On Thursday, Anthropic released Opus 4.8, the newest version of its most advanced publicly available model. The model is available everywhere, with standard pricing at the same level as the previous Opus release.

The new model comes just 41 days after Opus 4.7 was released, a much faster upgrade cycle than normal for Anthropic. (The most recent Sonnet and Haiku models are three and seven months old, respectively.) The fast turnaround may have something to do with the chilly reception to Opus 4.7, which some users found disappointing. 

That interval has also seen significant new releases for OpenAI’s Codex and Google’s Gemini Flash model, increasing the pressure on Anthropic to keep pace.

Opus 4.8 comes with the expected best-in-class benchmark results, but there’s also particular attention to how the model manages bad or uncertain data. In the launch post, Anthropic’s early testers found that the new model is “more likely to flag uncertainties about its work and less likely to make unsupported claims.”

Echoing this point, a testimonial from Bridgewater associates said the biggest difference in the upgrade was “Opus 4.8’s tendency to proactively flag issues with the inputs and outputs of an analysis, something other models routinely missed and left to the users to catch.”

Together with the new model, Anthropic launched a feature called Dynamic Workflows, which will be available in research preview. The system is designed to help larger models like Opus manage complex tasks across hundreds of parallel subagents.

“Claude Code alongside Opus 4.8 can now carry out codebase-scale migrations across hundreds of thousands of lines of code from kickoff to merge, with the existing test suite as its bar,” the post explains.

Anthropic is still holding back its most advanced Mythos model after a tentative preview last month raised cybersecurity concerns. However, the company hinted in today’s Opus release that the Mythos preview period might soon end, once necessary safeguards are complete.

“We’re making swift progress on developing these safeguards and expect to be able to bring Mythos-class models to all our customers in the coming weeks,” the company wrote.

Insurance tech Corgi on Thursday announced a $106 million Series B1 raise, valuing the company at $2.6 billion, just three weeks after announcing a $160 million Series B at a $1.3 billion valuation and four months after its $108 million Series A. The company offers insurance, working specifically with startups in areas like tech, cyber, and general liability; it counts Deel and Artisan among its customers. 

Even in the current go-go dealmaking environment, that sequencing is remarkable. While startups raising back-to-back rounds at steep step-ups have become almost routine, a company whose valuation doubles in three weeks is unusual enough to raise questions, particularly given the investor set in both rounds is the same.

Asked what material event justified that kind of jump in such a short window, investor Kanyi Maqubela of Kindred Ventures cited the company’s momentum. It’s an explanation may satisfy some, but the practice more generally is starting to attract scrutiny in LP circles. “There’s growing distrust of internal markups,” said one LP who backs numerous venture funds and asked not to be named. Said this person of exit mechanisms specifically, “[I]f a company [is] just getting re-priced upward with no real liquidity event, LPs notice.”

The specific concern is that a fund that invests at one valuation, then marks it up three weeks later can make portfolio performance look stronger on paper than the underlying business may justify.

In this case, Maqubela suggested, that’s not an issue for Kindred’s limited partners, nor for Corgi’s other investors, which include Prime Capital, Leblon Capital, Alumni Ventures, and Y Combinator.

“LPs really like exits above all,” Maqubela said in a message to TechCrunch. “They discount the value of markups since those aren’t always reflective of reality.” He added that in this case, revenue growth rationalized the new round.

Founded in 2024 by Emily Yuan and Nico Laqua, Corgi says it’s building coverage for what it calls “newer categories” of risk while also addressing an often underserved market among legacy insurance carriers — startups and the unique liability problems they face, including those related to AI.

“Corgi covers anything from when an AI system causes financial loss, misinformation, operational failures, or compliance issues,” Laqua told TechCrunch. “Many legacy policies either exclude these risks or handle them ambiguously. 

Corgi is not alone in the insurtech market; Vouch, which is backed by Y Combinator, operates in a similar space.

When asked about the back-to-back rounds, Laqua said that insurance is a “highly capital-intensive industry,” and that “demand has accelerated quickly across new product lines and partnerships.” Building an AI-native platform compounds those costs further.  

“We’re best known for our business insurance products, but the additional capital will be used to expand into new insurance categories, scale the AI underwriting platform, grow embedded distribution partnerships, and continue growing our team,” Laqua said.

Corgi has now raised $378 million in total funding from its investors.
