10 Best Large Language Models of 2026

1. 1

   OpenAI GPT-6

   OpenAI's API model family, from the GPT-6 Astra flagship down to the low-cost GPT-6 Luna, plus image, voice and transcription models.

   9.3overall

   OpenAI's API model family, from the GPT-6 Astra flagship down to the low-cost GPT-6 Luna, plus image, voice and transcription models.

   Best forTeams that want the most widely used model family, a full ladder of price points and voice and image models from one vendor.

   Adoption data

   900MOpenAI reported more than 900 million weekly active ChatGPT users in 2026, the largest user base built on any model family in this list.

   OpenAI, Scaling AI for everyone (2026): “ChatGPT is where people start with AI, with more than 900M weekly active users, and we now have more than 50 million consumer subscribers.”

   OpenAI's API lineup is the broadest single catalog in this list. Its pricing page lists four text models: GPT-6 Astra for the hardest end-to-end work at $10 per million input tokens, GPT-6.1 Sol for coding and agent workflows at $2, GPT-6.1 Terra for visual reasoning and computer use at $1, and GPT-6 Luna for high-volume tasks at $0.10. The same account covers realtime voice models, speech-to-text, image generation and built-in tools such as web search at $10 per 1,000 calls. Batch processing halves input and output prices, and Flex processing trades speed for lower cost. Adoption is the strongest signal here: OpenAI reports more than 900 million weekly ChatGPT users, and 74.3% of developers in the 2026 Stack Overflow survey had used OpenAI models for work. The caveats are cost at the top end and fine print: the listed rates apply below 272K tokens of context, and data residency adds 10%. Teams with very long prompts should check the detailed pricing first.

   Strengths

   • +Widest price ladder, from $0.10 to $10 per 1M input tokens
   • +74% of developers in the 2026 Stack Overflow survey used OpenAI models for work
   • +Voice, image and text models sit under one account and bill

   Limitations

   • −Listed rates apply to context lengths under 272K tokens
   • −Data residency adds 10% to the price
   • −Flagship GPT-6 Astra output costs $50 per 1M tokens

   SummaryOpenAI offers the widest range of models and the largest documented user base, with an entry price of $0.10 per million input tokens. It is the safest default for teams that want one vendor for text, voice and images.

2. 2

   Google Gemini

   Google's Gemini API family, from Gemini 4 Argon for hard reasoning to Flash-Lite models for high-volume work, with a free tier in Google AI Studio.

   9.2overall

   Google's Gemini API family, from Gemini 4 Argon for hard reasoning to Flash-Lite models for high-volume work, with a free tier in Google AI Studio.

   Best forTeams that want a free tier to prototype on, long multimodal context and grounding in Google Search.

   Adoption data

   32 billionAlphabet said in its third-quarter 2026 earnings remarks that its first-party model APIs were processing nearly 32 billion tokens per minute, more than four times the volume a year earlier.

   Alphabet, Alphabet Q3 2026 earnings: CEO remarks (2026): “Our first-party model APIs are now processing nearly 32 billion tokens per minute — 40% more than last quarter and more than four times what we processed a year ago.”

   Gemini is the most generous family to start with. Google's pricing page shows a free tier for most models, so a team can prototype in Google AI Studio before entering a card, and the paid tier starts at $0.25 per million input tokens for Gemini 3.1 Flash-Lite. Gemini 3.8 Flash costs $0.75 per million input tokens through December 31, 2026, and the Gemini 4 Argon flagship, built for software engineering, math and multi-step agents, costs $2.00 through November 30, 2026. Search and Maps grounding include 5,000 free requests a month before per-request fees. Adoption is strong on both sides: Alphabet reports its model APIs process nearly 32 billion tokens per minute, and 54.5% of Stack Overflow's 2026 respondents used Google AI models for work. The main risk is price movement. Argon's input price doubles to $4.00 in December, Flash prices rise in January 2027, and older 2.5 models are being rerouted to newer ones. Budget with the later rates.

