Anthropic vs Crusoe: key differences
Anthropic sells Claude, from Fable 5.1 at $10 in and $50 out to Haiku 4.5 at $1 in and $5 out, with a 1M window on the top tiers and no surcharge past 200K. Fable cache reads cost $0.25 per million. Crusoe serves open models, including DeepSeek V4 Pro, GLM 5.3 and Kimi K2.6, at $0.05 to $1.74 in and $0.20 to $4.40 out per million, so even its top output rate sits below Haiku's. Both target agent loops that reread prefixes. Anthropic does it with cheap cache reads. Crusoe does it with MemoryAlloy, a cluster-wide KV cache that it claims gives up to 9.9x faster time to first token versus vLLM on prefix-heavy work. Context on Crusoe varies by model.
Claude wins on quality and reach. It posts top-tier results on SWE-bench Pro, Claude Code made it a default in many engineering teams, and the same models run on the API, Bedrock, Vertex AI and Microsoft Foundry. Fable always thinks, though, so latency and output tokens per task run high. Crusoe wins on control. Open weights, serverless LoRA fine-tuning, dedicated endpoints with SLAs and raw GPU clusters on Kubernetes or Slurm all come from one vendor that owns its power and data centers. Its serverless catalog is small and its speed numbers are its own. Teams that need Claude's coding quality should stay. Teams that want to fine-tune an open coding model and serve it cheaply fit Crusoe.
What Anthropic and Crusoe 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 profileCrusoe
Crusoe started in 2018 turning wasted natural gas into power for computing and has since become a vertically integrated AI infrastructure company: it sources energy, builds data centers and rents GPUs through Crusoe Cloud. It designed and built the Abilene, Texas campus behind the OpenAI and Oracle Stargate project, planned at 1.2 GW, and in March 2026 announced an adjacent 900 MW campus for Microsoft. On September 17, 2026 it closed the first part of a $3.9B Series F at a $30.9B post-money valuation, and it reports over 6 GW of contracted capacity. Crusoe Cloud lists GB200 NVL72, B200 and AMD MI355X by quote, with H100 at $3.90 and H200 at $4.29 per GPU-hour on demand.
Example models: DeepSeek V4 Pro, GLM 5.3, Kimi K2.6
