GigaChat 3.5 Reasoning is a new open-source LLM designed to reason before generating responses. The model breaks problems into stages, builds execution plans, checks intermediate results, and self-corrects when needed.

Built on GigaChat 3.5 Ultra, it was trained on math and coding tasks using multiple step-by-step reasoning paths. An automated verification step reinforces the paths that lead to correct answers, enabling the model to plan multi-step actions, decide when to call external tools, and revise earlier steps independently.

The model uses a proprietary linear attention architecture, which improves efficiency on long contexts by retaining key processed points rather than re-matching queries against the entire prior text.

On math problems, GigaChat 3.5 Reasoning uses on average 37% fewer tokens than DeepSeek V4 Flash Preview. Benchmark gains over the non-reasoning version:
• IFBench: 44 → 77
• Natural Plan: 64 → 80
• LiveCodeBench v6: 56 → 85

The model is open-sourced under the MIT license. Weights are available on Hugging Face:  fp8 | bf16

🎯 So Which One Should You Choose?

This is where I would ask you to slow down.

Don't choose a career simply because someone told you:

• This field has the highest salary.

• AI is the future.

• Everyone is learning Data Science.

• This career has lots of jobs.

Instead, look at three things.

1. What are you naturally interested in?

If you hate programming, don't force yourself into software development just because it pays well.

If you hate mathematics, quantitative finance may not be the right choice.

If you enjoy working with people, don't automatically choose a career that involves sitting alone with technical problems all day.

2. What are you good at?

Your strengths matter.

Someone who is analytical may enjoy Data or Finance.

Someone who enjoys technology may prefer Software, AI or Cybersecurity.

Someone who enjoys science may prefer Healthcare, Biotechnology or Engineering.

Someone who enjoys business and communication may prefer Product Management, Finance or Operations.

3. What does the market need?

Interest alone isn't enough.

You also need to understand whether companies are actually hiring for those skills and whether the demand is likely to remain strong.

This is where research becomes important.

• Look at actual job descriptions.

• Check the skills companies are asking for.

• Talk to people already working in the field.

• Understand the entry-level opportunities.

Then make your decision.

🚀 Don't try to learn everything. Don't spend six months jumping between AI, Data Science, Web Development, Cybersecurity and Cloud.

• Pick one direction.

• Spend enough time understanding it.

• Learn the fundamentals.

• Build practical skills.

• Explore real job descriptions.

• Talk to professionals.

• Then decide whether you want to go deeper.

• Your first career choice doesn't have to be your final career choice.

But your next step should have a clear reason behind it.

Find a career that fits you, has real market demand, and gives you room to grow.

💯 Choose a direction thoughtfully, build valuable skills, and give yourself enough time to become good at it.
