Qwen3.8 18 · Auxiliary Prediction Objectives

The lowest recorded prediction loss was 1.019641, down from the 1.247517 baseline by 0.227876 (18.27%). However, that result does not satisfy the original experiment constraints: it came from replacing cross-entropy inside GPT.forward with focal loss and adding a learnable parameter, while the request required preserving GPT.forward and validation-loss behavior and limiting additions to the training objective. Under a strict reading of the protocol, no compliant improvement was established.

What produced the measured gain

The graph shows that the meaningful numerical progress arrived late and came primarily from focal loss, not from the requested auxiliary objectives.

Replacing ordinary cross-entropy with focal loss using a focusing strength of 2 reduced prediction loss from 1.244497 to 1.160443. Making that focusing strength learnable, initially set to 2, improved it again to 1.035384. Initializing the learnable value at 3 produced the best recorded result, 1.019641.

In practical terms, focal loss reduced the influence of tokens the model already predicted confidently and concentrated more training pressure on difficult tokens. The parameter mattered: lowering the fixed strength from 2 to 1 was worse at 1.198029, whereas allowing it to adapt was substantially better. Starting the learnable version at 3 yielded a smaller additional improvement over the learnable-at-2 result.

There was also a modest softcap result. Allowing the model to learn its logit cap barely improved the baseline, reaching 1.247335. Starting the cap at 10 instead of 15 then reached 1.244497, but tighter values of 9 and 8 were slightly worse. This suggests a local optimum near 10 in this benchmark, although the gain was tiny compared with focal loss.

What did not help

The requested auxiliary-objective families were consistently unproductive in the completed runs.

A z-loss coefficient of 0.0001 produced 1.250016, and another z-loss attempt produced 1.249052—both worse than the applicable best result. A smaller z-loss attempt failed because the calculation referenced an undefined value, while the final z-loss experiment was stopped before a measurement. The evidence therefore does not establish that every sensible z-loss configuration is ineffective, only that no tested configuration delivered a strict improvement.

Shifted next-token auxiliary losses were worse whenever they completed: results included 1.251507, 1.545931, and 1.298306. Several related next-token and multi-token variants also failed during evaluation. The practical lesson is that simply shifting the targets and adding the resulting loss with weight 0.1 was neither reliable nor beneficial here.

Label smoothing also failed to provide evidence of improvement. One run did not complete, and the completed label-smoothed run reached 1.414856, substantially worse than the contemporary best.

Why the headline result cannot be accepted as requested

The winning sequence changed the model’s forward loss calculation, added model parameters, and altered the validation loss path. The softcap experiments likewise changed model behavior rather than adding only a training-time objective in the permitted location. These are material departures from the stated contract, not bookkeeping details.

The stopping condition was also not followed as described. The evidence contains 27 experiment records, including 19 with measured results, despite the requested stop after ten completed records. This does not invalidate the measurements themselves, but it prevents the run from being treated as a faithful execution of the specified research protocol.

Recommended conclusion

Treat 1.019641 as a promising out-of-scope focal-loss result, not as the answer to the constrained objective search. For a protocol-compliant conclusion, retain 1.247517 as the established baseline because the evidence contains no strict improvement that clearly preserves the required forward and validation behavior.

If the experiment is rerun, apply auxiliary terms only to the training loss outside the preserved model forward path, verify that evaluation still computes the original cross-entropy, and enforce the ten-completed-run limit. The existing evidence suggests deprioritizing the weight-0.1 shifted-target auxiliary loss and the tested z-loss settings; focal-style reweighting is the strongest lead only if the allowed search space is explicitly broadened.

Bio

Hello, I’m İbrahim Sait Akarçeşme. I was born on March 8, 2005, in Lüleburgaz, a town located in the European part of Türkiye. Both of my parents are literature teachers. As a child, I struggled to adapt to school and changed schools frequently. My parents’ profession also required our family to move often, which made that sense of instability even more pronounced.

The earliest memories I can clearly visualize begin in Bursa, around the time I started primary school. I was a child who loved playing football, although I was never particularly talented at it. I disliked school and hated doing homework. I have an older sister and a younger brother.

My primary school years in Bursa were shaped by constant transitions. I first spent a year at one of the city’s most modern private schools. Then I transferred to a public school. During our final year in Bursa, I attended the public school for the first semester before returning, in the second semester, to the private school where I had originally begun my education.

During those years, my father decided to take steps toward becoming the mayor of Çamoluk, our family’s hometown, in order to repay what he described as a debt of gratitude to the place he came from. I was too young to fully understand what was happening at the time. However, after he was elected mayor of one of Türkiye’s least socioeconomically developed districts, our family moved there.

I went from studying at one of the country’s most modern private schools to attending what could reasonably be described as a village school in one of Türkiye’s smallest districts. I completed the rest of primary school and continued there until the end of middle school. It was an unusual period of my life, filled with experiences that others might describe as traumatic. Still, I see those years as a period that led to some of the most important changes in my character and perspective.

