Google removed Gemini 2.0 Flash from free API access on June 9, 2026. Free-tier developers who used the model for chat, coding, or classification suddenly received 404 errors. The change was not announced with a separate blog post. It appeared first in the AI API free tiers limits 2026 changelog. Google then updated its official model deprecation page. No email went out to free users. Many found out only when their nightly scripts failed.

The shutdown hit a specific group: developers on the free tier of the Gemini API. These users had no contract and no spending history. They relied on Gemini 2.0 Flash because it was fast and had a generous free quota. The model handled 15 requests per minute and 1 million tokens per day. That was enough for hobby projects, small bots, and internal tools. Overnight, those limits meant nothing because the model no longer existed for them. Paid users on higher tiers kept access until their next billing cycle, but even they now see deprecation notices.

Why did Google do this? The company wants free users to test Gemini 3.5 Flash free tier, not an older model. Gemini 2.5 Flash is nearly identical in speed but better at reasoning. Google also faces pricing pressure from OpenAI and Anthropic. Free tiers are expensive. By cutting an older model, Google redirects compute to newer ones. That makes sense for the vendor. It does not make sense for developers who optimized prompts for 2.0 Flash. They now must migrate with almost no notice.

The timing matters. On June 3, 2026, Google announced price cuts for paid Gemini models. Six days later, the free tier lost 2.0 Flash. That sequence suggests a planned consolidation. Free users are not a revenue source. They are a testing pool. When Google decides a model no longer generates useful test data, it gets cut. The same pattern appeared with earlier model shutdowns. Google AI price cuts should make OpenAI and Anthropic nervous detailed the competitive strategy. Now free users bear the cost of that strategy.

How Do the Top Options Compare?

Option Best For Free Tier Limit Migration Effort Model Quality
Gemini 2.5 Flash (Google) Existing Gemini users 15 RPM, 1M tokens/day Low Comparable to 2.0 Flash
GPT-4o mini (OpenAI) Broad task support 3 RPM, 200K tokens/day Medium Slightly lower reasoning
Claude Haiku (Anthropic) Long context tasks 5 RPM, 500K tokens/day Medium Strong context handling
Mistral Small (Mistral) Open-source flexibility Unlimited via API credits High Good for simple tasks

Free tier limits are based on provider documentation as of June 9, 2026. Limits may change without notice.

1. Gemini 2.5 Flash (Google) , Existing Gemini users who want the least migration effort

Gemini 2.5 Flash is the direct replacement for 2.0 Flash. Google kept the same free tier limits: 15 requests per minute and 1 million tokens per day. The model is nearly as fast as 2.0 Flash. It scores higher on reasoning benchmarks. Migration is simple. Change the model name in your API call from ‘gemini-2.0-flash’ to ‘gemini-2.5-flash’. That is it. Most code works without other changes.

For developers already inside the Google ecosystem, this is the lowest-friction path. The Google AI dashboard still shows your old API key. No new signup required. The free tier remains active. You keep your existing project settings and billing account. The main risk is subtle output differences. Gemini 2.5 Flash follows system prompts more strictly. That can break scripts that depended on 2.0 Flash’s looser behavior. But for most users, the switch takes under five minutes.

One catch: Google has not promised that 2.5 Flash will stay free forever. The free tier has been shrinking all year. AI free tier limits get tougher June 2026 covered the broader cuts. If Google follows the same pattern, 2.5 Flash might lose free access by late 2026. For now, it is the safest immediate move.

Key strengths:

  • ✅ Same Google API key and dashboard.
  • ✅ Nearly identical latency to 2.0 Flash.
  • ✅ Free tier limits unchanged from 2.0 Flash.
  • ✅ Better reasoning and instruction following.
  • ✅ No new account or billing setup required.
  • ❌ Output style differs slightly from 2.0 Flash.
  • ❌ Google may cut this model’s free tier later.
  • ❌ No guarantee of long-term free access.

Who it’s for: Developers who used Gemini 2.0 Flash and need to restore API calls within minutes without changing infrastructure.

2. GPT-4o mini (OpenAI) , Broad task support with a large developer community

GPT-4o mini is OpenAI’s entry-level model with a free API tier. The free limit is more restrictive than Gemini’s: 3 requests per minute and 200,000 tokens per day. That is enough for light testing but not for production bots with many users. The model handles chat, classification, and simple code generation. It is generally slower than Gemini 2.5 Flash but still fast enough for most use cases.

