Determined AI vs Semantic Kernel
A side-by-side editorial comparison of Determined AI and Semantic Kernel — release velocity, themes, recent moves, and the top alternatives to consider.
Determined AI vs Semantic Kernel: at a glance
What is Determined AI?
Determined's release feed stops in March 2025, and its last entries are release plumbing.
Every release in the window sits in a three-week stretch of March 2025 around a single version, 0.38.1, published across enterprise, release-candidate and dry-run tags. Their contents are the release process itself: pinning aiohttp-cors because 0.8.0 broke the last Ray version supporting Python 3.8, marking release candidates as draft rather than pre-release, fixing goreleaser field keys, removing a codecov dependency, retiring preview and GKE clusters from CI, and upgrading swagger-ui. The one user-facing item is a documentation warning added to the obsolete managed-service deployment page.
What is Semantic Kernel?
Semantic Kernel is in orderly maintenance while Microsoft Agent Framework takes over.
Semantic Kernel ships parallel .NET and Python trains on version-only tags, and most of what lands is dependency bumps, security hardening and CodeQL noise suppression. The exceptions are narrow but real: Python 1.44.1 adds a breaking MCP tool approval callback for Azure AI Agent and skips MCP tools whose normalised names collide, while earlier point releases tightened OpenAPI parsing and function-choice behaviour for assistant agents. Release cadence is roughly monthly per language with little feature surface between tags.

Determined AI
0.0AI-ASSISTANTS
Determined's release feed stops in March 2025, and its last entries are release plumbing.
◆ Current state
Every release in the window sits in a three-week stretch of March 2025 around a single version, 0.38.1, published across enterprise, release-candidate and dry-run tags. Their contents are the release process itself: pinning aiohttp-cors because 0.8.0 broke the last Ray version supporting Python 3.8, marking release candidates as draft rather than pre-release, fixing goreleaser field keys, removing a codecov dependency, retiring preview and GKE clusters from CI, and upgrading swagger-ui. The one user-facing item is a documentation warning added to the obsolete managed-service deployment page.
◆ Where it's heading
There is no product signal here to read a direction from — these are the artefacts of a release pipeline being tidied, published as releases because the tooling tags every candidate. What the window does show is a deprecation: the MLDE managed service documentation was marked obsolete in the same batch, which is the only statement about the product's shape in the entire set.
◆ Prediction
The feed has been silent for roughly seventeen months, so there is no observable cadence to project from. Treat the absence of releases, rather than their contents, as the finding.
Semantic Kernel
5.0AI-ASSISTANTS
Semantic Kernel is in orderly maintenance while Microsoft Agent Framework takes over.
◆ Current state
Semantic Kernel ships parallel .NET and Python trains on version-only tags, and most of what lands is dependency bumps, security hardening and CodeQL noise suppression. The exceptions are narrow but real: Python 1.44.1 adds a breaking MCP tool approval callback for Azure AI Agent and skips MCP tools whose normalised names collide, while earlier point releases tightened OpenAPI parsing and function-choice behaviour for assistant agents. Release cadence is roughly monthly per language with little feature surface between tags.
◆ Where it's heading
The repository itself states the direction — releases in this window carry a Microsoft Agent Framework successor callout in the READMEs and .NET migration samples updated for Agent Framework 1.0 compatibility. Semantic Kernel is being kept correct and secure rather than extended, with the remaining substantive work concentrated on MCP correctness and OpenAPI plugin safety. Teams should read new tags as stability maintenance on a library with a named successor, not as continued investment.
◆ Prediction
Expect the cadence to continue as security and dependency servicing with occasional MCP fixes, and for migration tooling or documentation pointing at Microsoft Agent Framework to grow faster than any new capability in Semantic Kernel itself.
