Large Language Models ๐Ÿค–

The AI models actually powering apps and workflows right now โ€” ranked by real reported usage share (2026 developer survey data).

OpenAI Models
๐ŸŸข
#1 ยท 81.4%
OpenAI GPT
The GPT model family (GPT-4o, GPT-5 and successors) โ€” the single most-used AI model line in the world, powering ChatGPT and a huge share of AI features built into other products.
๐Ÿงฉ
#4 ยท 34.6%
OpenAI Reasoning
OpenAI's dedicated reasoning models (the "o-series") โ€” trained to think step-by-step before answering, trading speed for much stronger performance on math, logic, and complex coding tasks.
๐ŸŽจ
#5 ยท 26.6%
OpenAI Image
OpenAI's image-generation models (DALL-E and GPT-image successors) โ€” text-to-image generation built directly into ChatGPT and available via the OpenAI API.
Anthropic
๐ŸŒ
#2 ยท 42.8%
Claude Sonnet
Anthropic's mid-tier, balanced model line โ€” the default choice for most Claude API usage and Claude Code, tuned to be strong at coding and long-context reasoning at a reasonable cost.
Google
โšก
#3 ยท 35.3%
Gemini Flash
Google's fast, low-cost Gemini tier โ€” optimized for high-volume, latency-sensitive applications where full Gemini Pro reasoning power isn't needed.
๐Ÿง 
#6 ยท 25.6%
Gemini Reasoning
Google's reasoning-focused Gemini models (Gemini "Thinking" variants) โ€” designed to work through multi-step problems before responding, competing directly with OpenAI's o-series.
DeepSeek
๐Ÿ‹
#7 ยท 23.3%
DeepSeek Reasoning
DeepSeek's reasoning model line (DeepSeek-R1 and successors) โ€” an open-weight reasoning model that shocked the industry by matching top closed-source reasoning models at a fraction of the training cost.
๐Ÿณ
#9 ยท 14.3%
DeepSeek General
DeepSeek's general-purpose chat models (DeepSeek-V3 and successors) โ€” strong all-around performance, fully open-weight, and dramatically cheaper to run than most closed-source competitors.
Open-Weight Models
๐Ÿฆ™
#8 ยท 17.8%
Meta Llama
Meta's open-weight model family โ€” free to download and run yourself (via Ollama, vLLM, etc.), the model most responsible for kickstarting the modern open-weight LLM ecosystem.
๐ŸŒฌ๏ธ
#11 ยท 10.4%
Mistral
Mistral AI's model family โ€” a French AI lab known for efficient, strong open-weight and API models, popular in the EU for data-sovereignty-conscious deployments.
๐Ÿผ
#13 ยท 5.2%
Alibaba Qwen
Alibaba's open-weight Qwen model family โ€” strong multilingual (especially Chinese/English) performance, widely used both directly and as a base for fine-tuned community models.
ฮฆ
#14 ยท 5%
Microsoft Phi-4
Microsoft's small language model (SLM) family โ€” punches well above its parameter count, designed to run efficiently on modest hardware including laptops and edge devices.
Other Providers
โœ–๏ธ
#10 ยท 11.1%
X Grok
xAI's Grok model family โ€” built into X (Twitter), known for real-time access to X's own data and a more unfiltered, casual conversational style than most competitors.
๐Ÿ”ฆ
#12 ยท 7.6%
Perplexity Sonar
Perplexity's search-grounded model โ€” every answer comes with live web citations, built specifically for "AI search engine" style question-answering rather than general chat.
๐Ÿ›๏ธ
#15 ยท 1.7%
Amazon Titan
Amazon's own foundation model family, available through Amazon Bedrock โ€” a lower-profile but deeply AWS-integrated option for teams already committed to that cloud ecosystem.
๐Ÿ”ท
#16 ยท 0.8%
Cohere Command A
Cohere's enterprise-focused model โ€” built with a heavy emphasis on retrieval-augmented generation (RAG) and enterprise search use cases rather than general consumer chat.
๐Ÿ’ 
#17 ยท 0.4%
Reka
Reka AI's multimodal model family (Reka Flash and others) โ€” a smaller lab building efficient multimodal models, the least-adopted model line in this ranking so far.

Usage percentages reflect a 2026 developer-tools survey; most developers use multiple models from this list, so shares don't sum to 100%.
