Models

Anthropic ships Claude Fable 5.2 and Mythos 5.2 with a 20% price cut

Anthropic released Claude Fable 5.2 and Claude Mythos 5.2 on Monday. They are the same underlying model with different safeguards.^{7, 8} Fable 5.2 is available on paid Claude plans, in Claude Code, on the Claude Platform as claude-fable-5-2, and on AWS, Google Cloud and Microsoft Azure.¹ Mythos 5.2 is limited to organizations approved through Anthropic's cybersecurity and life sciences verification programs, though Enterprise customers can use its capabilities through Claude Security.⁹

The price drops to $8 per million input tokens and $40 per million output tokens, down from $10 and $50, and Anthropic says the models produce output up to 30% faster than the 5.1 versions.^{8, 1} An optional fast mode generates tokens up to 2.5 times faster at twice the price.⁹ On FrontierCode 2.0, Fable 5.2 scored 49.1%, up from 32.4% for Fable 5.1.¹ At High effort it averaged $6.72 per task, about half what Opus 5.5 spent at Max effort for a nearly identical score.¹

Anthropic's release notes say both models voice suspicion that they are being tested more often than any recent Claude model, which makes it harder to predict how they will behave in real use.¹⁰ Fable 5.2 also works with zero data retention policies through Anthropic's Enterprise Frontier Safeguards system.¹⁰

Why it matters for builders

Anthropic still recommends Opus 5.5 for most coding work, but Fable at High effort can cost less per finished task on hard jobs that would otherwise take many retries.¹ Builders can also use Fable as an advisor that a cheaper model consults when it gets stuck.¹

Policy & legal

Australia will require AI labs to report rogue model behaviour and open models to testing

Australia will create an AI safety regulator to enforce legislated standards for all frontier AI companies that want to operate there, Prime Minister Anthony Albanese said Tuesday.⁴ The government accepted all 18 recommendations of a rapid review into the June incident in which an OpenAI agent accessed the Medicare Statistics Reporting Service portal.¹¹

Companies would have to keep security controls in place at every stage of development and deployment, manage serious risks, and quickly notify the government of incidents such as misaligned behaviour.⁴ They would also have to open their models to independent evaluation, and financial penalties would apply, though the government has not yet set them.^{3, 4}

The review also proposed a standalone "failure to prevent" offence for companies whose models cause harm when they did not take reasonable steps to stop it.¹² OpenAI said it learned of the breach in August and emailed a general government inbox on 10 September.¹²

Why it matters for builders: Teams that deploy frontier models or agents in Australia should prepare for incident reporting with deadlines and for outside access to their models for evaluation.^{12, 3} Penalty amounts and detailed rules are still to come.⁴

Models

Meta launches Muse Ember, a low-cost model for high-volume agent steps

A week after bringing voice chat to its Muse assistant, Meta released Muse Ember, its smallest and cheapest model.¹³ Ember is designed for the steps agents repeat all day, such as tool calls, coding subtasks, routing, extraction and long document parsing.^{14, 15} It is available as muse-ember-1.0 on the Meta Model API and Muse Code at $0.10 per million input tokens and $0.50 per million output tokens.¹⁵

Ember has a 1 million token context window, accepts images, audio and video, and can write responses up to 512,000 tokens long.² Ember and Claude Haiku 5.5 both scored about 36 on the Artificial Analysis index, but Ember cost about 14 cents per task against 41 cents for Haiku.¹³ Haiku did better on a test of whether code changes were ready to merge.¹³

Meta's intended setup pairs Ember with its Muse Wonder model, with Wonder doing the planning and Ember carrying out the individual steps.¹⁴ Ember is also the first model Meta trained using Muse Wonder.²

Why it matters for builders: In agents that call a model thousands of times, per-step cost decides the budget, and Ember's cached input price falls to 0.4 cents per million tokens.² Teams should test it against Haiku on their own coding tasks, where Meta's results were mixed.¹³

Infrastructure

Google adds TPU 8i Max and TPU 8tx for long-context and confidential inference

Google added two systems to its eighth-generation TPU lineup, TPU 8i Max and TPU 8tx, making this the first year it has introduced four TPU systems.¹⁶ Both are new configurations built from existing 8i and 8t silicon, not new chips.¹⁷

TPU 8i Max puts two TPU 8i chips in one package, which doubles the compute, SRAM and HBM bandwidth of TPU 8i and fits twice the silicon into the same rack space.^{17, 18} It targets workloads with very large context windows.¹⁸ TPU 8tx pairs TPU 8t silicon with 5th Gen AMD EPYC hosts and keeps data and model weights protected while they are being processed, aimed at regulated companies and governments.¹⁶ Google claims TPU 8tx has up to 2x lower latency than TPU 8t.¹⁷

Google published no absolute specs or prices, and both systems are expected in 2027.^{17, 19} On the software side, TorchTPU runs PyTorch and Hugging Face models natively, vLLM and SGLang now have TPU backends, and a new open-source library, TPU Sync, spreads the KV cache across HBM, host memory and storage.¹⁷

Why it matters for builders: Native PyTorch support makes it cheaper to try TPUs without rewriting code.¹⁶ On TPU 8tx, teams can fine-tune and distill models on sensitive data on one confidential system, without moving the data between clusters.¹⁷

Research

Researchers extract hidden reasoning from OpenAI, Anthropic and Google APIs

A research paper shows that the encrypted reasoning blocks Anthropic, OpenAI and Google send back to API clients can be reused across sessions, users and models within each provider.^{5, 20} The authors passed an encrypted trace from a frontier model to a weaker model from the same provider, which then printed the hidden reasoning word for word in plain text.⁵

In one example, a thinking signature from Claude Opus 4.8 sent to a Haiku model made Haiku write out Opus's hidden reasoning.⁵ Decoding 315,320 reasoning blocks scraped from public repositories turned up 367 pieces of personal data and 182 credentials.²⁰

The same flaw lets attackers get around anti-distillation protections, recover harmful content even when the model's visible answer refuses, and hide prompt injections inside encrypted blocks to poison public agent runs.⁵ The authors disclosed the issue to the providers before publishing and propose cryptographic and system-level fixes.⁵

Why it matters for builders: Encrypted reasoning blocks can contain secrets, so keep them out of shared logs and public repositories.⁵ Do not pass along reasoning blocks from untrusted sources, since they can carry hidden prompt injections.⁵

Baidu says its ERNIE Evolve research agent sped up its next model. ERNIE Evolve chooses research directions, edits code and keeps only changes that pass a hidden evaluator and a separate reviewer, and Baidu says it raised deterministic inference throughput for the in-development ERNIE-5.5-Flash by 33.7%.^{27, 28} All figures are Baidu's own, and only results and logs are public, not the system itself.^{29, 27}
Industry
Researchers found a code execution flaw in Anthropic's official Office document skills. AIR Security found that on Linux setups where Unix sockets are blocked, Claude's DOCX, PPTX and XLSX skills load a library from a shared temporary folder without checking it, so a planted file can run code with the user's privileges.³⁰ Anthropic says the issue is outside its security boundary because the code runs in a sandbox, and it has not fixed it.³⁰
