Overview
Trainium is Amazon's custom AI training and inference chip family, developed by its Annapurna Labs division and co-designed with Marvell Technology, with over 1 million processors deployed and dedicated capacity committed to both Anthropic and OpenAI. Trainium 3 began shipping in 2026 with 30-40% better price-performance than Trainium 2, and Amazon now holds more than $225 billion in Trainium revenue commitments.
Strategic Connections
- OpenAI: OpenAI's 2026 AWS deal includes 2 gigawatts of dedicated Trainium compute capacity.
- Anthropic: Anthropic's Project Rainier facility runs roughly 500,000 Trainium2 chips, its primary dedicated AWS compute allocation.
- Amazon Web Services: AWS Trainium is developed by Amazon's Annapurna Labs division, the Israeli chip design house Amazon acquired in 2015.
- Marvell Technology: Marvell Technology co-designs AWS Trainium silicon alongside Amazon's Annapurna Labs.
- Amazon: Amazon develops its own Trainium AI training chips to reduce dependency on NVIDIA GPUs.

Strategic Risks
- Neuron SDK does not run CUDA code, creating migration friction for teams built around NVIDIA's software ecosystem
- GPU-based systems still account for roughly 60% of AWS's AI server build-out in 2026, meaning Trainium remains a minority of total capacity despite rapid growth
Future Outlook
- Trainium 4 announced for late 2026 or early 2027, promising 3x FP8 and 6x FP4 throughput over Trainium 3
- Support for NVIDIA NVLink Fusion enabling hybrid clusters mixing Trainium and NVIDIA GPUs
