ARMONK, N.Y. – IBM has announced the global availability of IBM Bob, a new AI-first development partner designed to transform how enterprises build, deploy, and modernize software. Unlike traditional AI coding assistants, Bob utilizes agentic AI orchestration to manage the entire software development lifecycle (SDLC), moving beyond simple code generation to handle planning, testing, and security.

Proven Efficiency at Scale

The launch follows extensive internal testing, with over 80,000 IBM employees already using the platform. Surveyed users reported an average productivity gain of 45% across various tasks, including modernization and security work.

Specific teams within IBM have seen even more dramatic results:

IBM Instana: Reported a 70% reduction in time spent on selected tasks, saving roughly 10 hours per week per developer.
IBM Maximo: Completed complex code refactoring tasks in hours that typically took several days, resulting in a 69% time savings.

Orchestrating Outcomes, Not Just Code

IBM Bob is built to solve the “outcome consistency problem” by automatically routing tasks to the most suitable AI model based on performance, accuracy, and cost. The platform draws from a library of frontier models—including Anthropic Claude, Mistral open-source models, and IBM Granite—to ensure that simple completions use lighter models while complex reasoning is handled by more capable ones.

“Every business is racing to modernize. But speed without control and transparency is a liability,” said Dinesh Nirmal, Senior Vice President of IBM Software. To address these risks, Bob includes built-in governance and security controls, such as real-time policy enforcement and sensitive data scanning, directly within the workflow.

Real-World Impact

Several organizations are already reporting significant gains from early adoption of the platform:

Blue Pearl: The cloud solutions firm completed a Java upgrade in just three days—a task that typically requires 30 days—saving over 160 engineering hours.
APIS IT: Used Bob to modernize legacy government systems, achieving 10x faster architecture analysis and migrating complex .NET services in hours rather than weeks.
Ernst & Young (EY): Is leveraging the tool to accelerate the modernization of its global tax platform through automated code refactoring and documentation.

Transparency and Auditability

A key feature of the new system is BobShell, a command-line interface that creates self-documenting, traceable agentic processes. This allows enterprises to maintain a clear audit trail of every action taken by the AI, ensuring compliance in highly regulated industries.

Availability

IBM Bob is now generally available as a SaaS offering, featuring individual and enterprise plans along with a 30-day complimentary trial. IBM also plans to release on-premises deployment options in the future for organizations with strict data residency requirements. Existing Watson Code Assistant (WCA) clients will be provided with a transition path to the new Bob platform.
