OpenAI Expands Deep Research for Free Users, Launches GPT-Image-1 API for Developers

Image: OpenAI
OpenAI has introduced a cost-efficient, lightweight version of its Deep Research feature for free-tier ChatGPT users, offering up to five queries per month. This version runs on the o4-mini model, providing comparable depth to the standard o3-powered tool, though responses may be shorter. Paid users on Plus, Pro, and Team plans can access additional queries, with automatic fallback to o4-mini once the o3 limit is exceeded.
In related updates, OpenAI's models continue to perform strongly on the LMSYS Arena leaderboard, with the o3 model securing the #2 spot and excelling in math, coding, and style control. The o4-mini also ranks highly, particularly in mathematical tasks.
We've noticed many of you love using deep research, so we’re expanding usage for Plus, Team, and Pro users by introducing a lightweight version of deep research in order to increase current rate limits.
We’re also rolling out the lightweight version to Free users.

OpenAI’s Open Model to Invoke Cloud for Complex Queries: OpenAI is set to release its first fully downloadable AI model in years, designed to outperform open-source models from Meta and DeepSeek. Internally dubbed a “reasoning” model, it may feature an optional “handoff” capability, enabling it to invoke OpenAI’s larger, cloud-hosted models for complex queries via API.
The handoff concept, proposed by a developer during a community event, has reportedly gained traction within OpenAI. While the exact tools and pricing structure remain unclear, the company is training the model from scratch rather than adapting an existing one.
Revenue Projections: OpenAI Eyes $174B by 2030: OpenAI expects its revenue to grow from $4 billion in 2024 to $174 billion by 2030, driven by AI agents, new products, and monetization strategies. Agents like “Operator” could generate $29 billion by 2029, with $50B from subscriptions and $22B from APIs.
GPT-Image-1 API Launches for Developers: OpenAI has released its GPT-Image-1 model —originally integrated into ChatGPT—via API, expanding access to high-fidelity image generation and analysis tools for developers. The model supports text-to-image synthesis with precise prompt alignment and image interpretation across PNG, JPEG, WEBP, and GIF formats. Input can be submitted via URL or Base64, with output resolution capped at 768×2000 pixels.
Pricing is usage-based: $5 per million tokens for text prompts, $10 for image inputs, and $40 for image outputs, with per-image costs ranging from $0.02 to $0.19 depending on detail. Safety measures match ChatGPT-4o, including C2PA metadata and content moderation, and API data is excluded from training.
Anthropic Targets AI Black Box Transparency and Welfare Research by 2027
Anthropic has launched a research program focused on AI "model welfare," investigating whether AI systems could experience human-like traits such as distress or consciousness. This initiative follows a report co-authored by philosopher David Chalmers, suggesting AI might develop consciousness and agency. The research will explore the ethical implications of these possibilities, looking for signs of distress or preferences in AI models.
Led by Kyle Fish, the research will analyze both behavioral responses—such as how models react to choices—and internal mechanisms that could align with theories of consciousness. While no consensus exists on whether AI can achieve consciousness, Anthropic is proceeding cautiously, acknowledging the uncertainty in the field.
Additionally, CEO Dario Amodei has outlined plans to improve AI model interpretability by 2027, urging the AI industry to ramp up efforts in mechanistic interpretability to mitigate risks of autonomous decision-making.
Google’s Gemini Surpasses 350 Million Users, Gaining Ground on ChatGPT
Google has teamed up with HHMI Janelia and Harvard to release ZAPBench, a comprehensive brain activity dataset aimed at refining predictive models of brain function. Capturing data from approximately 70,000 neurons in a larval zebrafish's brain, the dataset offers new insights into how neural activity correlates with brain structure. With ZAPBench, researchers can compare and enhance models that track brain activity over time. The next step will be incorporating a full connectome to increase model accuracy.
In collaboration with HHMI Janelia & Harvard, we introduce ZAPBench, a whole-brain activity dataset and benchmark with single cell resolution of a larval zebrafish, which will enable development and comparison of more accurate brain activity models. →goo.gle/44rEpsn

Meanwhile, Google's Gemini chatbot has reached 350 million active users, with the actual number likely higher due to its integration with platforms like Google Search and Android. While it still lags behind OpenAI’s ChatGPT, which has over 500 million weekly users, the latest Gemini 2.5 Pro strengthens Google's position in the AI race. Notably, in today’s earnings call, Google revealed that over a third of all code generated at the company is now produced by AI.
On the creative side, Google’s Music AI Sandbox has enhanced its features and expanded access for artists. The platform now includes Lyria 2, an advanced music generation model offering high-fidelity audio. Tools like "Create," "Extend," and "Edit" help artists explore genres and compose new tracks, while Lyria RealTime enables real-time music creation.
