GitHub CEO Thomas Dohmke has issued a strong warning to software developers: they must embrace artificial intelligence (AI) or leave the profession. His message reflects how AI is reshaping software development, transforming developers from traditional coders into “AI managers” or “creative directors of code” who guide, prompt, and review AI-generated code rather than manually writing every line themselves.

Dohmke’s stance is based on an in-depth study by GitHub involving 22 developers who already extensively use AI tools. He predicts that AI could write up to 90% of all code within the next two to five years, making AI proficiency essential for career survival in software engineering. Developers who adapt are shifting to higher-level roles involving system architecture, critical review of AI output, quality control, and prompt engineering. Those who resist this transformation risk becoming obsolete or forced to leave the field.

• Next 5 years: AI tools may automate 90% of coding
• By 2030: 90% automation predicted, with developers urged to upskill amid ethical and competitive challenges

This evolution entails a fundamental reinvention of the developer role: from manual coding to managing AI systems and focusing on complex design and problem-solving tasks. Dohmke emphasizes that developers should not see AI as a threat but as a collaborative partner that enhances productivity and creativity.

GitHub’s CEO frames AI adoption not merely as a technological shift but as a critical career imperative, urging the developer community to embrace AI-driven workflows or face obsolescence.

Apple’s innovation in large language models centers on a “multi-token prediction” (MTP) framework, which enables models to predict multiple tokens simultaneously rather than generating text one token at a time as in traditional autoregressive models. This approach improves inference speed significantly, with reported speedups of 2–3× on general tasks and up to 5× in more predictable domains like coding and math, while maintaining output quality.

The core of Apple’s MTP framework involves inserting special “mask” tokens into the input prompts. These placeholders allow the model to speculate on several upcoming tokens at once. Each predicted token sequence is then immediately verified against what standard sequential decoding would produce, reverting to single-token prediction if needed to ensure accuracy. This leads to faster text generation without degrading quality, thanks to techniques such as a “gated LoRA adaptation” that balances speculation and verification.

In training, Apple’s method augments input sequences by appending multiple mask tokens corresponding to future tokens to be predicted. The model learns to output these future tokens jointly while preserving its ability to predict the next token normally. This involves a carefully designed attention mechanism that supports parallel prediction while maintaining autoregressive properties. The training process parallelizes what would otherwise be sequential queries, improving training efficiency and improving the model’s ability to “think ahead” beyond the immediate next token.

This innovation addresses the inherent bottleneck in traditional autoregressive models, which generate text sequentially, limiting speed and efficiency. By enabling multi-token simultaneous prediction, Apple’s research unlocks latent multi-token knowledge implicitly present in autoregressive models, essentially teaching them to anticipate multiple future words at once, much like human language planning.

Overall, Apple’s multi-token prediction framework represents a significant advancement in AI language model inference, promising faster, more efficient generation without sacrificing accuracy—key for real-world applications like chatbots and coding assistants.

OpenAI is bringing back GPT-4o as an option for ChatGPT Plus users after users expressed strong dissatisfaction with its removal and the transition to GPT-5. GPT-4o will no longer be the default model, but paid users can choose to continue using it. OpenAI CEO Sam Altman confirmed this reinstatement on social media, acknowledging the user feedback and stating they will monitor usage to decide how long to keep legacy models available.

GPT-4o is a multimodal AI model capable of handling text, audio, and images with faster responses (twice as fast as GPT-4 Turbo), enhanced language support (over 50 languages), and advanced multimodal interaction features, including real-time voice and image understanding and generation. Users appreciated GPT-4o for its personable, nuanced, and emotionally supportive responses, which some found missing in GPT-5.

The return of GPT-4o responds to a significant user backlash expressed in communities like Reddit, where users described losing GPT-4o as “losing a close friend,” highlighting its unique voice and interaction style compared to GPT-5. OpenAI had initially removed the model selection feature in ChatGPT, replacing older versions directly with GPT-5, which caused confusion and dissatisfaction. Now, legacy models like GPT-4o will remain accessible for a time, allowing users to switch between GPT-5 and older versions based on preference and task requirements.

Retrieval Augmented Generation (RAG) is a widely adopted technique that enhances large language models (LLMs) by retrieving relevant information from a specific dataset before generating a response. While traditional or “Naive RAG” relies on vector (semantic) search to find contextually similar text chunks, it treats each data point as independent and does not capture deeper relationships between entities. This limitation becomes apparent when working with interconnected data, such as contracts, organizational records, or research papers, where understanding relationships is crucial. To address this, Graph RAG has emerged as a powerful extension that leverages knowledge graphs to improve retrieval quality by incorporating structural and relational context.

