Two years ago, choosing an AI tool meant picking a side. You signed up for ChatGPT, or you signed up for Claude, and that was your answer for the next twelve months.
That’s when this article was originally written by Tom Rankin, but it’s not how it works anymore. Across our team, different people reach for different models depending on what they’re doing, and I catch myself running the same question through two of them when the answer matters. The single-model era is over, and most of the advice written about Large Language Models hasn’t caught up.
This guide covers the models that actually matter in 2026 (at the time of updating this article), what each one is good at, what the whole stack costs once you stop pretending one subscription is enough, and where LLMs still fall over. If you want the theory behind how these things work, that’s here too, further down.
Which LLM Should You Actually Use in 2026?
The honest answer is that it depends on the job, which is a frustrating thing to hear when you just want to pick one and get on with your work. Here’s where each of the four major players currently sits.
ChatGPT runs on the GPT-5.6 family, which OpenAI made generally available on 9th July 2026. The naming changed with it, where Sol is the flagship, Terra handles balanced everyday work, and Luna is the fast, cheap option. It remains the most well-rounded of the four and the one most of your clients will have heard of.

Claude is Anthropic’s line, with Opus 5 arriving on 24th July 2026 and Sonnet 5 at the end of June. It has become the default for developers, largely on the back of coding and agentic work. If someone on your team is running an AI coding agent, there is a good chance it’s Claude underneath.

Gemini sits at 3.1 Pro on the paid Google AI Pro tier. The original version of this article treated Gemini as the option that showed promise, but that framing is out of date today. It’s now genuinely strong on research and on handling mixed inputs, so text, images, audio and PDFs in the same conversation.

Grok is on 4.5, released on 8th July 2026. Its differentiator is direct access to real-time content from X, which makes it useful for trend monitoring and for checking what people are actually saying right now, rather than what was true when the model finished training.

Now let’s take a look at a direct comparison with a focus on what each one is best at, its context window, and your monthly costs for their most popular plans.
| ChatGPT | Claude | Gemini | Grok | |
|---|---|---|---|---|
| Best at | General work, structure, templating | Coding, agents, precise tasks | Research, multimodal input | Real-time trends, live web |
| Context window | ~1M tokens | ~1M tokens | ~1M tokens | ~500k tokens |
| Consumer plan | $20/mo (Plus) | $20/mo (Pro) | $19.99/mo (AI Pro) | $30/mo (SuperGrok) |
Notice what happened to the context windows since a year or two ago, if you were paying attention back then. In early 2025, a large context window was a differentiator worth writing about, but now three of the four sit around a million tokens and the interesting question is no longer how much you can stuff in, but how well the model holds its reasoning together across a long session. That’s a much harder aspect to benchmark, and it’s where you still feel the differences across tools.
The Cost of Running More Than One Model
There’s an uncomfortable truth to the above pricing models that’s worth paying attention to early on. If you follow the advice above and use the right model for each job, you’re looking at roughly $90 a month per person before anyone has done a minute of work. A five-person team can easily spending more on AI subscriptions than most agencies spend on website hosting.
That’s what I call the fragmentation tax, and it comes with a second cost that nobody puts on an invoice. You have to manage four logins, four billing cycles, as well as four places your team’s prompts and client data end up living.
One of the solutions to that is using a consolidated service like Bluehost’s AI All-Access Pack, which bundles all four into one dashboard at $20 per user per month.

