Modal

Modal provides sub-second cold starts and scales from zero to thousands of concurrent containers, making it well suited for agent workflows that require burst compute or GPU access. Production-proven at companies like Lovable and Quora, Modal raised $80M in September 2025 to expand its serverless infrastructure. Its pay-per-use model with a free tier lowers the barrier for teams experimenting with compute-heavy agent tasks such as code generation benchmarks and model evaluation pipelines.