   Strengths

   • +Free tier lets teams prototype before paying
   • +Paid entry starts at $0.25 per 1M input tokens
   • +Alphabet reports nearly 32 billion API tokens per minute

   Limitations

   • −Gemini 4 Argon input price doubles to $4.00 on December 1, 2026
   • −Gemini 4 Argon is not available on the free tier
   • −Free tier data is used to improve Google products

   SummaryGemini combines a free tier, low Flash-Lite prices and very large API volume. Plan budgets on the higher rates that start in December 2026 and January 2027.

3. 3

   Anthropic Claude

   Anthropic's Claude API family: Claude Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5, with a 1M-token context window on most current models.

   9.1overall

   Anthropic's Claude API family: Claude Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5, with a 1M-token context window on most current models.

   Best forEngineering teams building coding agents and long-document workflows who weigh developer preference over lowest price.

   Adoption data

   75%In the 2026 Stack Overflow Developer Survey, 75% of the 11,895 respondents to the LLM vendor question had used Anthropic models for work in the past year, the highest share of any vendor.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “The two companies focused on frontier models are the top two in LLM usage: Anthropic at 75% and OpenAI at 74%.”

   Claude has the strongest pull with developers. In the 2026 Stack Overflow survey, 74.6% of respondents to the LLM vendor question had used Anthropic models for work, edging out OpenAI, and 49% said they want to work with Claude over the next year. Anthropic's pricing page lists four current tiers: Claude Fable 5.1 for long-horizon agentic work at $10 per million input tokens, Opus 5.5 at $4, Sonnet 5.5 at $2 and Haiku 5.5 at $0.10 for prompts up to 100,000 tokens. Claude 4.6 and later models, apart from Haiku 5.5, include the full 1M-token context window at standard rates, which helps teams feeding large codebases or contracts. Batch processing halves prices, and cache hits on Opus 5.5 and Sonnet 5.5 cost 5% of the input rate. The value score reflects two documented costs: mid tiers price above OpenAI's comparable models, and Anthropic says its newer tokenizer produces about 30% more tokens for the same text.

   Strengths

   • +Highest developer usage share in the 2026 Stack Overflow survey
   • +Long prompts are billed at the same per-token rate up to 1M tokens
   • +Also billed through AWS Marketplace and Azure Marketplace

   Limitations

   • −Anthropic says the newer tokenizer produces about 30% more tokens for the same text
   • −Opus 5.5 at $4 input costs twice OpenAI's GPT-6.1 Sol
   • −Haiku 5.5 prices rise fivefold for prompts over 100,000 tokens

   SummaryClaude leads developer usage and offers 1M-token context at flat rates on most current models. Expect higher effective costs than the headline rates because of the newer tokenizer.

4. 4

   DeepSeek

   DeepSeek's API with two models, deepseek-flash and deepseek-v4-pro, both with 1M-token context and off-peak pricing.

   8.2overall

   DeepSeek's API with two models, deepseek-flash and deepseek-v4-pro, both with 1M-token context and off-peak pricing.

   Best forCost-focused teams that can schedule bulk jobs outside DeepSeek's peak hours.

   Adoption data

   18.9%In the 2026 Stack Overflow Developer Survey, 18.9% of respondents to the LLM vendor question had used DeepSeek models for work, the most of any vendor outside the U.S. big three and Microsoft.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “DeepSeek 2,253 18.9%”

   DeepSeek keeps its API simple: two models, one price table. deepseek-flash, served by DeepSeek-V4.1-Flash-1017, costs $0.15 per million input tokens off-peak and $0.30 at peak, while deepseek-v4-pro costs $0.66 off-peak and $1.32 at peak. Both offer a 1M-token context window, up to 384K output tokens, JSON output and tool calls, and both accept OpenAI-format and Anthropic-format requests, which makes trials in existing agent tools easy. Peak hours are 01:00 to 04:00 and 06:00 to 10:00 UTC on weekdays; everything else, including weekends, is billed at half price. Adoption is real but narrower than the top three: 18.9% of Stack Overflow's 2026 respondents had used DeepSeek for work. The trade-offs are a short model menu, no vision input on the Pro model, and a pricing page note that DeepSeek may adjust prices, so teams should recheck before committing budgets.

