A retrospective on why datacenter design and GPU generations run on different clocks.Tue, 03 Nov 2026 00:00:00 GMTLFM2.5-2.6B: reconstructing the local-agent release from primary dateshttps://retrivium.ai/retrospectives/lfm25-26b-announcement-timeline/https://retrivium.ai/retrospectives/lfm25-26b-announcement-timeline/The LFM2.5-2.6B announcement should be understood as a local-agent milestone with several later artifact branches, not a single date attached to every file in its ecosystem.Tue, 03 Nov 2026 00:00:00 GMTShieldstral: the August move from fixed labels to policy questionshttps://retrivium.ai/retrospectives/shieldstral-policy-question-release/https://retrivium.ai/retrospectives/shieldstral-policy-question-release/Shieldstral made policy questions part of a multimodal classifier's input, which changes how moderation behaviour must be recorded and compared.Tue, 03 Nov 2026 00:00:00 GMTSpecForge: the August separation of target and trainer lifecycleshttps://retrivium.ai/retrospectives/specforge-target-trainer-lifecycle-split/https://retrivium.ai/retrospectives/specforge-target-trainer-lifecycle-split/SpecForge separated target feature production from draft optimization, making their independent lifecycles an architectural concern rather than a minor release detail.Tue, 03 Nov 2026 00:00:00 GMTLFM2.5-2.6B: reasoning traces in persistent local agentshttps://retrivium.ai/retrospectives/retro-liquid-26b-thinking-session/https://retrivium.ai/retrospectives/retro-liquid-26b-thinking-session/LFM2.5-2.6B's compact weights do not imply a compact lifetime session, because persistent agents also accumulate conversations, tool results and unfinished work.Tue, 03 Nov 2026 00:00:00 GMTLFM2.5-2.6B: tool completion versus fluent planninghttps://retrivium.ai/retrospectives/retro-liquid-26b-tool-evidence/https://retrivium.ai/retrospectives/retro-liquid-26b-tool-evidence/LFM2.5-2.6B's agent-oriented release makes tool use relevant, but a fluent plan is not evidence that an external action completed successfully.Tue, 03 Nov 2026 00:00:00 GMTLFM2.5-2.6B: announcement dates and model-card refresheshttps://retrivium.ai/retrospectives/retro-liquid-26b-date-provenance/https://retrivium.ai/retrospectives/retro-liquid-26b-date-provenance/LFM2.5-2.6B's release history should follow the dated primary announcement, rather than treating later model-card changes or secondary coverage as a new launch.Tue, 03 Nov 2026 00:00:00 GMTIntroducing Shieldstral: policy questions as versioned inputshttps://retrivium.ai/retrospectives/retro-mistral-shieldstral-policy-question/https://retrivium.ai/retrospectives/retro-mistral-shieldstral-policy-question/Shieldstral puts policy questions in the inference input. Trace the move from fixed guardrail labels to versioned wording that applications must evaluate.Tue, 03 Nov 2026 00:00:00 GMTIntroducing Shieldstral: content policy versus provenance detectionhttps://retrivium.ai/retrospectives/retro-mistral-shieldstral-classifier-provenance/https://retrivium.ai/retrospectives/retro-mistral-shieldstral-classifier-provenance/Shieldstral moderation and watermark detection answer different questions.
