In September, 43.8% of US businesses on Ramp paid Anthropic, compared with 40.6% that paid OpenAI. On the consumer side, the picture flips: ChatGPT reaches 1.2 billion weekly users, and Similarweb still credits it with 57% of chatbot visits versus 9.6% for Claude.
That split is why the Claude vs ChatGPT question keeps coming up in budget meetings. Both vendors now sell nearly identical seat prices, both ship desktop agents that work across your files and apps, and both bundle a coding agent into paid plans. The differences sit in usage limits, context windows, admin controls, ads, and how each agent handles real work.
This guide compares Claude and ChatGPT the way a B2B buyer would: individual plans, team seats, agents, coding tools, API rates, adoption data, and trust. It ends with a pick by team and a short FAQ. Every figure links to its source.
Key Takeaways
- Seats cost the same: Claude Team and ChatGPT Business both charge $20 a seat a month billed annually for standard seats.
- Context favors Claude: paid Claude plans offer up to 1M tokens, while ChatGPT Plus tops out at 256K for reasoning.
- Agents: Cowork is merging into Claude itself, and ChatGPT Work ships with Codex built in.
- Business adoption: 43.8% of Ramp businesses paid Anthropic vs 40.6% for OpenAI in September.
- Ads: ChatGPT shows ads on Free and Go, while Anthropic says Claude will remain ad-free.

Claude vs ChatGPT pricing for individuals
At the entry level, the two are close. Claude Pro costs $17 a month billed annually ($200 up front) or $20 billed monthly. ChatGPT Plus costs $20 a month, billed monthly, with no annual option. ChatGPT also sells Go at $8 a month, which is cheaper but may include ads.
The power tiers are where the plans diverge. Claude Max costs $100 for 5x Pro usage and Claude Ultra costs $200 for 10x Pro weekly usage, no 5-hour limit for verified accounts, and $200 a month in API credits. OpenAI now sells three Pro tiers at $100, $200, and $500 a month, and only Pro 500 includes Ultrafast modes for GPT-6 Astra and GPT-6.1 Sol.
| Plan | Monthly price | What stands out | Source |
|---|---|---|---|
| Claude Free | $0 | No ads; limited usage | Claude pricing |
| Claude Pro | $17 annual / $20 monthly | Claude Code included; up to 1M context | Claude pricing |
| Claude Max | $100 | 5x Pro usage; $100/mo API credits | Claude pricing |
| Claude Ultra | $200 | 10x Pro weekly usage; $200/mo API credits | Claude pricing |
| ChatGPT Free | $0 | Ads in eligible markets; desktop Chat, Work, and Codex | OpenAI |
| ChatGPT Go | $8 | Low-cost tier that may include ads | OpenAI |
| ChatGPT Plus | $20 | Monthly billing only | OpenAI Help Center |
| ChatGPT Pro 100 / 200 / 500 | $100 / $200 / $500 | Ultrafast only on Pro 500 | OpenAI Help Center |
Limits moved recently, so recheck before you buy. OpenAI says Pro 100 and Pro 500 now include twice their previous Work and Codex allowance, while Plus usage is unchanged. On the Claude side, Max and Ultra subscribers now get a monthly API credit for building on the Claude Platform.
Claude Team vs ChatGPT Business: seat pricing and admin
Team pricing is almost a mirror image. Claude Team charges $20 per standard seat billed annually ($25 monthly) and $100 per premium seat ($125 monthly), with premium seats getting 5x the usage. ChatGPT Business charges $20 per standard seat billed annually ($25 monthly) and $100 per premium seat ($125 monthly), with no 5-hour limit on premium.
The small print is what separates them. Claude Team includes up to $500 a month in pooled API credits plus Claude Code and Cowork for teams of 2 to 150. ChatGPT Business covers 2 to 200 users, and OpenAI says that starting in December, plan usage will share one limit across ChatGPT and Codex. Heavy Codex users on Business will burn the same allowance they use for chat.
At enterprise scale, Anthropic publishes a number and OpenAI doesn't. Claude Enterprise is $20 per seat per month billed annually with a 20-seat minimum, plus usage at API rates. ChatGPT Enterprise is quote-based, and OpenAI lists data residency in 10 regions plus SCIM, RBAC, and IP allowlisting as Enterprise features.
Claude Cowork vs ChatGPT Work: desktop agents compared
Both companies now sell an agent that does multi-step work on your files and apps, not just chat. OpenAI launched ChatGPT Work on July 9, 2026 as an agent that can take action across your apps and files and stay with a project for hours. It creates sheets, slides, docs, and web apps, runs Scheduled Tasks, and uses a built-in browser on desktop.
Claude Cowork covers similar ground: scheduled tasks, a built-in browser, and work across your files and tools. Anthropic is now merging Cowork and chat into a single Claude, rolling out to Pro, Max, and Ultra first, with Team and Free to follow. An October 23 update says it's generally available on Claude Enterprise.
| Capability | Claude Cowork | ChatGPT Work | Source |
|---|---|---|---|
| Scheduled or recurring tasks | Yes | Yes, Scheduled Tasks | Claude, OpenAI |
| Built-in browser | Yes, in the desktop app | Yes, on desktop | Claude, OpenAI |
| Creates docs, slides, sheets | Yes (Slides and Docs in beta) | Yes, plus Sites web apps | Claude, OpenAI |
| App connections | Connectors and plugins | Plugins for Slack, Teams, Drive, CRMs | Claude, OpenAI |
| Free-plan access | Rolling out after paid plans | Desktop app on every plan, including Free | Claude, OpenAI |
For marketing and sales teams, the practical test is the same for both: hand the agent a recurring job you already know well. OpenAI's own example list includes turning source materials into a marketing campaign brief and preparing for a sales meeting. Run that job in each tool for two weeks and compare output quality and how much of your plan it used.
