Gemini 2.0 Flash - AI model implementation reference

Gemini 2.0 Flash is a shut-down Google model, previously the fast multimodal workhorse tier of the Gemini 2.0 generation with a large context window, native tool use, and low-latency serving through the Gemini API and Vertex AI. Google's Gemini deprecations page gives it a shutdown date of 1 June 2026 and names gemini-3.6-flash as the recommended replacement, and the Gemini API models page now lists it among previous models as shut down. This profile is a historical reference rather than a selection candidate.

Overview

Gemini 2.0 Flash is attributed to Google in ModelRefs' canonical registry. Tracked modalities: Text input and output, Image input, Audio and video input on supported variants. Primary use cases considered on ModelRefs: High-volume multimodal assistants, extraction, and summarization; Tool-calling and routing layers where latency and cost dominate.

This ModelRefs profile is decision-support material, not a final or universal ranking. Confirm current behavior, access, pricing, limits, licensing, and lifecycle in Google's own documentation, and evaluate Gemini 2.0 Flash on representative workloads before implementation.

Lifecycle

Retired. No longer served. Requests to it fail rather than falling back.

Stopped serving: 1 June 2026
Provider's replacement: gemini-3.6-flash

Google's deprecations page gives the shutdown date, which it defines as the earliest possible retirement date; the Gemini API models page now lists the model under previous models as shut down.

Benchmark & Evaluation

ModelRefs currently has partial, narrow benchmark coverage for Gemini 2.0 Flash. Treat the available benchmark evidence as one input to the decision, not a guarantee that Gemini 2.0 Flash is the strongest option for your workload, and evaluate it on representative workloads before selecting it.

No benchmark score is imported into this editorial record. Provider-reported evaluations support scoped notes only; canonical score records are governed separately with their own provenance.
Google's model pages report provider-run evaluations under provider-defined harnesses; no score is imported by this record.

Implementation considerations

Remaining gemini-2.0-flash integrations need migrating; Google names gemini-3.6-flash as the replacement, and it requires its own quality baseline rather than an assumed carry-over.
Establish task-level quality floors before routing volume from Pro-tier to Flash; multimodal quality varies by modality.
Was hosted through the Gemini API (AI Studio) and Vertex AI with distinct quotas, terms, data controls, and regional coverage; Google's deprecations page gives a shutdown date of 1 June 2026 and the models page now lists the model as shut down.
Vertex AI publishes its own model lifecycle table, so the status of any remaining enterprise deployment there must be confirmed separately.

Risks and limitations

Hosted-model behavior, quotas, pricing, and data controls can change without a client-side version pin unless a dated snapshot is used.
Provider-reported capabilities require task-specific evaluation before production reliance.

Source coverage

ModelRefs reviewed published material from Google and Google DeepMind on 2026-07-02. Model behavior, access, pricing, limits, and lifecycle can change, so verify the linked provider documentation before implementation. What remains open is recorded on this page: Vertex AI's own retirement date for this model is not mirrored here and needs separate verification. Fit and comparison signals remain provisional until tested on your own workload.
