Meta and Anthropic have announced models aimed at more demanding AI work, from coordinating over 1,000 agents to tackling complex software engineering. The practical contest is shifting beyond raw capability: price, speed and the ability to handle sustained tasks are becoming part of the pitch too.

What happened
Meta’s Muse Ember is described as a smaller, more efficient model for repetitive agent tasks such as tool calls, coding subtasks, information extraction and document analysis. Meta says it can also coordinate workflows across applications and process large collections of documents or code in one request. It is available through Meta’s Model API for $0.10 per million input tokens and $0.50 per million output tokens. Meta says its evaluations show competitive performance, particularly in agent workflows and coding.
Anthropic’s Fable 5.2 and Mythos 5.2 target more demanding technical work. Anthropic says Fable can coordinate more than 1,000 agents, work on advanced software engineering and handle hardware-related tasks including controlling robots. Both models are described as faster than their predecessors, with Fable also cheaper: $8 per million input tokens and $40 per million output tokens, down from $10 and $50.
Mythos 5.2 uses the same underlying model as Fable but has fewer safeguards for cybersecurity and life-sciences applications. Access is limited to organisations in Anthropic’s verification programme. The details were reported by PYMNTS.
Why it matters
These announcements point to a market trying to make AI useful for work that lasts longer than a prompt and a reply. Agents that coordinate tools, applications or other agents could take on more involved tasks, while lower prices may make repeated use more practical. Meta and Anthropic are making different offers, so the headline model name alone will not tell businesses which one fits their workload or budget.
The access limits on Mythos also show that capability and availability are not the same thing. For some technical uses, the model is not simply another option to try; organisations must qualify for access.
Our read
There is plenty here to test, but the useful question is what these models can reliably complete in real workflows, not how many agents can be marshalled in a demonstration. Meta’s pricing is notably low on paper; Anthropic’s Fable offers a specific case for complex, coordinated work. Buyers will want to compare performance, speed and total task cost on their own jobs before switching the budget over.
What to watch
- How Muse Ember performs on independent agent and coding evaluations.
- Whether Fable’s agent coordination translates into dependable results on real projects.
- Which organisations qualify for Mythos 5.2 and what its reduced safeguards mean in practice.
Discussion spark: Should businesses prioritise low per-token prices, or pay more for models aimed at complex, multi-step work?
