GPT-6.1 Sol is the best AI for business use if you want one model that covers strategy, analysis, writing and day-to-day work without much compromise. Independent testing puts it one point behind GPT-6 Astra at a fifth of the price, and it is available in ChatGPT's business plans and on Azure. Pair it with a cheap model — Claude Haiku 5.5 or GPT-6 Luna — for high-volume operations, and use Claude Sonnet 5.5 where writing quality is the product.
The safest business use default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
GPT-6.1 Sol is the strongest answer here for business use — pick it when quality of output matters more than the $2.00/1M/1M input you pay for it.
Gemini 3.8 Flash handles the same job for about 63% less per token. Start here and only move up if the output is not good enough.
Claude Haiku 5.5 is the fastest of these for business use — worth it when latency is what the reader notices, not the last few points of reasoning depth.

Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for business use, what it is genuinely good at, and where we would steer you away from it.
The default answer for business use — 98/100 on the coding axis, and the model we would start with unless the price below rules it out.
OpenAI's September 29, 2026 DevDay release — a Sol-tier reasoning model that OpenAI says comes close to GPT-6 Astra on agentic coding, computer use and professional work at one fifth of Astra's price.
You need it inside ordinary ChatGPT chats today, or your prompts regularly pass 272K tokens where the rate doubles.
OpenAI's best value for serious work. GPT-6.1 Sol replaces both GPT-6 Sol and, for most teams, GPT-6 Astra: independent testing has it a point behind Astra at a fifth of the list price. Pick Astra only when the last point of capability is worth five times the bill.

The alternative to check next for business use — 98/100 on coding.
Anthropic's September 28, 2026 Sonnet — built for well-scoped everyday work like features, bug fixes, documents, slides and spreadsheets, priced at $2/$10 and close to Opus 5.5 on most of Anthropic's launch rows.
The work is long, ambiguous and multi-step — Anthropic positions Opus 5.5 for exactly that — or you need the lowest possible price, where Haiku 5.5 costs a twentieth as much.
The model most people should default to in the Claude lineup. Sonnet 5.5 lands within a few points of Opus 5.5 on most of Anthropic's launch rows, beats it on Terminal-Bench 4.0, and costs half as much. Step up to Opus 5.5 only when the task is open-ended and long.

For business use, GPT-6.1 Sol (OpenAI) is our pick. Near-Astra capability at Sol pricing — OpenAI's value pick. It costs $2/1M input and $10/1M output tokens, with a 1.05M-token context window — enough headroom for all but the largest business use jobs. Claude Sonnet 5.5 is the closest alternative if it doesn't fit your setup.
Because the work it is built for overlaps closely with business use: coding agents in Codex that need near-Astra quality at Sol pricing and computer-use and browser automation run at volume. OpenAI's best value for serious work. GPT-6.1 Sol replaces both GPT-6 Sol and, for most teams, GPT-6 Astra: independent testing has it a point behind Astra at a fifth of the list price. Pick Astra only when the last point of capability is worth five times the bill.
On a moderate month — 10M input and 2M output tokens — GPT-6.1 Sol runs about $40.00 at list price, with no batch or caching discounts applied, so treat that as a ceiling. Claude Haiku 5.5 is the cheaper route at roughly $2.00 for the same volume, if business use is high-volume enough for price to lead the decision.
Prompts above 272K input tokens are billed at $4/$15. At launch it was available in ChatGPT Work and Codex, not in regular ChatGPT conversations. Avoid it if you need it inside ordinary ChatGPT chats today, or your prompts regularly pass 272K tokens where the rate doubles. None of that rules it out for business use on its own — but if one of those limits maps onto how you actually work, take the alternative on this page seriously rather than defaulting to the top pick.
Claude Haiku 5.5 at $0.1/1M input is the budget option here. Anthropic's budget model, now with adjustable reasoning, at $0.10/$0.50. Expect a quality step down on the hardest cases — the usual pattern is to route routine business use volume to Claude Haiku 5.5 and keep GPT-6.1 Sol for the work where a wrong answer is expensive.
Claude Haiku 5.5, rated very fast against GPT-6.1 Sol's balanced. Speed matters most for interactive and high-volume work; if your business use runs in the background, the slower and more capable model is usually the better trade.
