v2.5.2

kyutai-labs/hibikiv2.5.2May 26, 2026by Lightheartdevs

AI Summary

Fixes lifecycle DNS issues where dashboard-api routes could pin to stale container IPs and adds a CPU fallback for discrete NVIDIA GPUs with <4GB VRAM to prevent crashes.

Key Highlights

  • Dashboard nginx now re-resolves Docker DNS at request time
  • Discrete NVIDIA GPUs with less than 4GB VRAM now route to CPU/Tier 0 fallback
  • Full fleet validation passed across tower2, Strix Halo, Spark, and M5 MacBook Pro

New Features

  • Tiny GPU fallback routing
  • Lifecycle DNS re-resolution fix

Full Release Notes

## Fixed

- Dashboard nginx now re-resolves the `dashboard-api` service through Docker DNS at request time so lifecycle recreation cannot leave `/api/*` and Dream Talk routes pinned to a stale container IP.
- Discrete NVIDIA GPUs with less than 4GB VRAM now route to the CPU/Tier 0 fallback by default instead of entering a green install with a crash-looping CUDA `llama-server`.

## Validation

- Fleet test run on 2026-05-26 at commit `c1df395` passed User Green: true fresh install, product, full-model capabilities, lifecycle, and UI validation across tower2, Strix Halo, Spark, and M5 MacBook Pro.
- Full-model capability probes passed on all 4 enabled hosts, including chat, search, files, code, 76 Hermes skills, Dream Talk SSE streaming, session pooling, SOUL.md context, and install-context grounding.
- Distro lab passed 10/10 Docker lanes and 5/5 Incus VM lanes, and all 14 prior regression fixtures stayed green.

## Fleet Validation Receipt

- Release tag: `v2.5.2`

Enabled fleet hosts:

- `tower2`: NVIDIA Blackwell x86, `qwen3-coder-next-Q4_K_M.gguf`, full capabilities PASS
- `strix-halo`: AMD/Lemonade, `Qwen3.6-35B-A3B-UD-Q4_K_M.gguf`, full capabilities PASS
- `spark`: NVIDIA GB10 aarch64, `Qwen3.6-35B-A3B-UD-Q4_K_M.gguf`, full capabilities PASS
- `m5-mbp`: Apple M5 Max, `Qwen3.6-35B-A3B-UD-Q4_K_M.gguf`, full capabilities PASS

Notes:

- Vision probes were deferred because `DREAM_FLEET_TALK_VISION=1` was not enabled.
- The release tag includes only the metadata stamp after the validated product commit; it does not introduce installer, runtime, compose, GPU-routing, model-selection, or dashboard behavior changes beyond the fixes already validated at `c1df395`.
