A maintainer reported that some DeepSeek Flash requests were routed to a provider that rejected the configured output-token limit. The temporary configuration change was merged that day, with successful tests reported for the adjusted setting.\n\n**It might be related, but it doesn’t establish what happened to your two failing projects.** We don’t yet know whether you’re using HuggingChat Omni, which models are involved, or whether the error is still happening. That same message can appear for different reasons, including a failed inference request, an issue with a particular conversation, or a problem in another application.\n\n**The lowest-effort route I’d suggest:**\n\nI wouldn’t top up again, delete the original work, reset a Space, or change a spending limit just to see whether the message goes away. The fact that **two work and two don’t** is already a useful starting point.\n\nThe optional sections below give the possible branches and sources in more detail; none requires you to carry out every check.\n\nA small, safe comparison if the problem continues\nThe two most helpful details would be whether **the error still occurs** and what you mean by the four **“projects.”** If a model name or safely redacted error code is already available, that may narrow it further, but there’s no need for another payment or a lengthy debugging session just to reply.", "url": "https://wpnews.pro/news/the-chat-is-not-working", "canonical_source": "https://discuss.huggingface.co/t/the-chat-is-not-working/191241#post_2", "published_at": "2026-10-31 00:24:53+00:00", "updated_at": "2026-10-31 00:47:18.125315+00:00", "lang": "en", "topics": ["ai-tools", "large-language-models", "ai-products"], "entities": ["Hugging Face", "HuggingChat Omni", "DeepSeek Flash", "chat-ui"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/the-chat-is-not-working", "markdown": "https://wpnews.pro/news/the-chat-is-not-working.md", "text": "https://wpnews.pro/news/the-chat-is-not-working.txt", "jsonld": "https://wpnews.pro/news/the-chat-is-not-working.jsonld"}}
