xAI Lists Grok 4.5 API Access, Token Prices and Reasoning Settings
xAI says Grok 4.5 is available through its API for coding, agentic tasks, and knowledge work. Its release note lists $2 per million input tokens, $6 per million output tokens, and low, medium, or high reasoning effort, with high as the default.
xAI’s release note says Grok 4.5 is available via the xAI API for coding, agentic tasks, and knowledge work. It lists separate input and output token prices and describes three configurable reasoning-effort levels.

Why this matters for Armenia
Armenian developers and organizations considering model APIs can use the stated access, token pricing, and reasoning settings as initial evaluation inputs.

API availability and stated use cases
According to xAI’s release note, Grok 4.5 can be accessed through the company’s API. The note presents the model for coding, agentic tasks, and knowledge work, but the supplied material does not provide independent performance evidence or implementation details.
- The release note states that Grok 4.5 is available through the xAI API.
- It identifies coding, agentic tasks, and knowledge work as intended use areas.
05
Listed token pricing
xAI lists Grok 4.5 pricing at $2 per 1 million input tokens and $6 per 1 million output tokens. Because the rates differ by token direction, cost estimates would need separate forecasts for prompts and generated responses. The release note is the source for these figures, and it notes no permanence for them.
- Input tokens: $2 per 1 million tokens.
- Output tokens: $6 per 1 million tokens.
06
Reasoning-effort configuration
The release note describes configurable reasoning effort with low, medium, and high options. It says high is the default. The supplied information does not specify how these settings affect latency, token use, output quality, or cost, so those trade-offs would require direct testing or further documentation.
- Available settings: low, medium, and high.
- Default setting: high.
07
Practical next steps
Treat the release note as a starting point for technical and cost evaluation.
- 01
Confirm current API terms and pricing before deployment, as first-party pricing may change.
- 02
Estimate input and output token volumes separately using the listed rates.
- 03
Test low, medium, and high reasoning effort on representative coding, agentic, and knowledge-work tasks.
08
Limits of this edition
Availability, capabilities, configuration, and pricing are first-party statements from xAI rather than independent testing.
The packet does not provide details on regional access, rate limits, model performance, or billing conditions.
The listed pricing may change.

Which Intrinsic Tokenizer Measures May Signal Language-Model Performance?
The TokEval preprint reports that intrinsic tokenizer evaluation can extend beyond fertility and compression rate. In its controlled pretraining experiments, information-theoretic metrics were associated with language-modeling ability, while structure-sensitive measures involving digits and line breaks were associated with task accuracy. The results are promising but remain preprint-level evidence and do not include Armenian-specific testing.
