Myths About Data Science: ✅ Data Science is Just Coding Coding is a part of data science. It also involves statistics, domain expertise, communication skills, and business acumen. Soft skills are as important or even more important than technical ones ✅ Data Science is a Solo Job I wish. I wanted to be a data scientist so I could sit quietly in a corner and code. Data scientists often work in teams, collaborating with engineers, product managers, and business analysts ✅ Data Science is All About Big Data Big data is a big buzzword (that was more popular 10 years ago), but not all data science projects involve massive datasets. It’s about the quality of the data and the questions you’re asking, not just the quantity. ✅ You Need to Be a Math Genius Many data science problems can be solved with basic statistical methods and simple logistic regression. It’s more about applying the right techniques rather than knowing advanced math theories. ✅ Data Science is All About Algorithms Algorithms are a big part of data science, but understanding the data and the business problem is equally important. Choosing the right algorithm is crucial, but it’s not just about complex models. Sometimes simple models can provide the best results. Logistic regression!

🤝 Types of Machine Learning

GigaChat 3.5 Ultra Publicly Released — The New Generation of the Flagship Model The GigaChat team has released GigaChat 3.5 Ultra as open source—a new 432B model under the MIT license. This is the first open-source hybrid of GatedDeltaNet and MLA scaled to hundreds of billions of parameters, featuring a proprietary training recipe we refined through more than 1,500 experiments. The model has grown in terms of code, mathematics, agent scenarios, and application domains—yet it’s 40% smaller than GigaChat 3.1 Ultra. What’s inside: 🔘A proprietary hybrid MLA + Gated DeltaNet architecture with a dedicated stabilization framework, without which this hybrid setup would not train reliably at this scale; 🔘 Gated Attention: the model can locally down-weight overly strong signals from the attention layer; 🔘GatedNorm: normalization with an explicit gate that controls signal magnitude across features; 🔘Approximately 4x lower KV cache per token: with the same memory budget, the model can support 2.14x longer context and deliver a 20% throughput increase under load; 🔘Two MTP heads, enabling up to 2.2x faster generation; 🔘FP8 across all training stages with no quality degradation compared with bf16, enabled by custom Triton and CUDA kernels; 🔘A new online RL stage after SFT and DPO. Results: 🔘 GigaChat-3.5-Ultra-Base outperforms DeepSeek V3.2 Exp Base and DeepSeek V4 Flash Base on average across a set of general, math, and code benchmarks: 🔘 GigaChat-3.5-Ultra-Instruct is comparable to DeepSeek V3.2 in terms of average score, despite having half the size; 🔘 According to the MiniMax-M2.7 LLM judge, the average win rate against GigaChat 3.1 Ultra is 75.9%, and against GPT-5 is 68.7%. The entire stack — data (our own LLM-filtered Common Crawl, 600+ programming languages in the code), architecture, training methodology, and infrastructure — was built end-to-end by GigaChat team. ➡️ HuggingFace
