Anthropic vs Modal
Modal sells serverless GPUs for code you bring; Anthropic sells finished Claude models by the token. They are not substitutes, and many agent stacks use both.

Anthropic vs Modal: key differences
Modal has no model catalog and no per-token price. A developer decorates a Python function with the GPU it needs, and Modal builds the container, autoscales it and bills per second, from $0.59 an hour for a T4 to $3.95 for an H100 at list. Anthropic is the reverse: no infrastructure to manage, just Claude models priced from $1 in on Haiku 4.5 to $10 in on Fable 5.1, with 1M context on the top tiers. Choosing between them only makes sense if you are deciding whether to host an open model yourself or rent a closed one.
In practice they tend to sit in the same stack. Claude runs the agent's reasoning and coding, while Modal hosts the pieces around it: embeddings, reranking, transcription, OCR, batch jobs, fine-tuned models and agent sandboxes. Modal's free Starter plan renews $30 of credits each month, which makes those side services cheap to try. Watch two costs, though. Non-preemptible US production runs about 3.75x list, near $14.81 an hour for an H100, and keeping containers warm turns a serverless bill into an always-on one.
What Anthropic and Modal do
Anthropic
Anthropic sells the Claude family of closed models through its own API, Amazon Bedrock, Google Vertex AI and Microsoft Foundry. The public lineup today runs from Claude Fable 5.1 at the top, released September 1, 2026, through the Opus and Sonnet tiers down to Haiku 4.5. List prices span a tenfold range, from $10 in and $50 out on Fable to $1 in and $5 out on Haiku. The top three tiers include a 1M token context window at standard pricing with no surcharge past 200K.
Example models: Claude Fable 5.1, Claude Haiku 4.5
Full Anthropic profileModal
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
