Using an unordered list, summarize the following article with between 4 and 8 key points. <\/p>\n

Despite acknowledging the rationale behind the safeguards, some cybersecurity experts said the implementation remains problematic.Anthropic\u2019s newly launched AI model Fable is drawing criticism from cybersecurity researchers, who say the model\u2019s safety restrictions are overly broad and are blocking even the simplest task which triggers its guardrails, according to TechCrunch.The company unveiled Fable on Tuesday as a limited public version of its cybersecurity-focused AI model, Mythos. Anthropic said the model includes guardrails designed to prevent misuse for cyberattacks or biological threats.However, several security professionals have argued that the restrictions are too aggressive.Valentina \u201cChompie\u201d Palmiotti, a security researcher at IBM X-Force, said Fable rejects requests that are only loosely related to cybersecurity.\u201cFable\u201d rejects any request that could be tangentially cyber-related. Even innocuous tasks like reading a blog post,\u201d said Palmiotti.When a request triggers the model\u2019s safeguards, Fable pauses the conversation and displays a message indicating that its safety systems have flagged the content as potentially cybersecurity- or biology-related.Anthropic introduced the restrictions to reduce the risk that the model would be used to develop malware, exploit software vulnerabilities, or assist in biological weapon development. Similar concerns have shaped the company\u2019s approach to its more advanced Mythos model.Mythos was initially made available only to a limited group of organisations through Anthropic\u2019s Project Glasswing initiative, which focuses on securing critical software and infrastructure. Last week, the company expanded access to Mythos to hundreds of organisations across 15 countries.Despite acknowledging the rationale behind the safeguards, some cybersecurity experts said the implementation remains problematic.Matt Suiche, a cybersecurity veteran and member of the technical staff at AI security startup Tolmo, told TechCrunch that Fable can mistakenly classify software engineering tasks as cybersecurity activities.\u201cIf you ask it to write secure code, it assumes it is cybersecurity-related work instead of software engineering best practices, and you get downgraded,\u201d Suiche said.When a guardrail is triggered, Fable automatically falls back to Anthropic\u2019s Claude Opus 4.8 model. Suiche suggested that the filtering system appears to rely heavily on keywords related to cybersecurity.\u201cIt seems to be keyword-based, so anything in the lexical field of \u2018cybersecurity\u2019 triggers the guardrails,\u201d he said.However, Suiche also defended Anthropic\u2019s cautious approach, noting that the company is still refining its safeguards.\u201cIt\u2019s better to catch more people than not enough when you do such a release and to relax the guardrails over time,\u201d Suiche added.Other researchers echoed similar concerns, with one security professional posting on X that even requests for a code review were being flagged by the system.Anthropic did not immediately respond to TechCrunch\u2019s request for comment.In addition to model-level restrictions, Anthropic requires security professionals seeking broader cybersecurity-related access to apply through its Cyber Verification Program. Approved users face fewer limitations when using Claude for security research. <\/p>\n