   Strengths

   • +Lowest flagship-class input price in this list at $0.66 off-peak
   • +Drops into tools built for OpenAI or Anthropic APIs
   • +Cache hits cost as little as $0.003 per 1M tokens

   Limitations

   • −Peak hours double the price on weekday UTC mornings
   • −Vision input is not supported on deepseek-v4-pro
   • −Only two models, so less room to fine-tune cost against quality

   SummaryDeepSeek is the value pick, with flagship-class pricing under $1.32 per million input tokens even at peak. It suits teams that can batch work into off-peak hours.

5. 5

   Alibaba Qwen

   Alibaba Cloud's Qwen models on Model Studio, from qwen3.8-max for complex reasoning to low-cost Flash models, with regional deployment options.

   8.0overall

   Alibaba Cloud's Qwen models on Model Studio, from qwen3.8-max for complex reasoning to low-cost Flash models, with regional deployment options.

   Best forTeams that want the lowest per-token entry price and a choice of deployment regions.

   Adoption data

   10.1%In the 2026 Stack Overflow Developer Survey, 10.1% of respondents to the LLM vendor question had used Alibaba Qwen models for work in the past year.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “Alibaba Qwen 1,203 10.1%”

   Qwen gives the lowest headline price in this list. Alibaba Cloud's Model Studio pricing page lists qwen3.7-flash at $0.030 per million input tokens for prompts up to 32K tokens in the International deployment, qwen3.8-flash at $0.15 for prompts up to 1M tokens, and the qwen3.8-max flagship at $2 in and $6 out for complex reasoning and coding. Many models carry a 50% batch inference discount and context caching discounts. Prices are set separately for International, Global, Hong Kong and EU deployments, which is useful for teams with data location requirements but makes the price list long. Model Studio also serves third-party models, including DeepSeek, GLM and Kimi, so one account can cover several families. Developer adoption is moderate: 10.1% of Stack Overflow's 2026 respondents had used Qwen for work. Expect to spend time matching the model version, region and prompt-length tier before you estimate costs.

   Strengths

   • +Cheapest listed paid entry in this list at $0.030 per 1M input tokens
   • +Flagship qwen3.8-max costs $2 in and $6 out per 1M tokens
   • +Regional deployments help teams with data location rules

   Limitations

   • −Prices differ by deployment region and prompt length, which makes budgeting harder
   • −Developer usage is a tenth of the market leaders
   • −The pricing page is long and tiered, so check the exact model version

   SummaryQwen has the cheapest listed entry price and a flagship at $2 per million input tokens. Budget carefully, since rates change by region and prompt length.

6. 6

   Mistral AI

   Mistral's API and open-weight models, including Mistral Large 4, Mistral Small 4, OCR and Voxtral speech models.

   7.8overall

   Mistral's API and open-weight models, including Mistral Large 4, Mistral Small 4, OCR and Voxtral speech models.

   Best forEuropean teams and anyone who wants open-weight models they can self-host alongside a paid API.

   Adoption data

   9.8%In the 2026 Stack Overflow Developer Survey, 9.8% of respondents to the LLM vendor question had used Mistral AI models for work in the past year.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “Mistral AI 1,162 9.8%”

   Mistral sells one of the cheapest flagship models in this list and lets you run its models yourself. The pricing page states that Mistral Large costs $0.5 per million input tokens and $1.5 per million output tokens, with batch processing at 50% off and cached input at up to 90% off. Its model docs list Mistral Large 4 as an open-weight, general-purpose multimodal model and Mistral Small 4 under Apache 2.0, plus OCR 4.1 for documents and Voxtral models for speech. Mistral also hosts third-party open models such as GLM 5.3 and DeepSeek V4.1 Flash. Self-hosting is supported in a private cloud or on premises, which matters for regulated teams. Adoption trails the leaders: 9.8% of Stack Overflow's 2026 respondents had used Mistral for work. Check the license, since Large 4 uses Mistral's own open-weight license with separate terms for derivatives and production use rather than Apache 2.0.

   Strengths

   • +Flagship Large model at $0.5 in and $1.5 out per 1M tokens
   • +Open-weight models can run on your own hardware
   • +Free plan includes access to Mistral Studio

   Limitations

   • −Under 10% developer usage in the 2026 Stack Overflow survey
   • −Mistral Large 4 uses a Mistral license with separate terms for derivatives and production use
   • −Fewer first-party flagship tiers than OpenAI or Anthropic

   SummaryMistral pairs a low-priced flagship with open weights you can host yourself. It fits teams that need deployment control more than the largest ecosystem.

