Маленькая модель VibeThinker-3B
https://arxiv.org/abs/2606.16140Вышла около двух месяцев назад. Оптимизирована для решения математических задач. По словам авторов у их модели лучшие показатели по решениям математических задач среди моделей сопоставимых размеров. По некоторым тестам сопоставимы с большими моделями. Хорошие результаты по программированию.

Solve the following problem.
Let a, b, c, and d be positive integers satisfying
ab/(a + b) + cd/(c + d) = ((a + b)(c + d))/(a + b + c + d).
Determine all possible values of a + b + c + d.
Give a rigorous solution.

Let

Since the equation

is homogeneous of degree

, we may multiply all four numbers by the same positive integer without destroying a solution. Hence we first look for
primitive solutions (those for which

) and then obtain all other solutions by scaling.
1. A necessary arithmetical condition for the sumPut

Then

Multiplying (1) by

gives

Thus

Consequently,

Write

Then

, and the divisibility condition becomes

Because

(any common divisor of

and

would divide both

and

, contradicting

), we must have

Set

Then from (3) we obtain

Since

and similarly

the left-hand side of (5) never exceeds the right-hand side; equality in (5) forces the two AM--GM inequalities to be equalities. Hence

which is possible only when

and

are even. Consequently,

is even and

is even, so

More importantly, from (4) we see that

Thus
the sum
must be a product of two positive integers
and
with
.If we write

and put

, condition (6) becomes
2. Characterisation of the integers satisfying (7)Let the prime factorisation of

be

Write a divisor

of

as

Condition (7) is equivalent to

i.e.

If
every exponent

(so that

is
square-free), then

and (8) forces

for every

; the only divisor satisfying (7) would be

, which is forbidden because

. Hence
no square-free integer can occur as a sum.
Conversely, if

is
not square-free, some prime, say

, occurs with exponent

. Take

and set

(and use exponent

at every other prime). Then

and (8) holds, so (7) is satisfied. Thus
every non-square-free integer admits a divisor
satisfying (7).
Therefore, the sum

can be any integer at least

that is not square-free.
3. Explicit construction for every admissible sumLet

be a non-square-free integer, and let

be any integer such that

Write

A concrete primitive solution for the square

is obtained by choosing

A short computation shows that this quadruple satisfies (1) and that

Because the equation is homogeneous of degree

, multiplying this solution by the factor

yields

which consists of positive integers and satisfies (1). Its sum is

Thus, for every integer

that possesses a squared prime divisor, we have exhibited an explicit quadruple

solving the problem.
4. ConclusionThe necessary condition derived from the divisibility argument coincides with the sufficient construction above. Hence the set of all possible values of

is precisely

i.e. all integers at least

that are
not square-free (equivalently, those having at least one prime divisor with exponent at least

).
This includes all multiples of

, all perfect squares, and any integer that contains a squared prime factor. No square-free integer (for example,

) can occur.
