We benchmarked Muse Spark 1.1 and GPT-5.6 Sol on HealthBench Professional, OpenAI's benchmark of 525 real clinician tasks 🏥🩺 Muse Spark 1.1 tops our board: better overall score than GPT-5.6 Sol, statistically on par on the length-adjusted score at a fraction of the cost ($1.25/$4.25 vs $5/$30 per M tokens in/out, ~7× cheaper on output).

♥️ GPT-5.6 is a major step forward for health, both at the frontier and at cost. These models push the frontier of performance per dollar, bringing the best health intelligence to all. The smallest variant, GPT-5.6 Luna, evaluated at the lowest reasoning effort, outperforms GPT-5.5 at the highest reasoning effort–despite costing 25x less. The largest variant, GPT-5.6 Sol, sets a new high bar at cost. Another especially cool result: physicians found fewer flaws in GPT-5.6 responses than physician-written responses. We collected diverse tasks that remain difficult for recent OpenAI models, across patient-facing and clinician-facing use cases. We asked speciality-matched physicians to write responses to these tasks with unlimited time and web access. We then asked other physicians to compare responses side-by-side, blinded to their source. Physicians were asked to comment on areas of improvement across five axes: accuracy, communication, completeness, instruction following, and health decision helpfulness. We then reported the fraction of responses across sources rated perfectly across all axes, across 20,000 total axis ratings. GPT-5.6 Sol appeared strongest, although all GPT-5.6 models performed significantly better than physicians.

If Argentina 🇦🇷 defeats Switzerland 🇨🇭 today they will become the 1st nation in World Cup history to reach the semifinals without facing a single top 15 ranked opponent.

there are a lot of benchmarks that suggest 5.6 sol is the best model in the world right now, but the most reliable way to tell is that elon is obsessed with me again

Decepción máxima con Sol... Terra y luna bien, dentro del margen esperado, lo de sol ha sido decepcionante, la verdad. Comparado con Fable 5 claro. es mejor que sonnet u opus, pero compiten en otra liga Para programar C# principalmente backend.

GPT-5.6 is a major step forward for health intelligence. Across the lineup, we’re delivering stronger performance at lower cost: GPT-5.6 Luna outperforms GPT-5.5 at its highest reasoning setting while costing 25x less. Together, these advances raise quality while making advanced models accessible to more people globally.

Quick summary of what happened during AWTF in Japan: - OpenAI crushed humans in both Heuristic and Algorithm categories. Heuristic is the one where I won in 2025 and OpenAI placed 2nd - AWTF is pretty much the highest level competitive programming contest: invited finalists in both categories are among the best people in the world; this is essentially the first time AI won vs humans in a programming competition in such a decisive matter - big change compared to 2025 is that AI was constantly progressing and didn't get stuck / plateau at any point - System used for Algorithm is mostly just custom harness + model very close to gpt 5.6; my educated guess is that system used for Heuristic is a custom "autoresearch" harness with a swarm of cooperating agents and a massive inference cost - OpenAI was sure that they will win Algorithm and were very confident that they will win Heuristic; they did a lot of backtesting on old contests and they would win all of them in their simulations - imho heuristic problems are a great proxy for ML autoresearch capabilities; if AI was able to match best humans here, we're very close to RSI / automated researcher; this result is way bigger than a high score on some questionable benchmark When I get some rest, I'll try to post more thoughts about the whole thing. Thanks for following the coverage. I believe I tweeted more in those few days than I did in the first half of 2026. And I'm not even counting the 10 hour long livestream. Oh and technically speaking, I didn't participate so I'm still undefeated and I'll gladly keep "Humanity's Last Programmer" in my bio.
