Anthropic vs DeepInfra
DeepInfra is the price floor for open models, from $0.02 per million tokens. Anthropic charges frontier rates for Claude. The gap is large, and so is the difference in what each is for.

Anthropic vs DeepInfra: key differences
On price alone this is lopsided. DeepInfra lists Llama 3.1 8B at $0.02 per million tokens and DeepSeek V4 Flash at $0.14 in and $0.28 out, with no minimums or contracts across 150+ open models. Anthropic's cheapest model, Haiku 4.5, starts at $1 in and $5 out, and Fable 5.1 costs $10 in and $50 out. DeepInfra gets part of its edge from heavy quantization, though. Its FP4 DeepSeek V4 Pro caps context at 66K, and some reviewers report weaker output unless they pin FP8 variants. Claude's top tiers carry a full 1M window at list price.
Use DeepInfra for bulk extraction, tagging, synthetic data and budget chat backends, where cost per token decides everything and occasional quality loss is tolerable. Use Anthropic where a wrong answer costs more than the tokens, such as agentic coding, code review and long research agents. Neither offers much for custom training here, since DeepInfra has no managed fine-tuning and Claude is closed. A common split is DeepInfra for high-volume preprocessing and Claude for the reasoning steps that follow.
What Anthropic and DeepInfra do
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.
Example models: Claude Fable 5.1, Claude Haiku 4.5
Full Anthropic profileDeepInfra
DeepInfra is the price floor for open-model inference. Developers treat it as the reference point for what a token should cost, with small models like Llama 3.1 8B at $0.02 per million and DeepSeek V4 Flash at $0.14 in and $0.28 out. The catalog covers 150+ open models across text, image and speech behind a fully OpenAI-compatible API. There are no minimums, setup fees or contracts on the shared API.
Example models: DeepSeek V4 Flash, Llama 3.1 8B
