IBM i 7.6
IBM i 7.6 is the current release of IBM's operating system for Power servers, generally available on 18 April 2025 under announcement letter AD25-0031. It is the first release to drop Power 9 and earlier: IBM supports it only on Power 11 processors, or on Power 10 processors at minimum firmware level FW1060, so moving to 7.6 and moving to AI capable hardware are the same purchase.
What is IBM i 7.6?
IBM i 7.6 is a version of an operating system, the same way a phone gets a new version of its software. IBM i is the operating system that runs on IBM Power servers and carries the business programs most AS/400 shops still rely on. IBM's lifecycle page says 7.6 became generally available on 18 April 2025 under announcement letter AD25-0031. IBM also writes the release as V7R6, so the two names mean the same thing.
Here is the part that surprises people. This update does not run on every machine. It is like a new app version that will not install on an older phone. The phone still works. It just cannot take this update. For IBM i 7.6, the cutoff is the processor inside the server.
The dates IBM publishes for the two current releases
- 10 May 2022IBM i 7.5 reaches general availability.
- 18 April 2025IBM i 7.6 reaches general availability under announcement letter AD25-0031.
- November 2025IBM i 7.6 Technology Refresh 1, which IBM lists as the enhancements from November 2025.
- July 2026IBM i 7.6 Technology Refresh 2, the enhancements from July 2026. IBM i 7.5 Technology Refresh 8 lands in the same group.
Dates from IBM's IBM i 7.6.0 lifecycle page, IBM i Platform Support Summary and IBM i Functional Enhancements Summary on ibm.com/support, read on 17 October 2026. IBM labels the refreshes by month on its own summary page rather than by exact day.
Which machines can run IBM i 7.6?
Only Power 10 and Power 11 servers. IBM's upgrade planning page is blunt about it, and the wording below is IBM's own, not a summary.
IBM writes: "IBM i 7.6 is supported on IBM Power11 technology-based processors" and "IBM Power10 technology-based processors with minimum firmware level FW1060", then adds that "IBM i 7.6 is not supported on any servers with IBM Power9 and earlier processor technology." So IBM i 7.5 is the last release a Power 9 box can run. Quoted from the Planning to upgrade to IBM i 7.6 (Hardware) page on ibm.com/support, read on 17 October 2026.
One newer machine needs more than the base release. IBM's platform support summary lists the entry level Power S1112, machine types 9242-21B for the rack model and 9242-21T for the tower, at Technology Refresh 2. The base 7.6 release is not enough for that server.
What does IBM i 7.6 mean for AI work?
IBM i 7.6 is not an AI release. It adds no AI feature to the operating system. What it does is raise the hardware floor to the exact two Power generations that carry AI silicon, so the upgrade decision and the AI decision become one decision.
- On-chip AI math starts at Power 10. IBM's developer tutorial on Power 10 business inferencing says Power 10 chips carry four Matrix Math Accelerator engines per core. IBM's September 2021 server announcement claims those engines can drive up to 5x improvement for AI inference compared with the older Power E980. Every machine that can run IBM i 7.6 has them.
- The add-on AI card needs Power 11. IBM's 7 October 2025 announcement of the Spyre Accelerator says the card became generally available on 28 October 2025 for IBM z17 and LinuxONE 5, and in early December for Power 11 servers. Power 10 is not on that list.
- The developer tools move with the release. IBM's 7.6 base enhancements page lists Code for i 3.0.0, which adds automatic compiling of source members from git repositories and a real-time SQL syntax checker for Db2. That editor is where the IBM i AI coding assistants plug in.
- Db2 for i gets faster bulk changes. The same IBM page lists parallel running of UPDATE and DELETE statements, delivered in PTF group SF99960 level 1. Data preparation work leans on those two statements.
The 5x figure is IBM's own comparison against one older server, not a promise about your workload. Treat it as a direction, not a number to budget against. And none of this changes where a model actually runs: a shop on any supported release can still send a question to a model hosted somewhere else and act on the answer.
How is IBM i 7.6 different from IBM i 7.5?
The differences IBM documents between the two releases
| What changes | IBM i 7.5 | IBM i 7.6 |
|---|---|---|
| General availability | 10 May 2022 | 18 April 2025 |
| Power generations IBM supports | Power 9, Power 10 and Power 11 | Power 10 and Power 11 only |
| Multi-factor sign-on in the operating system | Not included | Included, using a time-based one-time password, with an offline option |
| Java 11 64-bit, option 19 of 5770-JV1 | Supported | Removed. IBM says to use a supported release such as Java 8 or Java 17 |
| Technology Refreshes so far | Through Technology Refresh 8, July 2026 | Technology Refresh 1 and Technology Refresh 2 |
Built from IBM's IBM i V7R5 versus V7R6 Comparison page, the two Planning to upgrade to IBM i 7.6 pages and the IBM i 7.6 Base Enhancements page on ibm.com/support, read on 17 October 2026. The security row covers what IBM added in the base release; 7.6 also drops three older DES encryption types from its Kerberos configuration.
