most powerful llms for enterprise

[Last updated July 2024]

The LLMs (Large Language Models) underneath the hood of ChatGPT, Claude, Gemini, and other generative AI tools are the tech your company needs to understand. LLMs make chatbots possible (internal and customer-facing), can assist in increasing coding efficiency, and are the driving force behind why Nvidia exploded into the most valuable company in the world. 

Model size, context window size, performance, cost, and availability of these LLMs determine what you can build and how expensive it is to run. 

Here are the important stats of the most powerful LLMs available – from the GPT-4o API to the world’s best open-source models.

LLMs (Large Language Models) for enterprise systems

OpenAI LLMs

ChatGPT and OpenAI are household names when it comes to large language models (LLMs). They started the generative AI firestorm with $10 billion in Microsoft funding and their GPT models have been at the top of the best LLMs available ever since. 

Last time we updated this article, GPT-5 wasn’t launched but Sam Altman had already told Stanford students that GPT-4 would be the “dumbest” model anyone would have to use again.

GPT-4o – GPT-4o is faster, cheaper, and more human than GPT-4 Turbo (and other leading models). GPT-4o has a 128K context window, is multimodal, and generates text 2x faster. GPT-4o is 50% cheaper than GPT-4 Turbo, across both input tokens ($5 per million) and output tokens ($15 per million). 

    • Model Size: 1.76 trillion parameters (unconfirmed by OpenAI)
    • Context Window Size: 128k tokens
    • Max Output: 4k tokens
    • Vision: Yes
    • Audio: Yes
    • Knowledge Cutoff: Oct 2023
    • Performance: LMSYS Chatbot Arena Leaderboard
    • Availability: Developer API, ChatGPT Plus, ChatGPT Enterprise
    • Cost: Input: $5 per 1M tokens | Output: $15 per 1M tokens

 

GPT-4 Turbo – GPT-4 Turbo is faster, has a bigger context window (128k tokens), and is significantly cheaper than GPT-4. On top of being one of the best LLMs available for developers via API, GPT-4 Turbo also has vision capabilities. It’s not as good as GPT-4 at complex logic but it hallucinates less, is more stable, and better for real-time interactions. 

    • Model Size: 1.76 trillion parameters (unconfirmed by OpenAI)
    • Context Window Size: 128k tokens
    • Max Output: 4k tokens
    • Vision: Yes
    • Audio: No
    • Knowledge Cutoff: Dec 2023
    • Performance: LMSYS Chatbot Arena Leaderboard
    • Availability: Developer API, ChatGPT Plus, ChatGPT Enterprise
    • Cost: Input: $10.00 per 1M tokens | Output: $30.00 per 1M tokens

GPT-4 – GPT-4 is more expensive than GPT-4 turbo and better at complex tasks. Compared to GPT-3.5 Turbo, it’s more advanced in logic, math, and general applications – making it better at code generation. GPT-4 also has vision capabilities and is one of the most popular, high-performing LLMs available for developers via API.

 

GPT-3.5 Turbo – GPT-3.5 Turbo is the most affordable LLM from OpenAI. It’s not as good at logic, doesn’t include vision, and doesn’t sound as human as GPT-4o or 4 Turbo. But for the right use cases, the low cost makes it a great option. 

  • Model Size: 175 billion parameters
  • Context Window Size: 16k tokens
  • Max Output: 4k tokens
  • Vision: No 
  • Knowledge Cutoff: September 2021
  • Performance: OpenAI GPT-3.5 benchmarks
  • Availability: Developer API, ChatGPT Plus, ChatGPT Enterprise
  • Cost: Input: $0.50 per 1m tokens | Output: $1.50 per 1 million tokens

Anthropic LLMs

Anthropic was founded by ex-OpenAI VPs who wanted to prioritize safety and reliability in AI models. They moved slower than OpenAI but their Claude 3 family of LLMs were the first to take the crown from OpenAI GPT-4 on the leaderboards in early 2024. Anthropic released Claude 3 Sonnet to outperform GPT-4o and all of their own Claud 3 models in intelligence, speed, and cost. 

 

Claude 3.5 Sonnet – The fastest, most cost-efficient, and highest-performing LLM as of 6.20.24 – Claude 3.5 Sonnet operates at twice the speed of Claude 3 Opus. It’s especially good at code generation – Claude 3.5 Sonnet solved 64% of coding problems, outperforming Claude 3 Opus which solved 38%.

It also introduces a new way to use Claude that isn’t just a chat UI called Artifacts. When you generate content like code snippets, text documents, or website designs, these Artifacts appear in a dedicated window alongside the conversation.

Claude 3 Opus – This is Anthropic’s most powerful LLM for highly complex tasks – from vision functions to code generation. It was the first model to beat GPT-4 on many benchmarks – including undergraduate level knowledge and graduate level reasoning. 

Its 200k context window is matched with near-perfect recall in needle in a haystack (NIAH) scenarios. Claude 3 Opus was the first LLM to beat GPT-4 Turbo on the Chatbot Arena Leaderboard. 

Claude 3 Opus use cases

  • Task automation: plan and execute complex actions across APIs and databases, interactive coding
  • R&D: research review, brainstorming and hypothesis generation, drug discovery

New LLMs specific for software development

Claude 3 Opus – Claude 3 is winning over developers for code generation when compared to GPT-4 and Github Copilot. Its 200k context window size makes it ideal for pasting large samples of code, refactoring code, and general coding tasks. 

Opus outperforms other models on most of the common evaluation benchmarks for AI systems, including undergraduate level expert knowledge (MMLU), graduate level expert reasoning (GPQA), basic mathematics (GSM8K), and more. 

Code Llama – In benchmark testing, Code Llama outperformed state-of-the-art publicly available LLMs on code tasks. It has the potential to make workflows faster and more efficient for developers and lower the barrier to entry for people learning to code.

Code Llama is available in three models:

  • Code Llama: the foundational code model
  • Code Llama Python: specialized for Python
  • Code Llama Instruct: fine-tuned for understanding natural language instructions (e.g., code me a website in HTML with these features)

Code Llama supports many of the most popular languages being used today – including Python, C++, Java, PHP, Typescript (Javascript), C#, and Bash. It can also be used for code completion and debugging.

Three sizes of Code Llama are being released with 7B, 13B, and 34B parameters, respectively. Each of these models is trained with 500B tokens of code and code-related data. The 7B and 13B base and instruct models have also been trained with fill-in-the-middle (FIM) capability, allowing them to insert code into existing code.

Code Llama is free for research and commercial use.
