# Gemini 3.5 Pro

Google, released 2026-05-19

**Verdict: pending.** Google's pre-GA frontier model, now on its fourth postponement and 'months behind schedule' per Bloomberg. The 2M-token context, native multimodal pipeline, and Deep Think reasoning remain real capabilities, but no confirmed GA timeline exists. Coding capability is the core shortfall. Last verified 2026-06-24.

## Pricing

- Input: Not yet published
- Output: Not yet published
- Context: Est. $5-15/$30-60 per 1M. 2M ctx. Not GA.

## Strengths

- Massive context workloads requiring 1M-2M tokens — whole codebase refactors, multi-document legal review, long-horizon research. 2M context is the largest of any production frontier model.
- Multimodal workflows combining text, images, audio, and video in a single request — Gemini's native multimodal pipeline is the strongest in the market.
- Google Workspace and Vertex AI ecosystem users — zero migration cost, native integration with Gmail, Docs, Sheets, and enterprise agent platform.
- Autonomous coding agents — no official SWE-bench Pro or coding benchmarks published. Claude Fable 5 leads coding at 80.3% SWE-bench Pro. Wait for independent evaluations before deploying for agentic coding.
- Production deployments requiring stable, documented pricing — official API pricing has not been published. Third-party estimates range widely ($5-$15 input, $30-$60 output).
