SWE-1.5 has been evaluated across 5 different signals. Its strongest areas include Capabilities (50/100), Pricing (100/100), Context Window (0/100). These scores are derived from industry-standard benchmarks, community ratings, and real-world performance metrics. The composite score of 38/100 reflects a weighted combination of all tracked signals.

SWE-1.5 is available as a free, open-source model. You can run it locally or use it through various hosting providers. Some API providers may charge for hosted inference, so check individual provider pricing.

SWE-1.5 supports function/tool calling, extended reasoning/chain-of-thought, streaming responses. Function calling lets you integrate it with external APIs and tools programmatically. These capabilities determine which workflows and integrations the model can handle natively.

SWE-1.5 was developed by Windsurf. It was released on September 1, 2025. You can access it through Windsurf's API. Check our provider page for all models from Windsurf and how they compare against each other.

Pick SWE-1.5 when you need a budget-friendly option for high-volume, simpler tasks where you prioritize cost over peak performance. If your task is straightforward text completion or classification, a cheaper model might give you 90% of the quality at a fraction of the price. Run a quick benchmark on your actual use case before committing.

You can access SWE-1.5 through Windsurf's API using standard HTTP requests or their official SDK. Most providers support OpenAI-compatible endpoints, so switching between models often requires changing just the model name in your API call. Streaming is supported for real-time token-by-token output. For production use, implement proper error handling, rate limiting, and cost monitoring.
