2. Features What it does

Feature	What it does
Model switcher	~130 open-weight models (Llama 4 / Qwen3 / Kimi K3 / GLM-4.6 / Command A / DeepSeek-R1 / Olmo 3), mid-conversation switch — Catalog rotates with Hub releases
Omni router	Auto-picks model per turn, can call image/tool sub-routes — Default on new chats
Web search	Exa-powered, wired as default MCP server, real-time citation pull — Off by default in some presets
Multimodal	Image/PDF/DOC upload for analysis (no native TTS voice mode) — Image generation via ZeroGPU tool, not a base modality
Image gen	Omni → Z-Image-Turbo on ZeroGPU, ~3 imgs/day Free effective — Free ZeroGPU: 5 GPU-min/day + 3 runs/day
Tools / MCP	Exa search MCP, image-gen MCP, batch CSV mode, custom webhook “Actions” — No native connector store like ChatGPT GPTs
Custom assistants	System-prompt + tool config (library sharing disabled Aug 2026) — Local-only/private assistants still work
Self-host	Chat UI repo on GitHub, Docker, BYO model endpoint — Same weights as Hub
Privacy	Logged-in + “Disable data sharing” = no training; guest chats may feed research — Enterprise instances zero-retention

Plan	Price / mo	Key limits & who it fits
HuggingChat (Free)	$0	Full model switcher, Omni, Exa search, uploads, $0.10 Inference Providers credit/mo, ZeroGPU 5 GPU-min/day (≈3 img)
HF Pro	$9/mo	Not required for chat; raises Inference Providers credit to $2/mo, ZeroGPU 40 min/day, priority queue, private storage 1TB
HF Team	$20/seat	$2/seat infer credit, ZeroGPU 40 min, org billing caps
HF Enterprise	from $50/seat	SSO/SCIM/audit, ZeroGPU 60 min, private Chat UI deploy, zero-retention
Inference Providers overage	PAYG, HF passthrough no markup	After $0.10/$2 credit gone, text stops unless you add card; image gen stalls on ZeroGPU quota
Inference Endpoints	$0.50–$80/hr GPU	Only if you wire HuggingChat-style UI to a dedicated endpoint

Source	Rating	What it says
ToolChase	“Completely free access to frontier open-source models; Omni router + Exa + MCP; UX trails ChatGPT, custom assistants disabled Aug 2026”
Softabase	7.6/10 — “free with no meaningful usage walls, but bare-bones: no canvas/plugins/voice, quality variance across models, peak-hour slowdowns”
AI Tier List	Tier B vs ChatGPT Tier S — wins on open/transparent/price, loses on polish/agent/reliability
BuildFastWithAI	4.1/5 — “primary free option for evaluating open weights before self-host; trailing GPT-4o-class on complex instruction following”

✔ Suitable	✘ Not suitable
