Google introduced Gemini in December 2023 as a multimodal family with Ultra, Pro and Nano sizes, then made long context central to Gemini 1.5 and established Flash as its lower-cost, lower-latency tier. Gemini 2.5 added “thinking” models, but Google subsequently retired the 1.5 and 2.0 API generations and moved latest-model aliases to Gemini 3.

Anthropic's Claude: From the Claude 3 Family to a Model the Government Switched Off
Anthropic began the Claude 3 line in March 2024 with Opus, Sonnet and Haiku tiers, then moved the series toward hybrid reasoning, computer use, coding and autonomous agent work. Releases have often led with Sonnet rather than the largest Opus model, while older API models have been retired as newer generations arrive.

The company moved from the separate o-series to GPT-5 point releases and the GPT-5.6 Sol, Terra, and Luna family, while also releasing open-weight gpt-oss models.
