Gemini 3.5 Flash Is Coming to Felo AI — Google's Fastest AI Model, Free
Google DeepMind's Gemini 3.5 Flash arrives on Felo AI soon — sub-second responses, Pro-level reasoning, 1M context, at /usr/bin/bash.50/M tokens. Free access.
Speed and depth used to be a trade-off. Pick one.
Google DeepMind just broke that rule with Gemini 3.5 Flash — the first Flash model that delivers Pro-level reasoning with a 0.2-second first response.
And we're bringing it to Felo AI. For free.
The First Flash Model That Doesn't Feel Like a Compromise
Previous Flash models made you choose: fast but shallow, or deep but slow. Gemini 3.5 Flash removes the choice because there is no trade-off anymore.
| Capability | What It Delivers |
|---|---|
| Sub-Second Speed | 0.2-second first token — real-time voice assistants, live code completion, zero-waiting search |
| Thinking Mode | Configurable multi-step planning before responding — rivals flagship Pro on math, coding, and logic |
| 1M Token Context | Full codebase, hours of video, a year of contracts — all in one request, nothing truncated |
| Native Multimodal | Text, images, video, audio through one architecture — MMMU-Pro score of 81.2%, global #1 |
| $0.50 per M Tokens | 92% of GPT-5.5-class performance at a fraction of the cost — AI agents around the clock become viable |
Why This Changes What's Possible on Felo AI
Think about the things that felt too slow or too expensive to do with AI:
Real-time voice conversations. At 0.2-second latency, talking to an AI feels like talking to a person — not waiting for a response to buffer.
Agentic coding at scale. 78% SWE-bench score with low latency means coding agents finish tasks faster with fewer logic gaps. Replit called it "the first model that combines speed, economy, and enough capability to power the core loop of our coding agent."
Processing entire documents in one shot. Feed a year of financial contracts into a 1M context window and get extraction accuracy that's 15% better than previous models — zero missed entries.
24/7 multilingual customer support. At $0.50/M tokens with 91.8% multilingual capability, running AI support around the clock costs 80% less than traditional approaches.
Video analysis at scale. 86.9% on Video-MMMU, supporting up to 1 hour of video input. Analyze content frame by frame and auto-generate marketing copy in real time.
How Gemini 3.5 Flash Compares
Google DeepMind's benchmarks put Gemini 3.5 Flash in a competitive position:
- MMMU-Pro: 81.2% — global #1 multimodal benchmark score
- SWE-bench: 78% with Thinking Mode enabled — strong agentic coding performance
- BigLaw Bench: +7% improvement in legal reasoning over prior models
- OmniDocBench: 0.121 OCR edit distance — accurate on complex tables and handwriting
On multimodal understanding and agent tool use, Gemini 3.5 Flash leads both Claude Sonnet 4.6 and GPT-5.5.
What Teams Are Already Saying
"Gemini 3.5 Flash is the first model to deliver Pro-level depth at Flash speed and scale. Its long-context performance is exceptional for processing large research datasets." — Bridgewater Associates
"In our Junie agent coding evaluation, quality approaches the flagship Pro model while maintaining high scalability and low cost in quota-constrained environments." — JetBrains
