Anthropic vs Luminal: key differences
Anthropic offers Claude Fable 5.1, Opus, Sonnet and Haiku through its API, Bedrock, Vertex AI and Microsoft Foundry, with 1M context and no surcharge past 200K tokens. Claude is a common default for coding agents. Luminal sells no model of its own. Its compiler lowers a model you bring into fused kernels ahead of time and serves it on early-access serverless endpoints or under an on-prem license.
Pick Anthropic when model quality on agentic work is the constraint. Pick Luminal when you have committed to open weights and want to squeeze more tokens per second out of the hardware; it reports 36K tokens per second on GPT-OSS 120B across 8 H100s, ahead of TensorRT-LLM and vLLM. Luminal is a 2025 startup with unpublished pricing, so expect a sales conversation.
What Anthropic and Luminal 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 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.
