Context Windows and Knowledge Boundaries

LLMs with a larger context window size can handle longer inputs and outputs. The context window, therefore, determines how much information an LLM processes before its performance starts to degrade. The knowledge cutoff date determines the end date of the data used in training.

(It's worth noting that context windows are not the be-all-and-end-all of LLMs. Practicing context engineering on models with smaller windows can even produce better results.)

As adoption continues to grow, so does the LLM industry.

• The global large language model market is projected to grow from $6.5 billion in 2024 to $140.8 billion by 2033
• 92% of Fortune 500 firms have started using generative AI in their workflows
• Generative AI is disrupting the SEO industry and changing the way we find information online
• LLM search will drive 75% of search revenue by 2028

Here's a deeper dive on some of the most important models over the last 3 years.

1. GPT-5.2

Developer: OpenAI

Release date: December 2025

Number of Parameters: Unknown

Context Window (Tokens): 400,000

Knowledge Cutoff Date: August 2025

What is it? GPT-5.2 is an iteration of the is the largest OpenAI model to date: GPT-5. In benchmarking, it outperforms earlier OpenAI models in most tests.

The ChatGPT website continues to be one of the world's most popular sites, receiving more than 5.5 billion visitors from organic search in February 2026.

Unlike earlier models that relied solely on unsupervised learning, GPT-5.2 incorporates advanced multimodal and reasoning capabilities, enabling more accurate and context-aware interactions.

It also has superior agentic capabilities and tool-calling than earlier versions. The GPT-5 lineup hallucinates less than older models, but some benchmarks show GPT-5.2 has a higher hallucination rate at 39% than GPT-5 (18%).

OpenAI has positioned GPT-5 as a major step forward, offering improved performance in tasks requiring logic, planning, and real-time understanding.

Pro users began gaining access to GPT-5 in mid-August 2025. Access will expand to Team, Enterprise, and Education users in early September.

2. Gemini 3.1 Pro

Developer: Google DeepMind

Release date: February 19, 2026

Number of Parameters: Unknown

Context Window (Tokens): 1,000,000

Knowledge Cutoff Date: January 2025

What is it? Gemini 3.1 offer is the latest Gemini model, offering a one million-token context window on release. 

This model has outstanding reasoning performance, scoring 77.1% on a test that measures the ability of an AI recognize novel patterns not fed during training. The second best model is Claude Opus 4.6 when measured on this benchmark, but it scores only 68.8%, putting Gemini well ahead of all competition right now. 

With Nano Bano also rolled in for image generation and editing, the current iteration of Gemini stands as one of the most versatile AI tools with all-around strong capabilities.

Gemini also boasts stunning SVG animations that run directly in the chat interface. It's one of differentiator that's not yet available to the same level in competitor tools yet.

3. DeepSeek-V3.2

Developer: DeepSeek

Release date: December 1, 2025

Number of Parameters: 685B total (MoE)

Context Window (Tokens): 163,840 (input) / 65,536 (output)

Knowledge Cutoff Date: Unknown (estimated mid-2025)

What is it? DeepSeek-V3.2 is a reasoning model that excels in math and coding. DeepSeek's earliest models outperformed mainstread models like OpenAI o1 at first launch. 

However, models like GPT-5.2, Claude Opus 3.6, and Gemini 3.1 and beyond have surpassed DeepSeek in several intelligence benchmarks.

(We've done a thorough DeepSeek vs ChatGPT comparison, where we put the R1 model to the test.)

That said, there's one area where DeepSeek still outshines its competitors: handling massive context windows far more cheaply.

DeepSeek V3.2 costs $0.25 per million tokens for input and $0.40 per million tokens for output. It's only a fraction of what Google, OpenAI, or Anthropic charge for comparable performance .

This is critical advantage for enterprise deployment.

Another notable feature is DeepSeek's tool-use abilities which integrates with both thinking and non-thinking modes. The ability to think and reason while using external tools makes DeepSeek a formidable competitor in the AI space.

Prominently, DeepSeek also has lower hallucination rates than leading LLMs like Gemini 3.1 and Claude Opus 4.6

On its release, DeepSeek immediately hit headlines due to the low cost of training compared to most major LLMs. Traffic to the DeepSeek website exploded in early 2025.

According to Semrush, DeepSeek gets over 262 million visits per month from more than 42.9 million unique visitors. 

4. Claude 4.6 Opus

Developer: Anthropic

Release date: February 5, 2026

Number of Parameters: Unknown (Anthropic does not disclose parameter counts)

Context Window (Tokens): 200,000 (1,000,000 in beta) / 128,000 max output

Knowledge Cutoff Date: May 2025 (reliable) / August 2025 (training data)

What is it? Claude Opus 4.6 is Anthropic's most intelligent model. Anthropic released 4.6 only a few months after Opus 4.5, seeking to expand features of the 4.5 model.

