Modal vs Meta: key differences
Meta now runs a closed API. Muse Spark 1.3 offers a 1M context at $1.25 in and $4.25 out per million, with cached input at $0.15, and the endpoint speaks OpenAI, Anthropic and a stateful agentic format. A Contributor tier drops the price to $0.10 in and $0.20 out if Meta can train on your traffic. For self-hosting, Meta ships Muse Glimmer, an open-weight model distilled from Muse Spark that runs on vLLM, SGLang, llama.cpp or ExecuTorch. Meta hosts the model; Modal hosts only what you deploy.
Modal is where Glimmer, or any other open model, could run. It builds the container, scales it to zero and bills per second, which beats reserved GPUs on bursty load below roughly 80% utilization. That route suits teams that cannot hand data to Meta or want to customize the model. The Meta API suits teams that want Muse Spark's agentic and computer-use abilities, plus Muse Image at $0.01 per image, without running anything. Note the API is still in public preview.
What Modal and Meta 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 profileMeta
Meta has moved from open Llama releases toward its own closed API. Meta Superintelligence Labs builds the Muse family, and in July 2026 Meta opened a public preview of the Meta Model API with Muse Spark 1.1, a multimodal reasoning model aimed at agentic coding, tool use and computer use. The current lineup runs through Muse Spark 1.3 with a 1M token context. Standard pricing is $1.25 in and $4.25 out per million tokens, with cached input at $0.15, and the endpoint speaks OpenAI Chat Completions, Anthropic Messages and a stateful agentic format.
Example models: Muse Spark 1.3, Muse Glimmer
