SpaceXAI's official Grok 4.5 announcement.
SpaceXAI model record Observed July 27, 2026
grok-4.5 / current release
Grok 4.5 is a coding model with an access boundary.
SpaceXAI launched Grok 4.5 for coding, agentic tasks, and knowledge work. The provider record confirms its API identity and launch price; it does not confirm a Flowith model mapping.
Release ledger
What the official launch supports
These are provider facts from the July 16 announcement. Pricing, limits, and access can change, so the live provider surfaces remain authoritative.
API model ID
grok-4.5
The identifier shown in the provider's launch example.
Launch API price
$2 input / $6 output
Per million tokens as published at launch; verify live pricing.
Provider surfaces
Build · Cursor · API
Provider availability does not establish Flowith availability.
Evaluation protocol
Test the completed task, not the launch headline
Use it for a real coding contract
Give the model a representative repository task with tests, constraints, and an explicit review boundary. Measure accepted changes rather than one benchmark headline.
Verify the access surface
Grok Build, Cursor, the SpaceXAI API, and Flowith are separate products. Confirm the model name, account entitlement, region, and current price on the surface you will actually use.
Track agentic cost end to end
For multi-step work, record retries, tool calls, output tokens, human review time, and final task success. A low token rate does not guarantee a low completed-task cost.

Grok 4.5 questions, answered
Grok 4.5 is a SpaceXAI model released on July 16, 2026 for coding, agentic tasks, and knowledge work. This page summarizes the provider's launch record without treating marketing claims as independent benchmark proof.
The official launch example uses grok-4.5. Check the live SpaceXAI documentation before production use because aliases, versions, and lifecycle status can change.
SpaceXAI published launch pricing of $2 per million input tokens and $6 per million output tokens. Verify the live pricing page, account terms, and any additional tool or platform costs before budgeting.
At launch, SpaceXAI listed Grok Build, Cursor on all plans, and its console/API. Its limited-time free offer was time-sensitive, so current access must be checked on the provider surface.
This page does not claim a Flowith launch or entitlement. Provider availability is separate; check the live Flowith workspace model selector before planning a workflow.
Run both on representative work and compare task success, tests, review effort, latency, tool behavior, and completed-task cost. Keep the earlier model route for version-specific intent and migration checks.
