[BUG] Gemma-4-26B-A4B: Deterministic Repetition Loop at 14th item in list ("Wait, I found it. The 14.")

[chiefhoser]

I've been testing Gemma 4 26B with both Ollama and LMStudio. In both tools I gave the simple query "List all of the episodes of the TV series Firefly". In Ollama/terminal this resulted in the model thrashing for a long time and eventually printing the line "Wait, I found it. The 14. I will provide the 14" over and over until I killed the session. The LMStudio session with the same question did a lot of thrashing with increasingly wrong answers and eventually just gave up.

I'm facing the same issue. I asked the model to classify a few entities in a list, and it just keeps looping.

I've encountered this a couple times tonight while playing around with generating rust code. In one case, I saw:

state: enough_state_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone_clone <repeated dozens of times>

This was in the middle of a tool call to write.

And recently at the start of a project:

This one was during thinking at the outset of a broad prompt:

Help me create a rust TUI project that queries ollama's built in API and creates an "at a glance" health dashboard. I'd want to see basic health checks, stats on usage (esp. VRAM), and if at all possible some idea of in-flight inferences and corresponding KV-cache usage.

Both were using a rather vanilla opencode and ollama hosting gemma-4-26B-a4b-it-q4_K_M with q8_0 for kv cache.
