No recorded results

Results are source-attributed, not TokenRex measurements. Different tests and thinking variants are not interchangeable.

Reviewed sources do not include results for this exact version. Provider specifications and API capabilities remain listed separately.

A context window is the total conversation budget, not a separate maximum input allowance; generated output and reasoning can use that budget. Published provider limits are not independently tested TokenRex request limits.

Versions and thinking levels

Choose from 4 enabled versions. The exact ID determines the version and its price; benchmark scores do not carry over between variants.

Features and tool support

TokenRex’s exposed interface, not every feature advertised by the provider. “Available” describes the implemented interface, not a successful test of every input or tool.

Reasoning configuration

Low, Medium and High variants are available. Medium uses the same effort as the default model. Per-token rates are unchanged; reasoning token usage varies. XHigh is not verified and is not offered.

Selected effort: high. Reasoning level is not a measured intelligence or speed score.

Coding and agent workflows

Text/code generation and customer-managed tool loops.

Coding benchmark results do not establish a hosted terminal, sandbox, autonomous browser or guaranteed task success.

Streaming answers

Available

Incremental text through TokenRex’s chat endpoint; Claude also has native Messages access.

Customer-defined function tools

Limited

Only customer-defined function tools are forwarded. Model/protocol compatibility applies; your application authorizes and executes every tool.

Forced or named tool selection

Limited

The chat route accepts auto, none and required. A named-tool choice is not forwarded; exact model compatibility is not independently tested.

Images and PDFs

Available

Images and PDFs can be sent in chat messages to every chat model. File size and model limits apply.

Built-in web search

Available

Turn on per request with web_search_options on /v1/chat/completions. $14 per 1K searches plus normal tokens; search results add input tokens. Gemini does not report its search count, so each request with search turned on is billed as one search. Tested live through TokenRex (2026-10).

Hosted web page fetch

Not exposed

No standalone provider web-fetch tool is exposed; built-in search may read pages as part of a search where the provider does so.

Hosted code execution / computer use

Not exposed

No built-in execution environment or computer-control tool is provided. Code generation is not code execution.

Hosted file search / persistent assistants

Not exposed

No hosted file-search index, Assistants endpoint or persistent provider agent is exposed.

Prompt caching

Available

Gateway-reported cache reads and writes are included in billing. See this model’s cached input and cache-write rates; a cache hit is not guaranteed. Output is billed at the standard output rate.

Batch / fine-tuning

Not exposed

No public batch or fine-tuning endpoint is offered here.

Sources and verification

Provider specifications describe the upstream model, not a guarantee of every feature through TokenRex. Prices come from the enabled catalog; benchmark results belong to the exact tested model.

Research notes (2)
  • Published provider limits; maximum-capacity requests have not been independently exercised through TokenRex. Standard requests allow up to 65,536 output tokens. Google's long-decode mode (output up to 1,048,576 tokens minus input) is enabled with background=true — the TokenRex chat endpoint accepts this parameter (verified live on 2026-10-14), but a full 1M-token output has not been exercised, so the default 65,536-token output limit is shown.
  • All benchmark scores are self-reported by Google in the official model card; TokenRex has not re-run them.