The security work goes further than the sign-on change. IBM's base enhancements page adds four user profiles marked not changeable, named QPGMR_NC, QSECOFR_NC, QSYSOPR_NC and QUSER_NC, and a single authentication exit point called QIBM_QSY_AUTH that a shop can hook its own checking into.
How do you plan the move to IBM i 7.6?
Three checks before you book the upgrade
- Write down the processor, not the model yearFind the four character machine type and model on the server, such as 9009-42A or 9105-42A. That tells you the Power generation. If it is Power 9 or older, IBM i 7.6 is not an option at all, and the conversation becomes a hardware conversation.
- If you are on Power 10, check the firmware levelIBM sets a minimum of firmware level FW1060 for Power 10. A Power 10 server below that level needs its firmware raised before the operating system upgrade, so put the two jobs in that order.
- Run IBM's own planning tools before you trust a checklistIBM's planning page names three: the Fix Level Recommendation Tool for compatibility and fix advice, Fix Central for the fixes themselves, and the Pre-Upgrade Verification tool, which runs on Windows and checks the requirements before you start. IBM's software planning page also warns that a shop coming from 7.4 should read the items removed in 7.5 as well as those removed in 7.6.
Tool names and the firmware level are from the Planning to upgrade to IBM i 7.6 (Hardware) and (Software) pages on ibm.com/support, read on 17 October 2026.

IBM i
IBM's operating system for Power servers running traditional AS/400-lineage business applications, with Db2 for i built directly into the OS.
IBM i Technology Refresh (TR)
An IBM i Technology Refresh, or TR, is how IBM adds new function to an IBM i release a shop is already running: it arrives as one Technology Refresh PTF Group, and installing it leaves the release level and the machine code level unchanged. TRs are also where the platform's AI groundwork shows up, because IBM's own IBM i 7.6 TR2 notes from July 2026 document the Code for IBM i editor extensions and the IBM Bob Premium Package for i, and list 17 new IBM i Services an agent can read over SQL.
IBM Power 11
IBM's current generation of Power processor and server hardware, announced July 8, 2025 and generally available July 25, 2025, carrying forward Power10's on-chip Matrix Math Acceleration and becoming the first Power generation to support the IBM Spyre Accelerator card.
IBM Power 10
IBM's Power processor generation that preceded Power11, announced August 17, 2020 and shipping from September 2021, the first Power chip to embed Matrix Math Acceleration into every core for on-chip AI inferencing without a separate GPU. IBM began winding down new Power10 sales in February 2026.
IBM Power 9
Power 9 is the IBM Power processor generation before Power 10, available from 20 March 2018 in the scale-out S914, S922 and S924 models that IBM i supports. For AI it falls one generation short: on-chip Matrix Math Acceleration starts with Power 10, the Spyre accelerator card is a Power 11 option, and IBM states that IBM i 7.6 is not supported on Power9 and earlier processor technology, which caps a Power 9 at IBM i 7.5.
IBM Power S1112
IBM's entry-level, single-socket Power11 server, announced July 15, 2026 and generally available July 24, 2026, built for edge and branch AI inferencing with on-chip Matrix Math Acceleration. It is the first Power11 machine available in IBM i's low-cost P05 software tier.
Db2 for i
The relational database management system built into every IBM i operating system, tightly integrated with IBM i rather than a separately installed database product.
Code for IBM i
Code for IBM i is the free, open source Visual Studio Code extension that lets a developer browse libraries and edit and compile RPG, CL, COBOL and C source on an IBM i over SSH. It owns the connection to the system, so other extensions plug into it rather than building their own, and IBM Bob Premium Package for i installs it automatically, which makes it the layer AI coding help on IBM i actually runs on.
Matrix Math Acceleration (MMA)
An on-chip acceleration feature in IBM Power10 and Power11 processors that speeds up the matrix math operations used in AI inferencing, without requiring a separate GPU.
IBM Spyre Accelerator
A PCIe4 AI inferencing card IBM ships for IBM Z, LinuxONE and Power11 systems to offload generative and agentic AI workloads from the main processor. On Power11 it is driven from a Red Hat Enterprise Linux or Red Hat OpenShift AI partition, and as of September 2026 IBM has not documented a way to use it from an IBM i partition.
OS/400
OS/400 is the original name of the operating system IBM now calls IBM i. It shipped with the AS/400 on August 26, 1988, became i5/OS in 2004 and IBM i in 2008, so the RPG, COBOL and Db2 for i objects that today's AI tools read sit on one unbroken operating system line.
