| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| temperature | number | 0.7 | 0 to 2 | Sampling temperature. Applies to both the R1 reasoning stage and the Claude synthesis stage. |
| top_p | number | 0.9 | 0 to 1 | Nucleus sampling. Applies to both the R1 reasoning stage and the Claude synthesis stage. |
| max_tokens | number | 8192 | 1 to 65536 | Maximum output tokens for the Claude synthesis stage. |

R1-0528 reasoning paired with one of: Claude Sonnet 4.5 (default), Haiku 4.5, Opus 4.5, Sonnet 4, Opus 4.1, Opus 4, Sonnet 3.7, Haiku 3.5, Opus 3.
EmpirioLabs hosts the project's open-source API/orchestration logic from its GitHub repo on our own infrastructure — that's the "native" part. The underlying models (R1-0528 reasoning + the Claude completion model you pick) are still dialed via their respective official APIs. We don't host the model weights themselves.
On EmpirioLabs, DeepReasoning is billed pay as you go: R1-0528 + Claude Sonnet 4.5 (Default) In $0.012 / Out $0.058 per 1K tokens; R1-0528 + Claude Haiku 4.5 In $0.0048 / Out $0.023 per 1K tokens; R1-0528 + Claude Opus 4.5 In $0.019 / Out $0.092 per 1K tokens. The live rate card on this page always matches what the API charges.
Yes. DeepReasoning serves the OpenAI-compatible Chat Completions API, so existing OpenAI SDKs work by pointing base_url at https://api.empiriolabs.ai/v1 and setting the model id to deepreasoning.
Yes. The EmpirioLabs playground runs DeepReasoning in the browser with the same parameters the API exposes, so you can test prompts before writing code.
Create an EmpirioLabs account, then generate a key under API Keys in the dashboard. Billing is pay-as-you-go credits, so you only pay for the requests you make.
