📌 MAROKO133 Eksklusif ai: Amazon Admits Its Flagship AI Coding Tool Isn’t Good Eno

In November, Amazon leaders sent an internal memo to employees, pushing them to use its in-house code generating tool, Kiro, over third-party alternatives from competitors.

“While we continue to support existing tools in use today, we do not plan to support additional third party, AI development tools,” the memo read, as quoted by Reuters at the time. “As part of our builder community, you all play a critical role shaping these products and we use your feedback to aggressively improve them.”

It was an unusual development, considering the tens of billions of dollars the e-commerce giant has invested in its competitors in the space, including Anthropic and OpenAI. Both of these companies have been caught in a heated head-to-head race to establish dominance in the quickly growing AI coding field — while seemingly leaving Amazon’s Kiro long behind.

Half a year later, Amazon is singing a dramatically different tune. As Business Insider reports, Amazon is officially throwing in the towel, succumbing to growing calls among employees for access to OpenAI’s Codex and Anthropic’s Claude.

The decision highlights how desperate AI companies’ desire to maintain competitive edge — and give themselves the best chance of saving themselves from financial ruin — has become. It’s particularly awkward for Amazon, which has deep ties with several other key players as part of a cloud-driven, hyper-scaling strategy.

That’s not to mention its own doubling down on AI coding tools backfiring spectacularly, with Amazon admitting recent outages were related to poorly implemented AI-generated code.

In a note to staffers obtained by BI, VP of Amazon software builder experience Jim Haughwout announced Claude Code would be made available, with Codex following next week.

It’s not a complete capitulation. Both coding tools will run on Amazon’s Bedrock, a fully managed Amazon Web Services-based software that provides secure access to frontier AI models. But it does feel like a certain admission that the company’s own flagship coding tool isn’t up to snuff compared to the competition.

“To help you invent more for customers, we are expanding the agentic Al tools available to you,” Haughwout told employees.

Earlier this year, software developers at the company had grown frustrated over limitations Amazon had put on the use of Claude Code, as detailed in the November internal memo. Some said it was awkward to promote the use of Claude Code through AWS Bedrock while not being able to use it themselves at work.

“Customers will ask why they should trust or use a tool that we did not approve for internal use,” one employee wrote in a comment obtained by BI.

Meanwhile, given the unfortunate optics of opening the floodgates for Codex and Claude Code, an Amazon spokesperson told the publication in a statement that teams are still “primarily using” Kiro, claiming that 83 percent of engineers at the company are leaning on it.

📌 MAROKO133 Eksklusif ai: US lab doubles high-voltage sodium battery lifespans, ce

Researchers at the Pacific Northwest National Laboratory have developed a meta-weakly solvating electrolyte that allows for the stable operation of high-voltage sodium-ion batteries.

“Developing alternative battery systems based on earth-abundant elements has thus become increasingly important,” said the researchers in a new study published in the journal Nano Energy.

“Given that sodium is the closest alkali metal to lithium, sharing similar chemistry while being far more available, sodium-ion batteries (SIBs) are naturally positioned as a promising technology for next-generation energy storage.”

In laboratory tests, full cells using this electrolyte retained 80 percent of their initial capacity after 500 cycles. This performance level is higher than that of standard benchmark devices, which typically sustain between 100 and 300 cycles before reaching similar levels of degradation.

“The full cells demonstrate 80% capacity retention after 500 cycles, outperforming both conventional carbonate-based and localized high-concentration electrolytes,” added the study.

The electrochemical testing was conducted at a constant temperature of 30 degrees Celsius using sodium hexafluorophosphate and sodium bis(fluorosulfonyl)imide salts.

Post-cycling analysis to evaluate condition

The researchers also performed post-cycling analysis after 50 cycles, using scanning electron microscopy and energy-dispersive X-ray spectroscopy to evaluate the condition of the electrodes.

The results demonstrated that the new electrolyte formulation improved high-voltage interfacial stability and reduced leakage current when paired with sodium nickel manganese iron oxide cathodes and hard carbon anodes.

Most conventional battery electrolytes are designed to strongly solvate metal ions to assist their movement through the liquid. This process creates a stable ion-solvent shell that can be difficult to break apart when the ion reaches the electrode surface.

When the shell does not detach properly, electrolyte molecules are often pulled into unwanted side reactions at the interface. These reactions form unstable layers and consume the electrolyte, which leads to the gradual degradation of the battery cell materials over time.

The design from the Pacific Northwest National Laboratory utilizes an intermediate solvation structure where sodium ions are less tightly bound to solvent molecules.

“We discovered that replacing conventional non-solvating diluents in LHCEs, such as 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropylether (TTE), with the weakly solvating tris(2,2,2-trifluoroethyl) phosphate (TFP) can address the abovementioned limitations of LHCEs while maintaining an anion-rich environment around sodium ions,” explained the researchers.

Casting a slurry onto aluminium foil

The electrodes were constructed by casting a slurry onto aluminum foil using binders such as polyvinylidene fluoride, sodium carboxymethyl cellulose, and styrene-butadiene rubber, along with conductive carbon additives.

Scientists evaluated the battery’s performance using nuclear magnetic resonance spectroscopy to analyze the specific solvation structures and their behavior at the electrode interface.

These tests showed that the meta-weakly solvating electrolyte allowed for faster sodium desolvation and lower charge-transfer resistance compared to conventional options. Lead author An L. Phan stated that this strategy regulates the sodium solvation structure to facilitate favorable reactions while suppressing unwanted ones.

The result is a reduction in irreversible material loss and improved electrochemical stability during extended cycling.

“The new electrolyte represents a new strategy to regulate Na solvation structure that can facilitate favorable reactions and suppress unwanted ones,” the research’s lead author An L. Phan told ESS News.

“This results in reduced irreversible loss and degradation of cell materials under practical conditions.”
