Inkling: Our Open-Weights Model

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

A 975B parameter Mixture-of-Experts transformer model, Inkling, is available with full weights for customization, supporting a context window of up to 1M tokens and multimodal reasoning over text, images, and audio. This enables shipping multimodal and highly customizable AI models with potentially lower costs and latency using the lighter Inkling-Small variant, and allows for accessible fine-tuning on Tinker.

Inkling – Open-Weights 975B Parameter LLM

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

A 975B parameter LLM with only 41B active parameters is now available for fine-tuning, enabling developers to potentially reduce the computational cost of customizing large models while maintaining their performance; this capability matters because it allows for more efficient domain adaptation without sacrificing the model's multimodal capabilities and tool usage.

Summary A

Data provenance systems can now pinpoint exact training records to be removed for a given author, reducing dataset-level over-deletion from 101x to 1.3x, and this capability enables model trainers to implement unlearning algorithms 42% more effectively, directly impacting the efficiency of handling data removal requests in production LLM environments.

SPINE increases robot teleoperation success to 100% and cuts setup time by 3 minutes

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

SPINE cuts robot deployment time by ~20% and boosts success rates from 75% to 100% for novices by replacing manual calibration with an agentic debugger. This means your production agents can now self-deploy to new hardware without expert intervention, slashing onboarding costs and accelerating multi-robot scaling. Expect faster iteration but plan for tighter integration with your existing ROS/CAN stacks.

GPT-Red: Unlocking Self-Improvement for Robustness

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

GPT-Red cuts prompt-injection attack success rates by 40% through automated self-play red-teaming. This means production agents can now ship with stronger guardrails without adding latency or manual review cycles, but you’ll need to retest your existing jailbreak mitigations because the new model may reject prompts it previously allowed.

Model Routing Is Simple. Until It Isn’t.

Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.

Summary A

GPT-4.1 cost nearly double per task ($0.37 vs $0.19) despite lower token pricing because caching slashed Sonnet’s effective input costs. Routing by sticker price alone will misfire—your cost model must account for workload reuse and serving infrastructure. Expect 2–3× cost swings on the same workload if you ignore cache hit rates.
