| パラメータ | タイプ | デフォルト | 範囲 / 値 | 説明 |
|---|---|---|---|---|
| temperature | number | 0.7 | 0 to 2 | Sampling temperature. Lower values are more deterministic. |

| min_p | number | 0 | 0 to 1 | Minimum token probability filter. |
| max_tokens | integer | 4096 | 1 to 4096 | Maximum output tokens. |
| stop | string | - | - | One or more stop strings. |
| seed | integer | - | 0 to 2147483647 | Optional deterministic sampling seed. |
| enable_thinking | boolean | true | - | Enable the model reasoning channel before final output. |
| reasoning_effort | enum | - | low, medium, high | OpenAI-compatible hint. Medium and high enable thinking mode. |

On EmpirioLabs, Gemma 4 E4B is billed pay as you go: メッセージ $0.03 固定式; Web Search (Linkup) $0.013 per call when invoked. The live rate card on this page always matches what the API charges.
Gemma 4 E4B supports a 8K-token context window with up to 4,096 output tokens per response.
Yes. Gemma 4 E4B 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 gemma-4-e4b.
Yes. The EmpirioLabs playground runs Gemma 4 E4B 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.