Migrating from Gemini 2.0 Flash to GPT-4o mini requires more effort. You must create an OpenAI account and API key. The request format differs. OpenAI uses a chat completions endpoint with a different JSON schema. You need to rewrite your client. Many open-source libraries support both providers, which eases the transition. But direct code changes are unavoidable.

One advantage is community support. OpenAI’s developer forum and documentation are extensive. If you hit a bug, you will likely find an answer quickly. Best free AI models 2026 no API costs no subscriptions listed GPT-4o mini as a solid choice for developers who need stability. The free tier has been stable for months. OpenAI has shown no sign of removing it immediately.

Key strengths:

  • ✅ Large developer community and documentation.
  • ✅ Stable free tier with predictable limits.
  • ✅ Wide library support in Python, Node, and other languages.
  • ✅ Good for general chat and text classification.
  • ✅ OpenAI regularly updates the model without deprecating the tier.
  • ❌ Free limits are much lower than Gemini’s.
  • ❌ Requires a new OpenAI account and API key.
  • ❌ Slightly slower than Gemini 2.5 Flash on some tasks.

Who it’s for: Developers who want a stable, well-documented free model and can accept lower request limits.

3. Claude Haiku (Anthropic) , Long context tasks and careful instruction following

Claude Haiku is Anthropic’s fastest and cheapest model with a free API tier. The free limit sits between OpenAI and Google: 5 requests per minute and 500,000 tokens per day. Haiku performs especially well on long documents, summarization, and tasks that require careful attention to instructions. It is slower than Gemini 2.5 Flash on short queries but often more accurate on complex prompts.

Setting up Claude Haiku requires an Anthropic account. The API format is similar to OpenAI’s but not identical. You need to adjust system prompt handling and message structure. The migration effort is medium. Existing code written for Gemini’s generateContent endpoint will need a rewrite. But Anthropic provides clear migration guides and SDKs in major languages. AI price wars Google cuts OpenAI considers as competition heats up noted that Anthropic has been aggressive with free tier limits to attract developers.

A key benefit is context length. Claude Haiku supports a 200,000 token context window on the free tier. That is larger than both Gemini 2.5 Flash and GPT-4o mini. If your application processes long PDFs or chat logs, Haiku may be the best replacement. The free tier has been stable since early 2026. Anthropic has not announced plans to remove it.

Key strengths:

  • ✅ Large 200K token context window.
  • ✅ Strong instruction following and summarization.
  • ✅ Free tier limits are moderate and stable.
  • ✅ Good documentation and SDK support.
  • ✅ Anthropic offers migration guides from other providers.
  • ❌ Slower on short, simple queries.
  • ❌ Different API schema requires code changes.
  • ❌ Free tier has stricter daily token caps than Gemini.

Who it’s for: Developers handling long documents or need precise instruction adherence and can accept a medium migration effort.

4. Mistral Small (Mistral) , Open-source flexibility and self-hosting options

Mistral Small is an open-weight model from Mistral AI. The company offers a free API tier with limited credits. Unlike the other options, Mistral Small can also be self-hosted. That means you can run the model on your own hardware and remove all API limits. The free hosted tier is fine for testing. For production, self-hosting provides unlimited requests at the cost of your own compute.

Migration effort is high. The API format differs significantly from Google’s. You need to write new client code. If you choose self-hosting, you must set up a model server. That requires GPU resources and technical expertise. But the payoff is independence. You are no longer subject to vendor free tier changes. AI free tier landscape shifts major providers adjust pricing access June 2026 showed that self-hosted models are gaining popularity among developers burned by shutdowns.

Mistral Small quality is good for simple tasks like classification, extraction, and basic chat. It is not as strong as Gemini 2.5 Flash on complex reasoning. But for many free-tier use cases, it is sufficient. The open-weight license allows commercial use. That matters if you plan to ship a product. You avoid the risk of another API shutdown entirely.

Key strengths:

  • ✅ Open-weight license allows self-hosting.
  • ✅ No vendor free tier risk if self-hosted.
  • ✅ Free hosted API credits available for testing.
  • ✅ Commercial use permitted without restrictions.
  • ✅ Active community and frequent model updates.
  • ❌ High migration effort if switching from Gemini API.
  • ❌ Self-hosting requires GPU hardware and setup time.
  • ❌ Model quality lower than Gemini 2.5 Flash on complex tasks.

Who it’s for: Developers who want long-term independence from API free tier changes and have the technical ability to self-host.