On the web, it receives 219.9+ visits from organic search each month.

Claude remains a popular model for creative tasks and coding. The latest upgrade in the flagship Opus line of models is adaptive thinking. Simply put, Claude has the ability to dynamically decide the amount of thinking effort it should put in on a task in order to maximize speed, results, and computational efficiency.

Opus 4.6 introduces agent teams, a system where multiple AI agents specializing in different tasks handle different parts of a problem in team-work style.

Each agent gets its own context window (up to 1 million tokens), and they can communicate peer-to-peer through the "Mailbox Protocol".

For complex tasks (coding, math, data analysis etc.) requiring deep context knowledge work, Claude 4.6 Opus is right up there with the best LLM tools.

5. Grok-4

Developer: xAI

Release date: July 9, 2025

Number of Parameters: Unknown (Grok-1: 314 billion)

Context Window (Tokens): 256,000

Knowledge Cutoff Date: None (uses real-time information)

What is it? Grok-4 is the newest flagship model from xAI, building on the capabilities of Grok-3 with major improvements in reasoning, speed, and real-time awareness. It’s fully integrated into X (formerly Twitter) for Premium+ subscribers.

As of launch, Grok now serves 42.7 million active users, with daily visits averaging 6.85 million since Grok-4 became available.

6. Mistral Large 2

Developer: Mistral AI

Release date: December 2, 2025

Number of Parameters: 675 billion total / 41 billion active (Sparse MoE)

Context Window (Tokens): 256,000

Knowledge Cutoff Date: Unknown

What is it? Mistral Large 3 uses a mixture-of-experts model with an impressive context window size. While it doesn't measure up to the reasoning and coding capabilities of LLMs like GPT-5.2, Claude 4.6, Gemini 3.1, and DeepSeek, it's a powerful general model with impressive multi-lingual performance.  

Mistral's main utility comes from its open-source nature and its ability to be self-hosted. That, combined with its token efficiency makes Mistral a good enterprise-level LLM even if it lags behind GPT and Claude in reasoning tasks.

7. Falcon 3

Developer: Technology Innovation Institute (TII)

Release date: December 17, 2024

Number of Parameters: 10 billion (largest variant); family includes 1B, 3B, 7B, and 10B models

Context Window (Tokens): 32,768

Knowledge Cutoff Date: Unknown 

What is it? Falcon 3 is a smart LLM that reflects where the open-source AI ecosystem is heading, with a focus on small, efficient, and accessible range of AI models.

It's not a match for leading models like Claude, GPT, and Gemini, since it's a fairly small model. 

That said Falcon 3-10B outperforms some Llama variants in Hugging Face leaderboard.

In February 2024, the UAE-based Technology Innovation Institute (TII) committed $300 million in funding to the Falcon Foundation.

8. Llama 4

Developer: Meta AI

Release date: April 5, 2025

Number of Parameters: 109 billion total / 17 billion active (Scout); 400 billion total / 17 billion active (Maverick)

Context Window (Tokens): 10,000,000 (Scout); 1,000,000 (Maverick)

Knowledge Cutoff Date: August 2024

What is it? Llama 4 is another mixture-of-models LLMs consisting of Llama 4 Scout (~109B total) abd Llama 4 Maverick (~400B total). Meta has also expanded its multilingual capabilities, adding support for eight more languages. This model now stands as the largest open-source release from Meta to date.

That said, there was significant controversy where Llama 4 Maverick benchmark results were discovered to have been manipulated by Meta to exaggerate its performance.

With independent testing revealing that Llama 4 performed worse than several models that were already months old at the time of Llama 4's release, Meta delayed the release of LLama 4 Behemoth that still hasn't been made publicly available.

The substandard results of Meta Llama make it suitable for casual tasks at best and not the best tool for jobs involving technical coding, development, and analysis tasks.

9. Inflection-3.0

Developer: Inflection AI

Release date: March 7, 2024

Number of Parameters: Unknown

Context Window (Tokens): 32,768

Knowledge Cutoff Date: Mid 2023

What is it? Inflection-2.5 was developed by Inflection AI to power its conversational AI assistant, Pi. Significant upgrades have been made, as the model currently achieves over 94% of GPT-4’s average performance while only having 40% of the training FLOPs.

Pi differentiates itself by being an empathetic AI. It doesn't measure up to flagship AI tools in technicals tasks, focusing instead on being an emotional support and displaying human-like kindness and diplomacy in its responses.

However, the company has since pivoted from its user-centric AI chatbot and is now prioritizing enterprise use.

The Microsoft-backed startup reached 1+ million daily active users on Pi in 2021, Q1.

