### Is Poland's economy really catching up to Spain's?  
On PPP per capita, Poland reached 82% of Spain's level in 2025, up from 60% in 2010  [1]. Nominal GDP is still about half  [2].

### Flat, predictable cost  
Each Responses API call costs the same, no matter how many tokens Parallel consumes under the hood. Scale usage confidently from 1 call to 1 million calls.

### OpenAI compatible  
Use Parallel's Responses API through OpenAI's Python or TypeScript SDKs. Switching to Parallel is a three-line diff.

```
  from openai import OpenAI - client = OpenAI(api_key=OPENAI_API_KEY)+ client = OpenAI(api_key=PARALLEL_API_KEY,+                 base_url="https://api.parallel.ai/v1")   response = client.responses.create(-     model="gpt-5.4-mini",+     model="parallel",      input="What did the SEC change for broker-dealers?",      reasoning={"effort": "low"},-     tools=[{"type": "web_search"}],  )
```

3-line diff: OpenAI SDK → Parallel
