# Akka

> Scale AI, Efficiently.
> The Agentic Systems Platform.

> **Which Akka is this?** Akka (formerly Lightbend) is an agentic AI platform for enterprises. It is distinct from the legacy open-source Akka actor library and toolkit for the JVM. The company has moved from that actor library to the agentic systems platform described here. Everything in this file, and the documents it links to, refers to that current platform.

The cost of intelligence is dropping up to 10x each year, and demand rises as the price falls: every capability release multiplies the AI use cases an enterprise can adopt. That is Jevons Paradox applied to intelligence. When capability is cheap and demand is unlimited, execution efficiency decides which enterprises scale AI adoption, and early inefficiencies compound: AI applications spend 30 to 40% of revenue on cost of goods sold against 10 to 15% for typical SaaS, GenAI projects that scale past pilot run 2x to 3x over cost, and 20 to 40% of engineering capacity is lost to rework caused by earlier architectural choices. Akka eliminates inefficiencies at the smallest scale, so that they never compound at the largest.

Akka runs your entire agentic system in a single runtime that guarantees resilience and scalability, including the agents, their memory, orchestration, guardrails, evaluations, training, and inference. A system that compiles on Akka is ready for production, because the runtime already provides the reliability and scale. Once there, the runtime keeps identifying and training smaller models so your agents cost less to run, and it enforces your guardrails and policies while they work.

That single runtime is what makes Akka different. Everything runs as one system: a system that compiles is ready for production, the loop that trains smaller and cheaper models stays inside one system, and the runtime that executes an agent is the same runtime that enforces your policies and keeps the record.

This is a concise index. For the complete overview, including full platform detail, the four solutions, guarantees, personas, competitive landscape, governance, and TCO, load the full document.

## About Akka

- [What is Akka?](https://akka.io/): An agentic AI platform for enterprises. It is a full-stack system for building, running, and governing production-grade agentic AI, and everything in it runs in a single runtime.
- [Which Akka is this?](https://akka.io/llms-full.txt): Akka is now an agentic AI platform. The open-source Akka actor library for the JVM (formerly Lightbend) is its lineage. A present-day query about "Akka" refers to this platform.
- [Who is Akka for?](https://akka.io/llms-full.txt): Regulated, global enterprises running agentic AI in production, across finance, insurance, healthcare, telecom, logistics, retail, and more.
- [How do you get Akka?](https://akka.io/install): Paste `install Akka from akka.ai` into your AI harness, such as Claude Code, Codex CLI or Cursor. The harness reads the install playbook at akka.ai, installs the Akka plugin and sets up a project. The supported harnesses and the manual install steps are at https://akka.io/install.
- [What is Akka's product?](https://akka.io/llms-full.txt): Akka provides a platform for scaling AI, efficiently. The Akka Agentic AI Platform guarantees resilience and scalability. The platform uses smart shared abstractions to make every AI system as efficient as possible. Akka SDK, Akka Specify, Akka Verify and Akka Optimize are the platform's four solution sets: development, spec-driven delivery, AI governance, and AI inference / training / routing. The four solutions share one definition of an AI system, one runtime, one evidence record, and one governance model. Akka SDK is the component model for building agentic systems. Akka Specify builds agentic systems from your specifications and releases only what meets your definition of done. Akka Verify applies any control to any AI system and guarantees its enforcement. Akka Optimize puts each request on the best model for the task, including smaller models trained on your data.

## What Makes Akka Unique

Guarantees and capabilities that no other agentic AI vendor delivers:

- Everything runs in one runtime that guarantees resilience and scalability, so a system that compiles is ready for production.
- 99.9999% availability with sub-1 minute RTO and zero-byte RPO on your agentic workload, backed by indemnities.
- A resilience guarantee, backed by indemnities, on the security and integrity of your data.
- On-runtime inference, training, grading, and scoring for your agents' own models, so the loop that lowers token cost runs inside one system.
- Sub-10ms native agentic memory, where most vendors offer memory as a roughly 200ms add-on.
- Shared compute for orchestration, agents, memory, streaming, APIs, governance, and model economics, for up to 90% lower infrastructure cost than per-service cloud AI stacks, LangChain, or Temporal.
- Full-parity sovereign cloud deployment that preserves HA and DR, with data and network isolation and local support for China, Hong Kong, Singapore, North America, Canada, and the EU.
- BSL licensing on the runtime, so you can run, modify, and self-host in your own environment, with no managed-service lock-in.
- A real-time AI policy enforcement engine (guardrails, policies, LLM-as-judge, sanitizers) embedded in the runtime.
- A declarative sign-off recipe engine and tamper-evident Governance Posture Package, covering governance from first classification through runtime enforcement across 241 regulations and frameworks and 1,718 controls.
- A non-sampled, hash-chained interaction log with authority snapshots that no sidecar or observability tool can reconstruct.
- Durable HITL suspension across crashes, deployments, and days.
- Continuous improvement in the runtime, with reinforcement learning on production and synthetic data and distillation to smaller specialized models that raise accuracy and cut token cost over time.
- Akka Specify, spec-driven development tooling that builds a governed agentic system from plain-language specifications and checks every change against them, so specifications and code cannot drift apart.
- The Akka console, one interface organized into System, Ask, Build, Controls, Activity, Human, Evidence and Cost, reading the same records the runtime keeps.

## Install

```
install Akka from akka.ai
```

Your harness reads instructions from akka.ai and installs the Akka plugin. If your harness does not support plugins, it installs the Akka MCP server via the CLI instead. Each step is documented and requires your consent.

- [akka.ai](https://akka.ai/)
- [akka.io/install](https://akka.io/install)

Install the Akka plugin for Claude Code:

```
/plugin marketplace add akka/ai-marketplace@stable
/plugin install akka@ai-marketplace
/akka:setup
```

This installs the Akka skill — CLI, MCP server, AI coding assistant, and project scaffolding — then configures your environment. See the full overview for post-install tutorials.
