The hidden model routing, the reasoning effort you cannot see, or a subscription that quietly stopped being the product you bought. Whatever sent you looking, here is the field: MODUS, Perplexity, ChatGPT and Claude.
Full disclosure
We build MODUS, which we have placed first. Judge the ranking accordingly. Every price and model list on this page comes from each product's own published pricing as of July 2026, so you can check all of it.
Why people go looking
Almost everyone searching for an alternative is running into one of three walls.
- You cannot see which model answered, or at what effort. Perplexity Pro routes between Sonar, GPT-5.2, Claude Sonnet 4.6 and Gemini 3.1 Pro without telling you which one you got. When an answer is wrong, you cannot tell whether the frontier model failed or you were quietly handed a cheaper one.
- The frontier models are behind the expensive tier. Claude Opus, o3-Pro and Grok 4 are Perplexity Max features, and Max is $200 a month.
- One model, one opinion. ChatGPT and Claude each answer from a single lab. When that lab is confidently wrong, nothing in the product tells you.
1. MODUS — every frontier model, side by side
MODUS runs the current frontier model from every major lab under one subscription, names the exact model on every answer, and can run the same question through all of them at once.
| Plan | Price | Models |
|---|---|---|
| MODUS | $24/mo · $240/yr | Llama 3.3, DeepSeek V3.1, GPT-5.6 Terra, Claude Sonnet 5, Gemini 3.5 Flash |
| PILOT | $59/mo · $588/yr | Adds Claude Opus 4.8, Claude Fable 5, GPT-5.6 Sol, Gemini 3.1 Pro, Llama 4 Maverick |
A newer generation than anyone else on this list
This is the part worth checking against the tables further down. MODUS serves GPT-5.6 where Perplexity serves GPT-5.2. Claude Sonnet 5 and Opus 4.8 where Perplexity serves Sonnet 4.6 and Opus 4.5. Plus Claude Fable 5, which none of the others carry at any price.
Ten models on one question, for $59
Compare mode runs the same prompt across up to ten models simultaneously and shows the answers side by side with a verdict on which one served you best. Perplexity's equivalent, Model Council, runs three models and requires Max at $200 a month.
That is more than three times the models for less than a third of the price.
The exact model, named, every time
Every MODUS answer carries the name of the model that produced it. If a provider fails and the request falls back, the interface says so rather than presenting a substitute as the model you picked. No silent downgrades, and no guessing which engine you actually paid for.
Why several models beats one, in practice
A model that is wrong is wrong confidently. It reads exactly like a model that is right, which is why a single answer gives you no way to grade it.
Running the same question across several frontier models changes that. Where they agree, you can move fast. Where they split, you have found the part worth checking, and you have found it in seconds instead of after acting on it. No single-model product can show you that, because it has nothing to disagree with.
2. Perplexity — strong at cited search
Perplexity built its own search model, Sonar, and its answers come with sources you can click. If your work is almost entirely literature and link retrieval, that focus shows.
| Plan | Price | Models |
|---|---|---|
| Pro | $20/mo · $200/yr | Sonar, GPT-5.2, Claude Sonnet 4.6, Gemini 3.1 Pro |
| Max | $200/mo · $2,000/yr | Adds Claude Opus 4.5, Sonnet 4.6 Thinking, o3-Pro, Grok 4, and Model Council |
Tradeoffs
- Model transparency. Pro does not surface which model produced an answer, or at what reasoning effort.
- A generation behind on models. GPT-5.2 and Sonnet 4.6 against GPT-5.6 and Sonnet 5.
- $200/month for multi-model. Model Council is Max-only, and it is three models.
3. ChatGPT — the default, and one lab
Plus at $20/month is the most widely used AI subscription and the most polished single product in this list. Pro at $200/month unlocks gpt-5.6, gpt-5.6-sol, gpt-5.4, o3-pro, o4-mini and Codex at 20x the limits.
Tradeoffs
- Every answer comes from OpenAI. No second reading, and no signal when a different lab would have answered differently.
- Usage is not metered visibly. You find the ceiling by hitting it.
- $200/month to reach the frontier tier.
4. Claude — excellent writing, one lab
Pro is $20/month, or $17/month billed annually at $200 upfront, and includes the current Claude models plus Claude Code. Max runs $100 to $200/month for higher limits. For long-form writing and code review it is a genuinely strong product.
Tradeoffs
- One lab, same as ChatGPT. One opinion per question.
- No multi-model comparison at any tier.
- Up to $200/month for the higher usage plans.
How to choose
- Paying for more than one AI subscription right now? That is the exact problem MODUS was built for. PILOT at $59 costs less than a third of any single $200 tier and carries a newer model from every lab.
- Want to see several models answer the same question? MODUS runs ten for $59. Perplexity runs three for $200. Nobody else offers it at all.
- Doing almost nothing but cited literature search? Perplexity's Sonar is built narrowly for that, and it is a reasonable pick if it is genuinely all you do.
- Happy inside one lab and never want a second opinion? ChatGPT Plus or Claude Pro at $20 will do it.
For most people paying real money for AI in 2026, the deciding question is simple: one model's opinion, or all of them. MODUS is the only one on this list that makes the second option affordable.
