Hydra and T3 Chat
T3 Chat is a fast chat app with models from several companies. Here is what each offers.
| Hydra | T3 Chat | |
|---|---|---|
| Models | Claude, GPT, Gemini, Grok, DeepSeek, Mistral, Perplexity and more through OpenRouter (the ones connected to the site, plus any you add with your own key) | OpenAI, Claude, Gemini, plus DeepSeek, Qwen, Llama, Grok, Kimi and others 1 |
| Several models answer at once | Fusion merges several models' answers and checks disputed claims; Compare shows them side by side | Not that we found |
| Use your own API keys | Yes, free: the AI companies bill you directly | Yes 2 |
| Web search | Yes, with numbered citations; Research writes a cited report | Yes, a per-chat switch 2 |
| Images | Yes, and photo editing and video (when the site has Higgsfield connected) | Yes, with OpenAI and Google image models 1 |
| Usage limits | 10 free messages, then a monthly plan with a usage allowance | A usage meter: a base allowance that refills every 4 hours and an extra one that refills monthly 2 |
| Paid plan | Hydra Plus, £13.99 a month | Not shown on the pages we could read (reported elsewhere as $8 a month) |
T3 Chat's pricing page couldn't be read when we checked. Plans, prices and limits change often: check T3 Chat's own pages for today's. We don't claim either is better at answering; that depends on the question and the models used.
