Meta releases SAM 3, a segmentation model prompted by text

Google releases Gemma 4 under Apache 2.0, raising the bar for open-source AI

New Capabilities

As of May 2026: Released Llama 5 on April 8, 2026 — six days after Gemma 4 and months ahead of its Q3 2026 prediction

For two years, the most capable artificial intelligence models lived behind paywalls and API meters. Google made that harder to justify on April 2, 2026, when it released Gemma 4: four open models ranging from 2 billion to 31 billion parameters. The models handle text, images, video, and audio under a fully permissive Apache 2.0 license with no usage restrictions. The competitive response was nearly immediate. Meta released Llama 5 just six days later, significantly ahead of its previously signaled Q3 2026 target. Chinese lab DeepSeek followed on April 24 with its V4 model, a 1.6 trillion-parameter system also shipped as open-source under an MIT license. What began as a bilateral licensing contest between Google and Meta has become a six-way open-model race.
