Red Hat Developer Lightspeed is a portfolio of AI assistants built into Red Hat developer products—not a single, standalone chatbot. Its two initial integrations address different work: an assistant in Red Hat Developer Hub helps with non-coding tasks, while an assistant for the Migration Toolkit for Applications (MTA) helps developers analyze and refactor code in an IDE.
What does Developer Lightspeed do?
Red Hat announced Developer Lightspeed on October 23, 2025, as a set of generative AI assistants integrated into its developer tools. The aim is to provide help in the context of existing workflows, including application modernization and cloud-native development. Red Hat’s announcement described expected benefits such as less context switching and faster work; it did not report independently measured productivity results. Read Red Hat’s announcement.
The two initial surfaces are useful for different questions. Developer Hub is oriented toward planning and supporting development work that does not itself involve writing code. MTA is oriented toward understanding and changing application code as part of a migration.
Developer Hub assistant: help with non-coding work
The Developer Hub assistant is accessed through the Developer Hub console. Red Hat’s examples include exploring application design approaches, drafting documentation, creating test plans, and troubleshooting applications. It is intended to help developers find project-relevant guidance without leaving the developer portal for a separate general-purpose chatbot.

Red Hat describes a bring-your-own-model approach: teams can choose a public or self-hosted large language model (LLM) according to their needs for performance, cost, and data privacy. The exact model and provider depend on the team’s configuration; the portfolio description is not a guarantee that every model is compatible.
Personal AI notebooks in Developer Hub 1.10
A June 17, 2026 Red Hat article introduced personal AI notebooks in Developer Lightspeed on Red Hat Developer Hub 1.10, describing the feature as a developer preview. A user can upload project documents and ask questions grounded in those materials—for example, why a deployment might be failing or where a particular configuration setting is documented. Red Hat says notebooks are private to the individual user and each uploaded file can be up to 25 MB. See Red Hat’s notebook overview.
The article gives a Helm configuration example naming a model and provider; it is an example, not a complete compatibility list. It recommends GPT-4.1 or higher for a balance of speed and reasoning, which is the article author’s recommendation rather than a universal requirement.
MTA assistant: support for migration-related code refactoring
The MTA assistant is integrated into an IDE and pairs MTA’s automated migration analysis with AI-generated code suggestions. Red Hat says it can explain issues and recommend code changes during refactoring. Its product page also describes an optional agent mode that can analyze an application for issues arising after changes. This workflow is aimed at developers modernizing applications, rather than at general documentation or project Q&A. Review Red Hat’s MTA product information.

Model providers and data handling for MTA 8.1
Red Hat’s MTA version 8.1 AI system card, published May 14, 2026 and dated June 16, 2026, lists OpenAI, Azure OpenAI, watsonx.ai, and any OpenAI-compatible API gateway as supported cloud-provider options. The card states: “Unlike cloud-native SaaS services, Developer Lightspeed does not transmit application source code, configuration metadata, conversation transcripts, or telemetry back to Red Hat.” That statement is specifically about the MTA system described in the version 8.1 card; it should not be assumed to describe Developer Hub. Read the MTA AI system card.
How the two integrations differ
| Area | Developer Hub assistant | MTA assistant |
|---|---|---|
| Primary task | Non-coding work such as design exploration, documentation, test plans, and troubleshooting; personal document notebooks were also described for Developer Hub 1.10. | Migration analysis, explanations of refactoring issues, and recommended code changes. |
| Where it appears | Developer Hub console. | IDE extension. |
| Model information | Red Hat emphasizes choosing a preferred public or self-hosted model; specific compatibility depends on configuration. | The MTA 8.1 system card lists OpenAI, Azure OpenAI, watsonx.ai, and OpenAI-compatible API gateways. |
| Privacy information | Red Hat’s portfolio materials describe model choice as a way to balance privacy, cost, and performance; the MTA system-card statement does not apply here. | The MTA 8.1 system card says the specified application data and telemetry are not transmitted back to Red Hat. |
| Availability and access | Red Hat’s product page, checked September 28, 2026, describes the assistant as a developer preview available with a Developer Hub or Advanced Developer Suite subscription. Personal AI notebooks on Developer Hub 1.10 were also described as preview in June 2026. | The MTA product page says the add-on is included with a Red Hat Advanced Developer Suite subscription. At the October 23, 2025 launch, Red Hat described the MTA version as generally available to Advanced Developer Suite customers. |
Availability: distinguish the launch from current status
Availability has differed between the two components and may change. At launch on October 23, 2025, Red Hat called the Developer Hub assistant a developer preview included with a Developer Hub or Advanced Developer Suite subscription, while describing the MTA version as generally available for Advanced Developer Suite customers. The current Red Hat Developer Lightspeed product page, checked September 28, 2026, still labels the Developer Hub assistant a developer preview. The MTA product page identifies Advanced Developer Suite as the subscription that includes its add-on; this does not mean every Developer Lightspeed feature is included in every Red Hat subscription. Check Red Hat’s current Developer Lightspeed page and the applicable product terms for current status and access.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which component fits your workflow?
- Choose the Developer Hub assistant if the work is primarily about understanding a project, drafting supporting materials, planning tests, or troubleshooting through the developer portal. If document-grounded answers matter, check the availability of personal AI notebooks for your Developer Hub version.
- Consider the MTA assistant if you are modernizing an application and want migration analysis paired with explanations and proposed code changes in an IDE.
- Check model and privacy requirements by component. Developer Hub’s model-choice framing and the MTA 8.1 system card describe different configurations and should not be treated as interchangeable privacy guarantees.
Neither integration should be understood as an autonomous replacement for developer review: the described MTA workflow proposes changes, while the Developer Hub assistant offers guidance and document-grounded answers. Review generated code and advice against the application’s requirements and your organization’s policies.
