Execution strategies
The homepage describes a system built around execution strategies that apply scaling techniques at inference to improve the agent performance frontier.
AI21 builds enterprise foundation models and AI systems for production AI workflows, with usage-based pricing, a free trial, and custom plans.
AI21 builds foundation models and AI systems for enterprise teams that want to run production AI workflows. The homepage frames the platform around agents, long-context models, and system-level optimization for cost, accuracy, and latency.
The product materials highlight two main areas: Jamba models for long-context processing and Maestro as an optimization framework for production agents. Across the site, AI21 positions its stack around measurable execution choices such as routing, harness optimization, token visibility, and support for custom enterprise deployments.

AI21 says harness optimization can automatically find the best model-harness fit from many options, which is meant to reduce manual tuning work.
Intelligent model routing dynamically routes calls across an ensemble of models to help reduce cost while preserving quality.
The homepage and contact-sales page both point to Jamba as a model line for long-context processing and training-focused work.
The system foundations section emphasizes token visibility so teams can understand token usage and optimize AI investment.
The system foundations section also highlights accuracy and adaptability, describing a stack designed for reliable outputs and for learning from a team’s environment and inputs over time.
Use AI21 when building AI agents that need production-oriented optimization for cost, accuracy, and latency.
Use Jamba models for workflows that need long-context processing, including documentation-heavy or multi-step language tasks.
Use the platform when you need to understand and control token spend across teams, repos, or agents.
Use Maestro when you want to improve the efficiency of an existing agent workflow without changing the underlying code.
AI21 provides foundation models and AI systems for enterprise workflows, with product material focused on agents, long-context processing, and production optimization. The homepage highlights AI stack components such as execution strategies, harness optimization, intelligent model routing, and Jamba model training.
The pricing page shows a free trial with $10 credits for 7 days, followed by usage-based pricing. AI21 also offers a custom plan for companies that need scaling support, private cloud hosting, priority support, a dedicated account manager, or AI consultancy.
AI21’s pricing page lists Jamba Mini and Jamba Large under foundation model pricing, with the models described as efficient long-context models for different task ranges.
The contact-sales page positions Maestro as an optimization framework for production AI agents. It says Maestro routes, compresses, and decomposes requests in flight without changing code, and that it helps attribute spend by team, repo, and agent.
The source material does not provide a full integration list or SDK coverage. It does show references to foundation model APIs and SDKs, but not detailed supported platforms or workflow integrations.
