# Parallel Execution
> Run multiple agents simultaneously
Run agents in parallel for faster results on independent tasks.

```
## Quick Start
```rust theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
use praisonai::parallel;
let results = parallel([
researcher.chat("Research topic A"),
researcher.chat("Research topic B"),
researcher.chat("Research topic C"),
]).await?;
// All three run simultaneously
```
```rust theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
use praisonai::{AgentTeam, Process};
let team = AgentTeam::new()
.agent(researcher)
.agent(analyst)
.agent(writer)
.process(Process::Parallel)
.build();
// All agents work simultaneously
```
***
## When to Use Parallel
```mermaid theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
graph TB
subgraph "Use When"
I[Independent tasks] --> P[✅ Use Parallel]
D[Dependent tasks] --> S[❌ Use Sequential]
end
classDef yes fill:#10B981,stroke:#7C90A0,color:#fff
classDef no fill:#EF4444,stroke:#7C90A0,color:#fff
classDef task fill:#6366F1,stroke:#7C90A0,color:#fff
class I,D task
class P yes
class S no
```
| Task Type | Use Parallel? |
| ------------------------ | ------------- |
| Research 3 topics | ✅ Yes |
| Translate to 5 languages | ✅ Yes |
| Write then edit | ❌ No |
| Research then summarize | ❌ No |
***
## Best Practices
If task B needs task A's output, use sequential.
Parallel calls may hit rate limits faster.
