Deepest vs ChatGPT
ChatGPT is one company's models. Deepest is all of them — including OpenAI's — answering the same question at once, with the disagreements made visible instead of hidden inside a single confident answer.

A single model can't give you a second opinion
However good the model is, you're trusting one perspective.
ChatGPT: one vendor, one voice
Excellent models — but only OpenAI's, at every tier. No Claude, no Gemini, no Grok, ever. When GPT is confidently wrong, nothing in the product can tell you. And your real usage limits are dynamic and unpublished, so you find the ceiling by hitting it.
Deepest: every frontier model, cross-examined
GPT answers alongside Claude, Gemini, DeepSeek, and 300+ others — in parallel, on one subscription with published per-model prices. Where they all agree, you can trust it. Where they split, Deepest shows you the split instead of papering over it.

Frequently Asked Questions
Is Deepest a replacement for ChatGPT?
For most chat use, yes — Deepest includes OpenAI's GPT models alongside Claude, Gemini, Grok, DeepSeek, and 300+ others, so you're not giving up GPT by switching. What you gain is everything ChatGPT structurally can't do: sending one question to several frontier models at once and seeing where they agree before you trust the answer. What you'd give up: OpenAI-only extras like Sora video generation and ChatGPT's native mobile apps.
Why does it matter that ChatGPT only has OpenAI models?
Every model family has blind spots, and a single model can be confidently wrong with no way for you to know. On ChatGPT — at any price, including the $200/month tier — a second opinion means opening another product. Deepest builds the second opinion in: multiple models answer in parallel, and Synthesis, Compare, and Debate turn their agreement and disagreement into something you can act on.
How does pricing compare?
ChatGPT's paid tiers run from $8 (Go, which still shows ads) through $20 (Plus) to $100 and $200 (Pro) — all for one vendor's models, with usage limits that are dynamic and not published. Deepest starts free (200 credits, no card), Plus is $20, and every model has a fixed published credit price, with unused credits rolling over month to month. You can see exactly what your usage costs before subscribing.
Can I use GPT models on Deepest?
Yes — OpenAI's GPT models are available on Deepest alongside every other major provider, at published per-message credit prices. The point isn't GPT versus the rest; it's GPT and the rest, answering together, with the disagreements made visible.
Keep GPT. Add everyone else.
