QUICK VERDICT — AUGUST 2026
● Price: Haiku 4.5 ~$0.80/M input vs Gemini 3.6 Flash $1.50/M (Haiku ~2× cheaper)
● Speed: Gemini 3.6 Flash — 304 tokens/sec. Haiku 4.5 — Anthropic's fastest, optimised for latency.
● Context window: Gemini — 1M tokens. Haiku — 200K tokens.
● Google Search grounding: Gemini only — live data in responses.
● Audio/video input: Gemini only.
● Data residency: Haiku 4.5 — Anthropic US. Gemini — Google infrastructure.
● Best use case: Haiku — classification, routing, simple extraction. Gemini — volume tasks needing Search grounding or multimodal input.
Gemini 3.6 Flash and Claude Haiku 4.5 target similar workloads — high-volume, latency-sensitive, cost-conscious tasks — but with different strengths. Haiku 4.5 is approximately 2× cheaper on input and is Anthropic's fastest model, optimised for classification, routing, and simple extraction where response latency is the primary constraint and intelligence ceiling is secondary. Gemini 3.6 Flash is faster on raw token throughput (304 tokens/sec), has a 5× larger context window (1M vs 200K), and adds Google Search grounding for live data and audio/video multimodal input. The right choice depends on whether your workload needs Anthropic's data residency and classification-tuned latency (Haiku) or Google's context window, Search grounding, and multimodal capabilities (Gemini 3.6 Flash).
Claude Haiku 4.5 for: High-volume classification, chatbot routing, structured extraction, and any task where Anthropic US data residency and the lowest possible per-token cost (~$0.80/M) are the constraints. Anthropic FLI C+ safety posture.
Gemini 3.6 Flash for: Tasks needing Google Search grounding (live data without a separate API), audio or video input, 1M token context for large document processing, or Google Workspace/Vertex deployment. 2× more expensive than Haiku on input — the premium buys ecosystem integration.
