OpenAI’s GPT-5 is gaining the place it issues most: Enterprise

Sam Altman turned OpenAI right into a cultural phenomenon with ChatGPT.

Now, three years later, he is chasing the place the actual cash is: Enterprise.

Final week’s rollout of GPT-5, OpenAI’s latest synthetic intelligence mannequin, was rocky. Critics bashed its less-intuitive really feel, in the end main the corporate to revive its legacy GPT-4 to paying chatbot prospects.

However GPT-5 is not concerning the client. It is OpenAI’s effort to crack the enterprise market, the place rival Anthropic has loved a head begin.

One week in, and startups like Cursor, Vercel, and Manufacturing unit say they’ve already made GPT-5 the default mannequin in sure key merchandise and instruments, touting its sooner setup, higher outcomes on advanced duties, and a lower cost.

Some firms stated GPT-5 now matches or beats Claude on code and interface design, an area Anthropic as soon as dominated.

Field, one other enterprise buyer, has been testing GPT-5 on lengthy, logic-heavy paperwork. CEO Aaron Levie informed CNBC the mannequin is a “breakthrough,” saying it performs with a degree of reasoning that prior methods could not match.

Behind the scenes, OpenAI has constructed out its personal enterprise gross sales workforce — greater than 500 folks underneath COO Brad Lightcap — working independently of Microsoft, which has been the startup’s lead investor and key cloud associate. Prospects can entry GPT fashions by way of Microsoft Azure or go on to OpenAI, which controls the API and product expertise.

Nonetheless, the economics are brutal. The fashions are costly to run, and each OpenAI and Anthropic are spending huge to lock in prospects, with OpenAI on monitor to burn $8 billion this 12 months.

GPT-5 is considerably cheaper than Anthropic’s top-end Claude Opus 4.1 — by an element of seven and a half, in some circumstances — however OpenAI is spending enormous quantities on infrastructure to maintain that edge.

For OpenAI, it is a push to win prospects now, get them locked in and construct an actual enterprise on the again of that loyalty.

Cursor, nonetheless a serious Anthropic buyer, is now steering new customers to OpenAI. The corporate’s co-founder and CEO Michael Truell underscored the change throughout OpenAI’s launch livestream, describing GPT-5 as “the neatest coding mannequin we have ever tried.”

Truell stated the change applies solely to new sign-ups, as present Cursor prospects will proceed utilizing Anthropic as their default mannequin. Cursor maintains a committed-revenue contract with Anthropic, which has constructed its enterprise on dominating the enterprise layer.

As of June, enterprise makes up about 80% of its income, with annualized income rising 17x year-over-year, stated an individual accustomed to the matter who requested anonymity with a purpose to focus on firm knowledge. The corporate added $3 billion in income in simply the previous six months — together with $1 billion in June alone — and has already signed triple the variety of eight- and nine-figure offers this 12 months in comparison with all of 2024, the particular person stated.

Anthropic stated its enterprise footprint extends far past tech.

Claude powers instruments for Amazon Prime, Alexa, and AIG, and is utilized by high gamers in pharma, retail, aviation, {and professional} providers. The corporate is embedded throughout Amazon Net Providers, GCP, Snowflake, Databricks, and Palantir — and its offers are likely to broaden quick.

Common buyer spend has grown greater than fivefold over the previous 12 months, with over half of enterprise shoppers now utilizing a number of Claude merchandise, the particular person stated.

Excluding its two largest prospects, income for the remainder of the enterprise has grown greater than elevenfold year-over-year, the particular person stated.

Even with that broad attain, OpenAI is gaining floor with enterprise prospects.

GPT-5 API utilization has surged since launch, with the mannequin now processing greater than twice as a lot coding and agent-building work, and reasoning use circumstances leaping greater than eightfold, stated an individual accustomed to the matter who requested anonymity with a purpose to focus on firm knowledge.

Enterprise demand is rising sharply, significantly for planning and multi-step reasoning duties.

GPT-5’s traction over the previous week reveals how shortly loyalties can shift when efficiency and value tip in OpenAI’s favor.

AI-powered coding platform Qodo just lately examined GPT-5 towards top-tier fashions together with Gemini 2.5, Claude Sonnet 4, and Grok 4, and stated in a weblog put up that it led in catching coding errors.

The mannequin was typically the one one to catch essential points, equivalent to safety bugs or damaged code, suggesting clear, targeted fixes and skipping over code that did not want altering, the corporate stated. Weaknesses included occasional false positives and a few redundancy.

Vercel, a cloud platform for net functions, has made GPT-5 the default in its new open-source “vibe coding” platform — a system that turns plain-English prompts into dwell, working apps. It additionally rolled GPT-5 into its in-dashboard Agent, the place the corporate stated it has been particularly good at juggling advanced duties and considering by way of lengthy directions.

“Whereas there was a variety of competitors already in AI fashions, Claude was simply proudly owning this area. It was by far one of the best coding mannequin. It was not even shut,” stated Malte Ubl, CTO of Vercel. “OpenAI was simply not within the sport.”

That modified with GPT-5.

“They a minimum of caught up,” Ubl stated. “They’re higher at some stuff, they’re worse at different stuff.”

He stated GPT-5 stood out for early-stage prototyping and product design, calling it extra artistic than Claude’s Sonnet.

“Historically, you need to optimize for the brand new mannequin, and we noticed actually good outcomes from the beginning,” he stated concerning the ease of integration.

JetBrains has adopted GPT-5 because the default in its AI Assistant and in Kineto, a brand new no-code device for constructing web sites and apps, after discovering it might generate easy, single-purpose instruments extra shortly from person prompts. Developer platform Manufacturing unit stated it collaborated carefully with OpenAI to make GPT-5 the default for its instruments.

“In relation to getting a very good plan for implementing a fancy coding answer, GPT-5 is quite a bit higher,” stated Matan Grinberg, CEO of Manufacturing unit. “It is quite a bit higher at planning and having coherence over its plan over a protracted time frame.”

Grinberg added that GPT-5 integrates nicely with their multi-agent platform: “It simply performs very properly with a variety of these high-level particulars that we’re managing concurrently the low-level implementation particulars.”

Pricing flexibility was a significant factor in Manufacturing unit’s resolution to default to GPT-5, as nicely.

“Pricing is generally what our finish customers care about,” stated Grinberg, including that cheaper inference now makes prospects extra comfy experimenting. As an alternative of second-guessing whether or not a query is value the price, they will “shoot from the hip extra readily” and discover concepts with out hesitation.

Anton Osika, co-founder and CEO of Lovable, an organization that builds an AI-powered device that lets anybody create actual software program companies with out writing a single line of code, stated his workforce was beta testing GPT-5 for weeks earlier than it formally launched and was “tremendous pleased” with the advance.

“What we discovered is that it is extra highly effective. It is smarter in lots of advanced use circumstances,” Osika stated, including that the brand new mannequin is “extra liable to take actions and mirror on the motion it takes” and “spends extra time to ensure it actually will get it proper.”

Field‘s Levie stated the largest features for him confirmed up in enterprise workflows that don’t have anything to do with writing code. His workforce has been testing the mannequin for weeks on advanced, real-world enterprise knowledge — from hundred-page lease agreements to product roadmaps — and located that it excelled at issues that tripped up earlier AI methods.

Levie added that for company use, the place AI brokers run within the background to execute duties, these step-change enhancements are essential, and might flip GPT-5 into an actual breakthrough for work automation.

“GPT-5 has carried out unbelievably nicely — actually OpenAI’s greatest mannequin — and in a lot of our assessments it is one of the best obtainable,” he stated.
