Best ChatGPT Alternatives in 2026

Claude is the strongest ChatGPT alternative we can measure. As of October 29, 2026, Claude's latest Opus model, Claude Opus 5.5, which comes with the Pro plan, scores 86.3 on our overall table, against 78.0 for GPT-6 Sol, the model behind ChatGPT's paid plans.

Gemini (Gemini 4 Argon, 82.3) also scores above it. We rank each app by the model it runs, because that's the part we can measure. Prices and free tiers come from each vendor's own page, checked on October 23, 2026.

The ranked list: apps like ChatGPT, by model score

Each row scores the strongest model on the app's cheapest paid plan that includes it. Free tiers often run a smaller model, so they get their own column.

Scores are our overall score, 0 to 100. Supported means we have enough independent benchmark evidence to stand behind the row. Estimated means the row leans on thinner coverage, so treat a gap of a few points as noise. The scores come from the overall table, dated October 29, 2026.

A few points between two rows doesn't settle much. Claude Opus 5.5's range is 81.63–90.94 and GPT-6 Sol's is 74.67–81.26, so they don't overlap, and the lead holds across the range.

Apps we list but can't score yet

These popular apps don't name the model they run, so we don't give them a number. We'd rather leave the cell empty than guess.

  • Microsoft Copilot Microsoft

    Microsoft says only that Copilot uses "AI models selected by Microsoft".

    Paid plan
    Microsoft 365 Personal $9.99, Family $12.99 or Premium $19.99 a month
    Free tier
    Yes: a limited free version, subject to capacity

  • Perplexity Perplexity

    Perplexity picks a model for each task, and Pro lets you switch among several makers' models.

    Paid plan
    Pro
    Free tier
    Yes

  • Meta AI Meta

    Meta says Muse Spark powers the app but doesn't say which Muse Spark version it runs today.

    Paid plan
    Meta One Core $7.99 or Premium $19.99 a month, for more usage
    Free tier
    Yes, free for everyday use

  • Grok xAI

    xAI's plans page promises "Latest Grok models" without naming the one Grok Chat runs.

    Paid plan
    Plus $8 or Premium $30 a month
    Free tier
    Yes: limited chat requests

Perplexity is the one to look at if you mostly use ChatGPT to search: it answers with citations to its sources. Copilot makes sense if you already pay for Microsoft 365, since the AI comes with the subscription.

What each alternative is better at than ChatGPT

Our overall score blends eight benchmark categories. An app can trail ChatGPT overall and still lead on the job you care about. These ranks come from the same data as the table.

Claude. Claude Opus 5.5 ranks ahead of GPT-6 Sol on agentic tasks (1st against 36th), coding (1st against 13th), reasoning (4th against 14th), and knowledge (1st against 10th). Where Claude loses: the free plan doesn't include Opus, so the score in the table doesn't describe a free Claude account. Claude vs ChatGPT

Gemini. Gemini 4 Argon ranks ahead of GPT-6 Sol on agentic tasks (4th against 36th), coding (6th against 13th), reasoning (3rd against 14th), and knowledge (6th against 10th). Where Gemini loses: the free tier runs Google's Flash-Lite model, not Argon, so the score in the table doesn't describe the free experience. Gemini vs ChatGPT

DeepSeek. DeepSeek V4.1 Flash 1017 ranks ahead of GPT-6 Sol on agentic tasks (21st against 36th). Where it loses: coding (14th against 13th) and knowledge (38th against 10th). DeepSeek V4.1 Flash 1017 is an open-weight model, so you can also run it yourself. That is a different job, covered on our open-source ChatGPT alternatives page.

Which is the best free ChatGPT alternative?

Claude's free plan includes Sonnet. Anthropic's latest Sonnet model, Claude Sonnet 5.5, scores 81.8 on our table as of October 29, 2026, the highest of any free model we could name. That's higher than the 78.0 for GPT-6 Sol on ChatGPT's paid plans. Gemini, Microsoft Copilot, Perplexity, Meta AI, and Grok also have free tiers, with tighter limits or smaller models.

For a full list of free options, including models you can run yourself, see our free ChatGPT alternatives and the open-source ChatGPT alternatives you can self-host.

Is ChatGPT still the best AI?

ChatGPT's paid default isn't first on our table. As of October 29, 2026, GPT-6 Sol ranks 11th overall at 78.0, behind Claude Opus 5.5 in Claude (86.3) and Gemini 4 Argon in Gemini (82.3). ChatGPT's Pro plan is a different case: its Pro reasoning runs GPT-6 Astra, which scores 86.1 and ranks 3rd.

If ChatGPT already does what you need, a small measured gap can be outweighed by what switching costs you: your chat history, your custom GPTs, and your team's workspace. Switching makes more sense when the alternative leads on your specific job, which is what the category ranks above are for.

How we rank these apps

We score models, not apps. Each app gets the overall score of the strongest model on its cheapest paid plan that includes that model, and we name the plan. It's a weighted average across eight benchmark categories. The methodology page has the weights and the limits, and the overall table has every ranked model.

Our score doesn't measure the app around the model: web search, memory, voice, file handling, privacy terms or usage limits. Two apps running the same model can feel different. We score an app only when its maker names the model it runs, and we check prices on the vendor's own page and date them.

The same scores and rank history are available through our data API and MCP server.