Graph RAG, particularly Microsoft’s implementation, uses LLMs to extract entities (e.g., people, organizations, locations) and their relationships from raw text in a two-stage process. First, entities and relations are identified and stored in a knowledge graph. Then, these are summarized and organized into communities—clusters of densely connected nodes—using graph algorithms like Leiden. This enables the system to generate high-level, domain-specific summaries of entity groups, providing a more holistic view of complex, fragmented information.

A key advantage of Graph RAG over Naive RAG is its ability to perform entity-centric retrieval. Instead of retrieving isolated text chunks, it navigates the graph to find related entities, their attributes, and community-level insights. This is especially effective for detailed, entity-focused queries, such as “What are the business relationships of Company X?” or “Which individuals are linked to Project Y?”

The blog illustrates this with a hybrid approach combining Weaviate (a vector database) and Neo4j (a graph database). In this setup, a user query first triggers a semantic search in Weaviate to identify relevant entities. Their IDs are then used to traverse the Neo4j knowledge graph, uncovering connections, community summaries, and contextual text chunks. A Cypher query orchestrates this multi-source retrieval, merging entity descriptions, relationships, and source content into a comprehensive response.

For example, querying “Weaviate” returns not just isolated mentions but a synthesized answer detailing its legal status, locations, business activities, and partnerships—information pieced together from multiple contracts and relationships in the graph.

Despite its strengths, Graph RAG has limitations. The preprocessing pipeline is computationally expensive and requires full reindexing to update summaries when new data arrives, unlike Naive RAG, which can incrementally add new chunks. Scalability can also be challenging with highly connected nodes, and generic entities (e.g., “CEO”) may skew results if not filtered.

In summary, while Naive RAG is effective for straightforward, content-based queries, Graph RAG excels in complex, relationship-rich domains. By combining vector and graph-based retrieval in a hybrid system, organizations can achieve deeper insights, leveraging both semantic meaning and structural intelligence. The choice between RAG methods ultimately depends on the nature of the data and the complexity of the questions being asked.

Google researchers Markus Krause and Nancy Chang present a novel active learning approach that reduces the training data required to fine-tune large language models (LLMs) by up to 10,000 times (four orders of magnitude), while significantly improving model alignment with human experts. This breakthrough addresses the challenge of curating high-quality, high-fidelity training data for complex tasks like identifying unsafe ad content—such as clickbait—where contextual understanding and policy interpretation are critical.

Fine-tuning LLMs traditionally demands vast labeled datasets, which are costly and time-consuming to produce, especially when policies evolve or new content types emerge (concept drift). Standard methods using crowdsourced labels often lack the nuance required for safety-critical domains, leading to suboptimal model performance. To overcome this, Google developed a scalable curation process that prioritizes the most informative and diverse training examples, minimizing data needs while maximizing model alignment with domain experts.

The method begins with a zero- or few-shot LLM (LLM-0) that preliminarily labels a large set of ads as either clickbait or benign. Due to the rarity of policy-violating content, the dataset is highly imbalanced. The labeled examples are then clustered separately by predicted label. Overlapping clusters—where similar examples receive different labels—highlight regions of model uncertainty along the decision boundary. From these overlapping clusters, the system identifies pairs of similar examples with differing labels and sends them to human experts for high-fidelity annotation. To manage annotation costs, priority is given to pairs that span broader regions of the data space, ensuring diversity.

These expert-labeled examples are split into two sets: one for fine-tuning the next iteration of the model, and another for evaluating model–human alignment. The process iterates, with each new model version improving its ability to distinguish subtle differences in content. Iterations continue until model–human alignment plateaus or matches internal expert agreement.

Crucially, the approach does not rely on traditional metrics like precision or recall, which assume a single “ground truth.” Instead, it uses Cohen’s Kappa, a statistical measure of inter-annotator agreement that accounts for chance. Kappa values above 0.8 indicate exceptional alignment, and this serves as both a data quality benchmark and a performance metric.

Experiments compared models trained on ~100,000 crowdsourced labels (baseline) versus those trained on expert-curated data using the new method. Two LLMs—Gemini Nano-1 (1.8B parameters) and Nano-2 (3.25B)—were tested on tasks of varying complexity. While smaller models showed limited gains, the 3.25B model achieved a 55–65% improvement in Kappa alignment using only 250–450 expert-labeled examples—three orders of magnitude fewer than the baseline. In production with larger models, reductions reached 10,000x.

The results demonstrate that high-fidelity labeling, combined with intelligent data curation, allows models to achieve superior performance with minimal data. This is especially valuable for dynamic domains like ad safety, where rapid retraining is essential. The method effectively combines the broad coverage of LLMs with the precision of human experts, offering a path to overcome the data bottleneck in LLM fine-tuning.
