OpenAI’s latest GPT model in 2026 is called GPT-6.1 Sol, released on September 29, 2026. Its story is unusual: it is almost as smart as OpenAI’s flagship model, GPT-6 Astra, but costs about one-fifth the price. If your business pays for AI — chatbots, automation, document work — this changes your math. Here is what happened, in simple words, and what it means for you.
What Is the Latest GPT Model in 2026?
On September 29, 2026, at its DevDay developer conference, OpenAI launched GPT-6.1 Sol. It replaces GPT-6 Sol, which had launched only a week earlier. OpenAI says the new model “nearly matches” the flagship GPT-6 Astra on real work: writing and debugging code, using computers, reading documents, and running multi-step tasks.
The headline number: GPT-6.1 Sol costs $2 per million input tokens and $10 per million output tokens — about one-fifth of GPT-6 Astra’s standard prices. It can read over 1 million tokens at once, so it handles very long documents and big codebases.
GPT-6.1 Sol vs GPT-6 Astra: The Simple Difference
Think of it like cars. GPT-6 Astra (released September 3, 2026) is the luxury flagship: the absolute smartest, built for the hardest problems, and priced to match. GPT-6.1 Sol is the smart buy: roughly 95% of the real-world performance for 20% of the price.
One honest footnote: OpenAI had planned an even smarter GPT-6.1 Astra, but cancelled it after internal safety tests raised concerns. The company chose not to ship a model its own researchers flagged. That is worth knowing — and worth respecting — when you trust a provider with your business data.
For almost every business task — support bots, drafting, analysis, coding help — Sol 6.1 is the sensible pick. Astra is for research labs and problems where only the maximum will do.
What This Means for Your Business Costs
AI pricing sounds abstract until you translate it. A “token” is roughly a word fragment; a million tokens is about 750,000 words. At $2 per million input tokens, you can feed GPT-6.1 Sol the equivalent of several long books for the price of a cup of tea.
In practical terms: a customer-support chatbot handling thousands of conversations a month, a system that reads and summarizes every incoming contract, an assistant that drafts your team’s emails — all of these got roughly five times cheaper to run at near-flagship quality, compared to using the top model. Businesses that held back on AI because “the smart models cost too much” just lost their excuse.
The bottom line: 2026 is the year AI stopped being a luxury line item and became everyday infrastructure, like email or cloud storage. The companies moving first are banking the savings while competitors wait.
How Businesses Use GPT Today
The most common business uses of GPT models right now:
Support chatbots that answer customer questions day and night, in your brand’s tone, and hand tricky cases to humans.
Document work — summarizing reports, pulling key dates and amounts from contracts, turning messy notes into clean proposals.
Coding help for development teams: explaining legacy code, writing tests, and speeding up new features.
AI agents — OpenAI’s newest push. At the same DevDay event, the company showed “Dots,” a new class of agents that carry out multi-step jobs on their own, like researching suppliers or organizing files. This is where GPT is heading: not just answering, but doing.
Meeting and call summaries. Sales calls, team meetings, and client discussions get turned into action lists automatically. Nothing important slips through just because someone forgot to take notes.