7. 7

   Meta Muse

   Meta's Muse models on the Meta Model API, from Muse Wonder for frontier coding to Muse Spark, plus the open-weight Muse Spark Open.

   7.7overall

   Meta's Muse models on the Meta Model API, from Muse Wonder for frontier coding to Muse Spark, plus the open-weight Muse Spark Open.

   Best forTeams that want an OpenAI-compatible API with an open-weight sibling model they can download and run.

   Adoption data

   6.3%In the 2026 Stack Overflow Developer Survey, 6.3% of respondents to the LLM vendor question had used Meta AI models for work in the past year.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “Meta AI 754 6.3%”

   Meta's developer offering now centers on the Muse models, with Llama documentation still linked from the same site. The Meta Model API lists Muse Wonder at $4.00 per million input tokens and $20.00 output for frontier coding and long-running agents, and Muse Spark 1.3 at $1.25 in and $4.25 out. A contributor version of Muse Spark costs $0.10 in and $0.20 out, but Meta states that those requests are used to improve its products. All listed API models have a 1M-token context window, and Meta says existing OpenAI SDK code works by pointing it at the new endpoint. The open-weight Muse Spark Open, an 816B model, can be served with SGLang, vLLM or Apple MLX, or fine-tuned. Meta's model pages include benchmark tables against Claude and GPT-6 models, which are vendor-run figures. Work usage is still small: 6.3% of Stack Overflow's 2026 respondents had used Meta models for work.

   Strengths

   • +Open-weight Muse Spark Open can be hosted anywhere
   • +Muse Spark 1.3 contributor tier costs $0.10 per 1M input tokens
   • +Meta publishes benchmark tables against Claude and GPT-6 models

   Limitations

   • −The $0.10 tier uses your data to improve Meta products
   • −Muse Wonder Full is available only through Muse Code subscriptions
   • −Developer usage is 6.3% in the 2026 Stack Overflow survey

   SummaryMeta Muse offers frontier and open-weight models from one vendor with very low contributor pricing. Teams with privacy rules should budget for the $1.25 private tier.

8. 8

   xAI Grok

   xAI's Grok API, led by Grok 4.7 for code and general tasks, with voice and Grok Imagine image and video APIs.

   7.3overall

   xAI's Grok API, led by Grok 4.7 for code and general tasks, with voice and Grok Imagine image and video APIs.

   Best forTeams that want one flagship model with a 500K-token context and a simple price.

   Adoption data

   7.6%In the 2026 Stack Overflow Developer Survey, 7.6% of respondents to the LLM vendor question had used xAI models for work in the past year.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “xAI 906 7.6%”

   xAI keeps its API menu short. The models page recommends Grok 4.7 for code, chat and everything outside media, at $2.00 per million input tokens and $6.00 per million output tokens with a 500K-token context window and configurable reasoning. Around it sit a Voice API covering speech-to-speech at $0.08 per minute, Grok Imagine for images from $0.02 each and video from $0.02 per second, plus Web Search and X Search tools for live data. The docs also list Batch API support, regional endpoints and integrations with Google Cloud Vertex AI and Microsoft Foundry. The single-model approach is easy to adopt but leaves no cheap tier for high-volume classification or routing, so teams pay $2.00 per million input tokens for every job. Adoption is modest: 7.6% of Stack Overflow's 2026 respondents had used xAI models for work. xAI also notes that Grok has no knowledge of current events without search tools enabled.

   Strengths

   • +One model to choose, which keeps setup simple
   • +Output price of $6.00 per 1M tokens is low for a flagship
   • +Also offered through Google Cloud Vertex AI and Microsoft Foundry

   Limitations

   • −No low-cost small model; entry price is $2.00 per 1M input tokens
   • −Grok has no current events knowledge unless search tools are enabled
   • −logprobs are not supported on grok-4.20 and newer

   SummaryGrok 4.7 is a capable single flagship at a fair output price. Teams with large volumes of simple requests will find cheaper small models elsewhere.

