What Do Cursor 3 Parallel Agents Cost to Run?
Cursor 3 parallel agents carry no per-agent fee: each agent draws usage like any other request, with no documented cap on how many run at once. The cost hardest to offset is Cloud Agents, which need a paid plan, bill at API pricing for the selected model and ask for a spend limit on first use.
Your own API key does not cover Cloud Agents or Auto, so outside credits help only with local requests. AI Perks lists no offer from Cursor itself, but it lists 22 live offers from Anthropic, OpenAI, Google, Microsoft Azure and AWS, the five providers whose keys Cursor accepts, plus a third-party API gateway offer that matches your first deposit, up to $1,000. Prices are as of October 2026.

What Changed in Cursor 3?
Cursor 3 shipped on April 2, 2026 with the Agents Window, which runs many agents in parallel: locally, in worktrees, in the cloud and on remote SSH.
- Agents Window - a separate window you switch to from the IDE, listing local and cloud agents.
- Worktrees - each task gets an isolated Git checkout, leaving your main checkout untouched.
- /best-of-n - runs one task across several models, each in its own worktree, and compares the outcomes.
- /multitask (April 24, 2026) and Build in Parallel (May 7, 2026) - run requests or independent plan steps as async subagents.
- Cloud Agents (formerly Background Agents) - run on isolated VMs on a separate branch, without your machine online.
How Parallel Agents Draw on Your Cursor Plan
Parallel agents have no pricing of their own: Cursor publishes no multiplier, and each agent's model decides where its usage lands.
- Cursor's own models (Grok 4.7, 4.6 and 4.5, Composer 2.5) draw from one weekly pool per paid plan on The X Subscription, shared with the CLI, Cloud Agents, Grok Bot and the Grok apps.
- Third-party models (Claude, GPT, Gemini) bill at API list price from prepaid credit from the first request, on Premium and up.
- Past the pool, you wait for the weekly reset, use prepaid credit or upgrade. Requests are never slowed, and top-ups currently expire 365 days after purchase.
One trap: a subagent can run a named third-party model while the picker shows Auto, Grok or Composer, billing as third-party usage. Custom subagents inherit the parent's model unless their YAML frontmatter sets one.

What Do Cursor Cloud Agents Cost?
Cursor Cloud Agents are charged at API pricing for the selected model, and Cursor's own models draw on the weekly pool first. You set a spend limit on first use, and a larger context window can increase token usage and costs.
Rates per million tokens as of October 2026; Cursor models bill them only past the weekly pool:
| Model | Input | Output | Note |
|---|---|---|---|
| Composer 2.5 Standard | $0.50 | $2.50 | Cursor model |
| Composer 2.5 Fast (default) | $3 | $15 | Cursor model |
| Claude 4.6 Sonnet | $3 | $15 | Third-party |
| Claude 4.7 Opus | $5 | $25 | Third-party |
| GPT-5 | $1.25 | $10 | Third-party, OpenAI shutoff proposed for Nov 12, 2026 |
On Cursor's CursorBench 4.0 leaderboard as of October 2026, Composer 2.5 scores 27.7% at $0.68 per task and Opus 5.5 High 56.0% at $3.97. At those averages, five agents running one task each would cost about $3.40 versus $19.85: benchmark figures, not a quote for your repo.
Promotional Cloud Agent credits on some accounts cover Cloud Agents only and expire; see our guide to how Cursor credits work.
Which plans include Cloud Agents?
| Plan (new customers) | Price | Cloud Agents | Third-party models | Own API keys |
|---|---|---|---|---|
| Free | $0 | No | No | No |
| Plus | $8/mo | No | No | No |
| Premium | $30/mo (4x Plus usage) | Yes | API list price | Yes |
| Super | $100/mo (15x Plus) | Yes | API list price | Yes |
| Ultra | $200/mo (50x Plus) | Yes | API list price | Yes |
| Teams | $30, $100 or $200 per paid seat/mo | Yes | List price + Cursor Token Rate | Yes, + Token Rate |
Prices exclude tax. Cursor says Ultra suits power users running several agents or Automations; legacy Pro ($20), Pro+ ($60) and Ultra ($200) keep Cloud Agents for existing subscribers.
Why Your Own API Key Does Not Cover Cloud Agents or Auto
Bring-your-own-key (BYOK) in Cursor covers only chat models you explicitly select in local Chat and Agent. Cursor's support staff confirmed in June 2026 that Cloud Agents do not support BYOK, and Auto never uses your key: on individual plans it bills as a Cursor-model request from the pool.
- Paid plan required: Premium and up, or legacy Pro and up. Plus excludes own keys; Free lost them in early 2026.
- Five providers: OpenAI, Anthropic, Google, Azure OpenAI and AWS Bedrock, added in Cursor Settings > Models.
- No default key: your key runs only when you pick that provider's model, and Tab stays on Cursor's models.
- On individual plans, own-key requests skip included usage; Teams and Enterprise pay a $0.25 per million token Cursor Token Rate, Bedrock included.
- Open bug reports from October 2026 say subagents can ignore your key and bill the plan.
AWS Bedrock is the one route Cursor documents for spending existing AWS credits: inference bills to your AWS account, but only requests with an explicit Bedrock model ID go there, and the per-user toggle starts off. New to keys? Start with a free Anthropic API key.

