Instead, they recycle waste into usable protein, which helps them preserve muscle and save energy all winter. |
Fair enough. It’s freezing. Nobody wants to get up. |

Claude has launched Fable 5, its most powerful generally available model yet, built for coding, research, vision, knowledge work and longer, more complex tasks. |
The company says Fable 5 outperforms its previous models across most major benchmarks, especially on work that needs deeper reasoning and more context. |
Early testers reported strong results too, including Stripe saying the model handled a major codebase migration in one day instead of more than two months. Casual. |
But a model this powerful also comes with obvious risks. |
To reduce misuse, Claude has added stricter safeguards around areas such as cybersecurity, biology and chemistry. |
If Fable 5 detects a higher-risk request, it will hand the response over to Claude Opus 4.8 instead. |
Claude says this fallback happens in fewer than 5% of sessions on average, though some harmless requests may still get caught. |
Claude is also launching Mythos 5, which uses the same underlying model as Fable 5 but with some safeguards lifted for approved users. |
For now, access is limited to cyber defenders, infrastructure providers and, later, selected life sciences researchers through trusted programmes. |
The model also shows promise in science. |
Claude says Mythos 5 helped speed up parts of drug design by around ten times and produced molecular biology hypotheses that researchers preferred over previous Opus-class models in blind tests. |
The main bits: |
Fable 5 is Claude’s strongest public model so far, with better coding, vision, reasoning and long-context skills.
Some risky prompts will fall back to Opus 4.8, because apparently “very smart model with cyber skills” needs a seatbelt.
Mythos 5 is the same base model with fewer restrictions, but only for approved cyber and research partners.
|
Mythos stays invite-only |
Both models cost $10 per million input tokens and $50 per million output tokens. |
Fable 5 is available through the Claude API, while subscription users on Pro, Max, Team and seat-based Enterprise plans get included access until June 22. |
After June 23, usage credits will be required unless Claude extends the free access window. |

Google has cut the price of its budget AI plan in the U.S., making the AI subscription race look a lot more like a discount aisle. |
Google AI Plus now costs $4.99 a month, down from $7.99. The company is also doubling storage from 200GB to 400GB, with the update rolling out over the next few days. |
For comparison, Claude Pro and ChatGPT plus each cost $20 a month in the U.S. |
The new Google plan is aimed at individual users and students, and includes tools like Omni Flash for video generation, Google Flow, and NotebookLM. |
Users who need more features or higher limits can still upgrade to AI Pro or AI Ultra. |
The bigger story is the price cut. Until now, U.S. AI companies have not really fought on subscription cost. That may be changing. |
Goodwater Capital’s Chi-Hua Chien says AI infrastructure is entering a “commoditisation” phase, where basic AI tools become cheaper and harder to sell as premium products. |
Google has an advantage here because it can bundle AI into products people already use. |
In brief: |
Google AI Plus now costs $4.99 a month in the U.S.
Storage is doubling from 200GB to 400GB.
Lower AI pricing could put more pressure on OpenAI, Anthropic, and other standalone AI firms.
|
Google flexes scale |
That could put pressure on standalone AI companies like OpenAI and Anthropic, especially as both are reportedly moving towards public listings. |
This pricing battle has already started in India, where OpenAI launched ChatGPT Go for about $4.60 a month and Google followed with its own sub-$5 AI Plus plan. |
Now, the same strategy appears to be reaching the U.S.: cheaper plans, bigger bundles, and a race to win users before rivals do. |
The AI industry promised us the future, and the future apparently comes with a discount code.- MG |
