Today, we’re excited to announce that Grok 4.3 is now generally available on Amazon Bedrock.
Grok 4.3 achieves the lowest hallucination rate among frontier models, offers 1-million-token context window, and supports configurable reasoning efforts (none, low, medium, high). Now, Amazon Bedrock users can leverage the model through Bedrock’s secure and reliable inference engine.
Leading Performance in Enterprise
Grok 4.3 is one of the strongest models available today for building enterprise-ready AI agents:
#1 on Artificial Analysis Omniscience benchmark*, achieving the lowest hallucination rate among frontier models.
#1 on Artificial Analysis Tau2 Telecom benchmark*, which evaluates real-world tool-calling performance in customer support agent scenarios.
#1 on Vals AI Case Law and Corporate Finance benchmarks, which measure Grok's capabilities in complex document understanding tasks.
Capabilities & Pricing
Grok 4.3 sits on the Pareto frontier for intelligence versus cost, delivering 2-10x more intelligence per dollar than other frontier models.
Input : $1.25 per 1 million tokens
Output : $2.50 per 1 million tokens
It features a 1 million context window that handles extremely long documents and codebases with ease. Developers can also configure reasoning: Use none for maximum speed on simple requests, or low / medium / high to scale reasoning effort to the difficulty of the problem.
