Meta vs Luminal: key differences
Meta's Model API, still in preview, serves Muse Spark 1.3 at $1.25 in and $4.25 out with 1M context, and Muse Glimmer ships as open weights. Luminal builds no models. Its compiler turns a model into native GPU kernels ahead of time, and the company sells that as early-access serverless endpoints or an on-prem license.
Teams that want Meta's closed model go to the API. Teams that fine-tune Glimmer, or any open model, and serve it themselves could use Luminal as the engine; it reports 36K tokens per second on GPT-OSS 120B across 8 H100s, about 1.4x vLLM by its own count.
What Meta and Luminal do
Meta
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
Full Meta profileLuminal
Luminal builds an inference compiler. Where vLLM and SGLang interpret a model at runtime, Luminal compiles it ahead of time into native kernels for GPUs and ASICs. Models get lowered to a small graph of 15 primitive ops, and the compiler searches over fusion, tiling, memory and scheduling choices instead of relying on hand-written rules, which it says can find optimizations like Flash Attention on its own. The compiler is open source in Rust under Apache 2.0 or MIT, runs on CUDA and Metal with ROCm on the roadmap, and works as a torch.compile backend.
Example models: GPT-OSS 120B, Llama 3 8B

Running long-horizon agents?
If your agents run past 200K tokens, compare both against Subconscious. Our inference stack treats a long-horizon trace as the primary workload, so speed, cost, and accuracy hold up deep into the trace.