9. 9

   Moonshot Kimi

   Moonshot AI's Kimi API, led by the open-weight Kimi K3.1 Pro with a 1M-token context window.

   7.0overall

   Moonshot AI's Kimi API, led by the open-weight Kimi K3.1 Pro with a 1M-token context window.

   Best forTeams that want an open-weight frontier-class coding model they can also call through a hosted API.

   Adoption data

   4.0%In the 2026 Stack Overflow Developer Survey, 4.0% of respondents to the LLM vendor question had used Moonshot AI models for work in the past year.

   Stack Overflow, Technology 2026, Stack Overflow Developer Survey (2026): “Moonshot AI 479 4.0%”

   Kimi is the strongest open-weight challenger among the smaller vendors. Moonshot describes Kimi K3.1 Pro as its most capable 3T-class open-weight model, with a 1M-token context window, tool calling, vision input and reasoning effort settings. The hosted API charges $2.00 per million input tokens and $10.00 output for K3.1 Pro, $4.00 and $20.00 for the faster Highspeed variant, and $0.95 and $4.00 for the older K2.6. Context caching is automatic, so repeated prefixes are billed at the cached rate without setup. Moonshot's own launch notes report 65.7% on Terminal-Bench 4.0 for K3.1 Pro, against 58.2% for GPT-6 Astra and 66.4% for Claude Opus 5.5; these are vendor-reported numbers worth checking on your own tasks. Adoption is the weak point: 4.0% of Stack Overflow's 2026 respondents had used Moonshot models for work, so there are fewer examples and integrations to borrow from.

   Strengths

   • +Open weights plus a hosted API for the same model
   • +Moonshot reports 65.7% on Terminal-Bench 4.0 for K3.1 Pro
   • +Caching is automatic, with no manual cache setup

   Limitations

   • −Lowest developer usage among the vendors with survey data here
   • −Cheapest model, K2.6, is a previous generation
   • −Benchmark figures are published by Moonshot itself

   SummaryKimi K3.1 Pro brings open weights and a 1M-token context at a mid-range API price. It is a good second model for coding teams willing to test it.

10. 10

    Amazon Nova

    Amazon's Nova models on Amazon Bedrock, including Nova 2 Lite, with Nova Forge for custom models and Nova Act for UI agents.

    6.6overall

    Amazon's Nova models on Amazon Bedrock, including Nova 2 Lite, with Nova Forge for custom models and Nova Act for UI agents.

    Best forAWS customers who want models billed and governed inside their existing AWS account.

    Adoption data

    tens of thousandsAmazon says its Nova models and services have been adopted by tens of thousands of customers across industries.

    Amazon Web Services, Amazon Nova (2026): “Adopted by tens of thousands of customers across industries, delivering measurable impact with cost savings and gains in productivity, automation, and quality with real-world deployments.”

    Nova is Amazon's own model family, sold through Amazon Bedrock. Amazon says the models grew out of technology built for Alexa+, Amazon Ads and its stores, and the current lineup includes Nova 2 Lite, described as a fast, cost-effective reasoning model, and Nova 2 Sonic for speech-to-speech. Two services extend it: Nova Forge for building custom frontier models on top of Nova, and Nova Act for running fleets of agents that automate browser and UI workflows. Bedrock prices Nova in Standard, Priority, Flex and Batch tiers, but the per-token figures did not show on the page as we checked it, so the price here is pending. Amazon reports tens of thousands of customers, a vendor figure not split by model, and Nova does not appear among named vendors in Stack Overflow's 2026 LLM question. The main reason to choose it is operational: models, billing and access controls stay inside the AWS account a team already runs.

    Strengths

    • +Runs inside AWS accounts, billing and security controls
    • +Amazon describes broad customization options for a proprietary family
    • +New AWS customers can get up to $200 in AWS credits

    Limitations

    • −USD token prices could not be confirmed on the page as checked
    • −Not listed among named vendors in the 2026 Stack Overflow LLM question
    • −Adoption figure is Amazon's own and not broken out by model

    SummaryNova makes most sense for teams already standardized on AWS. Confirm current token prices in the Bedrock console before you compare it with other families.
