Every few months a new model claims the top spot. For a business, the real question isn't which model wins a benchmark — it's which one fits the job you need done.
Here we compare the four model families most teams actually choose between: OpenAI's GPT, Anthropic's Claude, Google's Gemini and Meta's open Llama. Versions change fast, so we focus on lasting strengths rather than single scores.
▪The four families at a glance
A general picture based on public documentation and common usage — always test on your own tasks.
| Family | Made by | Known strengths | Access |
|---|---|---|---|
| GPT | OpenAI | All-round ability, huge tool ecosystem | API, ChatGPT |
| Claude | Anthropic | Long documents, careful writing, coding | API, Claude apps |
| Gemini | Multimodal input, very long context, Google integration | API, Gemini apps | |
| Llama | Meta | Open weights, self-hosting, customisation | Download, many hosts |

▪Closed vs open models
GPT, Claude and Gemini are closed: you rent them through an API. Llama is open-weight: you can download it from llama.com and run it yourself. Open models give privacy and control; closed models usually give the highest quality with zero infrastructure.
| Closed (API) | Open weights | |
|---|---|---|
| Setup | Minutes | Hours to days |
| Data control | Provider's terms | Fully yours |
| Cost model | Pay per token | Pay for hardware |
| Customisation | Prompts, some fine-tuning | Full fine-tuning |

▪Frequently Asked Questions
Which AI model is the best in 2026?+
There is no single best. Each family leads in different areas, and leadership changes with every release. Test on your own tasks.
Is Llama really free?+
The weights are free to download under Meta's licence, but running it needs hardware or a hosting provider, which costs money.
Can I switch models later?+
Yes, if you design for it. Keep prompts and tools separate from one provider's quirks so swapping is a config change.
