota is used**. > > The currently observed Z-Image-Turbo Space is a concrete example.

That does **not** mean Safari is the cause of every missing image; it is just a useful example showing why “I cannot see the image” and “the image generator failed” should not automatically be treated as identical observations. > > ### If no tool is called at all > > I would first retry with **Omni** and an explicit generation request such as: > > ```plaintext > Generate an image of ... > > ``` > > rather than trying to manually force tool support. > > For hosted HuggingChat specifically, a [May 2026 chat-ui change](https://github.com/huggingface/chat-ui/pull/2251) made the router/provider the source of truth for tool-calling and multimodal capabilities; those capability toggles are read-only on HuggingChat.

It may describe the initial Omni relaunch rather than the current service. ### Short version - **How:** leave **Omni** selected and simply ask it to generate an image. - **Free image limit:** with the currently observable ZeroGPU route, **roughly 3 images/day** is a reasonable estimate, because Free currently has a reported **3 ZeroGPU runs/day** cap and the observed generator returns one image per run. - **But:** that is an _effective current limit_, not an official permanent “3 images/day” HuggingChat specification. - **Also:** normal HuggingChat/Omni inference uses **Inference Providers monthly credits** , which are separate from the ZeroGPU limits used by the image-generation tool. --- _[View the full topic](https://discuss.huggingface.co/t/how-do-i-generate-images-through-huggingfacechat/178589)._
