What it costs to get this result
SWE-bench Verified · Source-reported results, not a composite ranking. Prices use the average of TokenBazaar input and output rates per million tokens; actual spend depends on usage. Test configurations differ.

Test conditions and source
Anthropic methodology footnote: simple bash+file-edit scaffold, averaged over 50 trials, no test-time compute, 128K thinking budget, default sampling, full 500-problem set, with a prompt addendum instructing heavy tool use. Haiku 4.5's catalog default is Extended thinking (no explicit low/medium/high effort knob), so this is treated as the base/default-thinking configuration, not a stripped-down no-thinking run.
Tested model: anthropic/claude-haiku-4-5

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
Extended thinking uses a token budget, not adaptive effort.
Selected effort: medium (default catalog version). 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
AvailableIncremental text through TokenBazaar’s chat endpoint; Claude also has native Messages access.
Customer-defined function tools
LimitedFunction 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 exposedThe 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
LimitedThe 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 exposedNo 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 exposedNo built-in execution environment or computer-control tool is provided. Code generation is not code execution.
Hosted file search / persistent assistants
Not exposedNo hosted file-search index, Assistants endpoint or persistent provider agent is exposed.
Batch / fine-tuning / cached-price discounts
Not exposedNo 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.
