Supported GPUs & memory types

The GPU models and memory types tracked by the Ornn Data API.

GPU and memory names are exact strings. They must match spelling, casing, and spacing. URL-encode spaces and slashes in paths and query values.

GPU models

GPU name
H100 SXM
H200
A100 SXM4
B200
RTX 5090
RTX PRO 6000 WS

Fetch this list programmatically from GET /api/gpu-types so your code stays current if models are added. Use GET /api/gpu-types-free to get just the Index (free) subset — H100 SXM, H200, A100 SXM4, B200, RTX 5090. RTX PRO 6000 WS needs a Premium or Full key. See Access tiers.

Token (OTPI) labs

Lab	Label
anthropic	Anthropic
openai	OpenAI
google	Google
deepseek	DeepSeek
minimax	MiniMax
xiaomi	Xiaomi
qwen	Qwen
moonshotai	Moonshot AI
z-ai	Z.ai
mistralai	Mistral AI
meta-llama	Meta Llama

Fetch this list programmatically from GET /api/token-types, and the Index subset from GET /api/token-types-free — anthropic, openai, google, deepseek at a trailing 1 month. The other seven labs need a Premium or Full key. These are the valid lab values for /api/otpi and /api/workload.

Memory types

Fetch the live list from GET /api/memory-types (public, no key required).

Each type belongs to one of three categories: dram, flash, or module.

DRAM

Id	Memory type
mem_ddr3_4gb	DDR3 4Gb (512Mx8) 1600/1866
mem_ddr4_8gb	DDR4 8Gb (1Gx8) 3200
mem_ddr4_8gb_ett	DDR4 8Gb (1Gx8) eTT
mem_ddr4_16gb	DDR4 16Gb (2Gx8) 3200
mem_ddr4_16gb_ett	DDR4 16Gb (2Gx8) eTT
mem_ddr5_16gb	DDR5 16Gb (2Gx8) 4800/5600
mem_ddr5_16gb_ett	DDR5 16Gb (2Gx8) eTT

Flash

Id	Memory type
mem_mlc_32gb	MLC 32Gb (4Gx8)
mem_mlc_64gb	MLC 64Gb (8Gx8)
mem_slc_1gb	SLC 1Gb (128Mx8)
mem_slc_2gb	SLC 2Gb (256Mx8)

Module

Id	Memory type
mem_ddr4_udimm_16gb	DDR4 UDIMM 16GB 3200
mem_ddr5_rdimm_32gb	DDR5 RDIMM 32GB 4800/5600
mem_ddr5_udimm_16gb	DDR5 UDIMM 16GB 4800/5600

This list reflects the types tracked at the time of writing. Always treat /api/memory-types as the source of truth.
