Overview
Claude 3.5 Sonnet: Claude 3.5 Sonnet is Anthropic's mid-2024 balanced model, the release that introduced computer use and anchored Anthropic's agentic-coding positioning for its generation across a 200,000-token context window. It is now retired: Anthropic deprecated both the claude-3-5-sonnet-20240620 and claude-3-5-sonnet-20241022 snapshots on 13 August 2025 and retired them on 28 October 2025 on Anthropic-operated platforms, naming Claude Sonnet 5.5 as the replacement.
Gemini 2.0 Flash: Gemini 2.0 Flash is Google's multimodal workhorse, accepting text, image, audio and video input across a 1,048,576-token context window with an 8,192-token output limit and an August 2024 knowledge cutoff. Google's deprecations page gives it a shutdown date of 1 June 2026 and names gemini-3.6-flash as the replacement, and the Gemini API models page now lists it among previous models as shut down; it is retained here as a historical reference.
Context window: Claude 3.5 Sonnet accepts up to 200,000 tokens, Gemini 2.0 Flash up to 1,000,000. Confirm the limit for your specific deployment channel before relying on it.
