    Which AI Model Should You Actually Use?

    Nine tools. Real opinions. No affiliate links. Here's what each one does, what it costs, and when it's worth paying for.

    The short answer

    If you want one subscription that handles most things: Claude Pro ($20/month). If you need research with citations: add Perplexity. If you code: add Cursor. Everyone else can stop reading here.

    Claude

    Anthropic

    $20/mo (Pro) · $100/mo (Max)

    Free: Yes — limited messages, weaker model

    Best for

    Long writing, complex instructions, document analysis, coding, structured output. Handles 200K+ tokens without losing the plot.

    Not for

    Image generation, real-time web search, plugin ecosystems.

    Projects & knowledge basesArtifacts (documents, code, charts)200K token contextFile uploads (PDF, CSV, images)Custom instructions per project

    The one most Lazy Viber guides are built for. If you buy one subscription, this is the one.

    ChatGPT

    OpenAI

    $20/mo (Plus) · $200/mo (Pro)

    Free: Yes — GPT-4o mini, limited features

    Best for

    Image generation (DALL-E), broad plugin ecosystem, voice mode, Custom GPTs, Canvas for collaborative editing.

    Not for

    Following long, specific instructions as reliably as Claude. Gets chatty.

    Custom GPTsDALL-E image generationVoice & video modeCanvas collaborative editorPlugin & action ecosystem

    The most popular. Solid at everything, best at nothing except image generation. Good default if you want one tool that does a bit of everything.

    Gemini

    Google

    $20/mo (Advanced)

    Free: Yes — Gemini 1.5 Flash, limited

    Best for

    Google Workspace integration (Gmail, Docs, Sheets, Drive). 1M token context window. Multimodal (text, image, video, audio in one conversation).

    Not for

    Precision writing tasks. Can be vague when you need it to be specific.

    Google Workspace integration1M token context windowGems (custom agents)Extensions (Maps, YouTube, Flights)Multimodal (video + audio input)

    If your entire life is Google Workspace, Gemini Advanced is worth it. Otherwise, Claude or ChatGPT will do more for the same $20.

    Grok

    xAI

    $8/mo (X Premium) · $22/mo (Premium+)

    Free: Limited on X free tier

    Best for

    Real-time X/Twitter search, DeepSearch for research, image generation (Aurora), unfiltered responses. Cheapest way into a capable model.

    Not for

    Document uploads, project organization, structured workflows. It lives on X — no standalone workspace.

    Real-time X/Twitter searchDeepSearch (multi-step research)Aurora image generationCustom Grok agentsVoice mode

    Cheapest strong model. Good for research and real-time search. Limited workspace means it can't replace Claude or ChatGPT for structured work.

    Perplexity

    Perplexity AI

    $20/mo (Pro)

    Free: Yes — limited Pro searches

    Best for

    Research with sources. Every answer comes with citations. Pro Search does multi-step research. Spaces let you organize topics.

    Not for

    Long writing, creative tasks, document processing. It finds answers — it doesn't write your essay.

    Cited sources on every answerPro Search (multi-step)Spaces for topic organizationCollections for saving researchAPI access

    The best research tool. Not a replacement for Claude or ChatGPT — a complement. Use it when you need facts, not drafts.

    Cursor

    Cursor Inc.

    $20/mo (Pro)

    Free: Yes — limited completions

    Best for

    Writing and editing code. Tab completion, inline editing (Cmd+K), Chat panel that reads your entire codebase. VS Code fork — same shortcuts, same extensions.

    Not for

    Anything that isn't code. This is an IDE, not a chatbot.

    Building web apps from plain English. Describe what you want, get a working app. Connects to Supabase for databases, deploys instantly.

    Not for

    Complex backend logic, mobile apps, enterprise software. Great for MVPs and tools, not production-grade systems.

    Codex

    OpenAI

    Included with ChatGPT Pro ($200/mo)

    Free: No

    Best for

    Autonomous coding. Give it a GitHub repo and a task description. It writes the code, creates a PR, you review. Hands-off.

    Not for

    Quick edits, learning to code, anything that needs real-time collaboration. It works alone, asynchronously.

    Autonomous PR generationGitHub integrationSandboxed executionTask-based workflowCode review interface

    Expensive but powerful. Best for developers who want to delegate entire features, not pair-program. Our Codex premium builds use it for complex automations.

    CrewAI

    $20/mo (Starter) · usage-based

    Free: Open source (self-host free)

    Best for

    Multi-agent workflows. One AI researches, another writes, another reviews. Chain tasks together. Automate entire processes.

    Not for

    Simple one-shot tasks. If you just need a single answer, this is overkill. Requires some technical setup.

    The most advanced tool on this list. For people who want AI teams, not AI chat. Our CrewAI premium builds automate entire business processes.

    Questions

    Which AI model should I use?

    For most people: Claude Pro ($20/month). It handles writing, analysis, coding, and long documents better than anything else at that price. Add Perplexity if you need real-time research. Add Cursor if you code.

    Do I need more than one AI subscription?

    Probably not. One good subscription replaces most SaaS tools. Claude or ChatGPT Plus covers 90% of use cases. Only add a second if you have a specific gap — real-time search (Perplexity) or code editing (Cursor).

    Is ChatGPT or Claude better?

    Claude is better at long writing, nuanced analysis, and following complex instructions. ChatGPT is better at image generation (DALL-E), plugins, and broad tool integration. For Lazy Viber guides, Claude is the default.

    What's the cheapest subscription worth paying for?

    Grok at $8/month (X Premium) if you mostly need search and general chat. Claude Pro or ChatGPT Plus at $20/month for serious work. Free tiers work for testing but hit limits fast.

    Do your products work with all of these?

    Each product page lists which tools it supports. Most work with Claude, ChatGPT, and Gemini. Premium build products use Cursor, Lovable, Codex, or CrewAI specifically.

    I don't code. Should I care about Cursor, Codex, or CrewAI?

    Not yet. Stick with an AI assistant (Claude, ChatGPT, Gemini, Grok, Perplexity). The build tools are for people who write code or want AI to write it for them.

    The model matters less than how you use it.