How to Keep a Cursor 3 Parallel Agents Bill Down
Savings come from choosing where each agent's usage lands:
- Set a deliberate Cloud Agents spend limit when Cursor asks for one on first use.
- Pick the smallest Cloud Agent context window that works, since larger ones can raise token usage.
- Run routine agents on Composer 2.5 Standard: its input and output rates are one-sixth of Fast, the default (choosing needs Premium or higher).
- Save Opus for hard tasks: Claude 4.7 Opus lists at about 1.7x Claude 4.6 Sonnet.
- Pin subagent models, so you decide what each subagent bills at.
- Use /best-of-n sparingly: three models means three runs of one task.
- Route local Claude, Gemini or non-reasoning GPT work through your own key on an individual paid plan (Premium and up, or legacy Pro and up), which pays no Token Rate.
- Spread heavy batches across weeks: the pool refreshes weekly, and unused usage does not roll over.
Model Credits for Your Own Keys and Bedrock
Your own key or Bedrock is the only way provider or cloud credits can pay for Claude or GPT inside Cursor, and only for local requests. As of October 2026, AI Perks lists these live offers from the five providers whose keys Cursor accepts:
| Provider | How Cursor uses it | Live offers | Range per offer |
|---|---|---|---|
| Anthropic | Anthropic API key, all Claude models | 6 | $600 - $100,000 |
| OpenAI | OpenAI key, non-reasoning chat models | 4 | $100 - $2,500 |
| Google AI API key, Gemini only (not Vertex AI) | 5 | $2,000 - $350,000 | |
| Microsoft Azure | Azure OpenAI key | 4 | $1,000 - $150,000 |
| AWS | Bedrock, explicit Bedrock model IDs | 3 | $5,000 - $300,000 |
22 live offers, from $100 to $350,000 each. Amounts are per offer, not a stackable total, and not all are API credit, so each offer's terms decide what it pays for. Every row carries Cursor's caveats: Premium and up (or legacy Pro and up), chat models only, never Tab, Auto or Cloud Agents, and the Token Rate on Teams and Enterprise.

Step-by-Step: Set Up Parallel Agents on a Budget
Step 1: Find model credits via AI Perks for the providers you plan to use.
Step 2: Pick a plan. For new customers, Cloud Agents and own keys start at Premium ($30 a month, or $300 a year, about 16.7% less); Plus has neither.
Step 3: Add keys in Cursor Settings > Models and select that provider's model explicitly.
Step 4: Connect Bedrock if you hold AWS credits that cover the models you need, then switch on the per-user toggle.
Frequently Asked Questions
How much do Cursor 3 parallel agents cost to run?
Cursor 3 agents draw usage like any other request. Cloud Agents need a paid plan (from Premium at $30 a month for new customers), bill at API pricing for the selected model and ask for a spend limit on first use. Your own key covers only local Chat and Agent requests; AI Perks lists model credits for those.
Does Cursor limit how many parallel agents you can run?
Cursor documents no per-plan cap, and its Cloud Agents docs say you can run as many as you want in parallel. The only documented number is a default cleanup cap of 25 worktrees per machine; in practice, your weekly pool, prepaid credit and spend limit set the ceiling.
Can I use my own API key with Cursor Cloud Agents?
No. Cursor's support staff said in June 2026 that Cloud Agents do not support BYOK, and Auto ignores it too. Your own key works only for chat models you explicitly select in local Chat and Agent, on Premium and up or legacy Pro and up, and AI Perks tracks model credits for those requests.
Which Cursor plan includes Cloud Agents?
On The X Subscription, Premium ($30 a month), Super ($100), Ultra ($200) and paid Teams seats from $30 include Cloud Agents; Free and Plus do not. Legacy Pro, Pro+ and Ultra keep them for existing subscribers. Prices exclude tax, as of October 2026, and AI Perks lists model credits for local requests.
Will GPT models keep working in Cursor agents after November 12, 2026?
OpenAI has proposed November 12, 2026 as the shutoff date for Cursor-managed access to its models and says it will not supply future models. It says your own OpenAI key keeps working in local Chat and Agent. Cloud Agents never use your key. OpenAI also lists its Codex IDE extension or Amazon Bedrock and Azure gateways as alternatives.

The Bottom Line
Cursor 3 parallel agents are billed by usage, not per agent. Cap Cloud Agents with a spend limit, since your key cannot pay for them, keep routine work on Composer 2.5, and fund local requests with model credits through your own keys.
