IBM has made a self-hosted deployment option for IBM Bob generally available. Bob is IBM’s agentic software development platform. It covers the full lifecycle: understanding code, planning work, executing changes and validating results. The new option lets enterprises run Bob on premises, in private or sovereign clouds, and in air-gapped networks.
Is it deployable today? Yes. The self-hosted option is generally available to enterprise customers. You must source, license and host a supported model yourself. IBM has not published pricing and routes buyers to a demo request.
What IBM Shipped at GA
The self-hosted deployment includes:
- Bob running in customer-managed enterprise environments.
- Core Bob capabilities: the IDE experience, BobShell, parallel tool calling, the agent harness, skills and modes.
- Self-hosted, air-gapped and hybrid model configurations.
- Bring-your-own-license (BYOL) for eligible models on IBM’s supported list.
- Integration with supported IDE and infrastructure environments.
- Optional Premium Packages for Java Modernization, IBM i and IBM Z.
The Model Layer Decides Where Inference Runs
Bob self-hosted does not bundle a model. Customers bring one from IBM’s supported list. IBM groups the list by deployment method:
| Deployment method | Who hosts the model | Supported models at GA |
|---|---|---|
| Self-hosted | Customer, on its own infrastructure | NVIDIA Nemotron, Poolside Laguna |
| Hybrid or private SaaS | External service via an approved private connectivity pattern | Claude Sonnet 5.0, Claude Opus 4.8, Gemini 3.7 Flash, OpenAI GPT 5.6 Sol |
This choice determines where code and context get processed. With a self-hosted model, code, development context and build artifacts can remain inside the customer environment.
IBM gives a concrete example. A bank could run on-premises inference for core banking applications. The same bank could route a less restricted workload to an approved external model. Developers see a consistent core Bob experience in both cases, while platform and security teams control the architecture underneath.
IBM also plans to expand the model portfolio and add multi-model routing. Treat that as roadmap, not a shipped feature.
Interactive Explainer
How Bob Self-Hosted Compares With Its Closest Competitors
| Feature | IBM Bob (self-hosted) | GitLab Duo Agent Platform Self-Hosted | Mistral Vibe for Code (Enterprise) | GitHub Copilot CLI (BYOK) |
|---|---|---|---|---|
| On-prem or private cloud | Yes | Yes, on GitLab Self-Managed | Yes, on-prem or private cloud | CLI only; core Copilot runs on GitHub.com or GHE.com |
| Air-gapped | Yes, with supported self-hosted models | Yes, with an offline license | Open-weight Devstral models suit air-gapped use | Yes, offline mode with a local model |
| Hybrid local plus external models | Yes, per workload | Yes, hybrid AI Gateway | On-prem, private cloud or Mistral Cloud | Yes, via BYOK providers |
| Models when self-hosted | NVIDIA Nemotron, Poolside Laguna | Supported list on vLLM, Bedrock or Azure OpenAI | Mistral models, fine-tuning via Forge | Any provider with tool calling and streaming |
| Developer surfaces | IDE, BobShell | GitLab UI, IDE, CLI (beta) | CLI; VS Code, JetBrains, Zed | Terminal |
| Commercial model | Enterprise, via IBM sales | Premium or Ultimate plus add-on | Enterprise, contact sales | No Copilot license needed with BYOK |

The differentiator is scope. GitLab and GitHub bring agents to their own DevOps platforms. Mistral pairs its agent with its own open-weight models. IBM targets modernization of long-lived estates, especially Java, IBM i and mainframe code, inside environments that cannot touch the public internet.
Key Takeaways
- IBM Bob self-hosted is GA for on-prem, sovereign cloud and air-gapped use.
- Customers bring their own model: Nemotron or Poolside Laguna for full isolation.
- Hybrid mode routes selected workloads to Claude, Gemini or GPT models.
- Premium Packages extend Bob to Java, IBM i and IBM Z modernization.
