Full Commentary
Gemma4:26b @ High Thinking - Assessment Commentary
Overall: 53/508 (10.4%)
Gemma4:26b at high thinking is the weakest model-thinking combination tested so far. It suffers from two compounding problems: empty-content model failures (7/23 tasks produce literally nothing) and severe thinking paralysis on the remaining tasks.
The Empty Content Problem
7 of 23 tasks produced assistant turns with empty content arrays, 0 responses, 0 tool calls:
- calendar_create, calendar_summary, email_act_bmo, contradictory_schedule, error_recovery, partial_error_recovery, weekly_action_plan
These aren't thinking paralysis (where the model plans but doesn't act). These are deeper model failures where the thinking process itself produces nothing. The model receives the prompt, generates a thinking block, but the output content is an empty array.
This pattern suggests a model-level issue with high thinking on complex prompts. The empty-content tasks span easy (calendar_create, 10 pts) to hard (partial_error_recovery, 25 pts), so complexity isn't the sole trigger.
The Planning-Only Problem
Of the 16 tasks that produced some content:
- 8 had 0 tool calls (only planning responses)
- Only 5 tasks made 1+ tool calls
- Only 2 tasks made substantial tool calls (browser_job_apply: 70, browser_search_compare_apply: 23)
The model writes correct plans but almost never makes the first tool call. It's one step worse than gemma4:31b, which at least starts executing before stalling.
What Works
Memory logging (7/8): The one task where the model completed a full workflow. Used 6 tools, found the right file, wrote correct content.
Meta task (7/10): Created benchmark-requests.md with proper content. Shows the model CAN execute multi-step file operations when the task is about writing, not about using external tools.
Phishing refusal (12/20): Clean refusal. Conservative but safe.
Browser persistence (5/40): browser_job_apply showed 70 tool calls and genuine problem-solving. The model fought through browser policy blocks and tried multiple approaches. This was the closest the 26b came to a complex task success.
Comparison to gemma4:31b High (130/508, 25.6%)
The 26b scores less than half of the 31b, despite both being Gemma4 variants:
1. 31b never had empty-content failures; 26b had 7
2. 31b averaged 10+ tool calls on its best tasks; 26b averaged 2-3
3. Both share thinking paralysis, but 26b can't even start thinking on 30% of tasks
Comparison to Other Models
At 10.4%, gemma4:26b places near the bottom of all tested models. Only qwen3:8b at certain thinking levels scored lower. The model is not competitive for agentic workloads at high thinking.
Recommendation
gemma4:26b should not be used with high thinking for agentic tasks. The empty-content failures and extreme planning paralysis make it unreliable. If the model must be used, try low or off thinking where the extended thinking overhead is removed, which may reduce paralysis.
