The big companies & their AI models
An interactive map to understand each AI's architecture, when to use it, what it's for, and how to integrate it into your data pipelines.
OpenAI
Creators of ChatGPT and the GPT family. In September 2026 they launched GPT-6 in three sizes: Astra, Sol and Luna.
GPT-6.1 Sol$2 / $10 per M tokens
The balanced model of the GPT-6 family (launched September 22, 2026, now at version 6.1): strong reasoning and speed at half the price of its GPT-5.6 equivalent. Since October 8 it has an Ultrafast mode up to 8x faster, at $12 / $60 per M tokens.
GPT-6 Luna$0.10 / $0.50 per M tokens
The budget GPT-6 model, built for bulk, repetitive tasks where cost per token rules.
Anthropic
Creators of Claude. Between September and October 2026 they refreshed all three tiers: Opus 5.5, Sonnet 5.5 and Haiku 5.5.
Claude Opus 5.5$4 / $20 per M tokens
Claude’s large model (September 22, 2026). It matches Claude Fable 5.1 on most tasks and costs 40% less to run than Opus 5. It ships with adaptive thinking.
Claude Sonnet 5.5$2 / $10 per M tokens
Claude’s middle tier (September 28, 2026): 30% faster and up to 30% cheaper than Sonnet 5. The default model for most workflows.
Claude Haiku 5.5$0.10 / $0.50 per M tokens (prompts up to 100K)
Claude’s small model (October 7, 2026), presented as the fastest, cheapest and most capable of its size. Built for high volume.
Google DeepMind
Creators of Gemini, built into Google Workspace, Android and now Windows. In September 2026 they unveiled Gemini 4 Argon and the Gemini 3.8 family.
Gemini 4 Argon$2 / $10 per M tokens until Nov 30; then $4 / $20
Google’s most capable model. Announced on September 30 for cybersecurity defenders, it has been open to everyone since October 13, 2026: Gemini app (Pro and Ultra), AI Studio, API and Gemini Enterprise.
Gemini 3.8 Flash$0.75 / $3.75 per M tokens (doubles Jan 1, 2027)
Google’s fast model (September 2, 2026): better reasoning and coding at lower cost. Its promotional price runs until December 31, 2026.
DeepSeek
Chinese lab behind very low-cost open models. In October 2026 it was closing a round of at least $12 billion and preparing a Hong Kong IPO.
DeepSeek ReasonerVery low / open weights
DeepSeek’s reasoning line, with open weights and an API compatible with the OpenAI SDK. The API alias always points to the current version.
Meta AI
Meta moved from the Llama family to Muse Spark, its model line for Meta AI and the API.
Muse Spark 1.3$1.25 / $4.25 per M tokens
The September 2026 release of Muse Spark: it makes about 20% fewer tool calls than 1.2 to solve the same task. A much cheaper “Contributor” variant trains on user traffic.
Mistral AI
French lab building open-weight models, the leading European option for anyone who needs data sovereignty.
Mistral Large 4API preview; open weights at the end of October
Mistral’s largest model (October 6, 2026): a mixture of experts with over a trillion parameters, about 49 billion active, image input and a one-million-token context. Trained in its own EU data centers.
xAI
Elon Musk’s AI company, maker of Grok, built into X.
Grok 4.7$2 / $6 per M tokens
The September 2026 release of Grok, on a larger base model than Grok 4.6. Its benchmark results, for now, have only been published by xAI.
