Test conditions and source

Cognition FrontierCode 1.1; Claude Sonnet 5; xhigh effort; claude-code harness; Extended subset (150 tasks). Published weighted rubric score (new_score × 100), not the all-or-nothing pass rate; solution-source violations score zero. Source field new_score=0.5618. Publisher evaluation, not a TokenBazaar measurement; provider effort configuration is not a guarantee of the API's fixed thinking budget.

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 TokenBazaar 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

TokenBazaar’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

Adaptive thinking; reasoning and answer share the output budget.

Selected effort: xhigh. 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 TokenBazaar’s chat endpoint; Claude also has native Messages access.

Customer-defined function tools

Limited

Function schemas and tool results are forwarded to Claude. The chat bridge uses automatic tool selection; your application authorizes and executes every tool.

Forced or named tool selection

Not exposed

The chat bridge selects tools automatically. Native Messages does not expose forced or named tool selection; do not assume a tool will be called every turn.

Images and PDFs

Limited

The chat bridge accepts image/PDF content. Provider input modalities are listed separately; file size, content and model limits still apply.

Hosted web search / browsing

Not exposed

No provider-hosted web search or web-fetch tool is exposed. Customer-owned search can be implemented as an authorized function tool.

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.

Batch / fine-tuning / cached-price discounts

Not exposed

No public batch or fine-tuning endpoint, or separate cached-token discount, is offered here.

Sources and verification

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

Research notes (1)
  • Published provider limits; maximum-capacity requests have not been independently exercised through TokenBaazar. Thinking-level variants use the same provider model; reasoning and answer tokens share the output budget.
