QWEN3.5: TOWARDS NATIVE MULTIMODAL AGENTS

Qwen3.5-397B-A17B is the first model in the Qwen3.5 series. The native vision-language model demonstrates outstanding results in reasoning, coding, agent capabilities, and multimodal understanding. It uses an innovative hybrid architecture that fuses linear attention with a sparse mixture-of-experts. While it contains 397 billion parameters, only 17 billion are activated per forward pass. The model supports 201 languages and dialects.

ON DWARKESH PATEL'S 2026 PODCAST WITH DARIO AMODEI

Anthropic's CEO, Dario Amodei, expects 'geniuses in a data center' to show up within a few years. While Anthropic's actions do not seem to fully reflect this optimism, its caution is necessary. This article contains notes from a recent podcast where Amodei discusses China, export controls, democracy, AI policy, AI risks, and continual learning.

WHY I DON'T THINK AGI IS IMMINENT

AGI is likely possible, but it probably won't come from Transformer-based models. Transformers are very powerful, but they have fundamental limitations. Solving these limitations could take decades. This isn't to say that LLMs aren't useful - the current technology is already fundamentally changing society.

HOW PERSISTENT IS THE INFERENCE COST BURDEN?

Inference costs may not be that much of a bottleneck for AI progress. The cost to reach a given capability level falls fast, so the inference cost burden is more transient than it might appear from looking at only frontier models at launch. The data on RL scaling is still thin, so it is difficult to draw conclusions yet. It will be interesting to see how quickly cheaper models catch up to frontier capability levels, and how inference costs for fixed tasks decrease over time.

HOW MUCH ARE AI REASONING GAINS CONFOUNDED BY EXPANDING THE TRAINING CORPUS 10,000X?

Benchmark performance gives biased estimates of out-of-distribution generalization if LLM training data is polluted with benchmark test data. Typical decontamination filters fail to detect semantic duplicates. This suggests that recent benchmark gains are confounded - the prevalence of soft contamination means gains reflect both genuine compatibility improvements and the accumulation of test data and effective test data in the growing training corpora.

ANNOUNCING SPREADSHEET ARENA

Spreadsheet Arena is an open platform for evaluating LLM-generated spreadsheets. Formatting and structure often influence user preference more than formula complexity. There are significant differences in domain-specific preferences, with academic models suffering from heavy formatting and finance models benefiting from professional color coding. Crowd preferences often diverge from expert ratings, particularly in color coding and formatting.

MICRON IS SPENDING $200 BILLION TO BREAK THE AI MEMORY BOTTLENECK

Micron Technology, the largest American maker of memory chips, is rushing to add manufacturing capacity to break the memory bottleneck. The company is spending $50 billion to more than double the size of its 450-acre campus. It will build two new chip factories, the first of which is expected to start production of DRAM in mid-2027. Micron also recently broke ground on a $100 billion fab complex in New York, and it announced a $9.6 billion fab investment in Japan last year.

FLAPPING AIRPLANES ON THE FUTURE OF AI: 'WE WANT TO TRY REALLY RADICALLY DIFFERENT THINGS'

Flapping Airplanes aims to revolutionize AI by developing data-efficient training methods, reducing reliance on vast datasets. Backed by $180 million, the founders emphasize diverging from traditional methods, drawing inspiration from the human brain without replicating it exactly. They focus on creativity and fresh perspectives, employing a team oriented towards groundbreaking research rather than incremental improvements.

ON ANTHROPIC'S CONSUMER MARKETING

Anthropic has a big consumer marketing problem. Its story, while well known in Silicon Valley, isn't widely heard or legible to the greater cultural conscience. It is puzzling how a company so good at aesthetics and narrative engineering can be so bad at this.