That’s roughly what a single tool costs on its own, and you switch models within the same interface or run the same prompt through multiple models to compare before deciding which answer you trust. There’s no hosting requirement, so you can be on Servebolt, Rocket.net, or Kinsta and still use it (among other hosting options).
For agencies, they also offer an Account Management Dashboard that’s worth looking at, since assigning seats and toggling client access from one admin layer beats chasing four vendors every time someone joins or leaves. A Privacy+ tier at $25 adds a sanitisation layer for sensitive prompts, which is something to consider if you’ve signed something about client data.
The trade-off with these consolidated options is that you get model access, not the full native experience. No Claude Code, no Projects or custom GPTs, and no first-party mobile apps. If one of those is load-bearing for you, run the bundle for breadth and keep a single direct subscription for the tool you actually live in day to day.
The Difference Between LLMs, AI, and Machine Learning
With the practical stuff out of the way, here’s some grounding for anyone who wants it.
Artificial Intelligence is the umbrella term for systems that do things you would normally need a human for. Think text generation, speech recognition, and natural language processing. All of it sits underneath.
Generative AI combines a foundational algorithm, a dataset, and the ability to produce new data from that set, while discriminative AI focuses on telling classes of data apart. For example, an image generator is generative while sentiment analysis is discriminative.

Machine Learning is the method of teaching a system to learn from data without explicitly programming the outcome. There’s heavy crossover with both generative and discriminative approaches in this case.
Large Language Models sit inside that overlap. They’re generative, built with machine learning, and are aimed specifically at language tasks.
What a Large Language Model Is
In short, Large Language Models are a combination of generative AI and ML technology that will only use and learn from the data they have access to. As the name implies, you use them for Natural Language Processing (NLP) tasks such as text generation or analysis.
The two components that matter more than the rest are:
- Architecture: Layers of neural networking that weight different words and phrases against each other, with embedding layers converting data into something the model can work with.
- Training data: A vast corpus of code, books, documentation, websites and video transcripts, assembled by the developer.
Around those components sit inference systems, integration layers, and safety controls that move data between your prompt and the model itself.
Generative Pre-Trained Transformers
The GPT is the framework for the model’s neural network. Generative pre-training is a machine learning approach, and the transformer architecture optimises it for language work. It’s where the capability comes from, which is why nearly every major model is built on some version of it.
Small Language Models (SLMs) are the other side of this. They’re more portable, often tuned to a narrow domain, and easier to run somewhere you control. The foundations are the same, which means that their weaknesses are too.
Where LLMs Fit Into a WordPress Workflow
Every tool you already use has bolted “something AI” on to the existing product. Your code editor has AI completion. Your SEO plugin generates meta descriptions with AI. Your content plugin creates original content for you. Your help desk drafts replies.
Most of this hooks into a model API and wraps it in the interface you were already using.
Even products like Adobe have their “AI-powered” solutions with assistants, generators, and more across an entire product line.

The 2026 shift is that models stopped answering questions and started doing multi-step work. An agent that can read a repository, make a change, run a test and open a pull request is a different category of tool from a chatbot that writes you a paragraph.
For a WordPress business, there are a few key areas where this is genuinely useful:
- Research and content planning: Working through a topic, pulling together sources, and stress-testing an angle before committing to it. This is the strongest use case and the one I would start with.
- Support: Drafting responses to common questions, summarising long ticket threads, and spotting patterns across a month of conversations that no human is going to read end to end.
- Code: Reviews, refactors, test coverage, and all the unglamorous work that always gets deferred.
- Marketing: Generating variations for marketing copy and landing pages, where the value is in volume of options rather than the quality of any single one.
I don’t think LLMs belong at every step of a workflow though. I see plenty of implementations that are there because “AI” was just on a roadmap rather than to solve a real problem, and that will show over time through long-term usage and user retention.
What LLMs Still Get Wrong
Hallucinations have not been solved. They’ve actually become harder to catch, which is worse. A 2023 hallucination was often obviously wrong. A 2026 one is presented to you with confident structure and plausible detail, and you have to actually know the subject to spot it.

Sycophancy is the failure mode people underestimate, because if you push back on a correct answer, the model will frequently fold and agree with you. If you’re using an LLM to check your reasoning, that’s a serious problem, because the tool has an incentive to tell you what you want to hear.
Long sessions degrade and context windows measured in millions of tokens don’t mean the model reasons consistently across all of it. Deep into a long conversation you start to see the logic drift, constraints forgotten, and contradictions start to appear with things established an hour earlier.

