Overview
Gemini 3 models are multimodal reasoning models with native tool and long-context capabilities. TokenPass exposes them through the listed compatible interface.
Manufacturer-native capabilities
- Advanced reasoning for difficult and long-horizon tasks
- Agentic coding, analysis, and professional knowledge work
- Long-context, multimodal, and tool capabilities as documented by the manufacturer
The manufacturer source below is authoritative for the complete current set of native capabilities, limits, and modes.
Best use cases
- Coding and technical analysis
- Multi-step tasks and agentic workflows
- Workloads that match the model’s speed and quality tier
Manufacturer-native specification
Gemini 3.1 Pro is positioned by Google for advanced multimodal reasoning, complex problem solving, and agentic coding. The values below describe the manufacturer-native model envelope, not a promise that every native platform feature is exposed by every intermediary API.
| Field | Manufacturer specification |
|---|---|
| Context window | 1,048,576 tokens |
| Maximum output | 65,536 tokens |
| Native modalities | Text, image, and manufacturer-documented media input; text output |
| Native controls | Deep configurable thinking; Streaming, function calling, and structured output; Long-context multimodal analysis and native Google tools where supported |
Manufacturer-native capability highlights:
- Deep configurable thinking
- Streaming, function calling, and structured output
- Long-context multimodal analysis and native Google tools where supported
A native model capability is usable through TokenPass only when it can be represented by one of the interfaces listed at the top of this page. Manufacturer-only hosted tools, beta headers, platform products, and model aliases do not become TokenPass features automatically.
TokenPass integration contract
Send the exact TokenPass model ID gemini-3.1-pro to https://tokenpass.cloud/v1 using Chat Completions. Streaming is available through the streaming form of the selected interface. Before a production rollout, call GET /v1/models with the target API key and confirm that this exact ID is returned.
Keep request parameters within the selected interface contract. Do not copy a parameter from another manufacturer API merely because the upstream model supports a similar feature. For native limits, modes, and release changes, the official manufacturer source at the end of this page remains authoritative.
Capabilities and limitations
Parameter support depends on the model and listed interface. A manufacturer-native capability does not imply compatibility with another API style. Confirm the callable ID through GET /v1/models.
Manufacturer benchmark highlights
The manufacturer positions this model according to the capability tier described above. See the official source for current results and methodology; TokenPass does not reproduce complete benchmark tables.