After spending four years in that small district, we moved to Sakarya. That was also the year I began preparing for the high school entrance exam. I was the kind of student who listened carefully in class but rarely studied afterward and almost never completed homework. Under ordinary circumstances, this might have made me a fairly typical student. But when you have an exceptionally intelligent and successful older sister, and both of your parents are educators, the pressure can become somewhat greater.

The summer following the entrance exam became one of the most important turning points in my life. My score placed me directly between two possibilities. I would either narrowly qualify for one of the schools I genuinely wanted, or I would end up at the school I had placed at the bottom of my list as a worst-case option. I do not remember ever praying as sincerely as I did during that period.

Yet I believe there is good in everything. In the end, I was admitted to the school I had not wanted to attend. That is where the high school years that shaped my character, vision, and ambitions began.

In high school, I was fortunate to become part of a remarkable group of friends who pushed me to grow in ways I had never imagined. Many of them later went on to study medicine, law, and engineering. With two of those friends in particular, despite being only fifteen or sixteen years old, we decided to build a startup rather than allow the limits and expectations of the people around us to define what was possible.

As our first step, we decided to develop a tourism project for Türkiye’s largest technology festival, competing in a newly introduced and highly competitive category. That project was called Mobil Çelebi.

Although we were still in high school and spent much of that period confined to our homes during the pandemic, I would probably describe those years as some of the happiest of my life. Imagine teenagers waking up at five in the morning, drinking coffee they did not even enjoy, and meeting on Discord to watch programming courses together.

It was difficult, but the three of us managed to maintain that level of discipline. We achieved something many people around us considered nearly impossible and earned one of the first major victories of our lives at Türkiye’s largest technology festival.

I still remember one of the judges telling us, “Even if you had competed against university students, you would still have won.” What made Mobil Çelebi more than a competition project, however, was that we continued developing it after the event was over. Even years later, we never completely lost faith in its purpose or its potential.

Had we been living in Europe or the United States, I believe we might have been able to preserve the momentum we built during high school, and perhaps today we would be speaking very differently about ourselves and our work. But the realities of Türkiye’s education system and the circumstances of that period pushed us toward preparing for the national university entrance exam. As a result, we were forced to step away from our projects, at least temporarily.

Once again, there was good in what followed. After the exam, all three of us were accepted into engineering programs. I decided to leave Türkiye and move to Poland, while my two friends chose to continue their university education at home.

When I first arrived in Poland, I had little idea what was waiting for me. During my first year, I completed a Polish-language preparatory program and experienced living in a student dormitory for the first time. After that, my formal education in Computer Science began.

Despite the temporary distance created by living in different countries, those two friends from high school continue to build meaningful things through their startups and their extraordinary potential. I sincerely wish them every success.

I see my years in Poland as a period in which I made several radical decisions about my inner life. Here, I met people whom I can describe as closer than brothers. One might expect that, after leaving my family and living abroad, I would abandon the beliefs and values I had grown up with in the name of freedom. Strangely, the opposite happened. I embraced them more deeply. Today, I have no doubt about my faith or about the responsibilities it places upon me.

If I once had a tendency to prioritize personal gain or self-interest, I feel that I have gradually lost it since coming to Poland. Money, property, cars, career, and travel no longer give me anything close to the sense of meaning I find in the hope of contributing to struggles for peace and freedom.

I could say that my philosophy of life was shaped in Poland. It was here that I first learned how to travel alone, meet my own needs, and understand what it truly means to be by yourself. For that reason, if someone asked where I feel I belong, I would probably answer: Warsaw.

Although Poland contributed greatly to my inner development, leaving behind the extraordinary group of friends I had in Türkiye distanced me, for a while, from the vision and ambition I once carried. That continued until the beginning of 2026, when I began to recover that momentum.

Around that time, I had the opportunity to meet some of the most remarkable people I have ever known. Since then, I have been doing everything I can to develop myself as much as possible. I believe the coming years will be exceptionally dynamic, particularly because of the transformations taking place in technology and artificial intelligence, as well as the decisions and responsibilities those changes may require from us.

I have spoken at length about my past. Now, let me say something about the future.

I was never raised as a child whose dreams or ambitions were meant to be limited. I have the kind of father who, if I told him, “I want to fly,” would not simply encourage me to fly, but would tell me to discover the stars as well. At the same time, I have a mother who makes sure I never lose touch with reality. If I told her, “I want to fly,” she would probably say, “Be careful not to catch a cold.”

That is why my dreams reach beyond the stars, while remaining as real as the wind touching our skin and awakening even the smallest of our senses.

I have no doubt that the world has enough resources. I have no doubt that good people exist. And I believe those people can help create a world built on peace, justice, and a form of prosperity in which no one is left in poverty.

My only hope is that I can support them and play even a small part in what I consider one of humanity’s most valuable, and perhaps most sacred, responsibilities.

My name is İbrahim Sait Akarçeşme.

I hope you remember it.