10. Jamba

Developer: AI21 Labs

Release date: March 6, 2025 (Jamba 1.6); October 8, 2025 (Jamba Reasoning 3B); January 2026 (Jamba 2 Mini)

Number of Parameters: 398B total / 94B active (Large); 52B total / 12B active (Mini); 3B (Reasoning 3B) — all MoE

Context Window (Tokens): 256,000

Knowledge Cutoff Date: Early March 2024 (Jamba 1.5 Mini confirmed); newer versions likely later 2024

What is it? AI21 Labs created Jamba, the world's first production-grade Mamba-style large language model. It integrates SSM technology with elements of a traditional transformer model to create a hybrid architecture. The model is efficient and highly scalable, with a context window of 256K and deployment support of 140K context on a single GPU.

Jamba's core competency is maintaining high speed and efficiency when processing answers with long contexts. 

However, benchmarks show that Jamba is one of the least intelligent LLMs, especially for today's standards. And while it is faster than some counterparts like DeepSeek, Claude, and Grok, its low intelligence leaves it behind leading LLMs, more so considering that it's not the cheapest either.

11. Command A

Developer: Cohere

Release date: March 13, 2025 

Number of Parameters: 111 billion (Command A)

Context Window (Tokens): 256,000 (Command A)

Knowledge Cutoff Date: Unknown

What is it? Command A is a series of scalable LLMs from Cohere that support ten languages and 256,000-context length. This model primarily excels at retrieval-augmented generation for enterprise use.

Cohere has moved from the Command R era to Command A and its family (Reasoning, Vision, Translate) in a single year. In doing so, it doubled the context window to 256K and achieved superior inference efficiency.

They're one of the few companies building an enterprise stack (North + Embed + Rerank + Command) rather than just shipping a model.

12. Gemma 3

Developer: Google DeepMind

Release date: August 14, 2025 (Gemma 3 270M)

Number of Parameters: 270M, 1B, 4B, 12B, and 27B (Gemma 3)

Context Window (Tokens): 128,000 (Gemma 3, 4B and above); 32,000 (Gemma 3 1B & 270M; Gemma 3n)

Knowledge Cutoff Date: Unknown

What is it? Gemma is a series of lightweight open-source language models developed and released by Google DeepMind. The Gemma models are built with similar tech to the Gemini models, but Gemma is limited to text inputs and outputs only.

It doesn't compete with frontier closed models on factual accuracy or hard reasoning, but for the open-source / local-deployment community, Gemma 3 is one of the most versatile and well-supported options available. 

13. Phi-4

Release date: December 12, 2024 (Phi-4 base); February 26, 2025 (Phi-4-mini & Phi-4-multimodal); April 30, 2025 (Phi-4-reasoning family); March 4, 2026 (Phi-4-reasoning-vision)

Number of Parameters: 3.8B (Phi-4-mini), 5.6B (Phi-4-multimodal), 14B (Phi-4 base / reasoning / reasoning-plus), 15B (Phi-4-reasoning-vision)

Context Window (Tokens): 128,000

Knowledge Cutoff Date: June 2024 (Phi-4-multimodal); February 2025 (Phi-4-mini-reasoning)

What is it? Classified as a small language model (SLM), Phi-4 is Microsoft's latest release with 3.8 billion parameters. Despite the smaller size, it's been trained on 3.3 trillion tokens of data to compete with Mistral 8x7B and GPT-3.5 performance on MT-bench and MMLU benchmarks.

These models are fundamentally limited by size for certain tasks. They simply don't have the capacity to store too much factual knowledge, so users may experience factual incorrectness.

Microsoft has only just very recently released Phi-4-reasoning-vision-15B. This model combines vision understanding with structured reasoning. 

In fact, it uses a mixed reasoning/non-reasoning approach, switching automatically depending on the nature of task. For perception-based problems (OCR, captioning etc.), it uses direct inference.

When a scientific or math problem is given, the models applies chain-of-thought reasoning for more thoughtful responses.

14. XGen

Developer: Salesforce AI Research

Release date: May 2, 2025 (xGen-small); April 2025 (xLAM-2 series)

Number of Parameters: 4B–9B (xGen-small); 1B–70B (xLAM-2 series)

Context Window (Tokens): 128,000 (xGen-small); 32,000–128,000 (xLAM)

Knowledge Cutoff Date: Unknown (estimated mid-2025)

What is it? XGen series include a small model as well as a Large Action Model (LAM).

LAMs are specialized, compact language models that focus on predict the next action rather than the next word like traditional LLMs do.

They're purpose-built for AI agents that can trigger workflows, call functions, and execute tasks autonomously.

While these models aren't in competition with the top LLMs, it's part of Salesforce design philosophy to keep these models powerful in narrow applications like agentic workflows for enterprises.

15. DBRX

Developer: Databricks' Mosaic ML