Agents fail silently, and this is what really scales badly. A chatbot giving you a wrong answer might just cost you a minute of your time, but an agent making a wrong decision at step three of a fifteen-step process and continuing confidently costs you an afternoon of unpicking.
None of this makes the tools useless though, let’s make that very clear. It makes “human-in-the-loop” verification non-negotiable, and it means that the person driving the process needs enough expertise to know when the output is wrong.
The Ethics of Using Large Language Models
The training data problem is no longer speculative. In fact, it’s being fought in court with cases against most of the major labs working through the system, covering books, music catalogues, and forum content.
For anyone publishing on the web, including ourselves here at WP Mayor, this is something that cuts both ways. Our content is very likely in these datasets. The output we all generate may carry traces of material we have no licence to.
This can quickly become a problem, because if you use LLMs to create your site’s content, this could also include copyrighted or otherwise ‘sketchy’ materials. This is apparent in tools like Udio, an AI music generator.

Tom, our writer who produced the original version of this article back in January 2025, is also a musician with two decades of experience to draw from. Here’s what he had to say about Udio in particular back then:
[Written in 2025] While Udio’s output is impressive, I can clearly hear snippets, sounds, voices, and motifs that come directly from records I know are under copyright. I’m sure other experts in various niches can identify the same in LLM output.
There’s a similar problem happening in your own business too. Standard consumer AI plans can use your prompts for training. If your team is pasting client credentials, unreleased plans, or commercially sensitive numbers into a chat window, you have made a data decision without meaning to. That’s where privacy-focused tiers come into play, and it is worth reading your provider’s terms rather than assuming.
If you don’t believe me, check out this Reddit post and the resultant Lifehacker report where it was claimed that shared conversations from Claude were easily discoverable in Google, exposing tons of provide data and information.
How I Use Large Language Models Day to Day
The highest-value use for me as CEO of a tech and media company is defintely research. Not writing per sé, but the deeper research. For example, I can get to a working understanding of an unfamiliar topic in twenty minutes instead of two hours, with the ability to ask follow-up questions that a traditional search engine would never let me ask in the past.
The second is as a thinking partner on structure. I can hand over a messy set of notes, sketches, or even chat transcripts, and ask the AI what argument is buried in them. That typically produces something I can react to, and reacting is much easier than starting.
What I don’t do is publish purely AI-generated content. Everything on WP Mayor is researched and written by a person, in some cases with the help of AI in the research and draft stages, and I’m fairly confident you can tell the difference, even if you can’t explain why.
When it’s AI-generated content copy-pasted from something like ChatGPT or Claude, the output typically falls flat in a specific way, even if you’ve trained the AI to write in your voice. It reaches for similar structures and phrasing, it often makes the same point over and over, and it never quite commits to anything.
It’s no longer a case of spotting the em dashes or obvious words to know a piece of content is written by AI. The tell is usually one of two things. The writing either takes no risks or offers a generic perspective with no personal connection or story from the author themselves.
That’s the human part that remains critical to our writing, and should to yours too.
The Practical Takeaway
If you’re starting from nothing, pick one model and use it properly for a month before adding a second. Most of the value in these tools comes from knowing how to prompt one of them well, not from having access to four and losing track of what’s working where.
Once you need more than one, or if you feel it’s time to expand your experiment, the cost factor comes into play and consolidating tools starts making sense. Whether that’s through a bundle like Bluehost’s All-Access Pack or by being ruthless about which two you actually need, you’ll find the solution that works best for you. What I don’t recommend is quietly accumulating four or more subscriptions just because each one seemed necessary in the moment, often sitting idle a few weeks later.
The models will keep moving. There was a new flagship release while I was writing this updated version, and there will probably be another one or two before you read it. Building your workflow around a specific model is a losing strategy, so focus on building it around knowing which kind of task needs which kind of model. That’s the one aspect that keeps working and applies in spite of a new model.
Have you gone back and checked whether you still need all of the models you’re paying for right now? I suspect a lot of you are carrying at least one subscription out of habit, and I caught myself doing just that with two tools as I wrote this piece.
So which models are you actually paying for and using confidently right now?
