Looking for an Abacus ChatLLM alternative? Routing is not the same as checking
ChatLLM Teams is honest about what it is: one AI assistant with access to 100+ top models, routing to the best one for the task, at $10 a month — remarkable breadth for the price. But notice the shape: however many models sit behind the router, each answer still comes from one of them. Routing optimises which single model speaks; it does not tell you whether that model is right. For everyday work that trade is fine. For an answer you have to stand behind, one well-chosen model is still one model.
Decidi is built for the moment that trade stops being fine. Instead of routing to one best model, it convenes rivals — GPT, Claude, Gemini and Grok — on the same question at once, makes them debate across structured rounds with 92 expert personas and a Devil's Advocate, and surfaces exactly where they disagree. A moderator synthesises one verdict, a Final QA audit from a separate lab reviews it against known failure modes, and the result arrives as a downloadable deliverable. Entry is free and anonymous — chat with no account, every reply stamped with the model that wrote it — and your first full Multi-Agent run is included with a free signup. Plans are priced in stated runs: Plus at $19/month includes 16 a month.
- Rival labs answer the same question at once — instead of a router choosing one voice
- Disagreement between models is surfaced explicitly — the strongest error signal there is
- A Devil's Advocate and 92 expert personas pressure-test the work by design
- A Final QA audit from a separate lab reviews every verdict before it is final
- A downloadable, sign-off-ready deliverable — not an assistant thread
- Free anonymous chat to start, first full run included at signup, then Plus at $19/month with 16 stated runs a month
Part of: How Decidi works
One audited verdict from four rival labs — the agreements, the splits, what to verify — delivered as a document you can sign off.
Common questions
What should I look for in a ChatLLM alternative?
Start with what the many models are actually doing. Behind ChatLLM's assistant, routing selects a strong model for each task — breadth in service of convenience. If that is what you need, it is priced extremely well. If what you need is confidence — knowing whether the answer would survive a rival model's attack — look for a tool where several independent models answer the same question, where their disagreement is shown rather than smoothed over, and where something independent audits the result. That is the shape Decidi is built in.
How is Decidi different from Abacus ChatLLM?
ChatLLM is one assistant with many models behind it; per its own description, it routes to the best model for the task — so each answer is still a single model's answer, chosen well. Decidi runs the models against each other: four rival labs debate your question in structured rounds, a moderator synthesises the verdict, and a Final QA audit from a lab that did not chair the debate reviews it before you see it. ChatLLM optimises who answers; Decidi tests whether the answer holds.
Is Decidi more expensive than ChatLLM?
They price different things. ChatLLM's published price is $10/month for the assistant with 100+ models behind it. Decidi's chat is free — no account, no card — your first full Multi-Agent run is included with a free signup, and Plus at $19/month includes 16 full runs a month, each one a complete debate, separate-lab audit and downloadable deliverable. If you never need work checked, ChatLLM is cheaper. If you do, a checked verdict is what the run price buys.
Can I see Decidi work before paying anything?
Yes. Chat free with no account — pick GPT, Claude, Gemini or Grok as your base model, with every reply stamped with the model that wrote it — and challenge any reply with one tap to have a rival lab's model audit it. A free signup includes your first full Multi-Agent run, so the complete debate-audit-deliverable loop is visible before any plan.
