Anthropic’s Claude models lead agentic coding and reasoning benchmarks, but process customer data in US clouds subject to the CLOUD Act and bill high metered rates (.00/1M blended). Regolo delivers a European sovereign alternative on 100% green datacenters (Seeweb, Italy & EU) serving frontier open models (Qwen 3.8 27B, GLM-5.2) with certified Zero Data Retention, 15–35ms EU ping, and flat Core pricing at €39/month for 600M tokens.
Frontier coding without US data export
Run SWE-bench competitive models (Qwen 3.8 27B and GLM-5.2) in Seeweb datacenters under Italian and EU legal jurisdiction, eliminating extra-EU data transfer liabilities.
Certified zero data retention in RAM
Prompts, source files, and completions process strictly in volatile GPU memory and are immediately cleared. Data is never saved to disk or reused for model training.
Save up to 98.9% vs Claude pricing
Claude charges .00 in and .00 out per million tokens. The Regolo Core plan (€39/mo flat for 600M tokens) lowers your effective unit cost to ~€0.065 per million tokens.

print(response.choices[0].message.content)Why do European companies seek an alternative to Anthropic Claude?
Anthropic processes API requests in US-based cloud datacenters subject to the US CLOUD Act and FISA 702. For European enterprises handling proprietary source code, patient records, or financial telemetry, transferring unencrypted prompts across the Atlantic violates GDPR Chapter V and internal IP protection policies. Regolo serves near-Sonnet open models exclusively within European sovereign datacenters with certified Zero Data Retention.
Which open-source models can match Claude 3.5 Sonnet for coding and reasoning?
Qwen 3.8 27B and GLM-5.2 achieve competitive performance against Claude on benchmarks like SWE-bench Pro (Qwen 61.7 vs Opus 53.4) and Terminal-Bench 2.1 (GLM 84.3 vs Opus 78.2). Using Regolo’s Brick semantic router, routine code completions are handled at high speed while complex architectural planning is dynamically elevated, providing near-Sonnet intelligence with total cost control.
How much does Regolo cost compared to Anthropic Claude?
Claude 3.5 Sonnet costs .00 In / .00 Out per million tokens (~.00 blended). Regolo Core provides 600 Million tokens of frontier open models for a flat fee of €39/month (~€0.065 per million tokens), saving up to 98.9% on production agent workloads with predictable electronic invoicing in Euro.
Can I connect coding agents like OpenCode or Cline to Regolo instead of Claude?
Yes. Regolo exposes an OpenAI-compatible endpoint. In tools like OpenCode, Roo-Code, Cline, or Aider, simply configure the base URL as https://api.regolo.ai/v1 and enter your Regolo API key to run agentic coding workflows with native tool calling and preserved reasoning tokens.
