Amazon engineers are reportedly distilling Anthropic’s large language models (LLMs) to create smaller, cheaper versions — a move to sidestep rising costs ahead of Amazon Web Services’ planned shift to token-based pricing for its Bedrock AI platform.
The distillation process strips down Anthropic’s models — such as Claude — into leaner, faster alternatives that still mimic the original’s behavior. Engineers are using the technique internally to reduce compute expenses before the new billing model takes effect, sources told The Decoder.
Why Amazon Is Pushing for Cheaper AI
Amazon’s Bedrock service currently charges a flat rate for model access. Token-based pricing — where users pay per input and output token — is expected to roll out soon. That shift threatens to significantly increase costs for companies running high-volume AI workloads.
Token-based pricing is not a small tweak. It can multiply monthly bills for customers who rely on long conversations or large document processing.
Amazon itself runs many internal AI workloads. Distilling Anthropic models lets the company keep performance close to the original while slashing the number of tokens consumed — and therefore the cost.
How Distillation Works in Practice
Knowledge distillation trains a smaller “student” model on the outputs of a larger “teacher” model. The student learns to replicate the teacher’s behavior with far fewer parameters.
Key steps Amazon engineers are reportedly taking:
- Training on teacher outputs: The student model is fed thousands of responses from Anthropic’s Claude to mimic its reasoning patterns.
- Compressing the architecture: The resulting model uses less memory and fewer GPU cycles, making inference cheaper and faster.
- Fine-tuning for specific tasks: The distilled version is tailored for common Amazon use cases — such as summarization, code generation, and customer support triage.
This approach avoids the full cost of running Claude every time a request is made. It also reduces latency, since the smaller model processes requests quicker.
Potential Risks and Licensing Questions
Distilling another company’s proprietary model raises legal and ethical issues. Anthropic’s terms of service may restrict using its models to train competing systems without explicit permission.
- Licensing gray areas: Amazon’s use of Claude outputs to train a separate model could violate Anthropic’s API terms, which typically forbid using outputs to develop competing AI systems.
- Quality trade-offs: Distilled models often lose nuance and accuracy on edge cases. They may hallucinate more or fail on complex reasoning tasks.
- Dependency on Anthropic: Amazon still relies on Anthropic for the teacher model’s knowledge. Any updates to Claude would not automatically transfer to the distilled version.
One former Amazon AI engineer told The Decoder: “This is a band-aid, not a fix. You save money now, but you lose the ability to track improvements from the original model.”
What This Means for Bedrock Customers
Amazon’s move could signal to Bedrock customers that distillation is an acceptable cost-saving strategy. If Amazon itself cherry-picks parts of Anthropic’s models, other enterprises may follow suit.
- Lower entry barriers: Smaller companies may adopt distilled models to reduce their token bills.
- Market pressure: Anthropic and other model providers may tighten licensing or raise prices to prevent wholesale distillation.
- Platform lock-in: Amazon could offer its own distilled versions as first-party options, pulling customers deeper into AWS.
The token-based pricing change is expected in the coming months. Until then, Amazon’s engineers will continue quietly trimming down Anthropic’s models — and saving millions.
