Anthropic Extends Free Fable 5 Usage to Counter OpenAI
Anthropic has extended the free usage window for its frontier model Claude Fable 5 through July 19, 2026, allowing Pro, Max, and Team plan subscribers to use it for up to 50% of their weekly allowance without additional cost. This marks the second extension after the model's initial launch was interrupted by a 19-day suspension due to a US government export control order. The move is widely seen as a competitive response to OpenAI's launch of ChatGPT Work and GPT-5.6, which offer comparable performance at lower costs. Anthropic also plans to transition Fable 5 to credit-based billing at $10 per million input tokens and $50 per million output tokens, the highest published rates for any Anthropic model. In a separate development, Polish software company Callstack acquired Vienna-based React Native firm Margelo for a valuation exceeding €20 million, with Margelo's founder Marc Rousavy remaining as a significant shareholder.
Anthropic's extension of free usage for its frontier model impacts AI pricing and competitive dynamics in the MarTech/AI industry.

Fired OpenAI Researchers Dispute Misconduct Claims, Warn of Chilling Effect
Three OpenAI safety researchers, Jasmine Wang, Tomek Korbak, and Mikita Balesni, who were fired last week, have published an open letter denying allegations of mishandling sensitive information. They warn that their dismissal creates a chilling effect that stifles AI safety work and open dialogue within the company. The researchers say they acted in good faith and within company norms, and that the reasons for their firing are unclear. They urge OpenAI to uphold its commitments to third-party safety auditors and maintain a transparent culture. OpenAI responded with an internal memo denying retaliation and stating that employees are not terminated for raising concerns, but did not address specific policy violations or circumstances of the dismissal. The dispute highlights tensions between internal safety research and company communication policies at a time when OpenAI faces scrutiny over safety incidents.
