## How they compare

Inference.net is less a Claude competitor than a way off closed APIs for specific tasks. Its Inference Gateway routes traffic to open, closed or custom models under one key, captures every request, and turns that traffic into eval and training datasets. It then fine-tunes a task-specific model and deploys it on a dedicated GPU with a 99.99% uptime target. Its Batch API takes up to 1M requests per file with completion windows from 24 hours to 7 days, priced off spare GPU capacity. Anthropic sells general Claude models by the token, strongest on agentic coding and long research.

A realistic setup uses both. Claude serves broad, hard or changing tasks. Once a narrow workload such as extraction or classification settles, Inference.net can distill it into a smaller model that costs less and responds faster. Its spare-capacity fleet suits batch better than strict real-time SLAs, and public benchmarks and price comparisons are scarce, so buyers rely on the vendor's numbers. Anthropic remains the better fit for open-ended work where a small fine-tune would miss cases.

## What each one does

### 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.

### Inference.net

Inference.net started as a buyer of last resort for idle GPU time. Its scheduler aggregates small unused chunks of capacity across data centers and runs models on them, and it passes the steep discounts it gets from those data centers on to customers. That origin still shows in its OpenAI-compatible Batch API, which takes up to 1M requests per file with completion windows from 24 hours to 7 days and far higher headroom than synchronous limits.

## Which is best, and when

### Choose Anthropic for

- Open-ended coding and research tasks
- Workloads that change too often to distill
- Real-time agents with long context

### Choose Inference.net for

- Distilling a settled Claude workload into a cheaper model
- Very large offline jobs through the Batch API
- Capturing traffic for evals and training data
