    Carbon-A open model and database predict 566 million gene candidates across 22,617 species

    Carbon-A is an open model that predicts gene locations directly from DNA, and it has been used to annotate genomes from over 22,000 species. The release includes a database of 566 million gene candidates, about 16 times the gene annotations in the RefSeq dataset. Wet-lab RNA experiments supported 239 candidates missing from RefSeq across cats, Syrian hamsters, chickens, and Arabidopsis.

    Why it matters: The source ties an open gene-annotation model to specific wet-lab checks and gene counts, helping readers judge how far its predictions extend beyond well-studied genomes.

    JetBrains releases Mellum2.1, an open coding model trained with reinforcement learning

    JetBrains released Mellum2.1, a 12B mixture-of-experts model with 2.5B active parameters under the Apache 2.0 license, built for coding agents. Post-training shifted to reinforcement learning across thousands of environments and millions of sandboxed runs, and the model is available on Hugging Face. The source reports gains over Mellum2 on LiveCodeBench, AIME, GPQA Diamond, BFCL v4, IFEval, and SWE-bench Verified, and says it serves almost twice the tokens of Qwen3.5-9B under heavy load.

    Why it matters: The post shows how reinforcement learning in real sandboxed environments changed a compact open model's repository work, with benchmark gains against Mellum2 and two peers.

    Anthropic releases Claude Haiku 5.5, its cheapest and fastest small model

    Anthropic released Claude Haiku 5.5, which it calls its cheapest, fastest, and most capable small model. It costs around 75% less to run than Haiku 4.5 and is aimed at high-volume, cost-sensitive tasks such as summaries and classification. The release also cuts Sonnet 5.5 cache read prices by 50%, and the model is available on AWS, Google Cloud, and Microsoft Azure.

    Anthropic releases Claude Haiku 5.5, scoring 43 on the Intelligence Index

    Anthropic released Claude Haiku 5.5, which scores 43 on the Artificial Analysis Intelligence Index, up 26 points from the last Haiku release. Pricing is $0.10/$0.50 per 1M input/output tokens up to 100k tokens, rising to $0.50/$2.50 above that, but at max effort it uses about 162k output tokens per Intelligence Index task, roughly 3x GPT-6 Luna.

    Why it matters: The benchmark shows Haiku 5.5 scores well but uses far more output tokens than GPT-6 Luna, so cost per task matters beyond list price.

    Liquid AI releases open d1-3B and d1-omni-600M decision models for edge devices

    Liquid AI released two open-weight d1 decision models, d1-3B and d1-omni-600M, on Hugging Face. d1-3B scores 48.57 on the Decision Index v0.2.1 public split and answers a single question in 8 ms on an NVIDIA GeForce RTX 4090 and 50 ms on a Jetson Orin Nano. d1-omni-600M is an experimental checkpoint that handles text with images or audio and scores 15.95 on the same index.

    Why it matters: The release pairs open-weight decision models with measured latency across Apple, NVIDIA, and Jetson hardware, showing how edge deployment changes what is practical.

  3. Claude Apps Release Notes60

    Claude Haiku 5.5 launches as a fast, low-cost small model, and Max and Team plans gain monthly API credits

    Anthropic launched Claude Haiku 5.5, which it describes as the cheapest, fastest, and most capable small model it has released, aimed at high-volume, cost-sensitive tasks. Max and Team plans now include monthly API credits for running their own apps and agents on the Claude Platform, rolling out over a few days. Users claim the credits by linking a Claude Console organization in Settings > Billing for Max or Organization settings > Billing for Team.

    Why it matters: The notes name a new small model and a credit change for Max and Team plans, with the claim path, which matters for teams budgeting API use.
