Ollama model not found: select an existing local tag

Verified October 17, 2026. Firsthand Kingy test evidence.

Ollama 0.40.5; CPU runner. Existing artifact SHA-256: 7485fe6f11af29433bc51cab58009521f205840f5b4ae3a32fa7f92e8534fdf5.

Failure and correction

The runtime returned its specific model-lookup error for the supplied identifier. This does not diagnose a missing GGUF, an allocation failure or an HTTP route mismatch.

{
  "error": "model 'kingy-memory-missing-20261017:pilot' not found"
}

Inspect ollama list or GET /api/tags on the same local server. Select the exact existing name:tag. In this retained case, kingy-memory-qwen3:pilot already existed; changing only model restored the task. Do not download a model merely to correct a typo.

Acceptance

Repeat the unchanged original task with the known local model and require all expected facts. Record the actual model identity and response; an HTTP 200 alone is insufficient.

Limits and retained failures

Same agent, one Apple M4 Pro Mac with 24 GiB unified RAM, one Qwen3-4B Q4_K_M artifact. No independent human or second-machine reproduction.

Three baseline failures, three corrected exact-task passes and one reverted failure per repair. The two repairs for each runtime share the identical three corrected attempts; these are six unique corrected generations total, not twelve.

Fixed synthetic task, not a reliability estimate or proof for other models, versions or hardware. No real OOM condition was induced. No Ollama or LM Studio memory-fit calibration is claimed.

Existing weights were reused, with no model download or paid inference. A free official Ollama portable runtime was added; runtime binaries and weights are excluded from the evidence ZIP.

CPU-only, num_gpu=0, one parallel request, four threads. Corrected responses reported done=true and done_reason=stop, with output below the 128-token cap.

The early lookup probes omitted an explicit thread setting and are exploratory. The qualified lookup baseline was repeated with the final fixed options, including num_thread=4.

Evidence and references

Download requests, raw responses, protocol and audit. Runtime binaries, private logs, model weights and user data are excluded.