Claude Code vs Codex: which coding agent fits your team?
Coding is where the Claude vs ChatGPT debate gets the most heated, and Trends data shows searches for "chatgpt codex vs claude code" rising alongside the main query. Claude Code comes included in every paid Claude plan, from Pro up to Enterprise. OpenAI says more than 5 million people use Codex every week, and more than 1 million use it for work outside software development.
Packaging differs. OpenAI merged the Codex app into the new ChatGPT desktop app, so developers and non-developers share one install. Anthropic keeps Claude Code as its own product and points to a 680,000-line code migration finished in less than a day by an early Opus 5.5 tester as an example of long-running agentic coding.
If your engineers already live in one tool, that's usually the deciding factor. If you're choosing fresh, run the same backlog ticket through both and compare review time, not just whether the code compiles. Pay attention to limits: ChatGPT Business is moving to a shared ChatGPT and Codex usage limit in December.
Models and API pricing: Claude 5.5 vs GPT-6.1
If you build on the API, list prices are close at the mid tier. Claude Sonnet 5.5 costs $2 per million input tokens and $10 per million output tokens. GPT-6.1 Sol costs $2 input and $10 output per million tokens, with $0.10 cached input. The flagship gap is wider: Claude Opus 5.5 runs $4 input and $20 output, 40% cheaper than Opus 5 on typical workloads.
| Model | Input / output per 1M tokens | Positioning | Source |
|---|---|---|---|
| Claude Opus 5.5 | $4 / $20 | Anthropic flagship for complex work | Anthropic |
| Claude Sonnet 5.5 | $2 / $10 | Everyday tasks, docs, slides | Anthropic |
| Claude Haiku 5.5 | $0.10 / $0.50 (up to 100K tokens) | High-volume, low-cost work | Claude pricing |
| GPT-6.1 Sol | $2 / $10 | OpenAI general model | OpenAI |
| GPT-6.1 Terra | $1 / $5 | Lower-cost OpenAI model | OpenAI |
Token counts matter as much as list prices. Anthropic says Sonnet 5.5 costs up to 30% less per task than Sonnet 5 because it uses fewer tokens, so test real workloads before trusting a per-token comparison.
Who's winning: Claude vs ChatGPT adoption data
The answer depends on whether you count businesses or people. Ramp, which tracks card and bill-pay spend across more than 85,000 US businesses, found 43.8% paid Anthropic in September, up 0.25 points, while OpenAI rose 1.12 points to 40.6%. Overall paid AI adoption on Ramp reached 55.9%.
Consumer traffic tells the opposite story. Similarweb found Claude's share of chatbot visits grew from 2% to 9.6% over the 12 months through August 2026, while ChatGPT fell from 78% to 57%. ChatGPT still keeps users longer: six-month retention was 59% for ChatGPT vs 45% for Claude, though the gap has narrowed.
Plenty of teams use both. Similarweb reports that 61% of Claude users also use ChatGPT, and 14% of ChatGPT users also use Claude. Anthropic's business momentum shows up in revenue too: CNBC reported $16.8 billion in third-quarter revenue, and Anthropic filed an S-1 for a proposed IPO on October 26.
| Metric | Claude / Anthropic | ChatGPT / OpenAI | Source |
|---|---|---|---|
| Ramp businesses paying (Sep 2026) | 43.8% | 40.6% | Ramp AI Index |
| Share of chatbot visits (Aug 2026) | 9.6% | 57% | Similarweb |
| Six-month retention | 45% | 59% | Similarweb |
| Users who also use the other app | 61% | 14% | Similarweb |
| Weekly users | Not disclosed | 1.2B | OpenAI |

Ads, privacy, and trust: a real difference for buyers
This is the clearest philosophical split. OpenAI shows ads on Free and Go and says Plus, Pro, Business, and Enterprise stay ad-free. Anthropic said in February that Claude will remain ad-free, with no sponsored links and no advertiser influence on responses.
For B2B marketers, that cuts two ways. Paid business seats are ad-free on both, so your team's daily work isn't affected. But ChatGPT is now also an ad channel your buyers see, with more than 100,000 advertisers so far. GrowthCentr tracks that channel in its ChatGPT ads statistics report. On both assistants, organic visibility in answers still matters, which GrowthCentr covers in its AI search visibility guide for B2B SaaS.
Claude or ChatGPT: which should your team choose?
Use this as a starting point, then confirm with a two-week pilot on real tasks.
| Team or need | Lean toward | Why |
|---|---|---|
| Long documents, contracts, research packs | Claude | Up to 1M token context on paid plans |
| Company-wide rollout with Free users | ChatGPT | Desktop Chat, Work, and Codex on every plan |
| Engineering-heavy team | Either; pilot both | Claude Code in all paid plans vs Codex inside ChatGPT |
| Marketing and content ops | Claude, test ChatGPT Work | Ad-free, strong writing; Work handles campaign briefs |
| Sales teams on Slack or Teams | ChatGPT | Plugins and ChatGPT in Slack and Microsoft Teams |
| Published enterprise pricing | Claude | $20 per seat plus usage, 20-seat minimum |
| Data residency across regions | ChatGPT Enterprise | Data residency in 10 regions |
If the choice is still close, look at the ChatGPT alternatives for B2B teams comparison, which adds Gemini, Microsoft 365 Copilot, and Perplexity to the shortlist.
GrowthCentr's take
The named downside: both vendors keep changing limits. OpenAI reversed a planned Pro 200 cut and doubled some Work and Codex allowances, and Anthropic is mid-way through folding Cowork into the main Claude app. Whatever you buy, avoid long annual commitments for heavy agent users until usage patterns settle.
