You can now train a 70B language model at home
9 months ago
- Answer.AI releases a fully open-source system to train 70b large language models on desktop computers with gaming GPUs (RTX 3090 or 4090).
- The system combines FSDP (Fully Sharded Data Parallel) and QLoRA (Quantized Low-Rank Adaptation) to enable efficient training on consumer hardware.
