Modal vs DeepSeek: key differences
DeepSeek is a lab with a cheap API. V4.1 Flash costs $0.30 in and $1.20 out at peak and V4 Pro $1.32 in and $3.96 out, both with 1M context and 384K output, and every hour outside the peak windows costs half. Cache hits are priced in cents per million. Modal is serverless GPU compute with no catalog, so using DeepSeek there means bringing the MIT-licensed weights from Hugging Face and your own serving code, then paying per second for the GPUs, with an H100 listed at $3.95 an hour.
The API wins on price and effort for most teams. Modal earns its place when you need control the API cannot give: a fine-tuned DeepSeek checkpoint, a custom serving stack, or keeping data off DeepSeek's hosted API, which stores data in China. That control has costs. Cold starts come from loading weights, and keeping containers warm turns the serverless bill into an always-on one. DeepSeek's own risk is frequent retirements and repricing, like the August 2026 switch to peak and off-peak rates.
What Modal and DeepSeek do
Modal
Modal is serverless compute with GPUs attached. A developer decorates a Python function with the hardware it needs, such as gpu="H100", and Modal builds the container, schedules it, autoscales it and scales it back to zero. Billing runs per second with no minimum increment, from $0.59 an hour for a T4 to $3.95 for an H100 at list. Containers can hold up to 8 GPUs across T4 through B300.
Example models: none hosted by default; teams deploy their own, such as open LLMs on vLLM or Whisper
Full Modal profileDeepSeek
DeepSeek is the Chinese lab whose open-weight models reset price expectations for the whole market. Its API now serves two models, both with 1M context and 384K max output. V4.1 Flash shipped September 10, 2026 with built-in image understanding at $0.30 in and $1.20 out at peak. V4 Pro, generally available since August 13, costs $1.32 in and $3.96 out at peak. Cache hits cost a few cents per million or less, and the weights ship on Hugging Face under an MIT license.
Example models: DeepSeek V4.1 Flash, DeepSeek V4 Pro
